[0012] Hereinafter, a transaction support system, transaction support method, and program to which the present invention is applied will be described with reference to the drawings. However, the scope of this disclosure is not limited to the embodiments described below and can be modified as appropriate within the scope of the technical idea of ​​this disclosure.

[0013] (First Embodiment) First, a transaction support system, transaction support method, and program according to the first embodiment will be described. Figure 1 is a block diagram showing an example of a configuration including the transaction support system 100 according to the first embodiment. The transaction support system 100 is connected to, for example, a first customer system 200A, a second customer system 200B, an equipment manufacturer system 300, and an inventory management system 400 via a communication network NW. The transaction support system 100, the first customer system 200A, the second customer system 200B, the equipment manufacturer system 300, and the inventory management system 400 have a communication interface (not shown), such as a NIC (Network Interface Card) 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 WiFi (registered trademark).

[0014] The transaction support system 100 performs processing for providing a platform for forming a community among customers having the same product or parts. The products or parts in the embodiment are, for example, devices included in equipment and parts of the devices. The equipment is, for example, power generation equipment, the device is a generator, and the parts are bearings and the like.

[0015] The first customer system 200A includes an information processing device managed by customer A who has purchased a product or parts. The second customer system 200B includes an information processing device managed by customer B who has purchased a product or parts. The first customer system 200A and the second customer system 200B may include an information processing device managed by an equipment management company that operates equipment including the product. The first customer system 200A and the second customer system 200B include, for example, equipment, a control device for the equipment, a database device for managing the operating state of the equipment, a terminal device operated by a customer, and a communication device for communicating via a communication network.

[0016] The equipment manufacturer system 300 includes an information processing device managed by an equipment manufacturer that manufactures products included in the equipment and parts of the products. The equipment manufacturer system 300 includes, for example, a manufacturing device for products and parts, a database device that manages device information and part information, a terminal device operated by the equipment manufacturer, and a communication device that communicates via a communication network.

[0017] The inventory management system 400 includes an information processing device that manages the inventory of products or parts manufactured by the equipment manufacturer system 300. The inventory management system 400 includes, for example, storage facilities for products and parts such as devices as inventory items, a database device that manages inventory item information, a terminal device operated by the inventory manager, and a communication device that communicates via a communication network.

[0018] In an embodiment, for example, the first customer system 200A and the equipment manufacturer system 300 conclude a product sales contract (step 1). The equipment manufacturer system 300 manufactures based on the product sales contract (step 2), and the manufactured products or parts are stored as inventory items (step 3). It is assumed that customer B of the second customer system 200B previously purchased the same products or parts as customer A of the first customer system 200A. The transaction support system 100 forms a group (community) to which customers A and B who purchased the same products or parts belong.

[0019] Thereafter, it is assumed that customer A (the first customer), who wishes to transfer a product or part, transmits information to the transaction support system 100 indicating that the product or part may be transferred (step 4). In response, the transaction support system 100 outputs information to customers A and B indicating that the product or part may be transferred. It is assumed that customer B, who wishes to purchase a product or part, transmits information to the transaction support system 100 indicating that they wish to purchase (step 4). In response, the transaction support system 100 outputs information to customers A and B indicating that the product or part may be purchased.

[0020] Subsequently, when the time comes for the product or component to be shipped, it is shipped to the customer who owns it at the required time (Step 5). If a transfer agreement for the product held by customer A has not been concluded, the product is shipped to customer A as shown in Figure 1. If a transfer agreement for the product has been concluded between customer A and customer B, the product is shipped to customer B (not shown). The functions of the transaction support system 100, which forms such groups and supports transactions, will be described below.

[0021] Figure 2 is a block diagram showing an example of the configuration of the transaction support system 100 in the first embodiment. The transaction support system 100 includes, for example, a sales information collection unit 102, a sales management unit 104, a group management unit 106, a storage unit 108, an acquisition unit 110, and an output unit 112. The sales information collection unit 102, the sales management unit 104, the group management unit 106, the acquisition unit 110, and the output unit 112 are functional units realized by a processor, such as a CPU (Central Processing Unit), executing a program stored in program memory. The storage unit 108 is a storage device such as memory. The storage unit 108 may also be an external storage device connected to the transaction support system 100, such as a database server.

[0022] The sales information collection unit 102 collects sales information, including product information, customer information, and sales volume information. For example, the sales information collection unit 102 collects product information, customer information, and sales volume information for each product sales contract from the equipment manufacturer system 300, the first customer system 200A, or the second customer system 200B. Product information is information that identifies a product or part, such as a product ID or part ID. Customer information is information that identifies customers, such as first customer and second customer. Sales volume information is information that shows the number of products or parts sold.

[0023] The sales management department 104 stores sales history information in the storage unit 108. The sales history information is information that associates a product or part with the customer who purchased the product or part. The sales management department 104 creates sales history information based on the information collected by the sales information collection department 102.

[0024] Based on the sales history information, the group management department 106 creates customer groups for each type of product purchased by the customers or for each type of part included in the product. The group management department 106 stores in the storage unit 108 group information indicating the groups and the customers included in the groups.

[0025] The acquisition unit 110 acquires transferable information indicating that transfer by a first customer who wishes to transfer a product or part may be allowed, or purchase wish information indicating that a second customer who wishes to purchase a product or part wishes to purchase. The transferable information includes product information such as a product ID, customer information, and quantity information. The purchase wish information includes product information such as a product ID, customer information, and quantity information.

[0026] The output unit 112 outputs the transferable information acquired by the acquisition unit 110 to the terminals of the customers belonging to the group for each product or part created by the group management department 106. For example, the output unit 112 recognizes the group based on the product information included in the transferable information and transmits the transferable information to the customers included in the recognized group.

[0027] The output unit 112 outputs the purchase wish information acquired by the acquisition unit 110 to the terminals of the customers belonging to the group for each product or part created by the group management department 106. For example, the output unit 112 recognizes the group based on the product information included in the purchase wish information and transmits the purchase wish information to the customers included in the recognized group.

[0028] FIG. 3 is a diagram showing an example of a group in the embodiment. For example, if product a and product b are being sold, the group management unit 106 forms a product a group that includes customers A and B included in the sales history information of product a, and a product b group that includes customers B, C, D, and E included in the sales history information of product b.

[0029] For example, if customer A's first customer system 200A outputs transferable information S1 for product a, the transaction support system 100 outputs the transferable information S1 to customer B's second customer system 200B, which belongs to product a group. Also, if customer B's second customer system 200B outputs transferable information for product a, the transaction support system 100 outputs the transferable information to customer A's first customer system 200A, which belongs to product a group.

[0030] For example, if customer B's second customer system 200B outputs transferable information S10 for product b, the transaction support system 100 outputs the transferable information S10 to the customer systems of customers C, D, and E, who belong to the product b group. If customer C's customer system outputs transferable information S12 for product b, the transaction support system 100 outputs the transferable information S12 to the customer systems of customers B, D, and E, who belong to the product b group. If customer B's second customer system 200B outputs purchase request information S20 for part b1 of product b, the transaction support system 100 outputs the purchase request information S20 to the customer systems of customers C, D, and E, who belong to the product b group.

[0031] Figure 4 is a sequence diagram showing an example of the processing of the transaction support system 100 in the embodiment. First, when customer A purchases a product, the equipment manufacturer system 300 transmits information S10, which includes product information, customer information, and sales volume information, to the transaction support system 100. The sales information collection unit 102 then retrieves the information S10, and the sales management unit 104 stores the sales history information in the storage unit 108.

[0032] The group management department 106 forms a group including customer A and customer B based on sales history information. Furthermore, the product purchased by customer A is managed as inventory by the inventory management system 400.

[0033] When customer A's first customer system 200A outputs transferable information S12 to the transaction support system 100, the output unit 112 transmits transferable information S14 to customer B's second customer system 200B. This allows customer B to consider purchasing products from customer A based on the transferable information S14. When the second customer system 200B outputs purchase request information S16 to the transaction support system 100, the output unit 112 transmits the purchase request information S16 to customer A's first customer system 200A. As a result, customer A can then contact customer B based on the purchase request information S16. Selling products to It can be considered that this should be done.

[0034] When a product transfer agreement is concluded between customer A and customer B, for example, the second customer system 200B outputs product quantity information S22 to the transaction support system 100, and the first customer system 200A outputs product quantity information S22 to the transaction support system 100. As a result, the sales management department 104 can update the sales history information because ownership of the product has been transferred from customer A to customer B.

[0035] The transaction support system 100 outputs information S24, which includes customer information and inventory information, to the equipment manufacturer system 300 in response to the update of sales history information. As a result, the equipment manufacturer system 300 can output shipping information S26 to the second customer system 200B, indicating that the product transferred from customer A to customer B will be shipped to customer B.

[0036] As described above, the transaction support system 100 of the first embodiment can form a group of products or parts including multiple customers and output transferable information or purchase request information to customers belonging to the group. This allows customers to consider purchasing the product or parts from other customers, or purchasing the product or parts from the equipment manufacturer system 300, taking into account the transferable information of other customers belonging to the group. In addition, customers can consider transferring the product or parts to other customers, taking into account the purchase request information of other customers belonging to the group. As a result, the transaction support system 100 can facilitate transactions of products or parts.

[0037] (Second Embodiment) Next, a transaction support system, transaction support method, and program according to the second embodiment will be described. Note that parts identical to those in the first embodiment will be denoted by the same reference numerals, and detailed explanations will be omitted.

[0038] Figure 5 is a block diagram showing an example of a transaction support system 100A according to the second embodiment. Transaction support system 100A differs from transaction support system 100 in that it includes a calculation unit 104a. The calculation unit 104a calculates the sales quantity of a product or part for each customer based on the sales history information stored in the sales management unit 104. The sales management unit 104 stores the sales quantity for each customer calculated by the calculation unit 104a in the storage unit 108. The output unit 112 outputs sales quantity information, which shows the sales quantity of a product or part for each customer, to the customer system belonging to the group for each product or part.

[0039] According to the transaction support system 100A of the second embodiment, the transaction support system 100A outputs the sales quantity for each customer to the customer system belonging to the group for each product or part, so that the number of products purchased by other customers belonging to the group can be displayed. This allows customers to consider purchasing products or parts from other customers, transferring products or parts to other customers, and purchasing products or parts from the equipment manufacturer system 300, taking into account the number of products purchased by other customers belonging to the group. Furthermore, according to the transaction support system 100A, by checking the number of products purchased by other customers, it becomes easier to approach other customers, and transactions of products or parts can be further promoted.

[0040] (Third embodiment) Next, a transaction support system, transaction support method, and program according to the third embodiment will be described. Note that parts identical to those in the first embodiment will be denoted by the same reference numerals, and detailed explanations will be omitted.

[0041] Figure 6 is a block diagram showing an example of the transaction support system 100B according to the third embodiment. Transaction support system 100B differs from transaction support system 100 in that its acquisition unit 110 acquires customer holding quantity information. Customer holding quantity information is information indicating the quantity of transferable products or parts held by the customer. Transferable products or parts are, for example, products or parts that are managed as inventory by the inventory management system 400 and have not been shipped. Transferable products or parts may also be products or parts that have been shipped to the customer but are being stored by the customer without being used.

[0042] The output unit 112 outputs customer ownership information to customers belonging to groups for each product or part corresponding to the customer ownership quantity. Customer ownership information is information indicating the quantity of each product or part owned by each customer. Customer ownership information includes, for example, customer information, product information, and ownership quantity information.

[0043] According to the third embodiment of the transaction support system 100B, customer ownership information is output from the transaction support system 100B to the customer systems belonging to each group of products or parts, so that other customers belonging to the group can see the ownership numbers. This allows customers to consider purchasing products or parts from other customers, transferring products or parts to other customers, and purchasing products or parts from the equipment manufacturer system 300, taking into account the ownership numbers of other customers belonging to the group. Furthermore, according to the transaction support system 100B, by checking the ownership numbers of other customers, it becomes easier to approach other customers, and transactions of products or parts can be further promoted.

[0044] (Fourth embodiment) Next, a transaction support system, transaction support method, and program according to the fourth embodiment will be described. Note that parts identical to those in the above embodiments will be denoted by the same reference numerals, and detailed explanations will be omitted.

[0045] Figure 7 is a block diagram showing an example of the transaction support system 100C according to the fourth embodiment. The acquisition unit 110 acquires customer reliability information based on the customer's (first customer's) sales history information. The reliability information may be the reliability of the customer that outputs transferable information, or it may be the reliability of the customer that outputs purchase request information. The reliability information is information that indicates the reliability of the customer calculated based on the sales history information. For example, the more times a customer has purchased from the equipment manufacturer system 300, the higher their reliability will be calculated. Also, the more times a customer has transferred to other customers, the higher their reliability will be calculated, and the more times a customer has purchased from other customers, the higher their reliability will be calculated.

[0046] The output unit 112 outputs customer reliability information to customers belonging to groups for each product or part. For example, when the output unit 112 receives transferable information or purchase request information from a customer, it outputs the reliability information of that customer.

[0047] According to the transaction support system 100C of the fourth embodiment, customer reliability information is output based on the customer's sales history information, allowing the reliability of customers who have output transferable information or purchase request information to be confirmed. This makes it easier to approach customers by confirming their reliability, and further promotes transactions of products or parts.

[0048] (Fifth embodiment) Next, a transaction support system, transaction support method, and program according to the fifth embodiment will be described. Note that parts identical to those in the above embodiments will be denoted by the same reference numerals, and detailed explanations will be omitted.

[0049] Figure 8 is a block diagram showing an example of the transaction support system 100D according to the fifth embodiment. The acquisition unit 110 acquires quality inspection information for products or parts transferred from the first customer. The quality inspection information is information indicating the results of an inspection of the products or parts transferred from the first customer by a third-party organization. The third-party organization may be, for example, the administrator of the transaction support system 100D, an equipment manufacturer, or an inventory manager. The inspection costs may be borne by the transferring customer or the transferring customer, and the administrator of the transaction support system 100D may charge the transferring customer or the transferring customer a fee when the transfer agreement is concluded.

[0050] The output unit 112 outputs to customers belonging to the product or part group created by the group management unit 106, the product ID indicating the product or part for which the transferable information is available, and the quality inspection information for that product ID.

[0051] According to the fifth embodiment of the transaction support system 100D, quality inspection information of products or parts to be transferred by the customer is output, so that the transferable information allows the customer to confirm the quality inspection information of the products or parts to be transferred. As a result, by confirming the quality inspection information, it becomes easier to approach the customer and further promote the transaction of products or parts.

[0052] (Sixth Embodiment) Next, a transaction support system, transaction support method, and program according to the sixth embodiment will be described. Note that parts identical to those in the embodiments described above will be denoted by the same reference numerals, and detailed explanations will be omitted.

[0053] Figure 9 is a block diagram showing an example of a transaction support system 100E according to the sixth embodiment. The acquisition unit 110 acquires transferable information and storage status information of the product or part corresponding to the transferable information. The storage status information is information indicating the storage status of the product or part at the first customer. Storage status includes, for example, storage location, storage period, temperature, and other environmental factors. If the product or part is in stock, the acquisition unit 110 acquires storage status information including information identifying the inventory management system 400, the location of the inventory management system 400, and the storage period. If the product or part is stored by the customer, the acquisition unit 110 acquires storage status information from the customer.

[0054] The output unit 112 outputs a product ID indicating the product or part for which transferable information is available, and storage status information, to customers belonging to the product or part group created by the group management unit 106.

[0055] According to the transaction support system 100E of the sixth embodiment, information on the storage status of products or parts to be transferred from the customer is output, allowing the storage status of the products or parts to be transferred to be confirmed by the transferable information. This makes it easier for customers to approach the company by checking the storage status, and further promotes the transaction of products.

[0056] Construction management may be performed by recording a program to implement some or all of the functions of the transaction support systems 100, 100A, 100B, 100C, 100D, and 100E on a computer-readable recording medium, and then loading and executing the program recorded on this recording medium into a computer system. The term "computer system" here includes hardware such as the operating system and peripheral devices.
