[0012] A price determination system, a price determination method, and a program to which the present invention is applied will be described below with reference to the accompanying drawings. Note that the scope of the present disclosure is not limited to the following embodiments, and can be modified as desired within the scope of the technical concept of the present disclosure.

[0013] (First embodiment) First, a price determination system, a price determination method, and a program according to a first embodiment will be described.

[0014] 1 is a block diagram showing an example of a pricing system 100 according to a first embodiment. The pricing system 100 is connected to an equipment manufacturer system 200 and an equipment management company system 300 via, for example, a communication network. The pricing system 100, the equipment manufacturer system 200, and the equipment management company system 300 each have a communication interface (not shown) such as a network interface card (NIC) or a wireless communication module for connecting to a communication network NW such as the Internet. The communication network NW may include, for example, a general-purpose network such as the Internet, and a private network such as local 5G or Wi-Fi (registered trademark).

[0015] The pricing system 100 includes an information processing device that performs processing to determine the price of a product traded between an equipment manufacturer and an equipment management company. In the embodiment, the product is, for example, a device included in the equipment and a part of the device. For example, the equipment is a power generation facility, the device is a generator, and the part is a bearing or the like.

[0016] The equipment manufacturer system 200 includes an information processing device managed by an equipment manufacturer that manufactures the equipment included in the equipment and the parts of the equipment. The equipment manufacturer system 200 includes, for example, manufacturing equipment for the equipment and parts, a database device that manages equipment information and part information, a terminal device operated by the equipment manufacturer, and a communication device that communicates via a communication network.

[0017] The facility management company system 300 includes information processing devices managed by a facility management company that operates the facility. The facility management company system 300 includes, for example, a facility control device, a database device that manages the operating status of the facility, a terminal device operated by the facility management company, and a communication device that communicates via a communication network.

[0018] For example, the pricing system 100 receives product information, desired delivery date information, and desired quantity information from the facility management company system 300. The pricing system 100 determines a price for manufacturing the desired quantity of the product indicated in the product information by the desired delivery date, and transmits price information indicating the determined price to the facility management company system 300. The equipment management company can refer to the price information received from the price determination system 100. This allows the equipment management company to consider whether to place an order for the product with the equipment manufacturer system 200, referring to the price information.

[0019] FIG. 2 is a block diagram showing an example of the configuration of the price determination system 100 according to the first embodiment. The price determination system 100 includes, for example, an acquisition unit 102, an inventory management unit 104, a coefficient determination unit 106, a price determination unit 108, an output unit 110, and a memory unit 112. The acquisition unit 102, the inventory management unit 104, the coefficient determination unit 106, the price determination unit 108, and the output unit 110 are functional units realized by a processor such as a CPU (Central Processing Unit) executing a program stored in a program memory. The memory unit 112 is a storage device such as a memory. The memory unit 112 may be an external storage device connected to the price determination system 100, such as a database server.

[0020] The acquisition unit 102 acquires the desired delivery date and desired quantity of a product that the facility management company wishes to purchase. The acquisition unit 102 acquires, for example, information that is a set of product information, desired delivery date information, and desired quantity information from the facility management company system 300. The product information is information that identifies a product.

[0021] The inventory management unit 104 acquires inventory quantity information from, for example, the equipment manufacturer system 200 . The inventory management unit 104 calculates the trend of fluctuations in the inventory rate, which indicates the ratio of the quantity of inventory items to a predetermined set value, for each product. The predetermined set value is information indicating the standard inventory quantity for the product. The set value may be, for example, the quantity to be used up in one year, or the average inventory quantity of the product over the past year. The inventory management unit 104 obtains inventory quantity information indicating the quantity of inventory items in the equipment manufacturer system 200, for example, and calculates the ratio to the set value to calculate the current inventory rate.

[0022] The inventory management unit 104 calculates the trend of fluctuations in the inventory rate based on the past and current inventory rates. The trend of fluctuations in the inventory rate may be, for example, an increase, decrease, or a flat trend. The trend of fluctuations in the inventory rate may change due to, for example, the season, large-scale equipment upgrades or construction work, emergencies such as disasters, etc.

[0023] The coefficient determination unit 106 determines a first coefficient, which is a coefficient for increasing or decreasing the sales price of a product depending on the length of the delivery date, based on the desired delivery date acquired by the acquisition unit 102. The shorter the delivery date, the larger the first coefficient determined by the coefficient determination unit 106. As a result, the coefficient determination unit 106 increases the sales price when the desired delivery date is short. Furthermore, the coefficient determination unit 106 decreases the first coefficient to discount the sales price when the desired delivery date is long. The desired delivery date may be any of predetermined delivery dates selected by the equipment management company, such as urgent, within one week, within two weeks, or within one month.

[0024] The coefficient determination unit 106 determines a second coefficient, which is a coefficient for increasing or decreasing the sales price according to the inventory rate relative to the desired delivery date, based on the tendency of fluctuations in the product inventory rate calculated by the inventory management unit 104. The coefficient determination unit 106 determines a larger value for the second coefficient as the inventory rate decreases, thereby increasing the sales price as the inventory rate decreases.

[0025] The coefficient determination unit 106 increases the sales price when the inventory rate at the desired delivery date is low, but determines a higher second coefficient to further increase the sales price when the fluctuation trend of the inventory rate at the desired delivery date is downward.The coefficient determination unit 106 discounts the sales price when the inventory rate at the desired delivery date is high, but determines a lower second coefficient to further discount the sales price when the fluctuation trend of the inventory rate at the desired delivery date is upward.

[0026] The coefficient determination unit 106 may obtain, for example, the second coefficient when the inventory rate is low and the inventory rate fluctuation trend is downward, the second coefficient when the inventory rate is low and the inventory rate fluctuation trend is flat, the second coefficient when the inventory rate is low and the inventory rate fluctuation trend is upward, the second coefficient when the inventory rate is high and the inventory rate fluctuation trend is downward, the second coefficient when the inventory rate is high and the inventory rate fluctuation trend is flat, and the second coefficient when the inventory rate is high and the inventory rate fluctuation trend is upward by referring to table data or by using a calculation formula.

[0027] The storage unit 112 stores a base price that serves as a basis for the sales price. The base price may be a price set in advance for each product, or may be a calculated value such as an average price over a one-year period.

[0028] The price determination unit 108 determines the selling price based on the desired quantity acquired by the acquisition unit 102, the first coefficient and second coefficient generated by the coefficient determination unit 106, and the basic price stored in the storage unit 112. The price determination unit 108 determines the selling price as the multiplication value of the desired quantity, the first coefficient, the second coefficient, and the basic price, for example.

[0029] The output unit 110 transmits the selling price information to the facility management company system 300. The output unit 110 may transmit the selling price information to a terminal device 310 of the facility management company in the facility management company system 300, for example.

[0030] The output unit 110 may output the sales price and stock rate for the desired delivery date to the terminal device 310 of the equipment management company. This allows the equipment management company to confirm the sales price for the desired delivery date specified by the equipment management company, and further confirm the stock rate for the desired delivery date as the reason for the sales price.

[0031] As described above, the pricing system 100 of the first embodiment determines the first coefficient based on the desired delivery date, determines the second coefficient based on the trend of fluctuations in the inventory rate, and determines the sales price based on the desired quantity, the first coefficient, the second coefficient, and the base price. This allows the pricing system 100 to appropriately determine the price of a product. Furthermore, the pricing system 100 outputs the product price to the facility management company, allowing the facility management company to determine the product price, thereby eliminating the need for the equipment manufacturer to determine the product price. Furthermore, the pricing system 100 reduces the workload imposed on the facility management company in determining the product price.

[0032] According to the price determination system 100, the selling price and stock rate for the desired delivery date are output to the facilities management company, so that the reason for the determined price can be notified.

[0033] (Second embodiment) The price determination system, price determination method, and program according to the second embodiment will be described below. In the second embodiment, the same components as those in the first embodiment are designated by the same reference numerals, and their description will be omitted.

[0034] FIG. 3 is a diagram illustrating an example of a change in stock rate over time in the second embodiment. The inventory rate of a product changes over time. The trend of the inventory rate fluctuation in Figure 3 is upward, indicating that the inventory rate will continue to increase even after the desired delivery date T1. Because the inventory rate fluctuation trend is upward, the pricing system 100 proposes to lower the product price by shifting the proposed delivery date T2 to a date later than the desired delivery date T1.

[0035] The coefficient determination unit 106 in this price determination system 100 determines a first coefficient for a different proposed delivery date T2 that has a higher inventory rate than the inventory rate of the desired delivery date T1 based on the trend of inventory rate fluctuations. The coefficient determination unit 106 also determines a second coefficient for an inventory rate that is higher than the inventory rate of the product calculated by the inventory management unit 104.

[0036] The price determination unit 108 determines an estimated price, which is a price of the product different from the selling price, based on the desired quantity, the base price, the first coefficient, and the second coefficient. The output unit 110 outputs the sales price for the desired delivery date and the estimated price for a delivery date different from the desired delivery date to the terminal device 310 of the equipment management company.

[0037] FIG. 4 is a flowchart showing an example of a processing procedure of the price determination system 100 according to the second embodiment. First, the acquiring unit 102 acquires product information, desired delivery date information, and desired quantity information (step S100), and also acquires inventory quantity information (step S102).

[0038] Next, the inventory management unit 104 calculates the fluctuation trend of the inventory rate (step S104).

[0039] Next, the price determination system 100 determines whether to propose a delivery date with a higher inventory rate than the inventory rate of the desired delivery date (step S106). The price determination system 100 determines whether a delivery date different from the desired delivery date will have a higher inventory rate than the inventory rate of the desired delivery date, and if the inventory rate is higher than the inventory rate of the desired delivery date, determines to propose a delivery date with a higher inventory rate than the inventory rate of the desired delivery date.

[0040] A delivery date different from the desired delivery date is, for example, a delivery date that falls within a range that the facilities management company can accept with respect to the desired delivery date. A delivery date different from the desired delivery date may be a delivery date later than the desired delivery date, or a delivery date earlier than the desired delivery date. When proposing a delivery date earlier than the desired delivery date as a delivery date different from the desired delivery date, pricing system 100 may propose a delivery date earlier than the desired delivery date if the price decrease caused by the inventory rate of the proposed delivery date being higher than the inventory rate of the desired delivery date exceeds the price increase caused by bringing the delivery date forward.

[0041] If a delivery date with a higher inventory rate than the inventory rate for the desired delivery date is not proposed (step S106: NO), the coefficient determination unit 106 calculates the first coefficient and second coefficient for the desired delivery date (step S108), the price determination unit 108 determines the sales price for the desired delivery date (step S110), and the output unit 110 outputs information including the desired delivery date, inventory rate, and sales price (step S116).

[0042] When proposing a delivery date with a higher inventory rate than the inventory rate for the desired delivery date (step S106: YES), the coefficient determination unit 106 calculates the first coefficient and the second coefficient for the proposed delivery date (step S112), the price determination unit 108 determines the estimated price for the proposed delivery date (step S114), and the process proceeds to step S108. The coefficient determination unit 106 calculates the first coefficient and the second coefficient for the desired delivery date (step S108), and the price determination unit 108 determines the sales price for the desired delivery date (step S110). Then, the output unit 110 outputs information including the desired delivery date, inventory rate, and sales price, and information including the proposed delivery date, inventory rate, and estimated price (step S116).

[0043] As described above, the pricing system 100 of the second embodiment determines a first coefficient for a different delivery date with a higher inventory rate than the desired delivery date based on the trend of inventory rate fluctuations, determines a second coefficient for a higher inventory rate than the product's inventory rate, and determines an estimated price, which is a product price different from the sales price, based on the desired quantity, base price, first coefficient, and second coefficient. The pricing system 100 can then notify the facility management company that the price can be reduced by shifting the desired delivery date. Furthermore, the pricing system 100 can sell a product with a delivery date later than the desired price if the delivery date corresponding to the estimated price is accepted.

[0044] Furthermore, if the inventory rate decreases after the desired delivery date, the pricing system 100 may notify the facility management company of the estimated price that the second coefficient will increase and the price will rise after the desired delivery date. This allows the pricing system 100 to increase the willingness to purchase the product by the desired delivery date.

[0045] (Third embodiment) The following describes a price determination system, a price determination method, and a program according to the third embodiment. In the third embodiment, the same components as those in the above-described embodiments are designated by the same reference numerals, and their description will be omitted.

[0046] FIG. 5 is a block diagram showing an example of the configuration of a price determination system 100A according to the third embodiment. The price determination system 100A includes a contract management unit 120. The contract management unit 120 acquires contract information indicating whether or not the facility management company has concluded a contract regarding shortening the delivery time of the product, and stores the acquired contract information in the storage unit 112. The contract is, for example, a contract under which the facility management company can shorten the delivery time of the product by periodically charging the facility manufacturer. When a contract has been concluded with the facilities management company, the coefficient determination unit 106 determines the first coefficient to be a smaller value than when no contract has been concluded.

[0047] FIG. 6 is a flowchart showing an example of a processing procedure of the price determination system 100A according to the third embodiment. First, the acquisition unit 102 acquires product information, desired delivery date information, and desired quantity information (step S200). The acquisition unit 102 also acquires inventory quantity information (step S202). Next, the inventory management unit 104 calculates the fluctuation trend of the inventory rate (step S204). Next, the coefficient determination unit 106 determines a first coefficient based on the desired delivery date and determines a second coefficient based on the fluctuation trend of the product inventory rate (step S206).

[0048] Next, the coefficient determination unit 106 determines whether or not there is a contract for shortened delivery time with the facility management company (step S208). If the facility management company has a contract for shortened delivery time, the coefficient determination unit 106 changes the first coefficient to a smaller value than when there is no contract (step S210). Next, the price determination unit 108 determines the sales price for the desired delivery time (step S212), and the output unit 110 outputs information including the desired delivery time, inventory rate, and sales price (step S214).

[0049] According to the third embodiment of the pricing system 100A, if the facility management company has signed a contract for shortening the delivery time of the product, the first coefficient is set to a small value, thereby suppressing the increase in price relative to the delivery time. This allows the pricing system 100A to encourage the facility management company to sign the contract.

[0050] A program for realizing some or all of the functions of the pricing system 100, 100A may be recorded on a computer-readable recording medium, and the program recorded on the recording medium may be read into a computer system and executed to perform construction management. Note that the term "computer system" here includes hardware such as the OS and peripheral devices.

[0051] Furthermore, if a WWW system is used, the "computer system" also includes the homepage provision environment (or display environment). Furthermore, "computer-readable recording media" refers to portable media such as flexible disks, optical magnetic disks, ROMs, and CD-ROMs, as well as storage devices such as hard disks built into computer systems. Furthermore, "computer-readable recording media" also includes devices that retain programs for a certain period of time, such as volatile memory within a computer system that serves as a server or client. The program may be a program that realizes part of the aforementioned functions, or may be a program that can realize the aforementioned functions in combination with a program already stored in the computer system. The program may also be stored on a designated server, and distributed (e.g., downloaded) via a communication line in response to a request from another device.
