[0046] Figure 3 It is a schematic physical structure diagram of an electronic device provided by the present invention. Detailed implementation manners

[0047] To make the objectives, technical solutions, and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions in the present invention in conjunction with the drawings in the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0048] The following will, in conjunction with the drawings, through specific embodiments and their application scenarios, provide a detailed description of the product process subcontracting management method provided by the embodiments of the present application.

[0049] Figure 1 It is a schematic flow chart of a product process subcontracting management method provided by the present invention. As Figure 1 shown, a product process subcontracting management method provided by the present invention is used for the subcontracting production of parts of rail vehicles. The method may include the following steps.

[0050] S100. Obtain production orders for several rail vehicles.

[0051] Optionally, obtaining production orders for several rail vehicles includes:

[0052] Converting in-line parts into the first sub-production order according to the column quantity;

[0053] Converting blanking parts into the second sub-production order according to the batch summary planned order;

[0054] Based on the first sub-production order and the second sub-production order, converting the planned orders generated by the material requirements planning of several rail vehicles into production orders.

[0055] Preferably, convert the planned orders generated by running the Materiel Requirements Planning (MRP) according to the production plan into production orders. When the process route operations change, automatically update the operations in the production order and record the change notice number for subsequent traceability.

[0056] S200. Query the process based on the production order to obtain subcontracting data.

[0057] Optionally, the subcontracting data includes:

[0058] Process-specified subcontracting data and / or temporary subcontracting data.

[0059] Optionally,

[0060] when the subcontracting data includes temporary subcontracting data;

[0061] Correspondingly, based on the subcontracting data, obtain all operation numbers, including:

[0062] Based on the temporary subcontracting data, obtain all operation numbers that have passed the temporary approval through temporary approval.

[0063] Preferably, the temporary subcontracting data is data related to a temporary subcontracting task initiated when the own production capacity is insufficient.

[0064] S300. Based on the subcontracting data, obtain all operation numbers. Among them, different operation numbers are used for any one of the operation description, operation content, and processing part that are different for the operations. Generate a unique number for each operation. Although the operation description is the same, if the operation content or processing part is different, multiple operation numbers are generated.

[0065] Optionally, based on the subcontracting data, obtain all operation numbers, including:

[0066] Based on the subcontracting data, obtain all operation numbers and the material codes required for the operations. Based on the material codes and operation numbers, overall consider the personalized production of in-line parts and the batch production of blanking parts.

[0067] Optionally, based on the subcontracting data, obtain all operation numbers, including:

[0068] In the process of in-line parts, the quantity of virtual self-made parts produced in the intermediate process is used as the number of operations in the intermediate process;

[0069] In the process of blanking parts, the quantity of materials produced is used as the number of operations in the process of blanking parts.

[0070] Design different business processing modes according to personalized production of pipeline parts and batch production of blanking parts. The personalized production of pipeline parts is the main production process. The materials produced in the intermediate process are not regarded as the materials produced by the work order, but are treated as virtual self-made parts. The number of processes in this part is calculated by taking the number of virtual self-made parts input into the next process as the number of processes. The processes of blanking parts are simple, and the number of materials produced by the work order is used as the number of processes. For pipeline part work orders, one work order produces one pipeline part. For blanking part work orders, one work order may produce multiple blanking part materials, and the same material code is used.

[0071] It should be noted that for temporary outsourcing data, the bill of materials and process route are automatically calculated through the background, and the virtual self-made parts of pipeline parts and the processes of blanking parts are sorted into the format of material + process, and then selected for approval to ensure the uniqueness of the source data of outsourcing. When facing the problem that the production order has not been issued during the approval of temporary outsourcing, by querying a certain column of the process route, filling in the start and end columns, after the approval is completed, arrange a background job to automatically query the issuance status of the production order and trigger the generation of an outsourcing purchase application. To solve the problem of uncertain outsourcing working hours, in the same approval process, the outsourcing quantity can be approved first, and after the quantity approval is completed, the business personnel are allowed to modify the working hours and continue to initiate the process approval.

[0072] S400. Calculate the standard outsourcing price for each process based on the process classification and process parameters corresponding to all process numbers.

[0073] Preferably, to calculate the standard outsourcing price of the process, the outsourcing processes are classified according to business types, including blanking, processing, pressing, welding, heat treatment, flaw detection, pipeline cleaning, etc. Different calculation parameters are set according to different types to achieve accurate calculation of the standard outsourcing price. For example, blanking is related to the blanking method, plate thickness, material, and equipment, then these parameters are set as process parameters, and the standard outsourcing price is automatically generated according to the process parameters. The standard outsourcing price is used to limit the bidding price to ensure the controllability of the company's outsourcing costs.

[0074] S500. Form the total outsourcing price based on the standard outsourcing prices of all processes.

[0075] Preferably, through querying the specified outsourcing data and / or temporary outsourcing data of the process, conduct bidding, and sign a contract with the supplier when the bidding price does not exceed the price limit.

[0076] In this embodiment, by numbering the outsourcing processes in the process, all processes used in outsourcing manufacturing in the process can be quickly predicted. Combining the process classification and process parameters, the total price of the outsourcing processes can be further quickly determined, thus providing a reference for the bidding work and reducing the outsourcing manufacturing cost.

[0077] Furthermore, the purchase application generated according to the production order is matched with the purchase contract to transfer to the purchase order, and the purchase quantity of the purchase order is restricted not to exceed the quantity of the purchase contract.

[0078] Optionally, the method further includes:

[0079] Obtain the layout drawing of the cut parts of the rail vehicle;

[0080] Generate the raw material quota of the rail vehicle based on the layout drawing;

[0081] Code the suppliers and obtain raw materials through the suppliers;

[0082] When the production order is completed, determine the raw material loss of the supplier based on the raw material quota, raw material code, supplier code, and work breakdown structure of the rail vehicle.

[0083] Optionally, when the production order is completed, determining the raw material loss of the supplier based on the raw material quota, raw material code, supplier code, and work breakdown structure of the rail vehicle includes:

[0084] When the production order is completed, determine the raw material loss of the supplier based on the raw material quota, raw material code, supplier code, work breakdown structure of the rail vehicle, and scrap rate of the rail vehicle;

[0085] Obtain the quantity of raw materials that should be scrapped by the supplier based on the raw material loss.

[0086] It should be noted that when managing the raw materials of the supplier, due to the personalized customized production of the enterprise, when the same cut parts are used in different projects, the layout drawings will be inconsistent, and the raw material consumption of the bill of material (Bom) for the same cut part is inconsistent, which conflicts with the universality of the bill of material. If the inventory at the supplier is deducted according to the bill of material, there will be problems with inaccurate inventory. Generate the column quantity quota according to the layout drawing, maintain the column quantity deduction quota according to the work breakdown structure (WBS) of the specific column quantity, raw material code, and supplier code. When the production order on the main assembly line is completed (by default, it is considered that the attached cut part production order is also completed), automatically deduct the raw material quota at the supplier according to the column quantity supplier quota. Calculate the inventory at the supplier according to the first-in, first-out method. Automatically calculate and compare the quantity of raw materials that should be scrapped by the supplier and the actual quantity of scrapped materials returned by the supplier according to the scrap rate of the column quantity and the actual quantity of scrap materials returned by the supplier.

[0087] Preferably, the outsourced purchase order is sent to the supplier through the supplier collaboration platform for confirmation of quantity, price, and delivery date. After the supply is completed, a delivery note is printed for delivery. When receiving goods according to the delivery note, it triggers the automatic confirmation of work reporting for the corresponding production order process, and the procurement cost is included in the process cost of the production order. That is, it realizes that the receipt of the purchase order automatically triggers the work reporting of the production order process, and the cost settlement of the purchase order is transferred to the production order.

[0088] Preferably, an invoice list to be developed is generated based on the receipt of the purchase order, and the purchase order, the goods receipt note, and the contract are matched and verified for reimbursement.

[0089] The present invention also provides a rail vehicle, in which the steps of any of the above-mentioned product process outsourcing management methods are adopted in the manufacturing of the rail vehicle.

[0090] The product process outsourcing management system provided by the present invention will be described below. The product process outsourcing management system described below can be mutually referred to with the product process outsourcing management method described above.
