[Technical field]

[0001] The present invention relates to an information processing device and an information processing method. [Background technology]

[0002] There are known techniques for assisting in estimating the expected costs when procuring new parts from a supplier. For example, Patent Document 1 discloses an invention that determines whether the estimated manufacturing costs of a machine part are within an expected range. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2020-021462 A Summary of the Invention [Problem to be solved by the invention]

[0004] By the way, a purchasing manager may acquire knowledge about effective purchasing conditions (e.g., items to be ordered, payment terms, delivery date, relationship with the supplier, etc.) for reducing costs through experience based on past purchasing records.

[0005] However, the technology disclosed in Patent Document 1 does not take past purchasing records into consideration, and therefore effective purchasing conditions based on past purchasing records are not reflected in the manufacturing cost estimate. Therefore, even if such a technology is used, there is a possibility that opportunities to reduce manufacturing costs will be missed.

[0006] An object of the present invention is to provide an information processing device that can reduce costs when purchasing products and the like. [Means for solving the problem]

[0008] According to this configuration, by using past purchase records of the order target, it is possible to reduce ordering costs.

[0009] Another aspect of the present invention is the above-mentioned information processing device, wherein the order data further includes fifth information indicating a method of payment when ordering the order object, and the model generation unit generates the learning model using the first to fifth information as independent variables.

[0010] In this configuration, the payment method used when placing an order for a past order is used, so that it is possible to reduce ordering costs more effectively.

[0011] Another aspect of the present invention is the above-mentioned information processing device, wherein the order data further includes sixth information indicating an estimated price of the order object, and the model generation unit generates the learning model using the first to sixth information as independent variables.

[0012] In this configuration, the estimated price at the time of purchasing the order target in the past is used, so that it is possible to reduce the order cost more effectively.

[0013] Another aspect of the present invention is the above-mentioned information processing device, wherein the order data further includes seventh information indicating the type of contract for the order target, and the model generation unit generates the learning model using the first to seventh information as independent variables.

[0014] In this configuration, the contract method of the past order target is used, so that it is possible to reduce the ordering cost more effectively.

[0015] Another aspect of the present invention is the above-mentioned information processing device, wherein the order data further includes eighth information indicating a bidding method for ordering the order target, and the model generation unit generates the learning model using the first to eighth information as independent variables.

[0016] In this configuration, the bidding method used when placing orders for past order items is used, so that it is possible to reduce ordering costs more effectively.

[0017] Another aspect of the present invention is the information processing device, wherein the order data further includes ninth information indicating a contracting party of the order target, and the model generation unit generates the learning model using the first to ninth information as independent variables.

[0018] In this configuration, since the contracting party to which the order is placed is used, it is possible to reduce the ordering cost more effectively.

[0019] Another aspect of the present invention is the above-mentioned information processing device, wherein the order data further includes tenth information indicating a trading period with the contracting party, and the model generation unit generates the learning model using the first to tenth information as independent variables.

[0020] In this configuration, since the transaction period with the contracting party is used, it is possible to reduce the ordering cost more effectively.

[0021] Another aspect of the present invention is the above-mentioned information processing device, wherein the order data further includes eleventh information regarding sales of the contracting party to an orderer of the order target, and the model generation unit generates the learning model using the first to eleventh information as independent variables.

[0022] In this configuration, since information on sales of the contracting party to the ordering party of the order target is used, it is possible to reduce ordering costs more effectively.

[0023] Another aspect of the present invention is an information processing device comprising: a memory unit that stores a tree-structured learning model generated for each of a plurality of order objects using a plurality of order data including, as independent variables, first information indicating the budget of an order object, second information indicating the actual cost of the order object, third information indicating the time when the order object was ordered, and fourth information indicating the delivery date of the order object, and including, as dependent variables, amount information indicating the relationship between the budget of the order object and the actual cost of the order object; and an output unit that outputs the analysis results of the learning model corresponding to the input order object from among the plurality of learning models.

[0063] In other words, A and B represent cases where the purchases were made at a higher cost than the budget, C represents cases where the purchases were made at a cost almost equal to the budget, and D and E represent cases where the purchases were made at a lower cost than the budget.

[0064] [Functional blocks of information processing equipment] 4 is a diagram showing functional blocks of the information processing device 2 of this embodiment. In the information processing device 2 of this embodiment, an acquisition unit 30, a model generation unit 31, a storage unit 32, an input reception unit 33, and an output unit 34 are realized by the processor 20 executing a predetermined program.

[0065] The acquiring unit 30 acquires a plurality of pieces of order data stored in advance in the auxiliary storage device 22 when the model generating unit 31 generates a learning model.

[0066] The model generation unit 31 generates a learning model based on a tree-structured learning model, using the information 50a to 50c, 51a to 51e, and 52a to 51c (first to eleventh pieces of information) in FIG. 3 as independent variables and the item 53 (discount) as a dependent variable. The "tree-structured learning model" is, for example, a decision tree or a random forest. The decision tree includes a classification tree and a regression tree. In this embodiment, an aspect using a classification tree will be described.

[0067] The storage unit 32 stores the decision tree generated using a plurality of pieces of order data for each of a plurality of order targets.

[0068] The input receiving unit 33 receives input from the outside via a user interface such as the output device 24 or an input screen displayed on the user terminal 4.

[0069] The output unit 34 outputs the analysis result of the learning model corresponding to the order target input by the user, out of the multiple learning models.

[0070] [Processing up to generating a learning model] 5 is a flowchart illustrating the flow of processing up to generation of a learning model by the information processing device 2. The processing up to generation of a learning model includes step S11 and step S12.

[0071] First, in step S11, the acquisition unit 30 of the information processing device 2 acquires a plurality of pieces of order data for a predetermined order target from among the plurality of pieces of order data stored in the auxiliary storage device 22. The plurality of pieces of order data shown in Fig. 3 are an example of the plurality of pieces of order data acquired by the acquisition unit 30 in step S11.

[0072] Next, in step S12, the model generation unit 31 of the information processing device 2 generates a learning model based on a decision tree using the multiple order data shown in Fig. 3. At this time, the learning model based on the decision tree is generated using the information 50a to 50c, 51a to 51e, and 52a to 51c in Fig. 3 as independent variables and the evaluation (information 53b), which is a discrete value, as a dependent variable.

[0073] Specifically, in this embodiment, since the dependent variable is the evaluation (information 53b) which is a discrete value, a learning model is generated using a classification tree. Note that the algorithm for generating a learning model using a decision tree is not particularly limited.

[0074] Fig. 6 is a diagram showing a decision tree 6a generated by the model generation unit 31 in step S12 using the multiple pieces of order data shown in Fig. 3. In this example, multiple pieces of order data are classified according to the order timing, the delivery method, and the delivery date.

[0075] In this example, the number of classifications and the depth of the tree are limited to avoid overfitting. Furthermore, in this example, a decision is made as to whether or not to further classify a node based on the evaluation function at the node and a predefined threshold.

[0076] The evaluation function for a node can be, for example, the product of the information gain at the node and the number of data at the node. The information gain at a node (parent node) is the difference between the impurity of the parent node and the impurity of multiple nodes (child nodes) after classifying the parent node. The impurity of multiple child nodes is the sum of the impurity of each of the multiple child nodes weighted by the number of data of the child node for that child node for all of the multiple child nodes. As the impurity, Gini impurity, entropy, etc. can be used.

[0077] In Figure 6, first, all of the multiple order data are classified by the time of order (node ​​n1). As a result, for order data with an order date in March, the evaluation function is smaller than a predetermined threshold, so division is terminated. Such conditions are then classified as evaluation E. Meanwhile, order data with an order date other than March is further classified.

[0078] Next, all order data that was placed in a month other than March is classified by payment method (node ​​n2). As a result, the order data that is paid in a lump sum and the order data that is paid in installments are further classified.

[0079] Next, all order data that was ordered in a month other than March and that was paid in one lump sum is classified by delivery date (node ​​n3). As a result, for order data with delivery dates of 10 months or more, the evaluation function is smaller than the specified threshold, so classification is terminated. Such conditions are then classified as evaluation E. On the other hand, order data with delivery dates of less than 10 months is further classified.

[0080] In FIG. 6, the dashed lines at the ends of the branches indicate that further classification conditions are not shown.

[0081] The above-described process completes the process for generating the learning model. Learning models for other order targets are generated by a similar process. The learning models based on the decision trees generated for each of the multiple order targets are linked to the product code and stored in the storage unit 32. FIG. 7 is a diagram showing the decision trees for each of the multiple order targets stored in the storage unit 32.

[0082] [Processing until analysis results are displayed] 8 is a flowchart explaining the flow of processing up to when the information processing system 1 displays the analysis results. The processing up to when the analysis results are displayed includes steps S21 to S26. In this example, a user operates the user terminal 4. The user does not necessarily have much experience in purchasing. It is also assumed that the user has taken on the role of purchasing a denitration device and is considering placing an order for the denitration device.

[0083] First, in step S21, the user inputs a product code that identifies a desired order target via the input screen 40 displayed on the user terminal 4. Fig. 9 is a diagram showing an example of the input screen 40 at this time.

[0084] An input screen 40 displays a product code input window 40a, a major category selection window 40b, a medium category selection window 40c, and a minor category selection window 40d. A user can input a product code that identifies the denitrification device that is the desired item to be ordered into the product code input window 40a.

[0085] In addition, the user can input a product code identifying the denitrification equipment by selecting an item corresponding to the desired order item from each of the major category selection window 40b, the medium category selection window 40c, and the minor category selection window 40c.

[0086] At this time, the user places the mouse cursor on the major category selection window 40b and clicks, whereupon a drop-down list is displayed from which the user can select the major category item (thermal power plant construction) to which the denitrification device belongs.

[0087] Similarly, the user selects the medium category (boiler-related) to which the denitration equipment belongs from the medium category selection window 40c. Next, similarly, the user selects the denitration equipment from the small category selection window 40d. Accordingly, the product code identifying the denitration equipment is automatically input into the product code input window 40a. After inputting the product code using one of the above procedures, the user clicks the OK button.

[0088] The input receiving unit 33 of the information processing device 2 receives the product code input to the user terminal 4 in step S22.

[0089] In step S23, the input receiving unit 33 identifies a decision tree for the received product code. Specifically, the input receiving unit 33 searches the storage unit 32 for the received product code, and identifies a decision tree associated with the searched product code.

[0090] In step S24, the acquiring unit 30 acquires a learning model based on the identified decision tree from the storage unit 32. That is, the acquiring unit 30 acquires the tree structure, the classification conditions at each node, the evaluation at each endpoint, and the like of the identified decision tree.

[0091] In step S25, the output unit 34 outputs to the user terminal 4 the analysis result based on the learning model acquired by the acquisition unit.

[0092] The "analysis result" is information based on each classification condition of the evaluation (information 53b) which is the dependent variable. The information based on each classification condition of the evaluation (information 53b) may be, for example, the classification condition or a comment based on the classification condition.

[0093] In step S26, the user terminal 4 displays the analysis result received from the information processing device 2 on the output screen 41. Fig. 10 is a diagram showing an example of the output screen 41 at this time.

[0094] A product code 41a entered by a user, a decision tree 6a for the product code, and an analysis result 41b based on the decision tree are displayed on the output screen 41. The decision tree displayed in FIG. 10 is the decision tree shown in FIG.

[0095] Also, in this example, a comment based on the classification condition of evaluation E is displayed as the analysis result 41b. The analysis result 41b displayed on the output screen 41 describes the classification corresponding to the end points t1 and t2 of the decision tree shown in FIG. 6. End point t1 is a classification in which the order target is placed in March. End point t2 is a classification in which the order target is placed in a month other than March, the payment method is a lump sum, and the delivery date is less than 10 months. End points t1 and t2 are classified as evaluation E on a five-point scale. A comment explaining this result is displayed in the analysis result 41b.

[0096] The user can further display the details of the classification of other endpoints by clicking "Next" shown in the analysis result 41b (not shown). The user can refer to such analysis results when ordering a denitration device.

[0097] The above-mentioned embodiment is for the purpose of facilitating understanding of the present invention, and is not intended to limit the present invention. Furthermore, the present invention can be modified or improved without departing from the spirit of the present invention, and it goes without saying that the present invention includes equivalents thereof.

[0098] For example, in the present embodiment, the product (denitrification device) is used, but the product may be a construction project, a thermal power plant project, a nuclear power plant project, etc. Even in such a case, the information processing device 2 can appropriately reduce the cost when purchasing the product, etc. [Explanation of symbols]
