Description

Technical Field

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

[0002] For example, when a buyer (hereinafter, sometimes also referred to as a "user") wishes to purchase a device component, generally, the following steps need to be taken between the buyer and the supplier. Here, as an example of a buyer, a device manufacturer etc. may be cited.

[0003] First, the prospective purchaser creates a component order specification, presents the draft specification, and requests a price estimate from the supplier. The supplier creates a price estimate based on the draft specification and presents it to the prospective purchaser. The prospective purchaser adjusts the specifications and places an order with the supplier who requested the price estimate.

[0004] Thus, in the past, many processes were required until the order was placed, so ordering parts required time and labor. 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 compared to the effort of making the estimate, which is sometimes not cost-effective. Therefore, it may lead to disadvantages for the prospective purchaser, such as delayed response to other cases and the price provided being estimated to be higher.

[0005] Conventional systems that reduce the number of parts procurement steps and labor, such as the one disclosed in Patent Document 1, include a manufacturing order support device. Upon receiving part drawing data from a manufacturer, this device analyzes the drawing data to determine the part's processability, then requests estimates from multiple fabricators capable of processing the part and provides the manufacturer with the estimated prices. Thus, the manufacturing order support device disclosed in Patent Document 1 mediates transactions between manufacturers and fabricators, thereby reducing the burden on both parties involved in parts procurement.

[0006] Patent Document 2 discloses a device that can automatically estimate the price or delivery date of a set of multiple components constituting a mechanical device and provide the estimated price or delivery date to a user.

[0055] Hereinafter, an embodiment of a purchase support device 1 , a purchase support method, and a purchase support program according to an embodiment of the present disclosure will be described with reference to the drawings.

[0056] The purchase support device 1 of the present embodiment is a device suitable for purchasing a component set (part set) constituting a fluid conveying system during equipment construction accompanying construction work in the fluid conveying system, for example.

[0057] Here, "fluid transport system engineering" refers to, for example, the planning, design, and procurement of systems for transporting media such as gas, liquid, and solids incorporated into equipment. This includes mixed gas-liquid systems (e.g., steam and wastewater), mixed gas-solid systems (e.g., air-assisted transport of pulverized coal), and mixed liquid-solid systems (e.g., slurries).

[0058] "Equipment parts" refer to, for example, fluid conducting elements and equipment used in fluid conveying systems. Examples of fluid conducting elements include piping, telescopic / flexible pipes (bellows, flexible pipes, etc.), elbows, bends, 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 heat-insulating machines (heat-insulating parts), piping support parts, machine support stands, steel frames, etc. If further expanded, industrial machines such as boilers, freezers, dehydrators, and dryers that receive and discharge fluids can also be included as targets.

[0059] Figure 32 The relationship between the equipment components is shown in FIG.

[0060] Some equipment components cannot be specified unless the design considers the flow rate range and equipment operation. Examples of such equipment components include safety valves, control valves (including dry and oil-operated ones), piping components such as heat exchangers, desuperheaters, orifices, and steam traps, and conveying equipment such as pumps, fans, blowers, and compressors.

[0061] There are equipment components that require electrical connections such as power supply, measurement, and control signals. Examples of such equipment components include solenoid valves, electric valves, control valves (including air-operated and oil-operated), pumps, fans, blowers, compressors, conveyors, and other conveying machines and instruments.

[0062] Hereinafter, a purchase support device 1 according to the present embodiment will be described with reference to the drawings.

[0063] Figure 1 : is a diagram showing the network structure of the purchase support device 1 of this embodiment. Figure 1 As shown, the purchase support device 1 is configured to be connectable to the customer terminal 70 and the supplier terminal 80 via a network, enabling information to be exchanged between them. Examples of networks include Wi-Fi, mobile communication systems (3G, 4G, 5G, 6G, LTE, etc.), wireless LANs (Local Area Networks), and wired LANs.

[0064] 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 purchase support apparatus 1 is not limited to this example.

[0065] exist Figure 1In the example, the 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 purchase support device 1 and the client terminal 70 and the network connecting the purchase support device 1 and the supplier terminal 80 may be different.

[0066] Figure 2 This is a schematic diagram showing an example of the hardware structure of the purchase support device 1. The purchase support device 1 is a so-called server (computer). Figure 2 As shown in the example, the main components include a CPU (processor) 11, an auxiliary storage device 12 for storing programs executed by the CPU 11 (e.g., a purchase assistance program), a main memory 13 that functions as a workspace when executing each program, and a communication device 14 for connecting to a network. These components are connected via a bus 18. The 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 operating system for controlling the entire purchase assistance device 1, various drivers for operating the hardware of peripheral devices, application programs for implementing the purchase assistance device 1, and various data and files. Examples of the auxiliary storage device 12 include semiconductor memories, magnetic disks, and magneto-optical disks.

[0067] The client terminal 70 is an information processing device used by users who wish to purchase a fluid delivery system composed of equipment components, or in this embodiment, a plurality of equipment components. The client terminal 70 is, for example, a desktop PC, a notebook PC, a tablet PC, a tablet terminal, a mobile phone terminal, a smartphone, etc. The structure of the client terminal 70 is well known, so a detailed description is omitted, but similar to the above-mentioned 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 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 for controlling the client terminal 70 such as Windows (registered trademark), iOS (registered trademark), and Android (registered trademark), various drivers for performing hardware operations on peripheral devices, applications for realizing the functions of the client terminal 70 described later, and various data and files.

[0068] Supplier terminal 80 is an information processing device used by suppliers of equipment components. Here, "supplier" refers to, for example, a company that manufactures and sells equipment components. If a manufacturer of equipment components uses a trading company as an agent to sell its products, the combination of the manufacturer and the trading company is referred to as the "supplier."

[0069] The supplier terminal 80 is, for example, a desktop PC, a notebook PC, a tablet PC, a tablet terminal, a mobile phone terminal, a smartphone, etc. The structure of the supplier terminal 80 is well known, so a detailed description is omitted, but similar to the above-mentioned 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 (liquid crystal display, 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 devices, applications for realizing the functions of the supplier terminal 80 described later, and various data and files.

[0070] Next, the functions of the purchase support device 1 according to this embodiment will be described. Figure 3 This is a functional configuration diagram illustrating an example of the functions of the purchase assistance device 1 according to this embodiment. As an example, the series of processes for implementing the functions described below are stored as a program (e.g., a purchase assistance program) in the auxiliary storage device 12 of the purchase assistance device 1. The CPU 11 reads this program into the main memory 13 and executes it to implement the various functions. Alternatively, the program may be pre-installed in the auxiliary storage device 12 of the purchase assistance device 1, provided as stored on a computer-readable storage medium, or distributed via a wired or wireless communication device. Computer-readable storage media include magnetic disks, magneto-optical disks, CD-ROMs, DVD-ROMs, semiconductor memories, and the like.

[0071] like Figure 3 As shown, the purchasing assistance device 1 may also include a standard component database 21 and a supplier component database 22. It may also include a fluid calculation module database 23 and an ordering database 24. The purchasing assistance device 1 may also include a condition input assistance unit 31, a standard system configuration generation unit 32, a standard system selection unit 33, a system component selection unit 34, a selection candidate generation unit 35, a system configuration generation unit 36, a specification confirmation unit 37, and an ordering assistance unit 38. The purchasing assistance device 1 may also include a selection condition storage unit 41, a system configuration storage unit 42, a component candidate storage unit 43, and a selected component storage unit 44, as storage areas for various data when selecting system components. Each component is described below. For ease of understanding, the example of a newly established fluid delivery system for delivering water from an existing (or pre-existing) tank to another existing tank is used for illustration. However, this is not limiting; the same process can be applied to all fluids and all equipment and components that deliver and receive fluids.

[0072] 〔Standard Parts Database 21〕

[0073] The standard component database 21 stores information on a plurality of standard components related to fluid delivery systems. For example, for each equipment component, representative specification information, representing information on representative specifications, is stored in association with the functions possessed by the component. This representative specification information is predetermined based on, for example, the specifications of each equipment component provided by each supplier. For example, in the case of a pump, the representative specification is predetermined based on the caliber (inlet / outlet) and motor output.

[0074] Figure 4 An example of information stored in the standard component database 21 of this embodiment is shown. Figure 4 As shown, the standard component name, component category, representative specification information, and function are associated with each other and registered in the standard component database 21. Here, the component category and the representative specification information are distinguished, but the component category can also be incorporated into the representative specification information and made a part of the representative specification information.

[0075] Here, the "function" corresponds to the "required function" inputted by the condition input assisting unit 31 described later. Standard components associated with the "function" corresponding to the "required function" selected by the user in the condition input assisting unit 31 described later are selected as components of the fluid transport system.

[0076] In order to easily extract this information in the standard component database 21, for example, a method (hereinafter referred to as "mapping format") may be adopted in which the standard component name is used as a keyword (name used as a tag) and representative specification information is stored and processed in association with the keyword.

[0077] 〔Supplier Parts Database 22〕

[0078] The supplier parts database 22 stores information on supplier parts sold by suppliers. For example, for each supplier, the model number of each device part sold by that supplier is stored in association with its specification data. The device part model number can also be associated with the product name, price, and delivery date. Option information can also be associated with the device part model number.

[0079] Figure 5 An example of supplier parts information stored in the supplier parts database 22 of this embodiment is shown. Figure 5 As shown, the model number, product name, specification information, price and delivery date are registered for each supplier in association with each other in the supplier parts database 22. In the supplier parts database 22, these information can also be managed in the form of a map, for example.

[0080] Price and delivery information can be updated by each supplier at any time. This allows you to create quotes using the latest data. This allows you to provide users with highly reliable quotes. The price can include not only the price of the equipment components, but also various other expenses required to ship the product.

[0081] Optional information includes, for example, optional products (consumables, special tools, etc.), dispatch of an instructor for installation, operational adjustments during trial operation, troubleshooting and other technical support services, and specification upgrade services (for example, corrosion-resistant overlay welding, advanced painting, additional inspections, additional drawings, etc.). Detailed information can be registered in association with various options in the optional information. For example, detailed information on spare parts can include delivery date, price, and replacement period. Detailed information on technical support and optional services can include provision period, price, features, advantages, and precautions.

[0082] 〔Fluid Calculation Module Database 23〕

[0083] The fluid calculation module database 23 stores a plurality of calculation modules that associate standard components (e.g., standard component names) with standard calculation equations. The fluid calculation module database 23 also stores a plurality of calculation modules that associate supplier components (e.g., supplier model numbers) provided by various suppliers with supplier-specific calculation equations.

[0084] In each calculation module, for example, a pressure loss calculation formula for calculating the outlet pressure from the fluid pressure at the inlet of a component is registered.

[0085] [Order Database 24]

[0086] The order database 24 stores, for example, order-related information for each user. This order-related information includes past order history, current order reservation information, and order status. By examining the contents of the order database 24, it is possible to understand what equipment components each user has purchased and what equipment components they plan to purchase next.

[0087] [Condition Input Assisting Unit 31]

[0088] The condition input assisting unit 31 obtains the required specifications and required functions related to the fluid delivery system that the user wishes to purchase as selection conditions. For example, the required specifications include at least one of the inlet design temperature, the inlet design pressure, the outlet design temperature, and the outlet design temperature. The required specifications may also include pre-set operating conditions. Pre-set operating conditions may include, for example, at least one of the inlet tank pressure, water level, and fluid temperature, and the outlet tank internal pressure.

[0089] The required functions are the functions that the user wants the fluid conveying system to have. As an example, they include anti-backflow function, inlet separation function, outlet separation function, pump inlet pressure measurement function, pump outlet pressure measurement function, flow measurement function, function to prevent foreign matter from entering the pump, drainage function, etc.

[0090] Moreover, the selection conditions may also include at least one of the type of fluid being transported, the driving source of the fluid, information related to the starting point and end point of the fluid transport, application standards, and specifications of the piping joints. The selection conditions may also include desired conditions for selecting equipment components and priority research conditions. For example, examples of options for priority research conditions include flow rate or piping diameter. The larger the piping diameter, the smaller the pressure loss during fluid flow, which can reduce losses during operation. On the other hand, the larger the piping diameter, the greater the material cost and the larger the space required. When planning a fluid transport system, it is necessary to comprehensively evaluate the performance during operation, material cost, spatial feasibility, delivery time, etc. to determine the optimal solution. The purpose of selecting desired conditions and priority research conditions is to obtain research results that are close to the conditions desired by the user in advance.

[0091] Examples of the type of fluid include air, gas, water, saturated water, saturated steam, and superheated steam. Examples of the driving source for the fluid include a fan, a pump, and potential energy.

[0092] Examples of fluid transfer starting point information include starting point coordinates, connection destination, and connection specifications. For liquid transfer, examples of connection destinations include the pipe socket at the bottom of the tank (below the liquid surface), the pipe socket of the tank barrel (below the liquid surface), and the valve outlet (below the liquid surface). Examples of connection specifications include flange, screw-in, union, and welding.

[0093] Examples of fluid delivery destination information include the destination coordinates, connection destination, and connection specifications. For liquid delivery, examples of connection destinations include the tank top socket (above the liquid surface), the barrel socket (above the liquid surface), the barrel socket (below the liquid surface), the valve inlet (above the liquid surface), and the valve inlet (below the liquid surface). Examples of connection specifications include flange, screw-in, union, and welding.

[0094] Examples of applicable standards include JIS, ASME, ANSI, and JPI.

[0095] Examples of joint specifications include flange, screw-in, union, and welding.

[0096] Examples of desired conditions for selecting equipment components include a required flow rate, a design pressure, a design temperature, a desired pipe diameter, a desired minimum pipe diameter, and a desired maximum pipe diameter.

[0097] As the preferred examination conditions, for example, flow rate and pipe diameter can be cited.

[0098] The selection conditions may also include various delivery-related information, such as the latest allowable delivery date, the maximum allowable price, the desired shipping destination, packaging specifications, and the transportation method. By entering the latest allowable delivery date or the maximum allowable price as a selection condition, delivery dates or prices that do not meet the user's expectations can be eliminated. This improves user convenience and reduces the computational processing burden of the purchase support device 1.

[0099] For example, the condition input assisting unit 31 generates screen data for causing the client terminal 70 to display a condition input screen for inputting these selected conditions, and transmits the data to the client terminal 70. The input of the selected conditions can also be performed in an interactive format, for example. To facilitate input by less experienced engineers or to facilitate their understanding, an image or the like can be used to encourage input.

[0100] Figures 6 to 17 1 is a diagram showing an example of an interactive condition input screen generated by the condition input support unit 31. The condition input support unit 31 uses Figures 6 to 17 The condition input screens shown are sequentially displayed on the client terminal 70 , allowing the user to input required conditions and obtain information required for selecting equipment components constituting the fluid transport system.

[0101] Figure 6 This is the screen for entering conditions for selecting the purchase object. Figure 7 This is the condition input screen for selecting the fluid type. Figure 8 This is the condition input screen for selecting the driving source of the fluid. Figure 9 This is the condition input screen for inputting the coordinates of the fluid delivery start point and delivery end point. Figure 10 This is the condition input screen for selecting the connection destination and connection specifications of the fluid delivery starting point. Figure 11 This is a condition input screen for selecting the connection destination and connection specifications of the fluid delivery destination. Figure 12 This is the condition input screen for selecting the application standard. Figure 13 This is the condition input screen for selecting the connector specifications. Figure 14 This is the condition input screen for selecting additional functions (request functions). Figure 15 This is the condition input screen for inputting the set design conditions. Figure 16 This is the condition input screen for entering the set operating conditions. Figure 17This is the condition input screen for inputting desired conditions and priority research conditions. For ease of understanding, the example of setting up a new fluid delivery system for delivering water from an existing (already installed) tank to another existing tank is used for explanation. Figure 15 、 Figure 16 Although the already set design conditions and the already set operating conditions are input in , when a new setting is made, a new design condition and a new operating condition can also be input.

[0102] Multiple input modes may be provided for inputting selected conditions. For example, the user may be presented with multiple input modes and be prompted to select any one of them. Furthermore, the condition input assisting unit 31 may generate a condition input screen corresponding to the input mode selected by the user and transmit it to the client terminal 70.

[0103] As an example of an input mode, there are a detailed input mode, a simple input mode, a model input mode, and the like. The detailed input mode is generally a mode for inputting all the conditions required when selecting a component from a supplier. This mode is for users who are proficient in engineering in fluid conveying systems. The simple input mode is a mode for limiting the input items to the main items for unskilled users. For example, it is a mode in which several conditions among the conditions input in the detailed input mode are omitted. The model input mode is a mode for inputting a supplier name or model number, and is a mode for users who want to purchase the same parts as those of an already installed device, or users who want to pre-investigate the supplier's catalog and decide on the model number.

[0104] By configuring a plurality of input modes in this manner, the user can select a desired input mode, and a service corresponding to the user's engineering ability and needs can be provided.

[0105] 〔Input Support Section〕

[0106] The condition input support unit 31 may include, for example, an input support unit 311 (see Figure 3 ) The input support unit 311 temporarily inputs a selection condition that has not been input by the user among a plurality of selection conditions based on past accumulated data or a preset initial value.

[0107] For example, the input support unit 311 previously stores initial values ​​related to the design conditions and operating conditions. If the selected conditions are not input in the design conditions and operating conditions, the initial values ​​are temporarily input. Alternatively, representative values ​​based on past performance values ​​or the like may be temporarily input instead of the initial values.

[0108] Furthermore, the input assisting unit 311 may ask questions to the user according to a predetermined questioning process, and through a dialogue with the user's responses to the questions, the user may enter any missing selection criteria. If a provisional entry is made through the input assisting unit 311, the provisional entry may be prompted to the user to confirm whether the provisional entry deviates from the user's assumptions.

[0109] For example, equipment components are subject not only to constraints related to the components themselves, such as shape and strength, but also to constraints imposed on the fluid flowing within them. Therefore, selecting appropriate components requires a certain degree of experience. Consequently, inexperienced users may not know what conditions to set and may find it difficult to do so independently. In such situations, by providing input assistance unit 311 to assist user input, even users lacking engineering experience in fluid delivery systems can enter appropriate conditions for arranging equipment components.

[0110] [Selection Condition Storage Unit 41]

[0111] The selection conditions, such as the required specifications and required functions, obtained by the condition input assisting unit 31 are stored in the selection condition storage unit 41. For example, the selection conditions may be stored in a mapped format. For example, the selection conditions may store user-entered conditions in association with each major item, such as the inlet conditions, outlet conditions, required functions, design pressure and temperature, and required specifications. New information may also be added to the selection conditions by performing predetermined calculations based on the conditions obtained from the user. For example, when selecting equipment components, the nominal pressure (temperature and pressure level) is calculated based on the set pressure and set temperature, and the nominal pressure is used to select the component. Therefore, the selection conditions may also include a call pressure (temperature and pressure level) based on the set pressure and set temperature obtained from the client terminal 70.

[0112] [Standard System Structure Generation Unit 32]

[0113] Based on the selection conditions stored in the selection condition storage unit 41, the standard system configuration generation unit 32 identifies a plurality of standard components constituting the fluid delivery system from the standard component database 21 and generates a standard system configuration diagram in which the plurality of identified standard components are connected. Specifically, the standard system configuration generation unit 32 generates a standard system configuration diagram serving as a system configuration diagram of the fluid delivery system by arranging the plurality of identified standard components along the fluid delivery path from the delivery start point to the delivery end point.

[0114] Specifically, the standard system configuration generator 32 retrieves corresponding standard components from the standard component database 21 based on selected conditions (e.g., required function, pipe diameter, grade, and connection method). The retrieved standard components are then sequentially arranged on the fluid transport path to create a standard system configuration diagram. The fluid transport path is generated based on the start and end coordinates, established specifications, and the start and end points are connected by pipes based on the values ​​entered as the desired pipe diameter.

[0115] After generating the standard system configuration diagram, the standard system configuration generating unit 32 generates a standard system configuration adjustment screen including the standard system configuration diagram, and displays the screen data on the display unit of the client terminal 70 . Figure 18 This is a diagram showing an example of a standard system configuration adjustment screen. In the standard system configuration adjustment screen, a standard system configuration diagram generated based on selected conditions is displayed, and information such as required functions, required specifications, and established specifications as the selection conditions of the standard system configuration diagram are also displayed. Figure 18 In the standard system structure diagram shown, each module surrounded by a dot-dash line is a component module corresponding to each standard component.

[0116] In the standard system configuration adjustment screen, the standard system configuration diagram is configured so that the user can perform at least one of the following operations: adding piping, changing routes, changing the position and arrangement order of component modules, and adding or deleting required functions. Figure 18 In the figure, a two-dimensional system configuration diagram is shown, but it can also be displayed as a three-dimensional system configuration diagram such as an equal-division diagram using an isometric projection or a 3D display.

[0117] The user creates a desired system configuration diagram by moving component modules, changing the dimensions of the piping connecting the component modules, and so on in the system configuration adjustment screen. When the diagram is complete, the user presses the send button BT1. This transmits the system configuration diagram information determined by the user to the purchase support device 1.

[0118] When a drawing (e.g., 2D CAD data, 3D CAD data, etc.) of peripheral components of a fluid delivery system is provided to the purchase support device 1, these peripheral components may be included as a background in the standard system configuration diagram and displayed. By displaying the peripheral components as a background, standard components can be appropriately positioned, taking into account the placement of the surrounding components.

[0119] For example, in equipment components, there are cases where there are constraints on the upstream and downstream equipment structures or the length of straight pipes. For example, in order to keep the measurement error within the reference, the orifice flowmeter has the constraint of ensuring a certain length of straight pipe length before and after it. When arranging different types of measuring instruments, there is a desired setting order. For example, a thermometer inserts the measurement point into the fluid, which becomes the main cause of disturbing the flow of the fluid and may affect the measurement results of pressure or flow. Therefore, there are constraints such as setting a thermometer on the downstream side of the pressure gauge and flowmeter. In electromagnetic flowmeters, the flow measurement part needs to be filled with fluid at all times, so there are constraints on the piping path. In safety valves, if the pressure loss of the tail flow is too high, in other words, if the piping is too thin or too long, the planned blowout volume cannot be ensured, so there are constraints on the length and diameter of the piping.

[0120] Therefore, the standard system configuration generator 32 may also have the function of determining the appropriateness of the placement of standard components and their positional relationships with surrounding components, taking into account the aforementioned constraints. It then displays standard components that require change and those most suitable for change, color-coded according to their importance, on the standard system configuration diagram. This assists the user in modifying the position of standard components, thereby helping to prevent problems and reduce research time.

[0121] The standard system configuration generator 32 may also have a function of suggesting changes to standard components. For example, it may suggest that the dimensions of a flange joint are inconsistent, but that the dimensions will fall within a specified range if it is changed to a welded joint.

[0122] Furthermore, the standard system configuration generation unit 32 may also be equipped with a function that graphically suggests improvements to the piping route that would reduce costs or maintain minimal cost within the current standard system configuration adjustment screen. The user can select one or more evaluation axes, not limited to price, but also including delivery time, low pressure loss, compliance, recommendation, and piping length. Improvement proposals can also be graphically suggested based on machine learning results. This allows the user to be provided with the optimal piping route, reducing their workload.

[0123] Furthermore, the standard system configuration generator 32 may also have the following function: when a certain device component is moved, when the device component is selected, the predicted result of the change in the evaluation of the predetermined evaluation axis is displayed as a difference in color around the selected device component. In this way, by visually indicating the destination of the device component, the user can easily determine the configuration of the standard component. As an example of an evaluation axis, there are the possibility of price improvement, no price change, and the level of concern for price change: small, medium, large, etc. If there is an area that cannot be moved due to the instrument specifications, the area can also be visually indicated.

[0124] Furthermore, the standard system configuration generator 32 can also include the ability to improve the evaluation of pre-set evaluation axes or propose improvements to these evaluation axes. This allows for the anticipated improvement of not only spatial configuration optimization but also improvements based on the redesign of equipment components. For example, such proposals can be generated based on past examples accumulated during the purchase of the auxiliary device 1, machine learning results, or pre-registered typical improvement patterns.

[0125] Furthermore, the standard system configuration generator 32 may also include a function that estimates typical labor hours based on the specifications of the connectors and piping routing information for each selected standard component, calculates the estimated construction cost using a typical labor hour price, and displays the estimated construction cost as a sum total of the system preparation price. Furthermore, the estimated labor hours may be included as one of the aforementioned evaluation axes. By preparing an evaluation axis that also includes construction costs, this can help reduce the total cost of system implementation for users.

[0126] [System configuration storage unit 42]

[0127] The system configuration storage unit 42 stores information based on a standard system configuration diagram determined by a user. Figure 19 4 is a diagram showing an example of information stored in the system configuration storage unit 42. Figure 19 As shown, in the system configuration storage unit 42, information about the various standard components that make up the fluid delivery system is tabulated and stored in descending order of their connection. This information about each standard component may also include the module name, standard component name, nominal pipe diameter (size), nominal pressure (temperature and pressure rating), starting point coordinates, end point coordinates, and length. This information is generated based on the specification information of each standard component stored in the standard component database 21. Reference delivery dates, reference prices, and other information may also be stored in the system configuration storage unit 42 in an associated manner.

[0128] In this manner, information (size (nominal diameter), nominal pressure (temperature-pressure level), coordinate information, etc.) necessary for component selection in subsequent processing is registered in association in the system configuration storage unit 42 .

[0129] 〔Standard System Selection Department 33〕

[0130] The standard system selection unit 33 selects a plurality of standard components having different specifications from among the preset main standard components stored in the system configuration storage unit 42, and generates a plurality of standard system configuration candidates. Examples of the main standard components include pumps and pipes.

[0131] Furthermore, for each standard system configuration among the plurality of standard system configuration candidates, the standard system selection unit 33 retrieves calculation modules corresponding to the standard components that constitute the configuration from the fluid calculation module database 23 and connects the retrieved calculation modules in a connection order to generate a calculation module chain. Furthermore, the standard system selection unit 33 calculates the outlet conditions of the fluid delivery system, such as pressure, temperature, and flow rate, by providing input conditions, such as inlet conditions of pressure, temperature, and flow rate, to the calculation module chain.

[0132] Figure 20 An example of a chain of computing modules is shown in FIG. Figure 20 For example, "Piping" represents the standard piping calculation module, "Bv" represents the standard ball valve calculation module, "Tpiece" represents the standard T piece calculation module, "Pump" represents the standard pump calculation module (including the regulator for caliber adjustment), "FT" represents the standard flow meter calculation module, and "Elbow" represents the standard elbow calculation module.

[0133] The standard system selection unit 33 inputs the fluid input conditions, specifically, pressure, temperature, and flow rate, to the first calculation module BL1 of the calculation module chain. The outlet conditions calculated in the first calculation module BL1 are provided as input conditions to the next calculation module BL2. Furthermore, the outlet conditions are calculated sequentially in the order in which the calculation modules are connected, thereby calculating the output conditions in the calculation module BLn, which ultimately becomes the end point. This output condition becomes the outlet condition of the entire system in the candidate standard system structure. Temperature, flow rate, and pressure are input as inlet conditions, but regarding temperature and flow rate, it is also possible to assume that they are constant from inlet to outlet and only calculate the pressure loss.

[0134] The standard system selection unit 33 generates a calculation module chain for each of the plurality of standard system configuration candidates, and calculates the outlet condition of each fluid transport system.

[0135] The standard system selection unit 33 may include other calculation functions such as a fluid flow diagnosis function at a highest arrival point, a NPSH (Net Position Suction Head) calculation function, a water hammer diagnosis function, a noise calculation function, and a function for diagnosing the suitability of the design pressure and temperature of each component.

[0136] The fluid flow diagnostic function at the highest arrival point determines the coordinates of the highest arrival point of the fluid delivery system and its components based on the coordinate information of each standard component. The calculation module corresponding to the component determines whether the inlet and outlet pressure conditions are above predetermined thresholds. This function confirms whether a flow rate exceeding the minimum flow rate can be maintained at the component located at the highest arrival point when fluid is delivered through the selected standard component. If it is determined that the minimum flow rate cannot be maintained, adjustments can be made, for example, by changing the specifications of the pumps in the candidate standard system configuration, to ensure the minimum flow rate at the component located at the highest arrival point.

[0137] The NPSH calculation function determines whether the constraints on the suction side of a pump or compressor are met. The noise calculation function determines whether the noise level is below a predetermined threshold. The water hammer diagnosis function determines whether water hammer is likely to occur.

[0138] The function for diagnosing the suitability of each component's design pressure and temperature determines whether the operating pressure and temperature of each component is lower than the design pressure and temperature, or in other words, whether operating conditions are within the nominal pressure range of each component. For example, when boosting pressure using a pump, the nominal pressure of subsequent equipment components may vary depending on the pump's performance. By considering these factors in diagnosing the suitability of each component's design pressure and temperature, users can be informed of the need to select appropriate components, such as those capable of withstanding higher pressures.

[0139] The standard system selection unit 33 generates a standard system selection screen showing information of main standard components (pump specifications, flow rate, standard pipe nominal diameter) and flow rate-head relationship characteristics for each standard system configuration candidate, and transmits it to the client terminal 70 .

[0140] Figure 21 This figure shows an example of a standard system selection screen. The standard system selection screen displays the assumed operating conditions for each standard system configuration candidate. Specifically, the standard system selection screen displays the pump model, flow rate, reference piping nominal diameter, and flow rate for each standard system configuration candidate. Diagnostic results for each of the aforementioned calculation functions, such as whether the minimum flow rate can be ensured at the highest arrival point, NPSH calculation results, water hammer risk, noise level, and the suitability of the design pressure and temperature of each component, can also be displayed as part of the judgment process.

[0141] By displaying the diagnosis results of each calculation function in this manner, it is possible to provide the user with judgment materials based on various viewpoints, and to select a standard system configuration candidate that best meets the user's needs.

[0142] Yoke love, you can also display price, delivery date and other information on the standard system selection screen.

[0143] In the standard system selection screen, the operating point of the entire system can also be displayed. Figure 21 In [1], the operating point of the entire system is displayed on the graph (for example, as the intersection of the performance curve and the resistance curve in the Q (flow)-H (head) plane). This operating point is calculated by taking into account the system output conditions calculated in the calculation module chain described above.

[0144] By presenting the user with the operating point and specification information for the entire system, the user can select and purchase multiple equipment components that form a complete fluid transport system with the same ease as selecting a single equipment component. This also allows for research into the configuration of surrounding equipment.

[0145] Furthermore, the standard system selection screen may include an input section for instructing to increase or decrease flow rate requirements or pipe diameter requirements if a desired candidate is not found among the presented standard system configuration candidates. When these input sections are operated, standard components are reselected according to the input instructions, multiple standard system configuration candidates are newly generated, and the aforementioned outlet conditions, etc., are calculated for each standard system configuration candidate.

[0146] On the standard system selection screen, the user selects any standard system configuration candidate that meets the requirements and presses the send button BT2 , whereby information on the standard system configuration candidate selected by the user is sent to the purchase support device 1 .

[0147] The standard system selection unit 33 updates the information of the system configuration storage unit 42 based on the information of the standard system configuration candidate selected by the user. That is, the system configuration storage unit 42 is updated based on the information of the standard system configuration candidate selected by the user. Figure 19 Various information (names and specifications of standard components that make up the fluid transportation system, etc.) are displayed.

[0148] [System Component Selection Section 34]

[0149] The system component selection unit 34 selects one or more supplier components corresponding to each standard component constituting the standard system configuration diagram from the supplier component database 22. Specifically, the system component selection unit 34 selects, from the supplier component database 22, device components (hereinafter referred to as "supplier components") corresponding to each standard component stored in the system configuration storage unit 42. In this case, the system component selection unit 34 may select multiple supplier components sold by different suppliers for each standard component.

[0150] For example, for each standard component, the system component selection unit 34 selects multiple supplier components that meet the requirements based on the standard component name and specification data (e.g., design pressure, design temperature, nominal diameter, etc.), and obtains the price, delivery date, and option information of the supplier components from the supplier component database 22. For example, in the case of a valve, the supplier component is selected based on the nominal pressure and size (e.g., nominal diameter).

[0151] Here, depending on the supplier, unique requirements may be required when selecting supplier components. In this case, it is necessary to ask the user for this information. In such a case, the system component selection unit 34 may also ask the user for additional input by displaying an input form for inputting the required information on the client terminal 70, for example.

[0152] In this way, when the system component selection unit 34 selects one or more supplier components (for example, supplier components of Company A, Company B, Company C, etc.) corresponding to each standard component such as piping, ball valves, and pumps, the information of the selected supplier components is associated with each standard component and stored in the component candidate storage unit 43.

[0153] [Part Candidate Storage Unit 43]

[0154] In the component candidate storage unit 43 , information on supplier components is stored in association with each module constituting the standard system configuration diagram. Figure 22 : is a diagram showing an example of data stored in the component candidate storage unit 43. Figure 22 As shown, in the component candidate storage unit 43, the supplier, model, product name, specification information, price and delivery date information are stored in association with the component element (module name). Here, the supplier, model, product name, specification information, price and delivery date information are written as long as the information obtained from the supplier component database 22 (see Figure 5 ) can be used.

[0155] [Selection candidate generation unit 35]

[0156] The selected candidate generating unit 35 generates at least one system configuration candidate that is a combination of supplier components constituting the fluid transport system based on the plurality of supplier components stored in the component candidate storing unit 43 , and transmits the system configuration candidate to the client terminal 70 .

[0157] Specifically, the selected candidate generator 35 generates a plurality of system configuration candidates according to predetermined evaluation criteria from a plurality of supplier components stored in the component candidate storage 43. Examples of the evaluation criteria include lowest price, shortest delivery time, low price and short delivery time, and recommendation.

[0158] The lowest price is a candidate combination of supplier components with the lowest total cost of the equipment components that make up the fluid conveying system, and the shortest delivery time is a candidate combination of supplier components with the earliest delivery time of the equipment components that make up the fluid conveying system. Low price and short delivery time are evaluated based on both price and delivery time. For example, the combination of supplier components with the highest evaluation value is obtained by substituting each value into an evaluation formula that includes price and delivery time as parameters. Recommendations are, for example, combinations of components with the highest overall evaluation value, using other evaluation indicators in addition to price and delivery time. For example, by substituting the evaluation values ​​of price, delivery time, and reputation (past user evaluation information) into a predetermined evaluation value formula, a comprehensive evaluation value is calculated for each supplier component, and the combination of supplier components with the highest calculated comprehensive evaluation value is determined.

[0159] The evaluation value calculation formula can be set arbitrarily. For example, each item can be evaluated with a full score of 10 and the value can be obtained by adding the values. Alternatively, a weight coefficient can be set for each item and the value obtained by multiplying the score of each item by the weight coefficient can be added. Machine learning can also be performed using the past performance of the operator of the purchase support device 1, the past performance of similar designs, or the past performance based on the operation of the purchase support device 1, and the recommendations can be displayed in order of closest to the machine learning results.

[0160] When a plurality of system configuration candidates are generated based on the respective evaluation criteria, the selection candidate generating unit 35 generates a comparison selection screen showing the system configuration candidates in a comparable manner, and transmits the screen to the client terminal 70 .

[0161] Figure 23 : is a diagram showing an example of a comparison selection screen. Figure 23 In the comparison selection screen shown, the system configuration candidate with the lowest price is shown as mode 1, the system configuration candidate with the shortest delivery period is shown as mode 2, the system configuration candidate evaluated from the two aspects of low price and short delivery period is shown as mode 3, and the recommended system configuration candidate is shown as mode 4. For each system configuration candidate, the supplier, product name, price, delivery period and user evaluation of each equipment component are displayed. Figure 23 In the comparison selection screen, the user can select a desired mode.

[0162] The comparison selection screen includes an individual selection button BT3 . The individual selection button BT3 is a button for transitioning to an individual selection screen where the user can select each device component. Figure 24This shows an example of the individual selection screen. The individual selection screen displays supplier component information for each component that makes up the fluid delivery system, in other words, for each module as shown in the standard system structure diagram. Supplier components can be displayed in order of price, delivery date, or recommendation. The display order can be changed by switching tabs.

[0163] When the user selects any system configuration candidate in the comparison selection screen, or selects a supplier component corresponding to each component constituting the fluid transport system by specifying the supplier component of each component in the individual selection screen, the user presses the OK button BT4 .

[0164] Thus, the supplier parts information corresponding to each component selected by the user is transmitted to the purchase support apparatus 1. The supplier parts information selected by the user is stored in the selected parts storage unit 44 in association with the information of each component.

[0165] As an indicator for the user to select a candidate system configuration, the selected candidate generator 35 may display, for example, evaluation values ​​for the system's carbon dioxide emissions and greenhouse gas emissions. These evaluation values ​​may be based on either the operating state or the non-operating state, or both. By using both evaluation values, it is possible to provide evaluation values ​​throughout the product lifecycle.

[0166] For example, the selection candidate generating unit 35 can calculate the carbon dioxide emission amount by the following method.

[0167] - Based on the specifications of each supplier's components that make up each system configuration candidate and the user-entered operation plan (information on annual operating hours, etc.), the system's overall power consumption is calculated and multiplied by the CO2 generation per unit of power to calculate the CO2 emissions during operation.

[0168] - Calculate the carbon dioxide emissions associated with manufacturing, transportation, and disposal based on data on greenhouse gas emissions associated with the manufacturing and disposal of each equipment component.

[0169] In this way, by presenting the carbon dioxide emission amount as one indicator when selecting a system configuration candidate, the user can select a system configuration candidate while also considering the carbon dioxide emission amount.

[0170] [Selected component storage unit 44]

[0171] The selected component storage unit 44 stores information on the supplier's components corresponding to each component constituting the fluid transport system. The selected component storage unit 44 also stores coordinate information corresponding to each supplier's component. Figure 254 is a diagram showing an example of data stored in the selected component storage unit 44. Figure 25 As shown, the supplier component information and coordinate information corresponding to each device component are associated and registered in the selected component storage unit 44. The supplier component information is obtained from the component candidate storage unit 43, and the coordinate information is obtained from the system configuration storage unit 42.

[0172] In the selected parts storage unit 44, each supplier's parts may be stored, for example, Figure 18 The arrangement order of the equipment components from the transport start point to the transport end point in the system configuration diagram shown is stored in the form of a list.

[0173] [System configuration generation unit 36]

[0174] The system configuration generation unit 36 ​​generates a system configuration diagram connecting the delivery start point and the delivery end point based on the supplier component information and coordinate information stored in the selected component storage unit 44, generates a system configuration adjustment screen including the generated system configuration diagram, and sends the screen data to the client terminal 70. Figure 26 An example of the system configuration adjustment screen is shown below. Figure 26 As shown in the system structure adjustment screen, the system structure generated using supplier parts is different from the system structure generated using supplier parts. Figure 1 The detailed information of the selected part is displayed. Figure 26 The system configuration diagram shown includes piping adjustment parts (modification parts). This indicates the piping error caused by using supplier parts instead of standard parts.

[0175] Right now, Figure 18 The standard system structure shown is made using standard components. Figure 26 The system configuration diagram shown is created using supplier components. Therefore, due to the difference between the typical specifications of standard components and the specifications of supplier components, the position of the delivery destination may differ from the coordinates of the delivery destination required by the user. Therefore, this difference is shown in the system configuration diagram as a piping adjustment component, allowing the user to adjust the position of each component (pump, etc.) and the length of the piping to eliminate the need for this piping adjustment component. This can eliminate the difference when using supplier components and meet the requirements of the requirements input screen (see Figure 9 ) The conditions of the transport start point and transport end point entered in .

[0176] When the adjustment is complete, the user presses the send button BT5. This transmits the adjusted system configuration diagram information, specifically the adjusted coordinate information and lengths of each component, to the purchase support device 1. Upon receiving the adjusted information, the system configuration generation unit 36 ​​updates the coordinate information and lengths of each component stored in the selected component storage unit 44 based on this information.

[0177] [Specifications Confirmation Department 37]

[0178] The specification confirmation unit 37 recalculates performance based on the adjusted system configuration data, i.e., the updated data stored in the selected component storage unit 44. For example, the specification confirmation unit 37 retrieves the calculation modules corresponding to the various supplier components stored in the selected component storage unit 44 from the multiple calculation modules stored in the fluid calculation module database 23 and combines the retrieved calculation modules based on the configuration order to create a calculation module chain. Furthermore, the specification confirmation unit 37 calculates the outlet conditions (e.g., pressure, temperature, flow rate) of the fluid delivery system by applying input conditions (e.g., pressure, temperature, flow rate) to the generated calculation module chain. The specification confirmation unit 37 may also include other calculation functions, such as a function for diagnosing fluid flow at the highest arrival point, calculating NPSH, diagnosing water hammer, calculating noise, and diagnosing the suitability of the design pressure and temperature of each component.

[0179] When the performance calculation is completed, the specification confirmation unit 37 generates a final confirmation screen including the performance calculation result and transmits it to the client terminal 70. As a result, the final confirmation screen is displayed on the display unit of the client terminal 70.

[0180] Figure 27 This figure shows an example of a final confirmation screen. The final confirmation screen displays the operating points when the fluid conveying system is constructed using the selected components (parts from the supplier selected by the user). Specifically, the pump model, flow rate, reference pipe nominal diameter, and flow rate values ​​are displayed on the final confirmation screen. The diagnostic results of each of the above-mentioned calculation functions can also be displayed, such as the diagnostic results of whether the minimum flow rate can be ensured at the highest arrival point, NPSH, water hammer risk, noise level, and the appropriateness of the design pressure and temperature of each component. In addition, the final confirmation screen also displays price and delivery information, and displays detailed information on the selected component (such as supplier, model, product name, price, quantity, etc.).

[0181] Then, when the user presses the confirmation button BT6 , the order reservation is finalized, and the order reservation information is transmitted to the purchase support device 1 .

[0182] [Order Support Department 38]

[0183] Upon receiving the order reservation information from the client terminal 70 , the order support unit 38 supports the ordering of the supplier parts that have been finally confirmed.

[0184] First, the order support unit 38 stores the information of the supplier parts finally confirmed by the user in the order database 24 as order reservation information. The order database 24 stores information related to orders for each user. Examples of order-related information include order reservation information, order history, and order status. The order reservation information includes the data of the supplier parts stored in the selected parts storage unit 44 (see Figure 25 ).

[0185] Next, the order support unit 38 generates an order reservation screen based on the order reservation information of the fluid transport system stored in the order database 24 , and transmits the screen to the client terminal 70 .

[0186] The order reservation screen displays the price, delivery date, and order reservation date of the fluid transport system. The order reservation screen also displays various functions for assisting the user in placing an order for the system. Figure 28 This is a diagram showing an example of an order reservation screen. Figure 28 The order reservation screen shown displays option selection, estimate confirmation, specification confirmation, and price quote update as examples of functions for assisting system ordering.

[0187] For example, option selection is a function that presents the user with option information for the entire fluid delivery system or for each supplier component that constitutes the fluid delivery system, allowing the user to select the desired option information. For example, when the user presses the option selection button BT7 on the order reservation screen, the order support unit 38 displays an option selection screen on the client terminal 70 for selecting option information. Specifically, the order support unit 38 retrieves option information related to each supplier component stored in the selected component storage unit 44 from the supplier component database 22, generates an option selection screen displaying the retrieved option information for each supplier component, and transmits it to the client terminal 70. The option selection screen may include not only option information for each supplier component but also option information for the entire system.

[0188] Figure 29 FIG is a diagram showing an example of an option selection screen. Figure 29 As shown in FIG, in the option selection screen, option information is displayed for the entire system and each supplier component. As option information, for example, information on option content, price, and delivery date can be listed. Figure 29The illustrated option selection screen displays a complete set of gaskets as system-wide option information. For example, flange mating requires inserting gaskets. The type of gasket can be determined based on the fluid type, design temperature, and design pressure. When the user selects one or more options on the option selection screen and presses the OK button BT12, information about the selected options is transmitted to the purchase support device 1. This information (including details, price, and delivery date) is stored in the order reservation information.

[0189] Optional information can include parts sales related to the insulation plan. For example, the type and thickness of insulation can be displayed as optional information. By planning insulation at the same time as purchasing the fluid delivery system, the user can be helped to reduce work hours.

[0190] The quote confirmation function presents the user with a quote for the supplier components currently scheduled for ordering. For example, when the user presses the quote confirmation button BT8 on the order reservation screen, the order support unit 38 retrieves price and delivery information for each supplier component that constitutes the fluid delivery system from the order reservation information and creates a quote based on this information. If the order reservation information includes optional information, a quote is created that also includes this optional information. Furthermore, a quote confirmation screen is generated to present the user with the quote and displayed on the client terminal 70. Figure 30 This figure shows an example of a quote confirmation screen. The quote confirmation screen can also display delivery date information and the quote's validity period.

[0191] Specification confirmation is a function that presents the user with specifications for the supplier components currently scheduled for ordering. For example, when a user presses the Specification Confirmation button BT9 on the order reservation screen, the order support unit 38 retrieves the specification information for each supplier component that constitutes the fluid delivery system from the order reservation information and creates a specification based on this information. Furthermore, a Specification Confirmation screen is generated to present the user with the specifications and displayed on the client terminal 70.

[0192] The quote update function allows users to request an update based on the current order reservation information for an order whose quote is about to expire or has already expired. For example, when a user presses the quote update button BT10 on the order reservation screen, the order support unit 38 retrieves price and delivery date information for each supplier component that makes up the fluid delivery system from the order reservation information and updates the quote based on this information. The updated quote information is then sent to the client terminal 70 for notification to the user.

[0193] Also, on the order reservation screen (refer to Figure 28) in which the user presses the order button BT11, order instruction information for instructing the order is transmitted to the purchase support device 1. Upon receiving the order instruction information, the order support unit 38 sends a request to each supplier terminal 80 (see Figure 1 ) to place an order for a component from a supplier, and to change the order reservation information into order information. Even after the order is placed, information can be exchanged between the user and the supplier via the purchase support device 1 in the event of an inquiry or the like.

[0194] For example, the order support unit 38 may also have a function to support various inquiries from ordering to delivery, such as inquiries about the delivery location, delivery date, etc. This can reduce the burden of individual delivery-related adjustments that has traditionally been a burden on both users and suppliers.

[0195] The purchasing assistance device 1 can also assist users in managing delivered items by attaching information identification labels or barcodes to items delivered from suppliers. For example, a fluid delivery system may consist of multiple supplier components, and therefore, different suppliers may deliver these components to the user sequentially. In this case, by providing shared system identification information for supplier components used in the same fluid delivery system, users can easily understand which fluid delivery system a received supplier component belongs to. This system identification information can also be managed in the purchasing assistance device 1.

[0196] Next, we will refer to Figure 31 The purchase support method of this embodiment will be briefly described. The following series of processes are stored as a program (eg, a purchase support program) in the auxiliary storage device 12 of the purchase support apparatus 1 and are implemented by the CPU 11 reading the program into the main memory 13 and executing it.

[0197] Figure 31 1 is a flowchart showing an example of the processing steps of the purchase support method of this embodiment. For the sake of convenience, the purchase support method will be described below in the case where a user wishes to purchase a fluid delivery system that delivers water from one tank to another.

[0198] First, purchase the auxiliary device 1 Figures 6 to 17 The interactive condition input screen shown is transmitted to and displayed on the client terminal 70, allowing the user to enter various information required for purchasing equipment components for the fluid transport system (SA1: condition input assistance step). The information entered in the condition input assistance step is stored as selected conditions in the selected condition storage unit 41.

[0199] Next, the purchase support device 1 generates a standard system configuration diagram of the fluid delivery system based on the selected conditions, allowing the user to adjust the standard system configuration (SA2: standard system configuration generation process). Specifically, based on the selected conditions stored in the selected condition storage unit 41, the standard components constituting the fluid delivery system are obtained from the standard component database 21, and the standard components are sequentially arranged on the piping path connecting the delivery start point to the delivery end point, thereby generating a standard system configuration diagram. In addition, the standard system configuration adjustment screen (see Figure 18 ) is displayed on the display unit of the client terminal 70, so that the user can adjust the standard system configuration diagram. The information based on the standard system configuration diagram determined by the user is stored in the system configuration storage unit 42 (refer to Figure 19 ).

[0200] Next, the purchase support device 1 generates a plurality of standard system configuration candidates and generates a standard system selection screen (see FIG. Figure 21 ), allowing the user to select a desired standard system configuration candidate (SA3: Standard System Selection Process). At this point, the purchase support device 1 may also generate a calculation module chain for each standard system configuration candidate, calculate the system's exit conditions, and display these exit conditions on the standard system selection screen. When the user selects any standard system configuration candidate, the purchase support device 1 updates the information in the system configuration storage unit 42 based on the information about the selected standard system configuration candidate.

[0201] Next, the purchase support device 1 selects one or more supplier parts corresponding to each standard part stored in the system configuration storage unit 42 from the supplier parts database 22 and stores information of the selected supplier parts in the part candidate storage unit 43 in association with each standard part (SA4: system part selection step).

[0202] Next, the purchase support device 1 generates a plurality of system configuration candidates from a plurality of supplier components stored in the component candidate storage unit 43 according to a predetermined evaluation standard, and generates a comparison selection screen (see FIG. 1 ) that displays these system configuration candidates in a manner that allows comparison. Figure 23 ), allowing the user to select a desired selection mode candidate (SA5: selection candidate generation step). When the user selects any system configuration candidate, the purchase support device 1 stores the selected system configuration candidate information together with the coordinate information in the selected component storage unit 44.

[0203] Next, the purchase support device 1 generates a system configuration diagram from the delivery start point to the delivery end point based on the information and coordinate information of the supplier parts stored in the selected parts storage unit 44, and generates a system configuration adjustment screen including the generated system configuration diagram (see Figure 26), for the user to adjust the system configuration (SA6: system configuration generation step). When the user adjusts the system configuration, the purchase support device 1 updates the information in the selected component storage unit 44 based on the adjusted system configuration.

[0204] Next, the purchase support device 1 performs performance calculation based on the adjusted system configuration diagram and generates a final confirmation screen including the performance calculation results (see Figure 27 ) for the user to confirm (SA7: specification confirmation process). When the user confirms the order reservation, the purchase support device 1 stores the information of the supplier parts that have been finally confirmed as order reservation information in the order database 24.

[0205] Next, the purchase support device 1 generates an order reservation screen based on the order reservation information for the fluid delivery system stored in the order database 24, and provides the user with information such as options to select (SA8: order support process). Furthermore, upon receiving an order instruction from the user, the purchase support device 1 orders the supplier components from each supplier based on the order reservation information and updates the order reservation information to the order information.

[0206] As described above, according to the purchase assistance device 1, purchase assistance method, and purchase assistance program of this embodiment, a user simply inputs selection criteria to identify multiple standard components that meet the selection criteria and generates a standard system configuration diagram composed of the identified multiple standard components. Furthermore, one or more supplier components corresponding to each standard component constituting the standard system configuration diagram are selected, and based on the selected multiple supplier components, at least one system configuration candidate is generated as a combination of supplier components constituting a fluid transport system and presented to the user as a selection candidate.

[0207] For example, when selecting equipment components, each supplier may have different selection criteria and calculation formulas. Performing calculations for each supplier simultaneously would require significant computational effort, potentially consuming time to research specifications and conduct price assessments. In contrast, the purchasing assistance device 1 of this embodiment first generates a standard system configuration diagram using standard components that meet the selection criteria as a first stage. Then, in a subsequent second stage, the corresponding supplier components are identified for each standard component. This allows for the selection of supplier components, minimizing computational effort while taking into account user needs, thereby shortening processing time.

[0208] By selecting a desired system configuration from the presented selection candidates, the user can easily select multiple equipment components that comprise the fluid delivery system. This allows for easy and efficient arrangement of multiple equipment components, effectively shortening the time between condition input and purchase.

[0209] While the present disclosure has been described above using the embodiments, the technical scope of the present disclosure is not limited to the scope described in the above embodiments. Various changes or improvements can be made to the above embodiments without departing from the scope of the disclosure, and the methods in which such changes or improvements are made are also included in the technical scope of the present disclosure.

[0210] The processing flow described in the above embodiment is merely an example, and unnecessary steps may be deleted, new steps may be added, or the processing order may be changed without departing from the scope of the present disclosure.

[0211] For example, purchasing auxiliary device 1 does not require Figure 3 All the functions shown may be partially omitted. For example, the standard system configuration generating unit 32 and the standard system selecting unit 33 may be omitted, and the system component selecting unit 34 may select supplier components that meet the selection conditions.

[0212] about Figure 31 The series of processes shown does not need to be performed in full, and some of them can be omitted. For example, the standard system configuration generation step (SA2) and the standard system configuration selection step (SA3) can be omitted, and supplier components that meet the selection criteria can be selected in the system component selection step (SA4).
