Description

[Technical field]

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

[0002] For example, when a prospective purchaser (hereinafter sometimes referred to as a "user") purchases a plant part, the following process is generally required between the purchaser and the supplier. Here, examples of prospective purchasers include plant manufacturers and factories that operate plants. First, the buyer creates an order specification for the part, and requests a quote from the supplier by presenting the created order specification. The supplier creates a quote based on the order specification and presents it to the buyer. The buyer adjusts the specifications and places an order with the supplier who requested the quote.

[0003] As described above, in the past, ordering parts required a lot of time and effort because many steps were required before an order could be placed. In addition, quotations could only be obtained from suppliers that the prospective purchaser inquired about themselves. This caused inconveniences, for example, in that even if there was a supplier offering similar parts under better conditions (e.g., lower prices, shorter delivery times, better service, etc.), it was not possible to reach that supplier. Furthermore, from the supplier's perspective, in the case of small orders for parts with low unit prices, the sales and profits were low compared to the effort required to prepare an estimate, and it was not worth it. This could lead to disadvantages for prospective purchasers, such as delays in responding to other orders or relatively high quoted prices.

[0004] Conventionally, as a system for reducing the process and labor of procuring parts, there is a manufacturing outsourcing support device disclosed in Patent Document 1, for example. When this manufacturing outsourcing support device receives drawing data of a part from a manufacturer, it analyzes the received drawing data to determine whether the part can be processed, requests quotes from multiple processors that can process the part, and returns the estimated price to the manufacturer. In this way, the manufacturing outsourcing support device disclosed in Patent Document 1 mediates between the manufacturer and processor, making it possible to reduce the burden on both parties regarding parts procurement. Moreover, Patent Document 2 discloses a device that can automatically estimate the price or delivery date of a set of multiple parts that make up a machine device and provide it to a user. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent No. 6462945 [Patent Document 2] Patent No. 6415492 Summary of the Invention [Problem to be solved by the invention]

[0006] However, the devices disclosed in Patent Documents 1 and 2 are systems specialized for processed products and cannot be immediately applied to procuring plant parts. In other words, it is necessary to determine which plant parts to purchase after considering parameters specific to a fluid transport system, such as flow rate and pressure loss, in addition to constraints such as design pressure, operating pressure, design temperature, and operating temperature. For this reason, with the devices disclosed in Patent Documents 1 and 2, it was impossible to select parts that satisfy all of the constraints when estimating the entire fluid transport system consisting of multiple plant parts. Furthermore, the operation of a fluid transport system requires not only plant parts that transport fluids, but also electrical parts that supply electricity as a driving power source to pumps, instruments, etc.

[0007] The present disclosure has been made in consideration of the above circumstances, and aims to provide a purchasing support device, a purchasing support method, and a purchasing support program that can provide a user with multiple plant components and electrical components that make up a fluid transport system. [Means for solving the problem]

[0013] Hereinafter, 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. The purchase support device 1 according to this embodiment is a device suitable for purchasing a group of parts (a complete set of parts) that constitute a fluid transport system, for example, in plant engineering involving engineering of the fluid transport system. Here, "engineering in fluid transport systems" refers to planning, designing, and procuring systems that transport media such as gas, liquid, and solid, which are installed in a plant. Media include gas-liquid mixed systems (for example, a mixed system of steam and condensate), gas-solid mixed systems (for example, air transport of pulverized coal), and liquid-solid mixed systems (for example, slurry).

[0014] In addition, the term "plant parts" refers to, for example, fluid conducting elements and equipment used in a fluid transport system. Examples of fluid conducting elements include pipes, expandable / contractible pipes (bellows, flexible tubes, etc.), bend pipes, elbows, joints, and valves (manual valves, motorized valves, solenoid valves, control valves, safety valves, check valves, etc.). Examples of equipment include instruments, transport equipment, strainers, accumulators, steam traps, and desuperheaters. Examples of instruments include pressure gauges, thermometers, and flowmeters. Examples of transport equipment include pumps, fans, blowers, compressors, and conveyors. Examples of peripheral parts include heat-insulating equipment (heat-insulating members), pipe support members, equipment support racks, and steel frames. By further expanding the scope, industrial machines that receive and discharge fluids, such as boilers, freezers, dehydrators, and dryers, can also be included.

[0015] Figure 33 shows the relationships between plant parts. There are some plant parts whose specifications cannot be selected until a design is completed that takes into consideration the operation of the plant, such as the range of changes in flow rate, etc. Examples of such plant parts include piping parts such as safety valves, control valves (including air-operated and oil-operated), heat exchangers, desuperheaters, orifices, and steam traps, as well as transport equipment such as pumps, fans, blowers, and compressors. In addition, there are plant parts (hereinafter referred to as "electrically related parts") that require electrical connection with electrical equipment (power supply equipment such as power supplies, and instrumentation equipment such as control devices, measuring devices, and data input / output devices that handle measurement and control signals). Examples of such plant parts include solenoid valves, motor-operated valves, control valves (including air-operated and oil-operated), pumps, fans, blowers, compressors, transport equipment such as conveyors, and instruments.

[0016] The purchase support device 1 according to this embodiment will be described below with reference to the drawings. Fig. 1 is a diagram showing the network configuration of a purchase support device 1 according to this embodiment. As shown in Fig. 1, purchase support device 1 is connectable to a client terminal 70 and a supplier terminal 80 via a network, and is configured to be able to send and receive information between them. Examples of the network include Wi-Fi, mobile communication systems (3G, 4G, 5G, 6G, LTE, etc.), wireless LAN (Local Area Network), and wired LAN.

[0017] FIG. 1 illustrates one client terminal 70 and one supplier terminal 80, but the numbers of client terminals 70 and supplier terminals 80 connected to purchase support device 1 are not limited to this example. 1, the purchase support device 1, the client terminal 70, and the supplier terminal 80 are all connected by the same network, but this is not limited to this example. For example, the network connecting the purchase support device 1 and the client terminal 70 may be different from the network connecting the purchase support device 1 and the supplier terminal 80.

[0018] FIG. 2 is a schematic diagram showing an example of the hardware configuration of the purchase support device 1. The purchase support device 1 is a so-called server (computer), and as shown in FIG. 2, the main components are a CPU (processor) 11, an auxiliary storage device 12 for storing programs (e.g., a purchase support program) executed by the CPU 11, a main memory 13 that functions as a work area when each program is executed, and a communication device 14 for connecting to a network, and these components are connected via a bus 18. The purchase support device 1 may further 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 purchase support device 1, various drivers for operating the hardware of peripheral devices, applications for realizing the purchase support device 1, and various data and files. Examples of the auxiliary storage device 12 include semiconductor memory, magnetic disks, and magneto-optical disks.

[0019] The client terminal 70 is an information processing device used by a user who wishes to purchase a plant part, in this embodiment, a fluid transport system composed of a plurality of plant 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 smartphone, or the like. The configuration of the client terminal 70 is publicly known, so a detailed description will be omitted. However, like the above-mentioned purchase support device 1, the client terminal 70 includes a CPU, an auxiliary storage device, a main memory, a communication device, and an input unit. Furthermore, the client terminal 70 includes a display unit (liquid crystal display, organic EL display, etc.). Furthermore, the client terminal 70 may include 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), Android (registered trademark), various drivers for operating the hardware of peripheral devices, applications for implementing the functions of the client terminal 70 described later, and various data and files.

[0020] The supplier terminal 80 is an information processing device used by a supplier who sells plant parts. Here, "supplier" means, for example, a company that manufactures and sells plant parts. When a plant part manufacturing company sells its own products through a trading company as an agent, the combination of the plant part manufacturing company and the trading company is called a "supplier."

[0021] 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 configuration of the supplier terminal 80 is known, so a detailed description will be omitted. However, like the above-mentioned purchase support device 1, the supplier terminal 80 includes a CPU, an auxiliary storage device, a main memory, a communication device, and an input unit. Furthermore, the supplier terminal 80 includes a display unit (liquid crystal display, organic EL display, etc.). Furthermore, the supplier terminal 80 may include a microphone and a speaker. The auxiliary storage device stores, for example, an OS for controlling the entire supplier terminal 80 such as Windows (registered trademark), iOS (registered trademark), Android (registered trademark), etc., various drivers for operating the hardware of peripheral devices, applications for implementing the functions of the supplier terminal 80 described later, and various data and files.

[0022] Next, the functions of the purchase support device 1 according to this embodiment will be described. FIG. 3 is a functional configuration diagram showing an example of the functions of the purchase support device 1 according to this embodiment. A series of processes for realizing each function shown below is stored as a program (e.g., a purchase support program) in the auxiliary storage device 12 of the purchase support device 1, and the CPU 11 reads this program into the main memory 13 and executes it to realize various functions. The program may be pre-installed in the auxiliary storage device 12 of the purchase support device 1, provided in a state stored in a computer-readable storage medium, or distributed via wired or wireless communication means. The computer-readable storage medium may be a magnetic disk, a magneto-optical disk, a CD-ROM, a DVD-ROM, a semiconductor memory, or the like.

[0023] 3, the purchase support device 1 may include a standard parts database 21, a supplier parts database 22, and an electrical parts database 23. The purchase support device 1 may also include a fluid calculation block database 24 and an order database 25. The purchase support device 1 may also include, for example, a condition input support unit 31, a parts selection unit, an electrical-related parts extraction unit 34, an electrical parts identification unit 35, an electrical system generation unit 36, etc. The purchase support device 1 may also include an order support unit 37. In addition, the purchase support device 1 may be equipped with a selection condition storage unit 41, a standard system storage unit 42, a part candidate storage unit 43, and a selected part storage unit 44 as storage areas for storing various data when selecting system parts. Each part will be explained below. For ease of understanding, a new fluid transport system that transports water from one existing (pre-existing) tank to another existing tank will be used as an example, but the present invention is not limited to this and the same handling is possible for any fluid and any device or part that a fluid flows in and out of. In this embodiment, a case will be described in which a standard parts selection unit 32 and a supplier parts selection unit 33 are provided as the parts selection unit.

[0024] [Standard Parts Database 21] The standard parts database (parts database) 21 stores information on a plurality of standard parts related to a fluid transport system. For example, the standard parts database 21 stores representative specification information, which is information on a representative specification of each plant part, in association with the functions of the part. The representative specification information is determined in advance based on the specifications of each plant part (supplier part) provided by each supplier. For example, in the case of a pump, the representative specification is determined in advance based on the bore (inlet / outlet) and the motor output. In this way, a standard part means a plant part with a representative specification.

[0025] Fig. 4 shows an example of information stored in the standard parts database 21 according to this embodiment. As shown in Fig. 4, the standard parts database 21 registers standard part names, part types, representative specification information, and functions in association with one another. Also, here, a distinction is made between part types and representative specification information, but the part types may be incorporated into the representative specification information and may be part of the representative specification information. Here, the "function" corresponds to a "required function" inputted in the condition input support unit 31 described later. A standard part associated with a "function" corresponding to the "required function" selected by the user in the condition input support unit 31 described later is selected as a component part of the fluid transport system. In order to make this information easy to extract, the standard parts database 21 may store and process representative specification information linked to the standard part name as a key (a landmark name), for example (hereinafter referred to as a "map format").

[0026] [Supplier Parts Database 22] The supplier parts database (parts database) 22 stores information on plant parts sold by suppliers (hereinafter referred to as "supplier parts"). For example, the supplier parts database 22 stores, for each supplier, the model numbers and specification data of the plant parts sold by that supplier in association with each other. The model numbers of the plant parts may also be associated with information on the product name, price, and delivery date. The model numbers of the plant parts may also be associated with option information. Fig. 5 shows an example of supplier part information stored in the supplier part database 22 according to this embodiment. As shown in Fig. 5, the model number, product name, specification information, price, and delivery date are registered for each supplier in the supplier part database 22 in such a manner that they are associated with each other. In the supplier part database 22, this information may be managed as data in, for example, a map format.

[0027] The price and delivery date information can be updated by each supplier at any time. This makes it possible to create quotations using the latest data, and to provide highly reliable quotations to users. In addition to the price of the plant parts, various expenses required for shipping the products may also be registered.

[0028] [Electrical Parts Database 23] In the electric component database 23, identification information and specification data are stored in association with each other for each of a plurality of electric components. Examples of electric components include input / output modules, breakers (switches), fuses (circuit breakers), wiring (power cables, communication cables, etc.), etc. Examples of input / output modules include analog input (AI) modules, analog output (AO) modules, digital input (DI) modules, digital output (DO) modules, input / output (I / O) systems, etc.

[0029] [Fluid calculation block database 24] The fluid calculation block database 24 stores a plurality of calculation blocks in which standard parts (e.g., standard part names) are associated with standard calculation expressions. The fluid calculation block database 24 also stores a plurality of calculation blocks in which supplier parts (e.g., supplier model numbers) provided by each supplier are associated with the supplier's unique calculation expressions. In each calculation block, for example, a pressure loss calculation formula for calculating the outlet pressure from the fluid pressure at the inlet of a component is registered.

[0030] [Order Database 25] The order database 25 stores, for example, information about orders for each user. Information about orders includes past order history, current order reservation information, order status, etc. By checking the contents of the order database 25, it is possible to know what plant parts and electrical parts each user has purchased and what they are planning to purchase in the future.

[0031] [Condition input support unit 31] The condition input support unit 31 acquires the required specifications and required functions of the fluid transport system that the user wishes to purchase as selection conditions. For example, the required specifications include at least one of the inlet side design temperature, the inlet side design pressure, the outlet side design temperature, and the outlet side design temperature. The required specifications may also include existing operating conditions. The existing operating conditions include at least one of the inlet side tank pressure, the water surface height, and the fluid temperature, and the outlet side tank pressure, for example. Required functions are functions that the user wants the fluid transport system to have, and examples include a backflow prevention function, an inlet partition function, an outlet partition function, a pump inlet pressure measurement function, a pump outlet pressure measurement function, a flow measurement function, a function to prevent foreign matter from entering the pump, a drain removal function, etc.

[0032] Furthermore, the selection conditions may include at least one of the following: the type of fluid to be transported, the driving source of the fluid, information on the start point and end point of the transport of the fluid, the applicable standard, and the pipe joint specifications. The selection conditions may also include desired selection conditions for plant parts and prioritized examination conditions. For example, an example of a choice of prioritized examination conditions is a flow rate or a pipe diameter. The larger the pipe diameter, the smaller the pressure loss when the fluid flows and the smaller the loss during operation, but the larger the pipe diameter, the higher the material cost and the larger the required space. When planning a fluid transport system, it is necessary to comprehensively evaluate the performance during operation, material cost, spatial feasibility, delivery date, etc., and determine the optimal solution. The desired selection conditions and prioritized examination conditions are intended to quickly obtain examination results that are close to the conditions desired by the user.

[0033] Examples of the type of fluid include air, gas, water, saturated water, saturated steam, superheated steam, etc. Examples of the driving source of the fluid include a fan, a pump, potential energy, etc. Examples of information on the start point of fluid transport include start point coordinates, connection destination, and connection specifications. Examples of connection destinations when transporting liquid include the pipe stub at the bottom of the tank (below the liquid level), the pipe stub at the tank body (below the liquid level), and the valve outlet (below the liquid level). Examples of connection specifications include flanges, threaded, unions, and welding. Examples of information on the end point of fluid transport include end point coordinates, connection destination, and connection specifications. Examples of connection destinations when transporting liquid include the pipe stub at the top of the tank (above the liquid level), the pipe stub at the tank body (above the liquid level), the pipe stub at the tank body (below the liquid level), the valve inlet (above the liquid level), and the valve inlet (below the liquid level). Examples of connection specifications include flanges, threaded, unions, and welding.

[0034] Applicable standards include, for example, JIS, ASME, ANSI, JPI, etc. Examples of joint specifications include flange, threaded, union, and welded. The desired selection conditions for the plant parts include, for example, 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. Priority conditions to be considered include, for example, flow rate and pipe diameter.

[0035] The selection conditions may also include various information related to delivery, such as the allowable latest delivery date, the allowable maximum price, and the desired delivery destination, packaging specifications, and transportation method. In this way, by inputting the allowable latest delivery date and the allowable maximum price as selection conditions, it is possible to eliminate delivery dates and prices that do not meet the user's wishes. This makes it possible to improve user convenience and reduce the computational burden on the purchase support device 1.

[0036] For example, the condition input support unit 31 generates screen data for displaying a condition input screen for inputting these selection conditions on the client terminal 70, and transmits the screen data to the client terminal 70. The selection conditions may be input in an interactive format, for example. Also, to allow even an inexperienced user to easily input the selection conditions and to help the user grasp the image, the input may be prompted using diagrams or the like.

[0037] 6 to 17 are diagrams showing examples of interactive condition input screens generated by the condition input support unit 31. The condition input support unit 31 causes the client terminal 70 to sequentially display the condition input screens shown in Fig. 6 to 17, thereby allowing the user to input necessary conditions and acquiring information required for selecting plant parts that constitute the fluid transport system.

[0038] FIG. 6 is a condition input screen for selecting the purchase item, FIG. 7 is a condition input screen for selecting the type of fluid, FIG. 8 is a condition input screen for selecting the drive source of the fluid, FIG. 9 is a condition input screen for inputting the coordinates of the start point and end point of the fluid transport, FIG. 10 is a condition input screen for selecting the connection destination and connection specifications of the start point of the fluid transport, FIG. 11 is a condition input screen for selecting the connection destination and connection specifications of the end point of the fluid transport, FIG. 12 is a condition input screen for selecting the applicable standard, FIG. 13 is a condition input screen for selecting the fitting specifications, FIG. 14 is a condition input screen for selecting additional functions (required functions), FIG. 15 is a condition input screen for inputting existing design conditions, FIG. 16 is a condition input screen for inputting existing operating conditions, and FIG. 17 is a condition input screen for inputting the desired selection conditions and prioritized consideration conditions. For ease of understanding, a case where a fluid transport system for transporting water from an existing (pre-existing) tank to another existing tank is newly installed is described as an example, and therefore, in Figs. 15 and 16, the design conditions and operating conditions of the existing system are input. However, in the case of a new installation, the design conditions and operating conditions of the new system may be input. In addition to the above-mentioned condition input screen, a condition input screen may be presented that allows the user to input information required for arranging electrical components. For example, a condition input screen may be presented that allows the user to input information on existing electrical equipment. This condition input screen may be configured to allow, for example, a drawing of the existing electrical equipment to be attached.

[0039] For input of the selection conditions, multiple input modes may be provided. For example, multiple input modes may be presented to the user, and the user may select one of them. Then, the condition input support unit 31 may generate a condition input screen according to the input mode selected by the user, and transmit the screen to the client terminal 70.

[0040] Examples of input modes include a detailed input mode, a simple input mode, and a model number input mode. The detailed input mode is a mode in which all conditions required for a supplier to select a part are generally input. This mode is intended for users who are familiar with engineering in fluid transport systems. The simple input mode is a mode in which input items are limited to the main items for inexperienced users. For example, some of the conditions input in the detailed input mode are omitted. The model number input mode is a mode in which a supplier name or model number is input, and is intended for users who wish to purchase the same parts as existing plant parts, or users who have already decided on a model number for which they want to research a supplier's catalog, etc. In this way, by providing a plurality of input modes and allowing the user to select the desired input mode, it becomes possible to provide services that correspond to the user's engineering capabilities and needs.

[0041] [Input assistance section] The condition input support unit 31 may include, for example, an input assistance unit 311 (see FIG. 3). The input assistance unit 311 provisionally inputs, among a plurality of selection conditions, a selection condition that has not been input by the user based on past accumulated data or a preset initial value. For example, the input assistance unit 311 holds initial values ​​related to design conditions and operating conditions in advance, and provisionally inputs the initial values ​​when no selection conditions are input for the design conditions and operating conditions. Also, instead of the initial values, representative values ​​based on past performance values, etc. may be provisionally input.

[0042] Furthermore, the input assistance unit 311 may ask the user questions according to a predetermined question flow, and have the user input the missing selection conditions in an interactive format in which the user answers the questions. Also, when the input assistance unit 311 performs provisional input, the provisionally input conditions may be presented to the user to have the user confirm whether or not they deviate from the user's expectations.

[0043] For example, since plant parts have constraints not only on the part itself, such as shape and strength, but also on the fluid flowing inside, a certain degree of experience is required to select appropriate parts. For this reason, an inexperienced user may not know what conditions to set and may find it difficult to set conditions independently. In such a case, by providing an input assistance unit 311 to assist the user in inputting, even a user with little engineering experience in fluid transport systems can input appropriate conditions required for arranging plant parts.

[0044] [Selection condition storage unit 41] Selection conditions such as required specifications and required functions acquired by the condition input support unit 31 are stored in the selection condition storage unit 41. For example, the selection conditions may be stored in a map format. For example, the selection conditions are stored by associating conditions input by the user with each of the main items such as inlet conditions, outlet conditions, required functions, design pressure temperature, and required specifications. In addition, new information may be added to the selection conditions by performing a predetermined calculation based on the conditions acquired from the user. For example, in the selection of plant parts, a nominal pressure (temperature pressure rating) is calculated from the set pressure and set temperature, and parts are selected using the nominal pressure. For this reason, the selection conditions may include a nominal pressure (temperature pressure rating) based on the set pressure and set temperature acquired from the client terminal 70.

[0045] [Standard parts selection section 32] The standard parts selection unit 32 selects from the standard parts database 21 a plurality of standard parts (plant parts) that constitute the fluid transport system based on the selection conditions. For example, the standard parts selection unit 32 includes a standard system generation unit 321 and a standard system selection unit 322 .

[0046] [Standard system generation unit 321] The standard system generation unit 321 identifies a plurality of standard parts constituting a fluid transport system from the standard parts database 21 based on the selection conditions stored in the selection condition storage unit 41, and generates a standard system configuration diagram by connecting the identified plurality of standard parts. Specifically, the standard system generation unit 321 generates a standard system configuration diagram, which is a system configuration diagram of a fluid transport system, by arranging the identified plurality of standard parts on a fluid transport path from the transport start point to the transport end point.

[0047] More specifically, the standard system generation unit 321 acquires suitable standard parts from the standard parts database 21 based on information on the selection conditions (e.g., required functions, pipe diameter, rating, connection style). Then, the acquired standard parts are arranged in order on the fluid transport path to generate a standard system configuration diagram. At this time, the fluid transport path is generated based on the start point coordinates, end point coordinates, existing specifications, etc., and the start point to the end point are connected by piping based on the value input as the desired pipe diameter.

[0048] When the standard system generation unit 321 generates the standard system configuration diagram, it generates a standard system configuration adjustment screen including the standard system configuration diagram, and displays this screen data on the display unit of the client terminal 70. Fig. 18 is a diagram showing an example of the standard system configuration adjustment screen. The standard system configuration adjustment screen displays the standard system configuration diagram generated based on the selection conditions, as well as information such as the required functions, required specifications, and existing specifications that are the selection conditions for the standard system configuration diagram. In the standard system configuration diagram shown in Fig. 18, each block surrounded by a dashed line is a component block corresponding to each standard component.

[0049] In this standard system configuration adjustment screen, the standard system configuration diagram is configured so that the user can perform at least one of adding piping, changing the route, changing the position and arrangement order of part blocks, and adding and deleting required functions, etc. Note that, although shown as a two-dimensional system configuration diagram in Fig. 18, it may be displayed as a three-dimensional system configuration diagram such as an isometric drawing using an isometric projection or a 3D display. The user creates a desired system configuration diagram by performing operations such as moving component blocks on this system configuration adjustment screen and changing the dimensions of the pipes connecting the component blocks, and when the drawing is completed, presses the send button BT1. This causes the information on the system configuration diagram confirmed by the user to be sent to the purchase support device 1.

[0050] Furthermore, when drawings (e.g., 2D CAD data, 3D CAD data, etc.) of peripheral parts on which the fluid transport system is to be installed are provided to the purchase support device 1, these peripheral parts may be displayed as part of the standard system configuration diagram as a background. In this way, by displaying the peripheral parts as a background, it becomes possible to place the standard parts in appropriate positions, taking into consideration the placement of the peripheral parts, etc.

[0051] Also, for example, there are cases where plant components have restrictions on the equipment configuration and straight pipe length upstream and downstream. For example, an orifice flow meter has a restriction that a certain straight pipe length must be secured before and after it in order to keep the measurement error within a standard. Also, when arranging different types of instruments, there is a desirable installation order. For example, a thermometer is a factor that disturbs the flow of the fluid because the measurement point is inserted into the fluid, and may affect the measurement results of pressure and flow rate. For this reason, there is a restriction that the thermometer must be installed downstream of the pressure gauge or flow meter. Also, for an electromagnetic flow meter, the flow measurement part must always be filled with fluid, so there are restrictions on the piping route. Also, for a safety valve, if the pressure loss in the wake is too high, in other words, if the piping is too thin or too long, the planned blowing volume cannot be secured, so there are restrictions on the length and diameter of the piping.

[0052] For this reason, the standard system generation unit 321 may have a function of determining the appropriateness of the placement of standard parts and their positional relationships with surrounding parts, taking into account the constraints as described above, and displaying standard parts that require change or should be changed in different colors according to their importance in the standard system configuration diagram. In this way, by supporting the user in changing the positions of standard parts, it is possible to contribute to preventing malfunctions and reducing the number of man-hours required for consideration.

[0053] The standard system generation unit 321 may also have a function of proposing changes to standard parts, such as proposing that the dimensions of a flange joint do not match, but that the dimensions will fall within a specified range if the flange joint is changed to a welded joint.

[0054] Furthermore, the standard system generation unit 321 may have a function of visually proposing an improvement plan for a piping route that is less expensive or has almost the same price on the current standard system configuration adjustment screen. The user may be allowed to select one or more evaluation axes here, and may be able to select not only price but also delivery time, low pressure loss, suitability, recommendation level, short piping length, and the like. Also, the improvement plan may be visually proposed based on the results of machine learning. This makes it possible to provide the user with an optimal piping route, thereby reducing the user's workload.

[0055] Furthermore, the standard system generation unit 321 may have a function of displaying the predicted result of the change in evaluation of a predetermined evaluation axis around the selected plant part as a different color when the plant part is selected in order to move the position of the plant part. In this way, by visually presenting the destination of the plant part, the user can easily determine the placement of the standard part. Examples of the evaluation axis include possibility of price improvement, no price fluctuation, and concern level of price fluctuation: small, medium, large, etc. Furthermore, if there is an area that cannot be moved based on the instrument specifications, the area may be visually presented.

[0056] Furthermore, the standard system generation unit 321 may have a function of increasing the evaluation of a preset evaluation axis or proposing an improvement plan for the evaluation axis. This can be expected to improve not only the ingenuity that contributes to optimizing the spatial arrangement, but also the improvement by reviewing the specifications of the plant parts. For example, such a proposal can be realized based on past cases or machine learning results accumulated by the purchase support device 1, or typical improvement patterns registered in advance.

[0057] Furthermore, the standard system generation unit 321 may have a function of estimating typical man-hours from the specifications of the joints of each selected standard part and information on the piping route, calculating with a general man-hour unit price, estimating construction costs, and displaying the total together with the price of arranging the system. Furthermore, the estimated man-hours may be one of the evaluation axes. In this way, by preparing an evaluation axis including the construction cost, it is possible to contribute to reducing the total cost when the user introduces the system.

[0058] [Standard system memory unit 42] The standard system storage unit 42 stores information based on a standard system configuration diagram determined by a user. FIG. 19 is a diagram showing an example of information stored in the standard system storage unit 42. As shown in FIG. 19, the standard system storage unit 42 stores information on each standard part constituting a fluid transport system in a list in order of connection from top to bottom. The information on each standard part may include a block name, a standard part name, a pipe nominal diameter (dimension), a nominal pressure (temperature and pressure rating), a coordinate of a start point, a coordinate of an end point, and a length. This information is created based on representative specification information of each standard part stored in the standard part database 21. The standard system storage unit 42 may further store a reference delivery date, a reference price, and the like in association with each other. In this manner, the standard system storage unit 42 registers information (dimensions (nominal diameter), nominal pressure (temperature and pressure rating), coordinate information, etc.) necessary for the subsequent process of part selection in an associated manner.

[0059] [Standard system selection section 322] The standard system selection unit 322 selects multiple standard parts with different specifications for major standard parts that are preset among the standard parts stored in the standard system storage unit 42, and generates multiple standard system configuration candidates. Examples of major standard parts include pumps and piping.

[0060] Furthermore, the standard system selection unit 322 acquires calculation blocks corresponding to standard parts, which are components of each of the multiple standard system configuration candidates, from the fluid calculation block database 24, and generates a calculation block chain by connecting the acquired calculation blocks according to the connection order. Then, the standard system selection unit 322 calculates the outlet conditions of the fluid transport system, such as the outlet conditions of the pressure, temperature, and flow rate, by providing input conditions, such as inlet conditions of the pressure, temperature, and flow rate, to the calculation block chain.

[0061] An example of a calculation block chain is shown in Fig. 20. In Fig. 20, for example, "Piping" indicates a standard piping calculation block, "Bv" indicates a standard ball valve calculation block, "Tpiece" indicates a standard T-piece calculation block, "Pump" indicates a standard pump calculation block (including a reducer for adjusting the aperture), "FT" indicates a standard flow meter calculation block, and "Elbow" indicates a standard elbow calculation block.

[0062] The standard system selection unit 322 inputs the input conditions of the fluid, specifically, pressure, temperature, and flow rate, to the first calculation block BL1 of the calculation block chain. The outlet conditions calculated in the first calculation block BL1 are given as input conditions to the next calculation block BL2. Then, the calculation of the outlet conditions is performed sequentially in the order in which the calculation blocks are connected, and the output conditions are finally calculated in the calculation block BLn, which is the final end point. This output condition becomes the outlet condition of the entire system in the standard system configuration candidate. Note that, although the temperature, flow rate, and pressure are input as the inlet conditions, it is also possible to assume that the temperature and flow rate are constant from the inlet to the outlet and calculate only the pressure loss. The standard system selection unit 322 generates a calculation block chain for each of a plurality of standard system configuration candidates, and calculates the outlet conditions of each fluid transport system.

[0063] In addition, the standard system selection unit 322 may have other calculation functions, such as a fluid flow diagnosis function at the highest point, an NPSH (Net Positive Suction Head) calculation function, a hammer diagnosis function, a noise calculation function, and a validity diagnosis function for the design pressure temperature of each component. The fluid flow diagnosis function at the highest point identifies the coordinate information of the highest point of the fluid transport system and the component from the coordinate information of each standard component, and determines whether the pressure conditions of the inlet condition and the outlet condition in the calculation block corresponding to the component are equal to or higher than a predetermined threshold. This makes it possible to confirm whether a flow rate equal to or higher than the minimum flow rate can be ensured in the component at the highest point when transporting a fluid using the selected standard component. In addition, if it is determined that the minimum flow rate cannot be ensured, for example, the specifications of the pump in the standard system configuration candidate may be changed so that the minimum flow rate can be ensured in the component at the highest point.

[0064] In addition, the NPSH calculation function determines whether or not the constraints on the suction side of the pump or compressor are met, the noise calculation function determines whether or not the noise is below a specified threshold, and the hammer diagnosis function determines whether or not there is a possibility of the hammer phenomenon (water hammer phenomenon) occurring. In addition, the function of diagnosing the validity of the design pressure temperature of each component is a function that judges whether the operating pressure temperature of each component is below the design pressure temperature, in other words, whether the operating conditions are within the range of the nominal pressure of each component. For example, when pressure is increased by a pump, the nominal pressure of the plant components downstream of the pump may change depending on the performance of the pump. By diagnosing the validity of the design pressure temperature of each component in consideration of such cases, it is possible to inform the user of the need to select appropriate components, for example, components that can withstand higher pressures. The standard system selection unit 322 generates a standard system selection screen for each standard system configuration candidate, which shows information on the main standard components (pump specifications, flow rate, standard pipe nominal diameter) and the relationship characteristics between flow rate and head (head), and transmits it to the client terminal 70.

[0065] FIG. 21 is a diagram showing 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, nominal standard pipe diameter, and flow velocity for each standard system configuration candidate. In addition, the diagnosis results of each of the above-mentioned calculation functions, for example, the diagnosis result of whether the minimum flow rate can be secured at the highest reach point, the calculation result of NPSH, the hammer risk, the noise level, the validity diagnosis result of the design pressure temperature of each part, etc. may also be displayed as one of the judgment materials. By displaying the diagnostic results from each calculation function in this manner, the user can be provided with information to make decisions based on a variety of perspectives, enabling the user to select a standard system configuration candidate that best suits their needs. Furthermore, the standard system selection screen may also display information such as price and delivery time.

[0066] The standard system selection screen may also display the operating point of the entire system. In Fig. 21, the operating point of the entire system is displayed on a graph (for example, as an intersection of the performance curve and the resistance curve on the Q (flow rate)-H (head) plane). This operating point is calculated taking into account the output conditions of the system calculated in the calculation block chain. In this way, by presenting the operating points and specification information of the entire system to the user, the user can select and procure a set of multiple plant parts that make up the fluid transport system in the same way as selecting each individual plant part. In addition, the user can also consider the configuration of surrounding equipment.

[0067] Furthermore, the standard system selection screen may be provided with an input section for instructing to increase or decrease the flow rate condition and an input section for instructing to increase or decrease the diameter condition of the pipe when the presented standard system configuration candidates do not have the desired one. When these input sections are operated, standard parts are specified again according to the input instructions, multiple standard system configuration candidates are newly generated, and the above-mentioned calculation of the outlet condition and the like is performed for each standard system configuration candidate. On the standard system selection screen, the user selects one of the standard system configuration candidates that meets the user's needs and presses the send button BT2. This causes information on the standard system configuration candidate selected by the user to be sent to the purchase support device 1.

[0068] The standard system selection unit 322 updates the information in the standard system storage unit 42 based on the information of the standard system configuration candidate selected by the user. That is, the various information (such as the names and specification data of the standard parts constituting the fluid transport system) shown in Fig. 19 is updated based on the standard system configuration candidate selected by the user, in other words, the information of the plant parts of the representative specifications selected by the user.

[0069] [Supplier Parts Selection Division 33] The supplier parts selection unit 33 selects, from the supplier parts database 22, supplier parts corresponding to each of the multiple standard parts selected by the standard parts selection unit 32. Specifically, the supplier parts selection unit 33 selects supplier parts corresponding to each standard part stored in the standard system storage unit 42. The supplier parts selection unit 33 includes, for example, a parts candidate specification unit 331 , a system candidate generation unit 332 , a system adjustment unit 333 , and a specification confirmation unit 334 .

[0070] [Part candidate identification unit 331] The part candidate identifying unit 331 identifies one or more supplier parts corresponding to each standard part constituting the standard system configuration diagram from the supplier part database 22. Specifically, the part candidate identifying unit 331 identifies supplier parts corresponding to each standard part stored in the standard system storage unit 42 from the supplier part database 22. At this time, it is preferable that the part candidate identifying unit 331 identifies multiple supplier parts sold by different suppliers as part candidates for each standard part. More specifically, for each standard part, the part candidate identification unit 331 identifies multiple supplier parts that meet the conditions based on the standard part name and specification data (e.g., design pressure, design temperature, nominal diameter, etc.) as part candidates, and obtains the price, delivery date, and option information of the supplier parts from the supplier part database 22. For example, in the case of a valve, a supplier part is selected based on the nominal pressure and size (e.g., nominal diameter).

[0071] Here, some suppliers may require unique requirements when selecting supplier parts, and in this case, it is necessary to inquire about the information from the user. In such a case, the part candidate specification unit 331 may inquire about additional input from the user by displaying an input form or the like for inputting the necessary information on the client terminal 70.

[0072] In this way, when the part candidate identification unit 331 identifies one or more supplier parts (e.g., supplier parts from companies A, B, C, etc.) corresponding to each standard part such as a pipe, a ball valve, a pump, etc., it stores information on the identified supplier parts in the part candidate storage unit 43 in association with each standard part.

[0073] [Part candidate storage unit 43] The part candidate storage unit 43 stores information on supplier parts in association with each block constituting the standard system configuration diagram. Fig. 22 is a diagram showing an example of data stored in the part candidate storage unit 43. As shown in Fig. 22, the part candidate storage unit 43 stores the supplier, model number, product name, specification information, price and delivery date information in association with the component (block name). Here, the supplier, model number, product name, specification information, price and delivery date information can be written by writing the information obtained from the supplier part database 22 (see Fig. 5).

[0074] [System Candidate Generation Unit 332] The system candidate generating unit 332 generates at least one system configuration candidate, which is a combination of supplier parts that configure a fluid transport system, based on a plurality of supplier parts stored in the part candidate storage unit 43, and displays the system configuration candidate on the client terminal 70. Specifically, the system candidate generation unit 332 generates multiple system configuration candidates according to a predetermined evaluation criterion from multiple supplier parts stored in the part candidate storage unit 43. Examples of the evaluation criterion include the lowest price, shortest delivery time, low price and short delivery time, and recommendation.

[0075] The lowest price is a candidate combination of supplier parts with the lowest total price of the plant parts constituting the fluid transport system, and the shortest delivery time is a combination of supplier parts with the shortest delivery time of the plant parts constituting the fluid transport system. The low price and short delivery time are evaluated from both the price and delivery time, and are, for example, the combination of supplier parts with the highest evaluation value obtained by substituting the respective values ​​of the price and delivery time into an evaluation calculation formula including the price and delivery time as parameters. The recommendation is, for example, the combination of parts with the highest overall evaluation value obtained by adding other evaluation indexes in addition to the price and delivery time. For example, the evaluation values ​​of the price, delivery time, and word-of-mouth (past evaluation information by users) are substituted into a predetermined evaluation value calculation formula to calculate an overall evaluation value for each supplier part, and the combination of supplier parts with the highest calculated overall evaluation value is identified.

[0076] The evaluation value calculation formula can be set arbitrarily. For example, each item may be evaluated on a scale of 10 points and the values ​​may be added together, or a weighting factor may be set for each item and the scores for each item may be multiplied by the weighting factor and the value may be added together. Also, machine learning may be performed using the past performance of the operator of the purchase support device 1, past performance of similar designs, or past performance of the operation of the purchase support device 1, and the items may be displayed in order of recommendation from those closest to the machine learning result.

[0077] When the system candidate generating unit 332 generates a plurality of system configuration candidates based on each evaluation criterion, it generates a comparison and selection screen on which these candidates are displayed so as to be compared, and transmits the same to the client terminal 70.

[0078] Fig. 23 is a diagram showing an example of a comparison and selection screen. In the comparison and selection screen shown in Fig. 23, the system configuration candidate with the lowest price is displayed as pattern 1, the system configuration candidate with the shortest delivery time is displayed as pattern 2, the system configuration candidate evaluated from the viewpoints of both low price and short delivery time is displayed as pattern 3, and the recommended system configuration candidate is displayed as pattern 4. In addition, for each system configuration candidate, the supplier, product name, price, delivery time, and user evaluation of each plant part are displayed. In Fig. 23, piping, ball valves, and pumps are displayed as examples of plant parts. In this comparison and selection screen, the user can select a desired pattern.

[0079] The comparison and selection screen also has an individual selection button BT3. This individual selection button BT3 is a button for transitioning to an individual selection screen where the user can select each plant part. FIG. 24 shows an example of the individual selection screen. In the individual selection screen, information on supplier parts is displayed for each component that makes up the fluid transport system, in other words, for each block shown in the standard system configuration diagram. In addition, each supplier part can be displayed in order of price, delivery date, or recommendation. The display order can be changed by switching tabs.

[0080] Once the user has selected one of the system configuration candidates on the comparison selection screen, or has identified the supplier parts for each component that makes up the fluid transport system on the individual selection screen, the user presses the confirm button BT4 (see Figure 23). As a result, information on the supplier parts corresponding to each component selected by the user is transmitted to the purchase support device 1. The information on the supplier parts selected by the user in this manner is stored in the selected parts storage unit 44 in association with the information on each component.

[0081] [Selected parts storage unit 44] The selected parts storage unit 44 stores information on supplier parts corresponding to each of the components constituting the fluid transport system. Furthermore, the selected parts storage unit 44 stores coordinate information corresponding to each supplier part. FIG. 25 is a diagram showing an example of data stored in the selected parts storage unit 44. As shown in FIG. 25, the selected parts storage unit 44 registers information on supplier parts corresponding to each plant part in association with coordinate information. The supplier part information is information acquired from the part candidate storage unit 43, for example, and the coordinate information is information acquired from the standard system storage unit 42. In addition, in the selected parts storage unit 44, the supplier parts may be stored in a list in the order in which the plant parts are arranged from the transfer start point to the transfer end point in the system configuration diagram shown in FIG.

[0082] [System Adjustment Section 333] The system adjustment unit 333 generates a system configuration diagram connecting the start point of conveyance to the end point of conveyance based on the supplier part information and coordinate information stored in the selected part storage unit 44, generates a system configuration adjustment screen including the generated system configuration diagram, and displays this screen data on the client terminal 70. FIG. 26 shows an example of the system configuration adjustment screen. As shown in FIG. 26, the system configuration adjustment screen displays detailed information on the selected parts together with the system configuration diagram generated using the supplier parts. The system configuration diagram shown in FIG. 26 includes parts for piping adjustment (modification parts). This shows the piping error caused by adopting supplier parts instead of standard parts.

[0083] That is, the standard system configuration diagram shown in FIG. 18 is created using standard parts, whereas the system configuration diagram shown in FIG. 26 is created using supplier parts. Therefore, due to an error between the typical specifications of the standard parts and the specifications of the supplier parts, the position of the transfer end point may differ from the coordinates of the transfer end point requested by the user. Therefore, the error is shown in the system configuration diagram as a piping adjustment part, and the user is prompted to adjust the position of each component part (pump, etc.) and the length of the piping so that the piping adjustment part is not required. This makes it possible to eliminate the error that occurs when using supplier parts, and to satisfy the conditions of the transfer start point and transfer end point entered on the request input screen (see FIG. 9). When the user finishes the adjustment, he or she presses the send button BT5. This causes information about the adjusted system configuration diagram, specifically, the adjusted coordinate information and length of each component, to be sent to the purchase support device 1. When the system adjustment unit 333 receives the adjusted information, it updates the coordinate information and length of each component stored in the selected component storage unit 44 based on this information.

[0084] [Specification confirmation section 334] The specification checking unit 334 performs a new performance calculation based on the data of the adjusted system configuration diagram, i.e., the updated data stored in the selected part storage unit 44. For example, the specification checking unit 334 acquires a calculation block corresponding to each supplier part stored in the selected part storage unit 44 from among a plurality of calculation blocks stored in the fluid calculation block database 24, and connects the acquired calculation blocks based on the arrangement order to generate a calculation block chain. Then, the specification checking unit 334 calculates the outlet condition (e.g., pressure, temperature, flow rate) of the fluid transport system by giving input conditions (e.g., pressure, temperature, flow rate) to the created calculation block chain. In addition, the specification checking unit 334 may have other calculation functions such as a fluid flow diagnosis function at the highest point, a NPSH calculation function, a hammer diagnosis function, a noise calculation function, and a validity diagnosis result of the design pressure temperature of each part.

[0085] When the performance calculation is completed, the specification confirmation unit 334 generates a final confirmation screen including the performance calculation results and the like, 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. FIG. 27 is a diagram showing an example of a final confirmation screen. The final confirmation screen displays the operating point when the fluid conveying system is configured using selected parts (supplier parts selected by the user). Specifically, the final confirmation screen displays the pump model, flow rate, nominal pipe diameter, and flow velocity. In addition, the diagnosis results by each of the above-mentioned calculation functions, for example, the diagnosis result of whether the minimum flow rate can be secured at the highest reach point, the NPSH, the hammer risk, the noise level, the validity diagnosis result of the design pressure temperature of each part, and the like, may also be displayed. Furthermore, the final confirmation screen displays the price and delivery date information as well as detailed information of the selected parts (for example, the supplier, model number, product name, price, quantity, etc.). When the user presses the confirmation button BT6, the selection of the various plant parts constituting the fluid transport system is confirmed and the order reservation is completed. In this way, information on the finally selected supplier parts is stored in the order database 25 as order reservation information.

[0086] [Electrical component extraction unit 34] The electrical-related part extraction unit 34 extracts supplier parts (plant parts) selected by the supplier part selection unit 33, i.e., supplier parts (hereinafter, for convenience, referred to as "electrical-related parts") that need to be connected to electrical equipment based on the specification data of the supplier parts stored in the selected part storage unit 44. For example, the electrical-related part extraction unit 34 may extract, as electrical-related parts, supplier parts whose specification data includes data related to electricity, such as the type of power source (DC power source or AC power source), required voltage, required current, and number of phases (single-phase or three-phase in AC power source). In addition, the specification data may include information (e.g., an electrical-related flag, etc.) for determining whether the part is an electrical-related part, and the electrical-related part extraction unit 34 may determine whether the part is an electrical-related part based on this information.

[0087] [Electrical component specification section 35] The electrical component identification unit 35 identifies, from the electrical component database 23, electrical components required for connecting each electrical component to the electrical equipment, based on the specification data of the electrical components. For example, in the supplier parts database 22, for electrical-related parts, information such as the type of power source (DC power source or AC power source), required voltage, required current, number of phases (single-phase or three-phase AC power source), number of electrical connections, etc. is registered as specification data. Also, in the supplier parts database 22, information on electrical equipment required for connecting an electrical system is registered in advance for electrical-related parts. For example, the electrical component identification unit 35 identifies electrical equipment matching the specifications from the electrical component database 23 based on the specification data and information on the electrical equipment stored in the supplier parts database 22. Also, the electrical component identification unit 35 may identify multiple part candidates when there are multiple part candidates as electrical parts, in other words, when there are multiple part candidates matching the specification data of the electrical-related parts.

[0088] In addition, the thickness of a cable, which is one of the electrical components, needs to be adjusted depending on the current and the length of the cable. For example, if a thin cable is mistakenly selected when the distance between an electrical component and an electrical facility (e.g., a power source) is long, a voltage drop may occur, and the necessary voltage may not be supplied to the electrical component. For this reason, when selecting a cable, a function may be provided that queries the user about the distance between the electrical component and the power source, and a cable with an appropriate diameter may be selected according to the input distance.

[0089] [Electrical system generation unit 36] The electrical system generation unit 36 ​​causes the client terminal 70 to display information on the electrical components identified by the electrical component identification unit 35. Specifically, the electrical system generation unit 36 ​​creates an electrical system diagram in which electrically-related components and a power source are connected by the electrical components identified by the electrical component identification unit 35, and causes the client terminal 70 to display the created electrical system diagram.

[0090] An example of an electrical system diagram is shown in Figure 28. In Figure 28, an electrical system diagram is shown in which a flow transmitter, a temperature transmitter, a valve positioner that controls the valve opening of a control valve, and a pump drive motor that drives a pump are extracted as electrical components. Each of these electrical components is connected to a power source via electrical components (e.g., communication cables, power cables, breakers, fuses, AI modules, AO modules, DI modules, DO modules, I / O systems, etc.).

[0091] The electrical components included in this electrical system diagram are configured so that the user can specify, for example, electrical components installed in existing equipment. When the user specifies an electrical component in this electrical system diagram, the electrical system generation unit 36 ​​changes the display mode (for example, changing the color, changing the line type, blinking, etc.) of the electrical component specified by the user. This allows the user to intuitively grasp the electrical components that must be newly purchased when purchasing the current fluid transport system. Furthermore, by having the user perform the task of checking whether each electrical component is installed in the existing electrical equipment, it is possible for the user to perform a thorough check task.

[0092] Here, the user specifies the existing electrical components, but this is not limited to the above. For example, a field for allowing the user to input or select the existing electrical equipment may be provided on the condition input screen by the condition input support unit 31, and the user may input information on the existing electrical equipment in advance. In this case, information on the electrical components arranged in the existing equipment is registered in the selection condition storage unit 41. Therefore, the existing electrical components may be displayed on the electrical system diagram based on the information on the existing electrical components stored in the selection condition storage unit 41. At this time, the electrical system generation unit 36 ​​may display the electrical components provided in the existing electrical equipment and the electrical components that need to be newly purchased in a distinguishable manner on the electrical system diagram. For example, a display mode such as changing the color, changing the line type, or blinking may be used. In this way, by presenting the user with an electrical system diagram, the user can intuitively and thoroughly check whether the electrical connections between the existing electrical equipment and the system to be arranged are consistent.

[0093] In addition, when information on existing electrical equipment is stored in the selection condition storage unit 41, the electrical system generation unit 36 ​​may display existing electrical components unrelated to the electrical-related components in the electrical system diagram, for example, as illustrated in FIG. 29. In this case, the electrical system generation unit 36 ​​may display existing electrical components related to the electrical-related components and existing electrical components unrelated to the electrical-related components in different display modes. Note that, as an example, in FIG. 29, electrical components unrelated to the electrical-related components are shown by dotted lines. In this way, by including electrical components other than those required to connect the electrical-related components to a power source in the electrical system diagram, it is possible to grasp the overall picture of the electrical equipment.

[0094] Furthermore, when a plurality of part candidates are identified by the electric component identification unit 35, in other words, when a plurality of part candidates exist as electric components, when a user designates any electric component in the electric system diagram, the electric system generation unit 36 ​​may display the part candidates of the designated electric component in a selectable manner, thereby allowing the user to select a desired electric component from the plurality of part candidates.

[0095] Although only the electrical system diagram is displayed on the screens shown in Figures 28 and 29, when the user specifies any electrical component on this electrical system diagram, the electrical system generation unit 36 ​​may display details of the electrical component specified by the user (e.g., specifications, delivery date, price, etc.) on the display screen of the client terminal 70 (as a pop-up on the electrical system diagram or by transitioning to another screen).

[0096] Further, the electrical system diagram may be provided with a display switching button BT7 for switching the display mode. For example, when the display switching button BT7 is operated by the user, the electrical system generating unit 36 ​​may draw wiring routes connecting electrical-related components and electrical equipment in a three-dimensional system configuration diagram such as an isometric view using an isometric projection or a 3D display, as shown in Fig. 30, and cause the client terminal 70 to display the system configuration diagram including the wiring routes. This allows the user to confirm the wiring route of the cable in relation to other supplier parts that configure the fluid transport system. Furthermore, this system configuration diagram is configured so that the user can change the cable wiring route. This allows the user to consider and change the cable wiring route while visually checking the connection with peripheral devices. Also, if the cable wiring route is changed, it is possible to calculate the distance based on the changed wiring route, making it possible to select a cable with an appropriate diameter (thickness) according to the distance.

[0097] The user checks the electrical system diagram and the system configuration diagram, and when the user has completed checking the electrical components to be purchased by making any necessary changes, etc., he or she presses the Confirm button BT8 (see FIGS. 28 and 29). This causes information about the electrical components confirmed by the user to be sent to the purchase support device 1.

[0098] In addition, with regard to electrical components, it may be preferable for multiple designers to check, such as a mechanical designer who selects plant components and an electrical designer in charge of electrical equipment. In such cases, the identification numbers of the designers who will check may be registered in advance, and an order reservation may be made when the Confirm button BT8 is pressed by all registered designers. In this way, an order reservation is made only after an agreement is reached between the mechanical designer and the electrical designer, so that the risk of the two having different opinions after the order is placed can be avoided.

[0099] [Order Support Department 37] The ordering support unit 37 supports ordering of supplier parts and electrical parts that have been finally confirmed. First, the order support unit 37 stores information on supplier parts and electrical parts that have been finally confirmed by the user in the order database 25 as order reservation information. The order database 25 stores information on orders for each user. Information on orders includes order reservation information, order history, order status, etc. The order reservation information includes data on supplier parts (see FIG. 25) and electrical parts stored in the selected parts storage unit 44.

[0100] Next, the order support unit 37 generates an order reservation screen based on the order reservation information for the fluid transport system stored in the order database 25, and displays it on the client terminal . The order reservation screen displays the price and delivery date of the fluid transport system, and the order reservation date. The order reservation screen may also display various functions for supporting the user in ordering the system. FIG. 31 is a diagram showing an example of the order reservation screen. The order reservation screen shown in FIG. 31 displays quotation confirmation, specification confirmation, and quotation update as examples of functions for supporting the system ordering.

[0101] When the user presses the order button BT9 on the order reservation screen, order instruction information instructing an order is sent to the purchase support device 1. Upon receiving the order instruction information, the order support unit 37 places an order for the supplier parts with each supplier terminal 80 (see FIG. 1) based on the order reservation information, and changes the order reservation information to order completion information.

[0102] Next, a purchase support method according to this embodiment will be briefly described with reference to Fig. 32. A series of processes shown below is stored as a program (e.g., a purchase support program) in the auxiliary storage device 12 provided in the purchase support device 1, and is realized by the CPU 11 reading this program into the main memory 13 and executing it.

[0103] 32 is a flowchart showing an example of a processing procedure of the purchase support method according to the present embodiment. For convenience of explanation, the purchase support method will be described below in relation to a case where a user wishes to purchase a fluid transport system that transports water from one tank to another.

[0104] First, the purchase support device 1 transmits an interactive condition input screen such as that shown in Fig. 6 to Fig. 17 to the client terminal 70 and displays it, thereby allowing the user to input various information required for purchasing plant parts for a fluid transport system (SA1: condition input support step). The information input in the condition input support step is stored in the selection condition storage unit 41 as selection conditions.

[0105] Next, the purchase support device 1 identifies standard parts constituting the fluid transport system based on the selection conditions, and generates a standard system configuration diagram based on the identified standard parts. Then, the standard system configuration diagram is presented to the user, allowing the user to adjust the standard system configuration (SA2: standard system generation process). Specifically, the purchase support device 1 acquires standard parts constituting the fluid transport system from the standard parts database 21 based on the selection conditions stored in the selection condition storage unit 41, and generates a standard system configuration diagram by sequentially arranging the standard parts on a piping route connecting the transport start point to the transport end point. Then, a standard system configuration adjustment screen (see FIG. 18) including the standard system configuration diagram is displayed on the display unit of the client terminal 70, and the user adjusts the standard system configuration diagram. Information based on the standard system configuration diagram confirmed by the user is stored in the standard system storage unit 42 (see FIG. 19).

[0106] Next, the purchase support device 1 generates a plurality of standard system configuration candidates, generates a standard system selection screen that displays these candidates in a comparative manner (see FIG. 21), and allows the user to select the desired standard system configuration candidate (SA3: standard system selection step). At this time, the purchase support device 1 may generate a calculation block chain for each standard system configuration candidate, calculate the exit conditions of the system, and display the exit conditions on the standard system selection screen. When any of the standard system configuration candidates is selected by the user, the purchase support device 1 updates the information in the standard system storage unit 42 based on the information of the selected standard system configuration candidate.

[0107] Next, the purchasing support device 1 identifies one or more supplier parts corresponding to each standard part stored in the standard system memory unit 42 from the supplier parts database 22, and stores information on the identified supplier parts in the part candidate memory unit 43 in association with each standard part (SA4: part candidate identification process).

[0108] Next, the purchase support device 1 generates multiple system configuration candidates from multiple supplier parts stored in the part candidate storage unit 43 according to a predetermined evaluation criterion, generates a comparison selection screen that displays these candidates for comparison (see FIG. 23), and allows the user to select a desired selection pattern candidate (SA5: system candidate generation step). When the user selects one of the system configuration candidates, the purchase support device 1 stores information about the selected system configuration candidate together with coordinate information in the selected part storage unit 44.

[0109] Next, the purchase support device 1 generates a system configuration diagram connecting the transport start point to the transport end point based on the supplier part information and coordinate information stored in the selected parts storage unit 44, generates a system configuration adjustment screen including the generated system configuration diagram (see FIG. 26), and allows the user to adjust the system configuration (SA6: system adjustment step). When the system configuration is adjusted by the user, the purchase support device 1 updates the information in the selected parts storage unit 44 based on the adjusted system configuration.

[0110] Next, purchase support device 1 performs performance calculations based on the adjusted system configuration diagram, and generates a final confirmation screen (see FIG. 27) including the performance calculation results, etc., and asks the user to confirm it (SA7: specification confirmation step). Once the user has confirmed the order reservation, purchase support device 1 stores information about the supplier parts that have been finally confirmed in order database 25 as order reservation information.

[0111] Next, the purchase support device 1 extracts supplier parts that need to be connected to electrical equipment as electrical-related parts based on the specification data of multiple supplier parts stored in the selected parts storage unit 44 (SA8: electrical-related part extraction step). Next, the purchase support device 1 identifies electrical components necessary for connecting the electrical-related components to the electrical equipment based on the specification data of the electrical-related components (SA9: electrical component identification step), and causes the client terminal to display information on the identified electrical components (SA10: electrical system generation step). As a result, for example, electrical system diagrams such as those shown in Figs. 28-29 and system configuration diagrams such as those shown in Fig. 30 are displayed on the display screen of the client terminal 70. On this display screen, the user changes and adjusts the electrical components, and when the final electrical components are finalized, the purchase support device 1 stores information on the finalized electrical components (for example, supplier, identification number, specification information, etc.) in the selected parts storage unit 44 in association with the plant parts, and also additionally registers the information in the order reservation information stored in the order database 25.

[0112] Next, the purchase support device 1 generates an order reservation screen based on the order reservation information (information on the selected supplier parts and information on the electrical parts) of the fluid transport system stored in the order database 25, and provides it to the user (SA11: order support step). Then, when the purchase support device 1 receives an order instruction from the user, it places orders for supplier parts with each supplier based on the order reservation information, and changes the order reservation information to order completion information.

[0113] As described above, the purchasing support device 1, purchasing support method, and purchasing support program of this embodiment select a plurality of plant parts that constitute a fluid transport system, and based on the specification data of the selected plurality of plant parts, extract plant parts that require connection to electrical equipment as electrical-related parts, identify electrical parts required to connect the electrical-related parts to the electrical equipment based on the specification data of the extracted electrical-related parts, and display information on the identified electrical parts on the client terminal. This makes it easy to select the plant components that make up the fluid transport system, as well as the electrical components required for electrical connections, making it easy to order the entire system, including the electrical components.

[0114] According to this embodiment, the user simply performs the simple operation of inputting the selection conditions to identify a plurality of standard parts that meet the selection conditions, and a standard system configuration diagram consisting of the identified plurality of standard parts is generated. Then, one or a plurality of supplier parts corresponding to each of the standard parts that constitute the standard system configuration diagram are selected, and at least one system configuration candidate that is a combination of supplier parts that constitute a fluid transport system based on the selected plurality of supplier parts is generated and presented to the user as a selection candidate.

[0115] For example, when selecting plant parts, the selection criteria and calculation formulas may differ for each supplier, and if calculations are performed for each supplier at once, the amount of calculations becomes enormous, and it may take a long time to consider specifications and estimates. In contrast, according to the purchasing support device 1 of this embodiment, in the first step, a standard system configuration diagram is generated using standard parts that meet the selection conditions, and in the second step, each supplier part corresponding to each standard part is identified. This makes it possible to narrow down the supplier parts, so that the amount of calculations can be minimized while taking into account the needs of the user, and processing time can be shortened. In addition, the user can easily select multiple plant parts that make up the fluid transport system at once by selecting the desired system configuration candidates from those presented as selection candidates. This makes it possible to arrange for multiple plant parts easily and efficiently. Therefore, it is possible to effectively shorten the period from inputting the conditions to purchasing.

[0116] Although 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 modifications or improvements can be made to the above embodiments without departing from the gist of the disclosure, and the forms with such modifications or improvements are also included in the technical scope of the present disclosure. Furthermore, the processing flow described in the above embodiment is also one example, and unnecessary steps may be deleted, new steps may be added, or the processing order may be rearranged, without departing from the spirit of the present disclosure.

[0117] For example, in the above embodiment, after a supplier part is selected, an electrical part corresponding to the selected supplier part is identified, but this is not limited to the above. For example, when a standard part is selected by the standard parts selection unit 32, an electrical part corresponding to the selected standard part may be identified.

[0118] In the above-described embodiment, the electrical components are identified after the system configuration of the plant components is adjusted, but this is not limited to the above. For example, the standard system configuration adjustment screen (see FIG. 18) and the system configuration adjustment screen (see FIG. 26) may be configured to display the wiring routes of the electrical devices together, so that the wiring routes of the electrical components can be adjusted simultaneously along with the piping routes. This allows the user to design a system by taking into consideration both the layout and piping routes of the plant devices and the wiring routes of the electrical components. This can improve the efficiency of the system design.

[0119] In the above embodiment, the case of selecting electrical parts has been described, but in addition to this, the configuration may be such that instrumentation piping can be selected and ordered. In this case, for example, the purchase support device includes an instrumentation-related part extraction unit that extracts plant parts that require instrumentation piping as instrumentation piping-related parts from among a plurality of plant parts selected by the standard part selection unit 32 or the supplier part selection unit 33, an instrumentation piping part identification unit that identifies instrumentation piping parts (e.g., pipes, joints, valves, etc.) for connecting the instrumentation piping-related parts to the process connection part based on the specification data of the instrumentation piping-related parts (e.g., process connection port, mounting direction of the meter, information on the fluid to be measured, etc.), and an instrumentation piping configuration generation unit that displays information on the identified instrumentation piping parts on the client terminal. Note that the instrumentation piping includes, for example, a pipe that conveys instrumentation air that transmits a command value for operating an air-operated valve or cylinder. In this case, the fluid flowing through the instrumentation piping is dehumidified instrumentation air. Fluids used in the actuator that receives the command value and actually drives the valve body or cylinder include dehumidified instrument air, hydraulic oil, inert gas, etc. Cable protection pipes (electrical conduits) for protecting cables are also examples of instrumentation piping.

[0120] In the above embodiment, the standard parts are identified first, and then the supplier parts corresponding to the standard parts are identified, but this is not limited to the above. For example, the purchase support device 1 does not need to have all the functions shown in Fig. 3, and some functions can be omitted. For example, the standard parts selection unit 32 may be omitted, and the supplier parts selection unit 33 may select supplier parts that meet the selection conditions.

[0121] It is not necessary to execute all of the series of processes shown in Fig. 32, and some of the processes can be omitted. For example, the standard system generation process (SA2) and the standard system selection process (SA3) can be omitted, and supplier parts that meet the selection conditions can be selected in the part candidate identification process (SA4).

[0122] In addition, in this embodiment, the purchase support device 1 may be configured to be capable of planning and arranging for insulation based on the selection result of the plant parts. When selecting insulation, for example, the temperature of the outermost surface of the insulation may be calculated from parameters such as the specifications of the insulation material itself (thickness, thermal conductivity, etc.), the temperature of the inner surface of the insulation ≒ the temperature of the fluid, the surrounding temperature, and the surface heat transfer coefficient (e.g., whether there is no wind or wind, etc.), and the temperature may be selected so that it is equal to or lower than a threshold value (safe insulation). In addition, by multiplying this by the flow rate or flow speed of the fluid, the amount of heat dissipated from the system per unit time may be calculated and selected so that it is equal to or lower than a threshold value (process insulation). Conventionally, it was necessary to extract the relevant information from a drawing summarizing the results of the consideration of the operating conditions of the system and perform the calculations individually (and generally, the consideration is across departments), which was time-consuming. In addition, there were cases where selection errors occurred due to incorrect data transfer. In contrast, the purchase support device 1 according to this embodiment allows the selection of insulation to be made in a single go by simply linking the conditions, thereby reducing the burden on the user. It is also possible to prevent selection errors. The purchase support device 1 may be configured to create an order specification for warming arrangements and to purchase based on the results of the selection.
