It should be noted that the component learning model storage unit 32 will be described assuming that the data of the component learning model that has already been learned for a large number of components used in the product is already stored.

(1) Initial registration of ordered information In order for a processor to use the order support service provided by the server device SV, it is necessary to register the past order information stored by the processor in the server device SV. Therefore, the person in charge of receiving an order from the processor uses, for example, the terminal device MA1 used by himself / herself to transmit the plurality of stored ordered information to the server device SV together with the registration request.

As shown in FIG. 5, for example, each ordered information includes 3D CAD data which is design drawing information of a part, specification / supplementary information, and information representing an order history. Of these, the specifications and supplementary information include, for example, the material and hardness of parts, manufacturing instruction comments (points to note), and geometrical tolerances. In addition, the information representing the order history includes, for example, information indicating the name of the product manufacturer from which the parts are ordered, the date and time of the order, the quantity, the unit price, the delivery date, and the processing process. Of the information representing the order history, only the information representing the processing process is created by the processor, and the other information is the information instructed by the product manufacturer as ordering information.

The control unit 1 of the server device SV monitors the reception of the registration request for the ordered information in step S10 under the control of the ordered information acquisition unit 11. In this state, for example, when the registration request is received from the terminal device MA1, the ordered information acquisition unit 11 communicates a plurality of past ordered information transmitted from the terminal device MA1 together with the registration request in step S11 in the communication I / F4. The above-mentioned plurality of past ordered information received via the above is associated with the processor ID of the transmission source and stored in the ordered information storage unit 31.

It should be noted that a plurality of ordered information may be registered collectively or may be registered separately. Further, the compression coding method and the multiplexing method of the order information at the time of transmission can be arbitrarily selected.

(2) Search of order history (2-1) When a quotation request is received When a new quotation request is received from the product manufacturer, the person in charge of ordering the processor receives the 3D CAD data of the parts included in the above quotation request. Is transmitted from its own terminal device MA1 to the server device SV.

On the other hand, the control unit 1 of the server device SV monitors the search request related to the quotation request in step S12. When the search request is received in this state, the control unit 1 of the server device SV receives the 3D CAD data of the parts related to the quotation request received together with the search request under the control of the quotation / order reference information search processing unit 13. It is given to the component shape recognition processing unit 12. Then, the component shape recognition processing unit 12 is instructed to perform the component shape recognition process.

Upon receiving the instruction of the recognition process, the component shape recognition processing unit 12 first performs a process of recognizing the shape of the component from the 3D CAD data of the component related to the request for quotation. Next, a process of recognizing the shape of each of the parts from the 3D CAD data of the parts included in the past ordered information stored in the ordered information storage unit 31 is performed. These component recognition processes are performed, for example, as follows.

That is, the component shape recognition processing unit 12 first creates 2D image data from 20 vertices of the regular dodecahedron based on the 3D CAD data of the given component. Subsequently, a plurality of feature vectors are calculated from the created 2D image data, and the calculated plurality of feature vectors are given to the learning model stored in the component learning model storage unit 32 as explanatory variables. As a result, the recognition result of the component shape clustered according to the feature vector is output from the component learning model. Similarly, the component shape recognition processing unit 12 performs a process of recognizing the shape of a component by using the component learning model for each of a plurality of past ordered information stored in the ordered information storage unit 31.

When the part shape recognition process in the part shape recognition processing unit 12 is completed, the quotation / order reference information search processing unit 13 recognizes the shape of the part related to the quotation request recognized in step S13 in the past. Compare with the shapes of multiple ordered parts. Then, based on the comparison result, a similar part having a shape difference from the part related to the request for quotation within a preset range is searched from among the plurality of ordered parts in the past. As the shape comparison method, for example, a method of calculating the difference between the feature vectors calculated when recognizing the shape and a method of calculating the number of matching pixels between the images of the recognized parts are used. However, it is not limited to that.

Next, in step S14, the quotation / order reference information search processing unit 13 reads the past ordered information corresponding to the searched similar parts from the ordered information storage unit 31, and uses the ordered information as the quotation reference information. Is transmitted from the communication I / F4 to the terminal device MA1 of the search request source.

The processor refers to the content of the information indicating the order history included in the above-mentioned past ordered information sent from the server device SV, that is, the information indicating the quantity, unit price, delivery date and processing process, and responds to the request for quotation. To create. Then, the prepared reply to the quotation is returned from the terminal device MA1 to the requesting product manufacturer.

(2-2) When receiving an order request When an order request for new parts processing is received from the product manufacturer after answering the above quotation, the processor sends the 3D CAD data of the parts related to the order request from the terminal device MA1 to the server. Send to the device SV.

On the other hand, the control unit 1 of the server device SV monitors the search request corresponding to the new order request in step S15. When the search request is received in this state, the control unit 1 of the server device SV obtains the 3D CAD data of the order target part related to the order request in step S16 under the control of the quotation / order reference information search processing unit 13. It is given to the shape recognition processing unit 12. Then, the part shape recognition processing unit 12 is instructed to perform the shape recognition processing of the ordered parts and the past ordered parts.

When the part shape recognition processing unit 12 receives the instruction of the recognition processing, the part shape recognition processing unit 12 recognizes the shape of the part from the 3D CAD data of the order target part, and a plurality of past stored in the ordered information storage unit 31. The process of recognizing the shape of each part from the 3D CAD data of the ordered part related to the ordered information is performed by using the parts learning model. Since the recognition process of these parts is the same as that at the time of requesting the quotation described above, the description thereof will be omitted again.

When the part shape recognition process in the part shape recognition processing unit 12 is completed, the quotation / order reference information search processing unit 13 recognizes the recognized shapes of the parts to be ordered in the past in step S16. Compare with the shape of the ordered parts. Then, based on the comparison result, a similar part having a shape difference from the order target part within a preset range is searched from among the plurality of ordered parts in the past.

Next, in step S17, the quotation / order reference information search processing unit 13 reads the past ordered information corresponding to the searched similar parts from the ordered information storage unit 31, and reads the ordered information into the processing process and the like. Is transmitted from the communication I / F4 to the terminal device MA1 of the search request source as reference information when designing.

The processor designs the processing process and the like of the parts ordered this time with reference to the above-mentioned past ordered information sent from the server device SV. Then, new order information including information indicating the designed processing process is created as follows. That is, the new order information includes the 3D CAD data of the parts received from the product manufacturer together with the order request and the specifications / supplementary information as they are, and the product manufacturer name, order date / time, quantity, and unit price of the ordering source included in the order history. And add the information indicating the above processing process to the delivery date and include this as the order history.

(3) Additional registration of new order information The processor transmits the created new order information together with the registration request from the terminal device MA1 to the server device SV.

On the other hand, the control unit 1 of the server device SV monitors the registration request of the new order information in step S18. When the registration request is received in this state, the control unit 1 of the server device SV communicates the new order information transmitted from the terminal device MA1 in step S19 under the control of the new order information registration processing unit 14. Received via / F4, the received new order information is additionally stored in the ordered information storage unit 31 in association with the processor ID of the registration request source.

(Action / effect)
As described above, the server device SV according to the embodiment performs the following order support processing. That is, the server device SV acquires the past multiple ordered information stored by the processor from the terminal devices MA1 to MAn of the processor and stores it in the ordered information storage unit 31. In this state, when the processor receives a new quotation request or order request from the product maker and transmits the 3D CAD data of the order target part related to the quotation request or the order request, the 3D CAD data of the order target part is used to obtain the relevant part. In addition to recognizing the shape, the shape of the ordered part included in the past ordered information stored in the ordered information storage unit 31 is recognized. Then, by comparing the recognized shape of the ordered part with the shape of the plurality of ordered parts in the past, a part similar to the shape of the ordered part among the plurality of past ordered parts is obtained. To search for. Then, the past ordered information corresponding to the searched similar parts is transmitted to the terminal devices MA1 to MAn used by the processor of the search request source.
