Description

Technical Field

[0001] The present disclosure relates to a parts purchase assistance device, a parts purchase assistance method, and a parts purchase assistance program. Background Art

[0002] For example, when a prospective buyer (hereinafter, sometimes referred to as a "user") purchases a device component, generally, the following steps need to be taken between the prospective buyer and the supplier. Here, as an example of a prospective buyer, a device manufacturer or the like can be cited.

[0003] First, the prospective buyer prepares a rough specification of the component, presents the rough specification, and requests the supplier to make an estimate. The supplier prepares an estimate based on the rough specification and presents it to the prospective buyer. The prospective buyer adjusts the specifications and places an order with the supplier who requested the estimate.

[0004] Thus, in the past, many processes were required until the order was placed, so ordering parts required time and effort. Estimates can only be obtained from suppliers that the prospective purchaser has inquired about. Therefore, for example, even if there is a supplier that provides the same parts with better conditions (for example, low price, short delivery time, good service, etc.), there is a disadvantage that the supplier cannot be found. Moreover, on the supplier side, in the case of low-priced parts in small cases, the sales volume and profit are small relative to the effort of making estimates, which is sometimes not cost-effective. Therefore, it may lead to disadvantages for prospective purchasers such as delayed response to other cases and the price provided being estimated to be higher.

[0005] In the past, as a system for reducing the process and effort of purchasing parts, there is a system disclosed in Patent Document 1, for example. In this system, when a manufacturer sends drawing data of a part to a manufacturing entrustment support device, the manufacturing entrustment support device analyzes the drawing data to determine the processing possibility of the part, entrusts multiple processors who can process the part with an estimate, and responds to the manufacturer with the estimated price. In this way, in the manufacturing entrustment support device disclosed in Patent Document 1, the manufacturing entrustment support device mediates the transaction between the manufacturer and the processor, thereby reducing the burden of both parties related to the procurement of parts.

[0007] Patent Document 1: Japanese Patent No. 6462945 Summary of the invention

[0008] Problems to be solved by the invention

[0009] However, the manufacturing entrustment support device disclosed in Patent Document 1 is a system dedicated to processed products and cannot be immediately applied to the arrangement of equipment parts. In other words, in addition to constraints such as design pressure, operating pressure, design temperature, and operating temperature, it is necessary to decide on the purchase of equipment parts based on parameters unique to the fluid delivery system, such as flow rate and pressure loss. In this way, when selecting parts, a large amount of information and calculations are required, and it is difficult to arrange parts that meet all constraints in the manufacturing entrustment support device disclosed in Patent Document 1.

[0010] In addition, conventionally, EC websites that can easily purchase parts online are known, but these EC websites only list parts and are not suitable for purchasing equipment parts that must be selected in consideration of constraints and parameters unique to fluid transport systems.

[0011] The present disclosure has been made in view of such circumstances, and an object of the present disclosure is to provide a parts purchase support device, a parts purchase support method, and a parts purchase support program that can easily purchase equipment parts accompanying equipment construction.

[0038] Hereinafter, an embodiment of a parts purchase support device, a parts purchase support method, and a parts purchase support program according to an embodiment of the present disclosure will be described with reference to the drawings.

[0039] The component purchase assistance device of this embodiment is, for example, a device suitable for assisting the purchase of equipment components that require engineering in a fluid delivery system. Here, "engineering in a fluid delivery system" refers to, for example, the planning, design, and procurement of a system for conveying a medium such as gas, liquid, or solid assembled in the equipment. The medium also includes a gas-liquid mixing system (for example, a steam and drainage mixing system), a gas-solid mixing system (for example, conveying pulverized coal by air), a liquid-solid mixing system (for example, slurry), and the like.

[0040] "Equipment parts" refer to, for example, fluid conduction elements and machines used in fluid conveying systems. Examples of fluid conduction elements include piping, telescopic / flexible pipes (bellows, flexible pipes, etc.), bends, elbows, joints, valves (manual valves, electric valves, solenoid valves, regulating valves, safety valves, check valves, etc.). Examples of machines include instruments, conveying machines, filters, reservoirs, steam traps, desuperheaters, etc. Examples of instruments include pressure gauges, thermometers, flow meters, etc. Examples of conveying machines include pumps, fans, blowers, compressors, conveyors, etc. Examples of peripheral components include insulation machines (insulation components), piping support components, machine support frames, steel frames, etc.

[0041] Fig. 20 Represents the relationship between equipment parts.

[0042] There are some equipment parts whose specifications cannot be selected unless the design is done taking into account the flow rate variation range and the operation of the equipment. Examples of such equipment parts include safety valves, control valves (including dry and oil-operated), heat exchangers, desuperheaters, orifices, steam traps and other piping components, and conveying equipment such as pumps, fans, blowers, and compressors.

[0043] In addition, there are equipment components that require electrical connections such as power supply, measurement / control signals, etc. Such equipment components include, for example, solenoid valves, electric valves, control valves (including idle and oil-operated), pumps, fans, blowers, compressors, conveyors and other conveying machines and instruments.

[0044] Hereinafter, a parts purchase support device 1 for supporting the purchase of the above-mentioned equipment parts will be described with reference to the drawings.

[0045] Figure 1 1 is a diagram showing a network structure of the component purchase support device 1 according to the present embodiment. Figure 1As shown, the parts purchase support device 1 is configured to be connectable to the customer terminal 70 and the supplier terminal 80 via a network, and to be able to send and receive information to each other. Examples of the network include Wi-Fi, mobile communication systems (3G, 4G, 5G, 6G, LTE, etc.), wireless LAN (Local Area Network), wired LAN, etc.

[0046] exist Figure 1 In the embodiment, one client terminal 70 and one supplier terminal 80 are illustrated, but the number of client terminals 70 and supplier terminals 80 connected to the parts purchasing support apparatus 1 is not limited to this example.

[0047] exist Figure 1 In the example, the component purchase support device 1, the client terminal 70, and the supplier terminal 80 are connected via the same network, but the present invention is not limited to this example. For example, the network connecting the component purchase support device 1 and the client terminal 70 may be different from the network connecting the component purchase support device 1 and the supplier terminal 80.

[0048] Figure 2 FIG. 1 is a schematic block diagram showing an example of the hardware structure of the parts purchase support device 1. The parts purchase support device 1 is a so-called server (computer). Figure 2 As shown in the example in FIG. 1 , the main structure includes a CPU (processor) 11, an auxiliary storage device 12 for storing programs (for example, a parts purchase assistance program) executed by the CPU 11, a main memory 13 that functions as a work area when executing each program, and a communication device 14 for connecting to a network, and these components are connected via a bus 18. The parts purchase assistance device 1 may also include an input unit 15 such as a keyboard and a display unit 16. The auxiliary storage device 12 stores, for example, an OS for controlling the entire parts purchase assistance device 1, various drivers for performing hardware operations on peripheral devices, applications for implementing the parts purchase assistance device 1, and various data and files. As an example of the auxiliary storage device 12, a semiconductor memory, a magnetic disk, an optical magnetic disk, etc. can be cited.

[0049] The client terminal 70 is an information processing device used by users who wish to purchase equipment parts. The client terminal 70 is, for example, a desktop PC, a notebook PC, a tablet PC, a tablet terminal, a mobile phone terminal, a smart phone, etc. The structure of the client terminal 70 is well known, so a detailed description is omitted, but similar to the above-mentioned component purchase auxiliary device 1, it has: a CPU, an auxiliary storage device, a main memory, a communication device, and an input unit. In addition, the client terminal 70 has a display unit (a liquid crystal display, an organic EL display, etc.). In addition, the client terminal 70 can have a microphone and a speaker. The auxiliary storage device stores, for example, an OS such as Windows (registered trademark), iOS (registered trademark), and Android (registered trademark) for controlling the client terminal 70, various drivers for performing hardware operations on peripheral machines, applications for realizing the functions of the client terminal 70 described later, and various data and files.

[0050] The supplier terminal 80 is an information processing device used by suppliers who sell equipment parts. Here, "supplier" refers to, for example, a company that manufactures and sells equipment parts. In the case where a manufacturing company of equipment parts uses a trading company as an agent to sell its own products, the combination of the manufacturing company of equipment parts and the trading company is called "supplier".

[0051] The supplier terminal 80 is, for example, a desktop PC, a notebook PC, a tablet PC, a tablet terminal, a mobile phone terminal, a smart phone, etc. The structure of the supplier terminal 80 is well known, so a detailed description is omitted, but similar to the above-mentioned component purchase assistance device 1, it has: a CPU, an auxiliary storage device, a main memory, a communication device, and an input unit. In addition, the supplier terminal 80 has a display unit (a liquid crystal display, an organic EL display, etc.). In addition, the supplier terminal 80 may also have a microphone and a speaker. The auxiliary storage device stores, for example, an OS such as Windows (registered trademark), iOS (registered trademark), and Android (registered trademark) for controlling the entire supplier terminal 80, various drivers for performing hardware operations on peripheral machines, applications for realizing the functions of the supplier terminal 80 described later, and various data and files.

[0052] Next, the functions of the parts purchasing support device 1 according to the present embodiment will be described. Figure 31 is a functional structure diagram showing an example of the functions of the parts purchase assistance device 1 of the present embodiment. A series of processes for realizing the functions shown below are stored as a program (for example, a parts purchase assistance program) in the auxiliary storage device 12 of the parts purchase assistance device 1 as an example, and the CPU 11 realizes various functions by reading the program into the main memory 13 and executing it. The program can also be applied in a manner of being pre-installed in the auxiliary storage device 12 of the parts purchase assistance device 1, being provided in a state of being stored in a computer-readable storage medium, being distributed via a wired or wireless communication unit, etc. The computer-readable storage medium refers to a magnetic disk, a magneto-optical disk, a CD-ROM, a DVD-ROM, a semiconductor memory, etc.

[0053] like Figure 3 As shown, the parts purchase support device 1 includes a model number database 21 , a price and delivery date database 22 , a price and delivery date actual performance database 23 , and an option database 24 .

[0054] The model number database 21 stores the model numbers of the equipment parts sold by each supplier in association with their specification data. The model number database 21 may also store a required input item list in association with each supplier by registering each equipment part or each model number with required items required for model selection.

[0055] In the price and delivery date database 22, the delivery date and price of the equipment parts are stored for each supplier. The price and delivery date database 22 is, for example, a database referenced by the estimate making unit 35 described later. The prices and delivery dates stored in the price and delivery date database 22 can be updated by each supplier at any time. Thus, the estimate making unit 35 can use the latest data to make an estimate. Thus, a highly reliable estimate can be provided to the user. In the price, in addition to the price of the equipment parts, various expenses required for the delivery of the goods can also be registered.

[0056] The association of the internal data in the price and delivery date database 22 is not particularly limited. That is, it is sufficient to be configured so that when the model of the equipment component is determined, the information of the supplier, price, and delivery date can be obtained, and the association of the specific internal data is not particularly limited. For example, the price and delivery date database 22 may also independently include a database that associates each equipment component provided by the supplier with its delivery date and a database that associates each equipment component provided by the supplier with its price.

[0057] The price and delivery date performance database 23 stores the performance data of the delivery date and price of each equipment component or each model for each supplier. The price and delivery date performance database 23 is, for example, a database referenced by the component outline selection unit 32 described later. The price and delivery date performance database 23 stores the actual delivery date and price of equipment components sold by each supplier company in the past, which is different from the price and delivery date database 22 in which the supplier can change the information at any time. The price and delivery date performance database 23 may also store the supplier's standard price and standard delivery date for each equipment component or each model.

[0058] The association of the internal data in the price and delivery date performance database 23 is not particularly limited. That is, it is sufficient to be configured so that when the model of the equipment component is determined, the information of the supplier, the price performance data, and the delivery date performance data can be obtained, and the association of the specific internal data is not particularly limited. For example, the price and delivery date performance database 23 can also independently include a database that establishes an association between each equipment component provided by the supplier and the performance data of the delivery date, and a database that establishes an association between each equipment component provided by the supplier and the price performance data.

[0059] The option database 24 stores option information that associates equipment parts with option information for each supplier. Examples of option information include option products (consumables, special tools, etc.), instructor dispatch during installation, operation adjustment during trial operation, technical support services such as troubleshooting, and specification upgrade services (e.g., corrosion-resistant cladding, advanced painting, additional inspection, submission of drawings, etc.). The option database 24 is, for example, a database referenced by the option creation unit 45 described later.

[0060] When the number of registered options exceeds the predetermined number, information on past selection rates (the percentage of additional options selected by users who purchased the equipment component in the past) may be registered in association with each option. Thus, when the option information is presented to the user, the top predetermined number may be selected and acquired in descending order of selection rate, and the acquired option information may be presented to the user.

[0061] Detailed information can be registered in association with various options in the option database 24. For example, detailed information of spare parts may include delivery date, price, replacement period, etc. Detailed information of technical support and optional services may include provision period, price, features, advantages, precautions, etc.

[0062] In this embodiment, the parts purchase support device 1 is described by taking as an example a case where the device includes a model database 21, a price and delivery date database 22, a price and delivery date actual performance database 23, and an option database 24, but the present invention is not limited to this example. For example, part or all of these databases may be stored in other servers connected via a network. In addition, these data may be stored in a dispersed manner in a plurality of servers.

[0063] That is, the data stored in these databases do not need to be stored in the parts purchase support device 1, and it is sufficient as long as the device is configured to be able to acquire such information.

[0064] The component purchase support device 1 includes a condition input support unit 31, a component selection unit 34, and an estimate preparation unit 35 as main components. The component purchase support device 1 may further include a component general selection unit 32, a component selection support unit 33, an order reservation support unit 36, an order support unit 37, and a delivery support unit 38. Each unit will be described in detail below.

[0065] 〔Condition input auxiliary part〕

[0066] The condition input auxiliary unit 31 allows the user to input at least one of the name of the component to be purchased, the type of fluid, the design temperature, the design pressure, the operating temperature, and the operating pressure as an input condition. For example, the condition input auxiliary unit 31 generates screen data for causing the client terminal 70 to display a condition input screen for inputting these condition inputs, and transmits the screen data to the client terminal 70.

[0067] Figure 4 An example of a condition input screen is shown. Figure 4 The illustrated condition input screen includes fields for inputting various conditions such as application standards, delivery dates, required drawings, required inspections, and painting in addition to the above-mentioned conditions.

[0068] In addition, in the condition input screen, you can also set input fields for various information related to delivery, such as the latest allowable delivery date, the maximum allowable price, connection constraints (size, type of connector, etc., including not only the mechanical side but also the electrical side), desired delivery destination, packaging specifications, delivery method, etc.

[0069] The above-mentioned application standard is a standard that the user can select the standard to be applied during design. For example, the user can select various standards such as JIS, ISO, ASME, EN, IEEE, etc. More specifically, individual standards such as the High Pressure Gas Safety Law, the Electric Business Law, and the Pressure Vessel Construction Standard can also be selected. The method of considering the safety factor and the set value varies depending on each standard, so by inputting these conditions, the user can save the effort of confirming whether the standard is met.

[0070] By inputting the latest allowable delivery date and the highest allowable price as conditions, delivery dates and prices that do not meet the user's expectations can be excluded. This can improve user convenience and reduce the computational processing load of the parts purchase support device 1.

[0071] Regarding conditional input, multiple input modes may also be provided. For example, multiple input modes may be presented to the user so that the user may select any one of them. Furthermore, the conditional input auxiliary unit 31 may also generate a conditional input screen corresponding to the input mode selected by the user and send it to the client terminal 70.

[0072] Examples of the input mode include a detailed input mode, a simple input mode, and a model number input mode.

[0073] The detailed input mode is a mode for inputting all conditions required when a supplier selects a part. This mode is intended for users who are proficient in engineering in fluid delivery systems.

[0074] The simple input mode is a mode for inexperienced users to limit input items to main items, for example, a mode in which some conditions among the conditions input in the detailed input mode are omitted.

[0075] The model input mode is a mode for inputting a supplier name or model number. It is independent of the detailed input mode and the simple input mode described above, and is a mode for users who want to purchase the same parts as existing equipment parts, or users who have decided in advance to check the model number of a supplier's catalog, etc.

[0076] In this way, by configuring a plurality of input modes, the user can select a desired input mode, and a service corresponding to the user's engineering ability and needs can be provided.

[0077] 〔Input support section〕

[0078] The condition input support unit 31 may include, for example, an input support unit 41 (see Figure 3 ) The input support unit 41 temporarily inputs the input conditions that have not been input by the user among the plurality of input conditions based on past accumulated data or preset initial values.

[0079] For example, the input auxiliary unit 41 holds initial values ​​related to the design conditions and the operating conditions in advance, and when the input conditions are not input in the design conditions and the operating conditions, the initial values ​​thereof are temporarily input. In addition, representative values ​​based on past actual performance values ​​etc. may be temporarily input instead of the initial values.

[0080] Furthermore, the input support unit 41 may ask questions to the user according to a predetermined question flow, and allow the user to input insufficient input conditions through a dialogue format in which the user answers the questions.

[0081] When a provisional input is performed by the input support unit 41 , the provisional input conditions may be presented to the user to allow the user to confirm whether the conditions deviate from the user's assumptions.

[0082] For example, equipment components not only have constraints such as shape and strength associated with the components themselves, but also have constraints on the fluid flowing inside, so a certain degree of experience is required to select appropriate components. Therefore, inexperienced users do not know what conditions to set and sometimes find it difficult to set conditions independently. In such a case, by providing the input auxiliary unit 41 and assisting the user's input, even users who lack engineering experience in the fluid delivery system can input appropriate conditions required for the arrangement of equipment components.

[0083] In addition, the input support unit 41 may also prompt the application standards. For example, it may determine the laws and standards that need to be applied based on the type of equipment, user registration information (information of the company to which it belongs), the type of fluid, pressure and other conditions, and confirm whether the application is necessary with the user.

[0084] For example, depending on the standard, the setting method or idea may be different. For example, in the safety valve, although there is a standard based on JIS, the setting value and error of the blow-out pressure are different in the electrical business law and the pressure vessel construction standard. Even in such a case, by prompting the application standard through the input auxiliary unit 41, the user can arrange the equipment parts that meet the required standards, and it is possible to suppress selection errors or rework caused by differences in standards.

[0085] 〔Automatic input section〕

[0086] The condition input auxiliary unit 31 may further include an automatic input unit 42. For example, the automatic input unit 42 automatically inputs the input conditions by analyzing the electronic data (e.g., scanned data of design books such as input specifications and specification sheets, photos of nameplates of installed equipment parts, etc.) attached by the user in the condition input screen using AI (Artificial Intelligence).

[0087] The automatic input unit 42 may read condition values ​​such as maximum value, average value, minimum value, etc. from operation data added by the user (for example, a time data list, a trend graph, etc.), and automatically input the read condition values.

[0088] Thus, by providing the automatic input unit 42, the user does not need to perform manual input himself, and the input burden on the user can be reduced.

[0089] 〔Parts Selection〕

[0090] The parts summary selection unit 32 selects equipment parts that meet the input conditions from the model database 21, and further obtains the prices and delivery dates of the selected multiple equipment parts from the price and delivery date performance database 23, selects equipment parts to be presented as candidate parts based on the obtained prices and delivery dates, and transmits information of the selected multiple equipment parts to the client terminal 70. As a result, a parts summary selection screen is displayed on the client terminal 70.

[0091] More specifically, the component outline selection unit 32 first selects the model of the equipment component that meets the design conditions (design temperature, design pressure, operating temperature, operating pressure, etc.) among the various conditions inputted, referring to the model database 21. In addition, for equipment components that require fluid calculation, the component outline selection unit 32 determines the design specifications by performing fluid calculations that meet the application standards (JIS, ASME, etc.) inputted as input conditions and general calculation formulas, and selects the model of the equipment component that meets the determined design specifications from the model database 21.

[0092] In addition, the component summary selection unit 32 obtains the actual price and actual delivery date of the selected model from the price and delivery date actual performance database 23 corresponding to the supplier of the selected model. Instead of the actual price and actual delivery date, a standard price and standard delivery date may be obtained. The price may also include standard packaging fees and transportation fees.

[0093] For example, in the past, in the arrangement of small (small or low) equipment parts, the sales and profits obtained relative to the time of making the estimate were small, so depending on the supplier, sometimes an estimate higher than the standard price or an estimate with a delivery period longer than the standard delivery period was prompted. Therefore, the component summary selection unit 32 is set to display the performance value (for example, the estimated performance price or the accepted order performance price, the estimated performance delivery period or the accepted order performance delivery period). As a result, suppliers who have prompted many high estimates or long delivery periods in the past are difficult to be displayed in the upper position in the display of the price sequence or delivery period sequence described later, so they will miss the user's selection and will not be selected as candidates for ordering. Therefore, it is not good for suppliers to prompt too high prices or slower delivery periods, resulting in users being able to obtain products cheaply and quickly.

[0094] When the model is selected in this way and the actual price and actual delivery date of the selected model are obtained, the parts summary selection unit 32 generates a parts summary selection screen based on the obtained information and transmits the generated screen data to the client terminal 70. Thus, the parts summary selection screen is displayed on the client terminal 70. That is, the models of the plurality of equipment parts selected based on the input conditions are displayed as candidate parts on the parts summary selection screen.

[0095] Figure 5This shows an example of a screen for selecting parts. Figure 5 In the illustrated component summary selection screen, the model numbers of a plurality of equipment components selected based on the input conditions are displayed as candidate components. In addition, the supplier information is added to the model number.

[0096] Here, the number of part models and the number of suppliers presented to the user can be arbitrarily determined. For example, the number of part models is preferably 5 or more, and the number of suppliers is preferably 3 or more.

[0097] In the parts summary selection screen, for example, conditions for selection may also be displayed. In this case, the conditions temporarily input in the condition input auxiliary unit 31 may be displayed in a display mode different from the conditions input by the user. As an example of a different display mode, color distinction, display message, etc. may be cited. In this way, the user can easily identify the conditions temporarily input in the parts purchase auxiliary device 1.

[0098] An input unit BT1 is provided in the component summary selection screen, and the input unit BT1 is used to display a component comparison screen showing the comparison of these candidate components according to predetermined evaluation items. When the user operates (presses or clicks) the input unit BT1, the component summary selection unit 32 sends the information of the component comparison screen to the client terminal 70. As a result, the component comparison screen is displayed on the client terminal 70. Here, the timing of sending the information of the component comparison screen is not particularly limited. For example, the component summary selection unit 32 may also send the information of the component comparison screen together with the information of the component summary selection screen to the client terminal 70.

[0099] Figure 6 An example of the parts comparison screen is shown below. Figure 6 In the illustrated parts comparison screen, the model numbers of five equipment parts are displayed in order for each evaluation item of price, delivery date, evaluation, low energy loss, and conformity. The detailed information of the selected part is displayed on the right side of the screen.

[0100] In the parts comparison screen, products may be displayed in order of price, delivery date, reputation, low energy loss, conformity, recommendation, etc. The screen may be configured so that the user can select any of them.

[0101] The evaluation order is set based on, for example, the word-of-mouth evaluation of the supplier by the user. The word-of-mouth evaluation includes, for example, the average score of the user's evaluation out of 5.0. In addition, it may also include the user's feelings, etc. In addition, it may also be an evaluation that takes into account the transaction performance or the evaluation results of the operator based on the supplier monitoring.

[0102] The low energy loss order is, for example, the order of energy loss caused by the conversion of kinetic energy into frictional heat, etc., from small to large, typically the order of pressure loss values ​​of the internal fluid from small to large. In this case, energy loss data (for example, pressure loss value relative to a specified flow rate, etc.) is registered for each component, and the display order can be determined by reading the energy loss data associated with the selected component and comparing them.

[0103] For example, when the pressure loss increases, the flow rate flowing through the same structure becomes smaller. In order to flow the same flow rate, it is necessary to increase the pipe diameter, enlarge the valve, and other means to increase the flow path. Therefore, there are disadvantages such as increased space constraints and higher initial costs. In addition, by increasing the discharge pressure of the pump, in other words, increasing the motor output, the same flow rate can be made to flow, but in this case, there are also disadvantages such as higher initial costs and higher operating costs. It is expected that the pressure loss will be minimized within a reasonable range, so by presenting the components to the user in order of low energy loss, the components can be studied from the aspects of installation space and initial costs.

[0104] As a method for calculating the pressure loss, the following method can be mentioned.

[0105] (1) Based on the pressure loss value relative to the representative flow rate (provided by the supplier), the sliding calculation is performed with the square of the flow rate.

[0106] (2) Calculate using a formula for pressure loss relative to flow rate. For example, in the case of a valve, calculate using the Cv value, and in the case of a flow meter, calculate using a manually written formula.

[0107] (3) Based on the Reynolds number and the roughness of the inner surface of the tube, the pressure loss coefficient is calculated using the Mooney diagram, and the calculation is performed based on the loss coefficient and flow rate.

[0108] (4) Calculate based on the loss coefficient determined by the flow rate and the type and shape of the equipment components. (This is the calculation of pressure loss in bends, etc. There are many known types of loss coefficients, and you can also choose according to the user's needs)

[0109] The order of conformity is displayed, for example, in descending order of conformity with the required specifications. More specifically, the order is displayed in descending order of the proportion of items in the specification-determining parameters that use user input values. The degree of conformity is calculated, for example, using factors such as the proportion of items that use user input values ​​and their weighted values, and how close the condition of "operating condition + margin (typically about +5%)" is to the maximum operating pressure temperature of the equipment component. This order of conformity is, for example, an effective display method when there are deficiencies in the input conditions.

[0110] The recommended order is, for example, to comprehensively evaluate the price, delivery date, evaluation, low energy loss, compliance, etc., and to display them in order from the highest to the lowest comprehensive evaluation value. For example, it is also possible to substitute the evaluation values ​​of price, delivery date, evaluation, low energy loss, and compliance into a predetermined evaluation value calculation formula, calculate the comprehensive evaluation value for each selected component, and display them in order from high to low according to the calculated comprehensive evaluation values. The evaluation value calculation formula can be set arbitrarily. For example, the evaluation of each item can be evaluated with a full score of 10 points, and the value can be set to the value obtained by adding each item together, or it can be set to the value obtained by adding the value obtained by setting a weight coefficient for each item and multiplying the score of each item by the weight coefficient.

[0111] In addition, machine learning may be performed using the past performance of the operator of the component purchase assistance device 1, past performance of similar designs, or past performance of the operation of the component purchase assistance device 1, and the recommended order may be displayed starting from the device components that are close to the machine learning results.

[0112] On the parts overview selection screen ( Figure 5 ) or the parts comparison screen ( Figure 6 ), the actual price and actual delivery date can also be displayed in association with each model. At this time, the actual price / actual delivery date data can also be displayed with a range. For example, the data of the lowest price~average value~highest value, and the data of the 20% value~80% value obtained by discarding the cheap 20% and the expensive 20% can be displayed. If the user wishes, a histogram can also be displayed.

[0113] Thus, in addition to the above effects, the user can also select the target product for detailed calculation according to the fluctuation range of price and delivery time. As a result, the convenience of the user is improved. In addition, the above displays can also be appropriately combined for display.

[0114] Figure 6 The parts comparison screen shown is an example and is not limited to this. For example, the delivery date can also be displayed in the delivery date order column. In addition, the evaluation score can also be displayed in the evaluation order column. In addition, the energy loss value can also be displayed in the low energy loss order column. In addition, the compliance evaluation value can also be displayed in the compliance order column.

[0115] 〔Parts selection assistance section〕

[0116] The component selection assistance unit 33 generates screen data for causing the client terminal 70 to display a selection assistance screen for assisting the user in selecting a device component.

[0117] For example, when receiving a request to display a selection assistance screen from the client terminal 70, the component selection assistance unit 33 generates a selection assistance screen and transmits it to the client terminal 70. For example, on the component comparison screen (see Figure 6 ) is provided with an input unit BT2 for displaying a selection auxiliary screen for auxiliary component selection.

[0118] When the user selects any one of the candidate components and operates the input unit BT2 , a display request for the selection assistance screen is transmitted to the components purchase assistance apparatus 1 .

[0119] When receiving a request to display the selection assistance screen, the component selection assistance unit 33 determines the supplier of the candidate component selected by the user, searches the model database 21 of the determined supplier, and extracts a model having specifications close to the selected model. In addition, the component selection assistance unit 33 obtains the price and delivery date of each model from the price and delivery date database 22 or the price and delivery date actual performance database 23.

[0120] Next, the component selection support section 33 creates screen data related to a selection support screen that associates characteristic information, prices, delivery dates, operating conditions, and design conditions related to each of the extracted plurality of models, and transmits the screen data to the client terminal 70 .

[0121] Thus, the model and specification of the candidate component selected by the user, specification information of models from the same supplier with similar specifications, price and delivery date information associated with each model, and operating conditions and design conditions are displayed on the selection assistance screen.

[0122] Figure 7 An example of a selection assistance screen is shown. Figure 7 In the example, the parameters specific to the selected component are shown in an orthogonal coordinate system, and the characteristics related to the model selected by the user and at least one model having a specification close to the model are displayed in the orthogonal coordinate system. More specifically, Figure 7 This is a diagram showing an example of a selection assistance screen related to the product "valve", showing the characteristics of four models A to D in an orthogonal coordinate system with pressure on the horizontal axis and temperature on the vertical axis. In addition, operating conditions and design conditions are displayed in the orthogonal coordinate system.

[0123] When at least one of a price and a delivery date is associated with each model, this information may also be displayed on the selection assistance screen.

[0124] Here, the above selection assistance screen is an example and is not limited to this. For example, the orthogonal coordinate system is not limited to two dimensions, but may be multidimensional. For example, axes representing other parameters unique to a component, such as flow rate and pressure loss, may be added. For example, by selecting important parameters for selecting components for each device component in advance, the user can be prompted with information useful in selecting components. In addition, instead of adding parameters related to the characteristics of the component, axes such as price and delivery date may be added.

[0125] In addition, the component selection assistance unit 33 may suggest a recommended model instead of or in addition to the above-mentioned chart.

[0126] Furthermore, in the selection assistance screen, the design conditions may also be configured to be changeable by the user. Figure 7 When the user changes the design conditions in the selection assistance screen shown (in Figure 7 In the case where the design conditions are moved from the coordinates before the selection auxiliary utilization to the coordinates after the selection auxiliary utilization), the component selection auxiliary unit 33 reselects the candidate components that meet the design conditions after the shift, and re-creates the selection auxiliary screen based on the newly selected candidate components. Thus, the user is prompted with the specification information of the candidate components selected based on the changed design conditions and the model of the same supplier whose specifications are close to the candidate components.

[0127] For example, in the initial stage of a project in a fluid delivery system, there is a range of permissible operating conditions and design conditions, and there is often room for change. On the other hand, in the stage of arranging equipment parts, in order to facilitate the selection and implementation by suppliers, and in order to prevent suppliers from selecting products that do not meet user requirements, specific operating conditions and design conditions are often set and prompted to suppliers. In this way, even if there is a range of permissible operating conditions and design conditions, in order to reduce the time required for the arrangement process or rework, the range of conditions has to be intentionally narrowed. Therefore, especially when there is room to choose a more favorable product in terms of price or delivery time, equipment parts are sometimes arranged without noticing this room.

[0128] When the design conditions are near the dividing line of the model, the user is troubled about whether to choose a model with a large margin relative to the design conditions. In this case, for example, when a model with a margin is selected, the specifications have a margin, but on the other hand, it usually becomes high-priced and has a long delivery period. When a model with a small margin is selected, there is a tendency to be cheap and have a short delivery period. On the other hand, the margin of the specifications becomes smaller, and the tolerance to changes in the operating conditions of the equipment may become smaller. In the end, the user makes a comprehensive judgment based on the specifications, price, and delivery period to select the model, but in the usual procurement procedure, the possibility of the design conditions being near the dividing line of the model is clarified from the beginning. In the case of not obtaining the estimates of both the model with a margin and the model with a small margin in advance, generally only the estimate of a certain model is prompted. In this case, it is necessary to re-obtain the estimate of the party that was not prompted, which requires additional working hours and periods. In addition, it is also troublesome for suppliers to issue multiple estimates for comparison. That is, even if estimates for a plurality of parts are prepared and presented for comparison, since the selected part is one of them, the effort and time required for the estimates for the unselected parts will be wasted.

[0129] In view of such a problem, in the present embodiment, the above-mentioned component selection auxiliary unit 33 is provided to present the user with a selection auxiliary screen. Thus, the characteristics, design conditions, and operating conditions of each model can be visually presented to the user. As a result, the user can intuitively recognize to what extent the design conditions must be adjusted to select different models, and can select a model that meets the user's needs.

[0130] In addition, in this embodiment, the user can change the design conditions by a simple operation such as moving the design conditions displayed in the selection auxiliary screen to the desired coordinates, and when the design conditions are changed, the candidate components based on the changed design conditions are selected again. In this way, the candidate components based on the changed design conditions are automatically selected, so the user can set the operating conditions and design conditions as wide as possible without paying attention to the time required for the arrangement of the equipment parts or rework. In addition, the operating conditions and design conditions can be re-evaluated while observing the price and delivery date of each model, and a product that better meets the needs can be selected.

[0131] Figure 7 The selected auxiliary screen shown is an example and can also be displayed in other ways. Figure 8 As shown, the characteristics of each component may be displayed as an area having a certain range.

[0132] 〔Parts Selection Department〕

[0133] The component selection unit 34 (see Figure 3 ) For example, it has a necessary condition determination unit 43.

[0134] The necessary condition determination unit 43 determines whether the input condition satisfies the necessary condition required for selecting the model of the equipment component. Specifically, the necessary condition determination unit 43 obtains a list of necessary input items determined according to the supplier and the equipment component from the model database 21 for each equipment component selected by the user. Next, the necessary condition determination unit 43 compares the obtained list of necessary input items with the input condition input in the condition input screen to determine whether there is insufficient information for performing detailed specification calculation described later.

[0135] As a result, if there is insufficient information, the necessary condition determination unit 43 creates an additional input screen for urging the user to input the insufficient conditions, and transmits it to the client terminal 70. Thus, the additional input screen for the user to perform additional input is displayed on the client terminal 70. Thus, the user can additionally input input conditions related to the insufficient conditions.

[0136] Note that the component selecting section 34 performs detailed calculation of specifications for the device component of the model selected by the user, based on the input conditions input by the user.

[0137] The component selection unit 34 first performs detailed calculations for the equipment component selected by the user as a purchase candidate based on the supplier name and model, using the calculation formula that should be applied to the model of the supplier, and determines whether the equipment component meets the required specifications. In the case where the equipment component meets the required specifications, it is determined to be the equipment component. In the case where the equipment component does not meet the required specifications, a calculation formula that should be applied to a model (similar model) with conditions close to the model is used to perform detailed calculations to determine whether the equipment component of the similar model meets the required specifications. In addition, for example, the supplier can also be asked from the inquiry auxiliary unit 44 described later whether there is an equipment component that meets the required specifications.

[0138] This calculation may be performed by the parts purchasing support device 1 or may be performed in each supplier terminal 80. When each supplier has its own calculation tool, the calculation tool may be used.

[0139] In the parts purchasing support device 1, when selecting equipment parts, different criteria and calculation formulas are selected for each supplier. If calculations for each supplier are to be performed at once, the amount of calculation becomes huge, and it is conceivable that it takes time to study specifications and estimate prices.

[0140] Therefore, in this embodiment, the component rough selection unit 32 performs rough calculation using application standards and general calculation formulas, in other words, calculation formulas that are not dependent on the supplier's predetermined calculation formulas, and in addition, the information of the equipment component selected as a result of the rough calculation is presented to the user together with the rough estimate. Furthermore, the component selection unit 34 performs detailed calculations using the design parameters and calculation formulas selected according to each supplier, etc., for the equipment component selected by the user from the prompted equipment components, and determines whether the equipment component selected by the user is a component that meets the required specifications based on the input conditions. Furthermore, in the case of a component that meets the required specifications, a detailed estimate of the component is prepared and presented to the user together with the component information. Thus, the problem of data processing volume and processing time is solved. In this way, by introducing a two-stage estimate (rough estimate + detailed estimate) structure, a structure based on the result of the rough estimate is adopted to narrow down the suppliers and models that enter the detailed calculation, and the amount of calculation can be suppressed to a minimum while absorbing the needs of the user.

[0141] In the case where the two-stage estimation is not adopted and the estimation is performed in one stage from the beginning, if there is an error or insufficiency in the search conditions or if the user's wishes change, it is necessary to select the equipment parts again from the beginning, which is inefficient. In contrast, as in the present embodiment, by introducing a two-stage estimation structure, the equipment parts selected by the rough specification calculation are presented to the user in the rough estimation step, thereby reducing the amount of processing and improving efficiency.

[0142] The component selection unit 34 (see Figure 3 ) For example, it has an inquiry assistance unit 44.

[0143] The inquiry support unit 44, for example, creates a supplier inquiry screen (not shown) and transmits it to the client terminal 70. The supplier inquiry screen includes, for example, input conditions input by the user, provisional research results, and user information (user's company name, inquiry party, etc.). The supplier inquiry screen is provided with an input unit (for example, an execution button) for requesting an inquiry to the supplier and an input unit (for example, an end button) for inputting that the inquiry is not desired.

[0144] When the user wishes to make an inquiry, he or she operates an inquiry execution button on the supplier inquiry screen displayed on the client terminal 70. As a result, supplier inquiry information is sent to the supplier via the parts purchase support device 1. Upon receiving the inquiry request, the supplier contacts the customer by another phone call or email, and provides the user with information necessary for selecting equipment parts.

[0145] Thus, by providing the inquiry support unit 44 that supports the user in making direct inquiries to the supplier, the user can quickly contact the supplier and obtain the necessary information.

[0146] For example, there may be cases where the equipment engineering is too complicated and it is difficult to select a model on the parts purchase support device 1. In such a case, by providing the inquiry support unit 44, it is possible to obtain cooperation from suppliers and arrange equipment parts that meet the needs of the user. As a result, the range of products that can be arranged starting from the parts purchase support device 1 is increased, and convenience can be improved.

[0147] In addition, it also has the following advantages for suppliers.

[0148] For example, by opening a shop on the parts purchase support device 1, it is possible to have a contact point with a prospective customer. That is, it can be said that a customer who wishes to inquire about a supplier from the supplier inquiry screen has a high purchase intention. Thus, the supplier can increase the possibility of receiving an order by sincerely responding to inquiries from users. In addition, by providing the necessary condition determination unit 43, since the input conditions required for calculating the detailed specifications registered by the supplier have already been input, by providing this information to the supplier, the burden on the supplier side of responding to inquiries can be reduced.

[0149] 〔Estimation Production Department〕

[0150] When the model of the equipment component is selected by the component selection unit 34, the estimate preparation unit 35 re-acquires the specifications of the selected equipment component model and prepares an estimate specification based on the specifications. The estimate specification is a document that records the estimate conditions, in other words, the delivery conditions. The estimate specification does not necessarily need to be presented in the form of a document, and the estimate conditions and delivery conditions may be displayed only on the screen depending on whether the user wishes.

[0151] The estimate generating unit 35 also obtains the price and delivery date of the equipment component from the price and delivery date database 22. In this case, not only the price of the equipment component but also all the prices required for the delivery of the equipment component (for example, packaging fee and transportation fee) may be included.

[0152] In this case, the shortest delivery time and the price associated therewith may be registered in the price and delivery time database 22. The cheapest price and the delivery time associated therewith may also be registered in the price and delivery time database 22. Thus, for example, when the user has enough time to purchase a component, the component can be purchased at a low price corresponding to the delayed delivery time.

[0153] In addition, a diagram or a table associating delivery date with price may be created, and the user may select a preferred combination of delivery date and price. Thus, the user may select an appropriate combination in consideration of both price and delivery date.

[0154] Thus, the estimate preparation unit 35 that generates an estimate specification and an estimate based on the information in the price and delivery date database 22 can reduce the burden on the supplier side required to prepare the estimate, etc. In addition, the supplier can dynamically set the price and delivery date according to the operation status such as the busy period and the idle period by updating the information in the price and delivery date database 22.

[0155] In addition, there are advantages for the user, such as being able to select a plurality of purchase candidates and being able to quickly obtain an estimate.

[0156] Fig. 9 An example of the evaluation result display screen is shown below. Fig. 9 As shown, the estimate result display screen displays the supplier name, supplier evaluation comments, estimate amount, and delivery date for each equipment component. When a plurality of components are displayed on the estimate result display screen, the user selects a component to be ordered.

[0157] The estimate result display screen includes an input unit BT5 for order reservation, an input unit BT6 for displaying estimate specifications, and an input unit BT7 for option selection for each equipment component. When the input unit BT7 is operated on the estimate result display screen, an option screen described later is displayed on the client terminal 70.

[0158] [Option generation section]

[0159] The estimate preparation unit 35 may also include an option preparation unit 45. For example, when the user operates the input unit BT7 for displaying the option screen on the estimate result display screen, the option preparation unit 45 obtains option information associated with the equipment component selected by the user from the option database 24, generates screen data of the option screen for presenting the obtained option information to the user, and transmits the screen data to the client terminal 70.

[0160] As an example of optional information, there may be optional products (consumables, special tools, etc.), dispatch of instructors during installation, operation adjustments during trial runs, technical support services such as troubleshooting, and specification upgrade services (for example, corrosion-resistant cladding, advanced painting, additional inspections, additional submission drawings, etc.).

[0161] When the number of registered options is large and it is difficult to prompt all of them to the user, information on past selection rates (the proportion of additional users who have purchased the device component in the past who selected the option) can be pre-registered in association with each option, and the upper reserved number can be selected in descending order of selection rate to prompt the user.

[0162] Fig.10 An example of the options screen is shown. Fig.10In the selection screen shown, you can select spare parts, anti-corrosion processing, and technical support. In addition, detailed information about each option is displayed at the bottom of each option item.

[0163] By presenting the optional information to the user, the user can purchase spare parts at the same time, which improves the convenience of the user. In addition, by presenting the information that the user may have forgotten to select, such as painting, inspection, and submission of drawings, as optional information, the user can be less likely to forget to order.

[0164] In addition, by providing users with spare parts and various services, suppliers can also increase their chances of receiving orders and expect an increase in sales.

[0165] The option creation unit 45 may also obtain detailed information associated with various options from the option database 24 and transmit the detailed information to the client terminal 70. For example, the detailed information of the spare parts may include the delivery date, price, replacement period, etc. The detailed information of the technical support and option services may include the provision period, price, features, advantages, precautions, etc.

[0166] Thus, the user can purchase the required optional items after understanding the necessity by presenting the detailed information to the user through the option creation unit 45. The supplier can arouse the user's interest by displaying the detailed information (e.g., features, advantages, etc.) in association with each option, and can expect to increase the possibility of receiving an order.

[0167] When the user selects an option on the option screen, the estimate preparation unit 35 modifies the estimate specifications and the estimate based on the information of the selected option, and sends the modified estimate specifications and the estimate to the client terminal 70. Thus, each time the user selects an option, the information is quickly reflected in the estimate specifications and the estimate displayed on the client terminal 70.

[0168] [Order Reservation Assistance Department]

[0169] When an order reservation for a device component is requested from the client terminal 70, the order reservation assisting unit 36 ​​transmits information related to the order reservation to the supplier terminal 80. Examples of the information related to the order reservation include the date and time of the order reservation, the scheduled period for formal ordering, the model of the device component, and user information.

[0170] When receiving the information on the order reservation, the supplier terminal 80 secures the equipment parts based on the information on the order reservation, and prepares to quickly arrange the equipment parts when the user places a formal order.

[0171] At this time, the supplier side can also, for example, maintain a certain period (e.g., one week, which can be determined by each supplier for each product) as the validity period of the estimate and provide the estimate specifications and the estimate price after the order is placed. In addition, a service can be provided to ensure inventory and production capacity in advance for a certain period (e.g., several hours) and agree on the delivery date provided.

[0172] Furthermore, the supplier may also carefully check the order reservation information and the deadline of the company's resources, and can present information such as the delivery date to the user through the parts purchase support device 1.

[0173] Thus, by providing the order reservation support unit 36, it is possible to ensure that the estimated price and delivery date are maintained for a certain period of time. Thus, for example, in the case where there is an approval process in the organization to which the user belongs, even if a certain degree of time is required to place a formal order due to reasons such as adjustments within the company, it is possible to purchase equipment parts under the conditions when the order reservation is made. As a result, the convenience of the user is improved. Moreover, on the supplier side, it is also possible to pay attention to the user's order through the component purchase support device 1 based on the scheduled period of formal ordering and the estimated validity period managed in the component purchase support device 1, so it is possible to expect to increase the possibility of accepting the order.

[0174] 〔Order Support Department〕

[0175] When a formal order for a reserved equipment component is requested from the client terminal 70, the order support unit 37 transmits information related to the order to the supplier terminal 80 of the reserved equipment component.

[0176] [Negotiation Support Department]

[0177] The order support unit 37 may include a negotiation support unit 46 for supporting the negotiation between the user and the supplier of the equipment parts in relation to the order of the equipment parts. The negotiation support unit 46 supports the negotiation between the user and the supplier on the price and the delivery date.

[0178] At this time, in order to protect the supplier from excessive demands from the user, it is preferable to set negotiable conditions in advance. As negotiable conditions, for example, a minimum order quantity and a minimum purchase price can be cited. In addition, an upper limit on the number of negotiations within a certain period of time per user can also be set. In addition, in this case, if the order is finally placed, the negotiations related to the order may not be counted.

[0179] In addition, when predetermined discount conditions are met (for example, when the number of arranged parts exceeds a predetermined number, etc.), the price may be automatically reduced by a certain amount (for example, α% of the total amount).

[0180] By setting negotiable conditions in this way, it is possible to reduce excessive burdens on the supplier side.

[0181] In this way, by providing the negotiation support section 46, even when arranging equipment parts through the parts purchase support device 1, it is possible to negotiate with the supplier side on price or delivery date in the same manner as in the normal purchase process, which can improve the convenience of the user. Depending on the enterprise, there are enterprises where one of the functions of the purchasing department is to negotiate on price or delivery date, and the purchasing department requires the result of price reduction, and negotiations must be conducted with the purchasing department. Even such enterprises can be obtained as customers of the parts purchase support device 1 by providing the negotiation support section 46.

[0182] 〔Delivery Support Department〕

[0183] The delivery assistance unit 38 assists in the delivery procedures of the officially ordered equipment parts. For example, the delivery assistance unit 38 assists in the reception and adjustment of the equipment parts sent to the user. Specifically, the delivery assistance unit obtains delivery information such as the scheduled delivery time, packaging posture, weight, number of trucks, delivery order data, driver information, contact information, transportation company, and vehicle number information from the supplier terminal 80, and sends the obtained delivery information to the customer terminal 70.

[0184] Since driver information, contact information, vehicle number information, etc. are sometimes not available until the day of delivery, the above information can also be provided to the user in sequence from the determined information. In addition, the user can inquire the supplier via the delivery auxiliary unit 38 if there are insufficient items or inquiries.

[0185] Thus, by providing the delivery support unit 38, it is possible to eliminate the need for each adjustment related to delivery, which has been a burden for both the user and the supplier in the past.

[0186] In addition, since information related to the packaging posture can be provided to the user in advance, the user can make advance adjustments such as reception preparation. This is particularly effective when a crane or forklift is required for receiving a large or heavy equipment component. In addition, in the past, communication was conducted by telephone, email, etc., but the information is managed uniformly in the component purchase support device 1, so the management burden of the user can be reduced.

[0187] This can improve user convenience.

[0188] It is also possible to assist the user in managing the delivered goods by attaching an information identification label or a barcode to the delivered goods from the supplier. In addition, the identification information may be managed in the parts purchase support device 1.

[0189] For example, when placing an order for multiple equipment parts at once, the parts are sometimes delivered from different suppliers. In this case, it is not uncommon for the products to be delivered from different suppliers on different delivery dates. The delivered products are placed in a temporary storage location, but considering the subsequent transportation, users often store the products in a packaged state until all the parts arrive, making it difficult to identify the parts from the appearance. In addition, when users place an order for multiple equipment parts at once, they are arranged as a set, so awareness of the individual parts is weak, and it is conceivable that there are problems such as not knowing the purpose of the delivered parts and difficulty in managing the parts.

[0190] In such a case, as described above, by attaching a label for identifying each delivered item to the delivered item and reading the label, information such as the name, purpose, and specifications (weight, size) of the component can be acquired, thereby easily and quickly obtaining information on the delivered item.

[0191] The component purchase assistance device 1 can visually prompt the user of the purpose and characteristics of the component at hand by causing the client terminal 70 to display a screen that emphasizes the component in the list of arranged items, assembly diagram or three-dimensional diagram of the complete system provided to the user, so that the component can be easily identified. Moreover, this information can also be used to assist the user in assembly. In addition to the display of the above-mentioned assembly diagram or three-dimensional diagram, the weight and center of gravity are also displayed, and by displaying the precautions during assembly, it helps to smoothly perform the user's assembly work. In particular, by purchasing a complete system from the component purchase assistance device 1, the component purchase assistance device 1 manages the information required for assembly, so that the above-mentioned service can be provided.

[0192] Next, refer to Figure 11~Figure 17 The following series of processes are stored as a program (eg, a parts purchase support program) in the auxiliary storage device 12 of the parts purchase support device 1, and are implemented by the CPU 11 reading the program into the main memory 13 and executing it.

[0193] Fig.11 FIG. 1 is a flowchart showing an example of the processing steps of the parts purchase support method according to the present embodiment. Fig.11 As shown, the parts purchase assistance method is performed in the order of, for example, a condition input assistance process (SA1), a parts outline selection process (SA2), a parts selection process (SA3), an estimate preparation process (SA4), an order reservation assistance process (SA5), an order assistance process (SA6), and a delivery assistance process (SA7). Each process is described in detail below.

[0194] 〔SA1: Conditional input auxiliary process〕

[0195] Fig.12FIG. 1 is a flowchart showing an example of the processing steps of the condition input auxiliary process of this embodiment. Fig.12 As shown, the parts purchase support device 1 first generates a condition input screen, and sends the screen data of the generated condition input screen to the client terminal 70 (SB1). Figure 4 The condition input screen (SB2) is shown as an example.

[0196] At this time, the information of the equipment parts that the user wants to buy can be obtained first, and the input conditions can be different according to the equipment parts obtained. For example, the format of the condition input screen can be registered according to each equipment part, and the condition input screen corresponding to the equipment part can be sent to the client terminal 70.

[0197] For example, when purchasing a safety valve, you can also input the nominal diameter, type of fluid, set pressure, set pressure management value (error setting), fluid temperature, maximum operating pressure, inlet connection method, material, required blowout volume, blow-off pressure, etc. as conditions. In addition, since the set pressure management value varies depending on the application standard, the application standard can also be included in the input conditions.

[0198] In the condition input screen, the user inputs the condition and the condition is sent. Thus, the input condition input by the user is sent to the component purchase support device 1 (SB3). In the condition input support process, the input support unit 41 can assist the user in inputting and the automatic input unit 42 can automatically input the condition as needed.

[0199] In this way, when the condition input auxiliary step is completed, the next step is to move to the component outline selection step.

[0200] [SA2: Component outline selection process]

[0201] Fig.13 This is a flowchart showing an example of the processing procedure of the component outline selection step according to the present embodiment.

[0202] like Fig.13 As shown, when the component purchasing assistance device 1 accepts the above-mentioned input conditions, it determines the design specifications (SC1) by performing calculations in accordance with the application standards (JIS, ASME, etc.) input as input conditions, and selects the model of the equipment component that meets the determined design specifications from the model database 21 of multiple suppliers (SC2).

[0203] For example, in the case of a safety valve for steam, the supplier selects a candidate model based on information such as the nominal diameter, fluid temperature, and maximum operating pressure input as input conditions. Next, the nominal blowout volume is calculated using the blowout volume determination pressure determined by the set pressure and the application standard (JIS if no input), the constant determined by the fluid conditions during blowout (mainly affected by temperature, pressure, etc.) (representative value if no number is input), the nominal degraded blowout coefficient corresponding to the model of the equipment component (a general value is recorded in JIS B8210, and this value is used), and the blowout area (the blowout area is roughly determined by the nominal diameter. For example, a general value corresponding to the nominal diameter can be used). The calculated nominal blowout volume is compared with the required blowout volume. If the nominal blowout volume is greater than the required blowout volume, it is considered that the required specifications are met and the equipment component is selected as a component candidate. In the case where the nominal blowout volume is less than the required blowout volume, the equipment component is excluded from the component candidate.

[0204] Next, the parts purchase support device 1 obtains the actual price and actual delivery date of the selected model from the price and delivery date performance database 23 corresponding to the supplier of the selected model (SC3), and generates a parts summary selection screen and a parts comparison screen based on the obtained information, and sends the generated screen data to the client terminal 70 (SC4). At this time, if the number of selected part candidates is greater than the predetermined number, the candidate parts may be selected in such a way that the number of equipment parts presented as part candidates becomes less than the predetermined number, taking into account the price or delivery date, etc.

[0205] The client terminal 70 displays a component overview selection screen (SC5). Figure 5 As shown in the example, the model numbers of a plurality of equipment parts selected based on the input conditions are displayed as candidate parts. In the part summary selection screen, when the user operates the input unit BT1 for displaying the part comparison screen, the display Figure 6 The parts comparison screen is shown.

[0206] In the parts comparison screen (refer to Figure 6 ) in the case where the input unit BT2 for requesting the display of the selected auxiliary screen is operated, the parts purchasing assistance device 1 generates Figure 7 The component selection assistance screen shown in FIG. 1 is displayed and sent to the client terminal 70. When the user wishes to change the current input (including temporary input) condition and operates the change button BT3 for requesting to change the input condition, the component purchase assistance device 1 returns to step SB1 (refer to FIG. 1 ). Fig.12 ), generate a condition input screen and send it to the client terminal 70.

[0207] On the parts overview selection screen (see Figure 5 ) and operate the Send button BT8, or in the Parts Comparison screen (see Figure 6 ) and the target component determination button BT4 for determining the target component is operated (SC6), the selected model information is sent to the component purchase support device 1. In this way, when the component purchase support device 1 receives the model information of the target component selected by the user, it ends the component rough selection process and moves to the component selection process.

[0208] [SA3: Parts selection process]

[0209] Fig.14 This is a flowchart showing an example of a processing procedure of a component selection step according to the present embodiment.

[0210] like Fig.14 As shown, when the part purchase support device 1 receives the model information of the target part, it obtains a list of required input items determined according to the supplier and the equipment part for each equipment part selected by the user from the model database 21. Next, the obtained list of required input items is compared with the input conditions entered in the condition input screen to determine whether there is insufficient information for subsequent detailed specification calculation (SD1).

[0211] If there is no shortage information (SD2: Yes), the process proceeds to step SD6. On the other hand, if there is shortage information (SD2: No), the parts purchasing support device 1 creates an additional input screen for prompting the user to input shortage conditions and transmits it to the client terminal 70 (SD3).

[0212] As a result, an additional input screen for the user to perform additional input is displayed on the client terminal 70 (SD4). When the user inputs additional conditions, the additional conditions are transmitted to the parts purchase support device 1 (SD5).

[0213] When the conditions required for detailed calculation are met, the component purchase support device 1 performs detailed specification calculation based on the input conditions (SD6). Specifically, for each equipment component selected by the user, detailed specification calculation is performed using the parameters and calculation formula selected by the supplier.

[0214] For example, in the case of a safety valve for steam, the nominal blowout volume is calculated using the blowout volume determining pressure determined by the set pressure and the application standard, the constant determined by the conditions of the fluid during blowout (mainly affected by temperature, pressure, etc.), the nominal rated blowout coefficient inherent to the equipment component, and the blowout area. Here, the nominal derated blowout coefficient inherent to the equipment component is a value inherently possessed by the supplier of the equipment component as a test value.

[0215] In this way, when the detailed specification calculation is performed, it is determined whether the specification obtained as a result of the calculation satisfies the required specification (SD7). As a result, if the required specification is satisfied, it is determined that the model can be selected (SD7: Yes), and the process proceeds to step SD12. On the other hand, if the required specification is not satisfied, the detailed specification calculation is performed for the similar models set for each model. The detailed specification calculation is repeated until the similar model that becomes a candidate satisfies the required specification, or until it is determined that all similar models do not satisfy the required specification. Furthermore, if it is determined that any similar model satisfies the required specification, the process proceeds to step SD12, and if it is determined that all similar models do not satisfy the required specification, it is determined that the model cannot be selected (SD7: No), and the process proceeds to step SD8.

[0216] For example, in the case of the safety valve for steam described above, the nominal blowout amount calculated using the nominal degraded blowout coefficient that is different for each supplier and the blowout area that is different for each supplier and model is compared with the required blowout amount. That is, in the detailed specification calculation, unlike the case of the rough specification calculation, a more accurate nominal blowout amount is calculated by using the inherent values ​​of the supplier as the nominal rated blowout coefficient and the blowout area. As a result, when the nominal blowout amount is greater than the required blowout amount, it is determined that the required specifications are met and the model can be selected. On the other hand, when the nominal blowout amount is less than the required blowout amount, it is determined that the required specifications are not met, and the determination is transferred to similar models as described above.

[0217] In step SD8, a supplier inquiry screen is generated and transmitted to the client terminal 70. As a result, the supplier inquiry screen is displayed on the client terminal 70 (SD9).

[0218] When the user wishes to inquire the supplier, the user inputs the information and performs a sending operation. Thus, the information that the user wishes to inquire the supplier is sent to the parts purchasing support device 1 (SD10). The parts purchasing support device 1 notifies the supplier terminal 80 of the intention to inquire the supplier (SD11). When the supplier receives the inquiry request, the supplier contacts the customer by another phone call or email, and provides the user with the information required for selecting the equipment parts. Thus, the user can quickly contact the supplier and obtain the required information.

[0219] In this way, when the model of the equipment component that meets the required specifications is selected (SD12), the process moves to the estimation production process as the next process.

[0220] [SA4: Estimation production process]

[0221] Fig.15 This is a flowchart showing an example of the processing procedure of the estimate preparation process according to the present embodiment.

[0222] like Fig.15 As shown, when the model of the equipment component is selected, the parts purchasing support device 1 re-acquires the specifications of the equipment component of the selected model (SE1), and further acquires the price and delivery date of the equipment component from the price and delivery date database 22 (SE2). Then, the obtained information is used to generate an estimate specification and an estimate (SE3). Specifically, screen data for displaying the estimate specification and the estimate is generated.

[0223] Next, the parts purchasing support device 1 obtains option information associated with the equipment parts from the option database 24 (SE4), and generates screen data of the option screen using the obtained option information (SE5). Furthermore, the screen data for displaying the generated estimate specification, estimate, and option information is transmitted to the client terminal 70 (SE6).

[0224] As a result, the client terminal 70 displays an estimate result display screen for displaying an estimate specification sheet and the like (see Fig. 9 )(SE7). In the estimation result display screen, when the user selects an order target component from a plurality of candidate components and further operates the input unit BT7 for displaying the option screen, the option screen (see Fig.10 ). When one or more options related to the order object parts are selected in the option screen and the send button is operated, the information of the selected order object parts and the option information are sent to the parts purchase assistance device 1 (SE8). When the parts purchase assistance device 1 receives the selected option information, it updates the estimate specification and the estimate based on the option information, and sends the updated estimate specification to the client terminal 70 (SE9). The parts purchase assistance device 1 performs the above-mentioned processing each time the user selects option information, and displays the estimate result display screen reflecting the latest option information on the client terminal 70 (refer to Fig. 9 ).

[0225] Next, the user confirms the latest estimate specifications, estimate, and option information, and when the user operates the input unit (order reservation button) BT5 in the estimate result display screen, order reservation information for the equipment parts is sent from the client terminal 70 to the parts purchasing support device 1 (SE10).

[0226] When receiving the order reservation information, the parts purchasing support device 1 moves to the order reservation support step as the next step.

[0227] [SA5: Order reservation auxiliary process]

[0228] Fig.16 This is a flowchart showing an example of the processing procedure of the order reservation supporting process according to the present embodiment.

[0229] When the component purchase assistance device 1 receives the order reservation information, it records the received order reservation information (SF1), and then sends the order reservation information to the supplier terminal 80 (SF2). When the supplier terminal 80 receives the order reservation information, it ensures the production capacity of the equipment parts (SF3). Next, when the person in charge of the supplier enters the formal order deadline and performs the sending operation, the information of the formal order deadline is sent to the component purchase assistance device 1 (SF4). When the component purchase assistance device 1 receives the information of the formal order deadline, it generates an order reservation screen (SF5) notifying the formal order deadline and sends it to the customer terminal 70 (SF6). As a result, the component purchase assistance device 1 moves to the order assistance process as the next process.

[0230] Fig.18 FIG. 1 is a diagram showing an example of an order reservation screen. Fig.18 As shown in FIG. 1 , an order deadline is displayed for each selected component (product 1, product 2) for which an order reservation has been made. Fig.18 In the table, as the order period, a delivery guarantee period and a price guarantee period are displayed.

[0231] In the above-mentioned order reservation auxiliary process, the processing of ensuring production capacity (SF3) can also be omitted. Regardless of whether the production capacity is ensured, in the client terminal 70, for the equipment parts for which the order reservation is accepted, an order reservation screen showing the standard formal order deadline for complying with the delivery date and price (the delivery date is typically the same day, and the price is typically within 1 month, which is predetermined by the supplier) is displayed. In this case, for example, especially for products that the supplier determines to have a high probability of accepting orders, the person in charge of the supplier can also check the order deadline in detail on the basis of ensuring production capacity, reset the formal order deadline for complying with the delivery date and price, contact the user and pay attention to accepting the order.

[0232] The supplier can also mine products that have exceeded the order deadline without being formally ordered under the order reservation status and propose them to the user again. Products that have been accepted for order reservation, in other words, products that have been put into the shopping cart, are products that the user intends to buy, so it is believed that the probability of accepting the order is high. Therefore, as a supplier, it is also worthwhile to free up manpower to pay attention to it.

[0233] 〔SA6: Ordering auxiliary processes〕

[0234] Fig.17 This is a flowchart showing an example of the processing procedure of the order support process according to the present embodiment.

[0235] If the user wishes to negotiate with the supplier before formally placing an order after confirming the estimate, the user performs a negotiation request operation from the client terminal 70. Thus, the negotiation request is transmitted to the parts purchasing support device 1 (SG1).

[0236] When receiving a negotiation request, the component purchase assistance device 1 generates a negotiation assistance screen and sends it to the client terminal 70 (SG2). As a result, the negotiation assistance screen is displayed on the client terminal 70 (SG3). The user inputs the negotiation content and performs a sending operation. As a result, the negotiation content is sent from the client terminal 70 to the component purchase assistance device 1 (SG4). The component purchase assistance device 1 sends the negotiation content to the supplier terminal 80 (SG5). The person in charge of the supplier studies the negotiation content, inputs answers related to the estimated price and estimated delivery date, and performs a sending operation. As a result, the negotiation answer is sent to the component purchase assistance device 1 (SG6).

[0237] When receiving the negotiation response, the parts purchasing support device 1 modifies the estimate specification and the estimate based on the response, and transmits the modified estimate specification and the estimate to the client terminal 70 (SG7).

[0238] Thus, the estimate specification and the estimate reflecting the negotiation result are displayed on the client terminal 70. The negotiation dialogue between the user and the supplier can be repeated multiple times. If the negotiation fails, the parts purchase support device 1 does not modify the estimate specification or the like.

[0239] The user confirms the revised estimate specifications and estimate, and if there is no problem, performs the formal ordering operation. Thus, the formal ordering information is sent to the component purchase support device 1 (SG8). The component purchase support device 1 sends the formal ordering information to the supplier terminal 80 (SG9). Thus, the ordering information reaches the supplier side and moves to the delivery support process as the next process.

[0240] [SA7: Delivery auxiliary process]

[0241] In the delivery support process, the parts purchase support device 1 supports the delivery of the officially ordered equipment parts. When receiving a user's inquiry about delivery, the parts purchase support device 1 sends inquiry information to the supplier terminal 80, thereby supporting the dialogue between the user and the supplier regarding delivery.

[0242] As described above, according to the parts purchase support device 1, the parts purchase support method, and the parts purchase support program of the present embodiment, the user inputs at least one of the name of the part to be purchased, the type of fluid, the design temperature, the design pressure, the operating temperature, and the operating pressure as an input condition, and selects equipment parts that meet the input condition with reference to the model database 21, and displays all or part of the selected plurality of equipment parts as candidate parts on the client terminal 70. In addition, the price and delivery date of the candidate part selected by the user are obtained from the price and delivery date database 22, and the obtained price and delivery date are displayed on the client terminal 70.

[0243] Thus, the user only needs to perform a simple operation such as inputting the input conditions to automatically select the equipment parts that meet the input conditions, and all or part of them are prompted as candidate parts. Thus, the user can select the desired candidate parts from these candidate parts. In addition, the price and delivery date are also prompted for each candidate part, so the desired equipment parts can be easily arranged comprehensively considering the price and delivery date. Thus, the period from condition input to delivery of equipment parts can be effectively shortened.

[0244] Fig.19 This is a diagram showing a comparison between an example of a conventional timetable from condition input to ordering of equipment parts and a timetable from condition input to ordering when arranging equipment parts using the parts purchase support device 1 of this embodiment. Fig.19 As shown, conventionally, it takes about a week or more from (1) deciding on the general specifications to (2) confirming the specifications of similar performance of equipment parts purchased in the past, (3) preparing the purchase specifications, and (4) requesting an estimate. For example, in the case of a safety valve, it is necessary to prepare a purchase specification based on the specifications of the mounting part (e.g., the pressure vessel manifold) and the required specifications of the safety valve, and it takes time to study before requesting an estimate.

[0245] In addition, after entrusting a supplier with an estimate, the supplier will also have to perform tasks such as (5) selecting products according to the purchase specifications, studying specifications, and preparing estimates. Therefore, it sometimes takes about one to four weeks before receiving an estimate response. Even if an estimate response is received, it is necessary to (6) confirm specifications and feedback on plans, (7) adjust delivery dates, and then (8) place an order. Ultimately, it sometimes takes about six to eight weeks from deciding on the general specifications to placing an order. This is typically due to the supplier's estimate manager handling multiple cases in parallel, resulting in a queue, and also because the focus is on responding to inquiries for cases with higher probability, which prevents the work from proceeding smoothly.

[0246] In contrast, according to the component purchase assistance device 1 of the present embodiment, if the conditions are input, the model of the equipment component that is suitable for the design conditions, etc. is automatically prompted as a component candidate. In addition, since all the information required for ordering, such as the specification data, delivery date, price, etc. of the component candidate can be confirmed, the period from the input of the conditions to the ordering is about one week. Thus, compared with the past, for example, the period can be shortened by about seven weeks. The component purchase assistance device 1 minimizes the waiting time generated when people intervene (for example, business activities between users and suppliers, business activities between the salesperson of the supplier and the technical staff of the supplier, business activities between the trading company and the supplier in the case of going through a trading company, etc.), thereby achieving the above-mentioned effect.

[0247] The present disclosure is described above using the embodiments, but the technical scope of the present disclosure is not limited to the scope described in the above embodiments. Various changes or improvements can be applied to the above embodiments without departing from the scope of the disclosure, and the methods to which the changes or improvements are applied are also included in the technical scope of the present disclosure. In addition, the above embodiments can also be appropriately combined.

[0248] Furthermore, the processing flow described in the above embodiment is only an example, and unnecessary steps may be deleted, new steps may be added, or the processing order may be changed without departing from the gist of the present disclosure.

[0249] For example, about Fig.11 The series of processes shown need not be executed in their entirety, and a portion of the processes may be omitted. For example, the component rough selection step may be omitted, and the selection of components in the component selection step may be performed based on the input conditions input in the condition input auxiliary step.

[0250] The parts purchase support device 1 , the parts purchase support method, and the parts purchase support program described above in one embodiment can be understood, for example, as follows.

[0251] The first scheme of the present invention is a component purchase assistance device (1) for assisting the purchase of equipment components. The component purchase assistance device (1) comprises: a condition input assistance unit (31) for allowing a user to input at least one of the name of a component to be purchased, the type of fluid, the design temperature, the design pressure, the operating temperature and the operating pressure as input conditions; a component selection unit (34) for selecting equipment components that meet the above input conditions from a model database (21) in which the models of equipment components are associated with specification data, and causing all or part of the selected multiple equipment components to be displayed as candidate components on a client terminal; and an estimate preparation unit (35) for obtaining the price and delivery date of the candidate component selected by the user from a price and delivery date database (22) in which the delivery dates and prices of equipment components are registered, for each supplier, and causing the obtained price and delivery date to be displayed on a client terminal (70).

[0252] According to the component purchase auxiliary device (1) of the above scheme, the user only needs to perform a simple operation such as inputting input conditions to automatically select equipment components that meet the input conditions, and all or part of them are prompted as candidate components. As a result, the user can select the desired candidate components from these candidate components. In addition, the price and delivery date are also prompted for each candidate component, so that the desired equipment components can be easily arranged comprehensively considering the price and delivery date. In addition, the period from the input of conditions to the delivery of equipment components can be effectively shortened.

[0253] The second scheme of the component purchase assistance device (1) disclosed in the present invention may be based on the first scheme, and the condition input assistance unit may include an input assistance unit (41), and the input assistance unit (41) temporarily inputs the input conditions that have not been input by the user among the plurality of input conditions based on past accumulated data or pre-set initial values.

[0254] According to the component purchase support device (1) of the above scheme, the burden on the user involved in condition input can be reduced and the convenience of the user can be improved.

[0255] The third scheme of the component purchase assistance device (1) of the present disclosure may be based on the first scheme or the second scheme, and the component purchase assistance device (1) may also include a component outline selection unit (32), wherein the component outline selection unit (32) selects equipment components that meet the input conditions from the model database, obtains the prices and delivery dates of the selected multiple equipment components from a price and delivery date actual database in which the past actual values ​​of the delivery dates and prices of the equipment components are registered for each supplier, selects the equipment components that are suggested as candidate components based on the obtained prices and delivery dates, and sends the information of the selected multiple equipment components to the client terminal.

[0256] According to the component purchase support device (1) of the above scheme, candidate components to be presented to the user are selected based on the actual performance value (e.g., the estimated actual performance price or the received order performance price, the estimated actual delivery date or the received order performance delivery date). Thus, information on equipment components that are excellent in terms of price and delivery date can be presented to the user from among the plurality of component quantities registered in the component purchase support device.

[0257] The component purchasing assistance device (1) of the fourth scheme of the present disclosure may be, based on the third scheme, that the component outline selection unit (32) uses a predetermined calculation formula that is not dependent on the supplier of the device component to select the device component that meets the input conditions, and the component selection unit (34) uses a calculation formula set by the supplier of the device component to determine whether each of the device components selected by the user from among the device components selected by the component outline selection unit meets the input conditions, thereby selecting the device component.

[0258] For example, when selecting equipment parts, the selection criteria and calculation formulas differ for each supplier. If calculations for each supplier are to be performed at once, the amount of calculation becomes enormous, and specification research and estimation may take time.

[0259] According to the component purchase support device (1) of the above scheme, the component general selection unit performs a general calculation using a predetermined calculation formula (e.g., an application standard or a general calculation formula) that is not dependent on a supplier, and selects a device component that meets the input conditions. Then, the component selection unit performs a detailed calculation on the device component selected by the user among the device components selected by the component general selection unit. Specifically, the calculation formula set by the supplier of the device component selected by the user is used to determine whether the device component meets the required specifications based on the input conditions, and the component is selected based on the determination result.

[0260] In this way, based on the results of the rough calculation, the number of equipment components involved in the detailed calculation can be reduced, so the amount of calculation can be suppressed to a minimum while taking into account the needs of the user. This can shorten the processing time and improve the convenience of the user.

[0261] The component purchasing assistance device (1) of the fifth scheme of the present invention can be based on the third scheme or the fourth scheme, and the component outline selection unit can send the information of the above-mentioned equipment components to the above-mentioned customer terminal in a manner that displays the plurality of the above-mentioned candidate components in the order of price, delivery date, low energy loss, conformity of input conditions with specifications of equipment components, word-of-mouth evaluation, and comprehensive evaluation.

[0262] According to the above-mentioned component purchase support device (1), excellent equipment components can be presented respectively with respect to important indicators in arranging equipment components, thereby improving the user's purchase intention and providing various information that can be used as a reference when selecting components.

[0263] The component purchase assistance device (1) of the sixth scheme of the present disclosure can be based on any one of the above-mentioned first to fifth schemes, and can also be that the above-mentioned component purchase assistance device (1) has a component selection assistance unit (33), and the above-mentioned component selection assistance unit (33) assists the user in selecting equipment components. The component selection assistance unit obtains specification data of models of the same supplier whose specifications are close to the model of one of the above-mentioned candidate components from the above-mentioned model database, and sends the selection assistance information including price and delivery date information associated with each of the above-mentioned models and operating conditions and design conditions to the above-mentioned customer terminal.

[0264] According to the component purchase support device (1) of the above scheme, the characteristics, design conditions and operating conditions of each model can be presented to the user. As a result, the user can study to what extent the design conditions can be adjusted to select different models, and can select a model that meets the user's needs. In addition, the user can re-evaluate the operating conditions or design conditions while observing the price and delivery time of each model, and select a product that better meets the needs.

[0265] The seventh scheme of the component purchase assistance device (1) disclosed in the present invention is based on the sixth scheme, and the above-mentioned selected auxiliary information is, for example, a characteristic based on the specification of each of the above-mentioned models is depicted in association with each model in an orthogonal coordinate system with predetermined parameters as axes, and information on the above-mentioned operating conditions and the above-mentioned design conditions is depicted in the above-mentioned orthogonal coordinate system.

[0266] According to the component purchase support device (1) of the above scheme, the characteristics, design conditions and operating conditions of each model can be visually presented to the user. As a result, the user can intuitively recognize to what extent the design conditions must be adjusted to select different models, and can select a model that meets the user's needs. In addition, the user can re-evaluate the operating conditions or design conditions while observing the price and delivery date of each model, and select a product that better meets the needs.

[0267] The component purchase assistance device (1) of the eighth scheme of the present disclosure may be such that, based on the seventh scheme, the design conditions are configured to be changeable by the user, and when the design conditions are changed by the user, the candidate components are selected again based on the changed design conditions.

[0268] For example, in the initial stage of a project in a fluid delivery system, there is a range of permissible operating conditions and design conditions, and there is often room for change. On the other hand, in the stage of arranging equipment parts, in order to facilitate the selection and implementation by suppliers, and in order to prevent suppliers from selecting products that do not meet user requirements, most of the specific operating conditions and design conditions are set and prompted to the suppliers. In this way, even if there is a range of permissible operating conditions and design conditions, in order to reduce the time required for the arrangement process or rework, the range of conditions has to be intentionally narrowed. Therefore, especially when there is room to choose a more favorable product in terms of price or delivery time, equipment parts are sometimes arranged without noticing this room.

[0269] In contrast, according to the component purchase support device (1) of the present embodiment, the design conditions can be changed by the user, so the user can change the design conditions by a simple operation such as moving the design conditions displayed in the orthogonal coordinate system to the desired coordinates. Furthermore, when the design conditions are changed, the candidate components are selected again based on the changed design conditions. In this way, the candidate components are automatically selected based on the changed design conditions, so the user can obtain information on candidate components corresponding to multiple design conditions without worrying about the time required for the arrangement procedure of the equipment components or rework, and can expand the scope of component selection.

[0270] The component purchasing assistance device (1) of the ninth scheme of the present invention is based on any one of the above-mentioned first to eighth schemes, and the above-mentioned component selection unit has: a necessary condition determination unit (43), which determines whether the above-mentioned input conditions meet the necessary conditions required for selecting the model of the equipment component; and an inquiry assistance unit (44), which assists the user in making inquiries to the supplier when it is determined that the necessary conditions are not met.

[0271] According to the component purchase assistance device (1) of the above scheme, when the input conditions are insufficient, the device components that meet the user's needs can be arranged by obtaining the cooperation of the supplier.
