It is not always essential to the solution of the invention.
[0016]
FIG. 1 shows a schematic configuration of an order management system 1 according to an embodiment of the present invention. The order management system 1 includes a plurality of order management devices 20a, 20b, 20c, and 20d (hereinafter, collectively referred to as an "order management device 20"), a plurality of order management devices 30a, 30b, 30c, and 30d ( Hereinafter, when collectively referred to as “order management device 30”), and transaction management device 10. The order management device 20 and the order management device 30 are respectively controlled by buyers and suppliers participating in the order management system 1. In principle, one buyer has control over one order management device 20, and similarly one supplier has control over one order management device 30. The transaction management device 10 is operated by the administrator of the order management system 1 and has a function of mediating transactions between buyers and suppliers.
[0017]
The transaction management device 10 and the order management device 20 are connected by a network such as the Internet. Similarly, the transaction management device 10 and the order management device 30 are also connected by a network. Buyers and suppliers are typically businesses, but are not so limited and may be individuals. The trading entity that participates in the order management system 1 can participate as a buyer or a supplier, but can also participate as both a buyer and a supplier.
[0018]
The outline of the behavior of each entity in the order management system 1 will be described. First, the order management device 20 transmits a quote request for a product or service to the order management device 30 via the transaction management device 10. The order management device 30 reads out relevant data from its own database, generates an estimation result, and transmits it to the order management device 20. The order management device 20 receives the estimation results presented from the plurality of order management devices 30, and selects one that meets the conditions. The order management device 20 generates order data and transmits it to the order management device 30. The order management device 20 accumulates the estimation result and the purchase results corresponding to the determined order contents, and uses the accumulated result for estimating the purchase amount or evaluating the estimated amount for the next and subsequent times. The above is the basic behavior of each subject in the order management system 1.
[0019]
FIG. 2 shows an example of an overview of a data model used in the order management system 1. Information on orders is categorized into six subject areas: “supplier”, “product / service”, “buyer”, “administrative cost item”, “reference price”, and “purchase result”. In the “supplier”, entities for specifying the purchaser / negotiator of the product or service are arranged. In the “goods / services”, entities for specifying goods / services purchased by buyers are arranged. In the "buyer", entities for specifying a payer, a negotiator, and the like are arranged. In the “management cost item”, entities related to the aggregation type of the buyer's payment cost are arranged. In the "reference price", the entities related to the market price of goods and services are arranged. In the “purchase record”, entities related to purchase of goods and services by buyers are arranged. In this example, “Reference Price” is created based on the “Supplier” and “Goods / Service” entities, and “Purchase Record” is “Supplier”, “Goods / Service”, “Buyer”, and “Administrative Cost Item”. Created based on the entity
[0020]
These subject areas are managed by at least one of the transaction management device 10, the order management device 20, and the order management device 30. For example, even if the order management device 20 manages “buyers”, “management costs”, “reference prices” and “purchase results”, and the order management device 30 manages “suppliers” and “goods / services”. Good. The transaction management device 10 manages a part or all of the subject area. It is easily understood by those skilled in the art that the classification of the subject area is not limited to the example of FIG.
[0021]
In the present embodiment, the information to be handled is divided into very fine data without being bound by the common sense of the conventional business customs. By segmenting the data, both buyers and suppliers can closely analyze the prices of goods or services. Specifically, the buyer can judge whether there is a possibility of a price reduction negotiation based on the segmented estimate, and the supplier can appropriately review the offer price of the product or service according to the trends of other companies.
[0022]
FIG. 3 shows an example of an entity belonging to the subject area “reference price”. The “reference price” is related to the entities “market price”, “competitor performance”, “publicly available materials” and “estimated results”. The data items of these entities are used in the order management device 20 as data elements for estimating the purchase price. By classifying the data relating to the reference price into a plurality of entities and further subdividing the data items, it is possible to appropriately execute the estimation of the purchase price and the evaluation of the estimated price.
[0023]
The “market price” describes the market price of a product or service. The “competitor record” describes the purchase price of another buyer. This data may be supplied from the transaction management device 10 with the approval of another buyer, or may be supplied directly from another buyer. In the “public information”, a price that is publicly disclosed is described. The “estimated result” describes the estimated amount of money by a plurality of suppliers. The buyer can use this information to get a rough idea of the price of the goods or services to be purchased and to evaluate the validity of the quotes sent by the supplier. Although FIG. 3 shows entities belonging to the subject area “reference price”, in the data model according to the present embodiment, similarly subdivided entities are set for other subject areas shown in FIG.
[0024]
FIG. 4 shows a detailed flow of the order processing in the order management system 1 according to the embodiment. The order management device 20 transmits a quote request to the transaction management device 10 (S10). The transaction management apparatus 10 searches its own database for suppliers dealing with goods or services to be dealt with (hereinafter referred to as “transaction object”) by a quote request, and transfers the quote request to the corresponding supplier. (S12). In this example, two suppliers correspond, and transfer the quote request to the respective order management devices 30a and 30b. The order management devices 30a and 30b respectively create estimates (S14, S16), and transmit the estimation results to the transaction management device 10 (S18, S22). The transaction management device 10 transfers the estimation result to the order management device 20 (S20, S24).
[0025]
The order management device 20 stores the estimation result as a reference price (S26). The buyer can estimate the purchase price based on the reference price when purchasing the transaction object next time. The buyer evaluates a plurality of estimation results and determines a supplier (S28). At this time, the buyer may negotiate a price with the supplier via the transaction management device 10. In this example, a supplier that has jurisdiction over the order management device 30a is determined as a purchaser.
[0026]
The order management device 20 generates order data specifying the supplier to be purchased, and transmits the generated order data to the transaction management device 10 (S30). The transaction management device 10 transfers the order data to the order management device 30a (S32). Upon receiving the order data, the order management device 30a confirms the content and transmits an order confirmation notification to the transaction management device 10 (S34). The transaction management device 10 transfers the order confirmation notification to the order management device 20 (S36). The order management device 20 recognizes that the order has been completed, and records the order details as purchase results (S38). As a result, the order management device 20 accumulates the estimation results from each supplier and the final order contents. Subsequently, the order management device 20 transmits the estimation result and the purchase result to the transaction management device 10 (S40), and the transaction management device 10 records them (S42). The estimation result and the purchase result recorded in the transaction management device 10 may be made open to other buyers, and at this time, the other buyers treat these data as reference prices.
[0027]
FIG. 5 shows a schematic configuration of the order management device 20. The order management device 20 includes a quotation request receiving unit 40, an ordering unit 42, a purchase amount estimating unit 44, a quotation receiving unit 46, a price receiving unit 48, an order confirmation unit 50, a transmission / reception unit 52, a reference price storage unit 54, and a purchase result storage. And a price information providing unit 58. The transmission / reception unit 52 has a function of transmitting and receiving data. The order management device 20 is realized by a CPU, a memory, a program loaded in a memory, and the like of an arbitrary computer in terms of hardware components. Here, functional blocks realized by their cooperation are illustrated. Therefore, it is understood by those skilled in the art that these functional blocks can be realized in various forms by hardware only, software only, or a combination thereof. The same applies to the order management device 30 and the transaction management device 10 to be described later. In the following, as an example of a transaction object, the provision of a “moving” service of an employee of a buyer company is taken as an example. Note that the management cost item at this time is “transfer travel cost” and is recorded after the order is placed.
[0028]
The quote request receiving unit 40 receives a quote request from a person in charge of the buyer. The request for quotation may be a request for a general or specific quotation for the intended traded object. A general estimate is a price list showing the relationship between the moving distance and the required number of personnel, and the specific estimate is an estimate created in accordance with conditions such as the actual travel distance and the amount of luggage. This quote request is transmitted from the transmission / reception unit 52 to the transaction management device 10. The transaction management device 10 transmits the quote request to the order management device 30, and transfers the estimation result created by the order management device 30 to the transmission / reception unit 52.
[0029]
The quotation receiving unit 46 receives quotation results presented from a plurality of suppliers via the transaction management device 10. The reference price storage unit 54 stores the estimation result as a reference price in association with the supplier. The estimation result is displayed on a display device (not shown) and confirmed by a person in charge.
[0030]
FIG. 6 is a comparison diagram for explaining the difference between the estimation in the present embodiment and the conventional estimation. In the figure, the left column shows an example of estimation in the present embodiment, and the right column shows an example of a conventional estimation. In the conventional example, the estimation table is created as a table of the distance division and the number of rooms, whereas in the example of the present embodiment, the estimation table is composed of the table of the distance division and the vehicle cost, the distance division and the work It is created as a table of unit cost. Since the order management device 30 classifies the information on the transaction object (moving) into very fine data, it is possible to create a subdivided estimate as shown in the figure. Therefore, the person in charge of the buyer can compare the estimation results from a plurality of suppliers, recognize the advantages and disadvantages of each supplier, and realize an appropriate ordering action.
[0031]
Returning to FIG. 5, the person in charge checks a plurality of estimation results and determines a supplier. When receiving the ordering instruction from the person in charge, the ordering unit 42 generates ordering data for specifying the supplier who has presented the estimation result. The supplier code included in the estimation result is inserted into the order data. The transmitting / receiving unit 52 transmits the generated order data to the transaction management device 10. Upon receiving the order data, the order management device 30 that is the ordering party issues an order confirmation notification, and the order confirmation unit 50 of the order management device 20 receives the order confirmation notification via the transmission / reception unit 52. When recognizing that the order processing in the order management device 30 has been completed, the order confirmation unit 50 stores the finally determined order details in the purchase result storage unit 56 as purchase results.
[0032]
The price receiving unit 48 receives a market price, a published price by a supplier, and a reference price acquired by another buyer, and accumulates it in the reference price storage unit 54 as its own reference price. The reference prices of the other buyers are recorded in the transaction management device 10. As a result, the reference price storage unit 54 stores, as the reference price, the estimation result obtained by itself, the market price, the open price by the supplier, and the reference price obtained by another buyer. The price information providing unit 58 transmits the reference price and the purchase result to the transaction management device 10.
[0033]
The purchase price estimation unit 44 estimates the purchase price based on the reference price stored in the reference price storage unit 54 in accordance with the purchase price estimation instruction from the person in charge. The purchase price estimation unit 44 may estimate the purchase price based on the purchase performance stored in the purchase performance storage unit 56, or may estimate the purchase price based on the reference price and the purchase performance. For example, the estimation of the purchase price is effective when it is desired to grasp in advance the cost of purchasing the product or service in the budget management business or to evaluate whether the obtained estimation result is appropriate. When estimating the purchase price using the purchase results, it is possible to perform highly accurate estimation because the actual transactions in the past are referred to.
[0034]
When estimating a specific purchase price, the data item relating to the transaction price included in the reference price or the purchase result is referred to. For example, when centralized purchasing is performed, the unit price is usually lower, so that it may be possible to estimate the purchase price by determining whether or not the current order quantity is certified as centralized purchasing for each supplier.
