[0079] S203: The special loading part list is checked to determine the existence of specific detail data, and the loading BOM data is traversed to determine whether the specific detail data exists:

[0080] If not, the part details of the initial trial BOM are updated to obtain the initial trial BOM;

[0081] If so, the sample vehicle configuration data of the initial trial BOM is updated to obtain the initial trial BOM.

[0082] That is, it is checked whether the detail data of OP_TYPE=10 or OP_TYPE=20 exists in the special loading part list, and then the loading BOM data is traversed to determine whether the detail data exists in the loading BOM data. If not, the part details of the initial trial BOM are updated. If so, the sample vehicle configuration data of the initial trial BOM is updated. The specific detail data in the present application is OP_TYPE=10 or OP_TYPE=20, or part detail data formulated according to actual needs.

[0083] Further, in an embodiment, after the initial trial BOM is generated, it further includes: for the generated initial trial BOM, each assembly engineer is assigned according to the process route to actively confirm whether the initial trial BOM needs to be adjusted, and when no adjustment is needed, the initial trial BOM is released.

The related attributes (such as delivery level, professional teacher, joint part information, reduction information, etc.) in the trial BOM preparation process rely on manual judgment and checking, which has low preparation efficiency and poor data accuracy and integrity; 3. The process joint parts and reduction parts involved in the trial BOM need to be manually judged and merged, which has low data accuracy and is easy to cause assembly part redundancy.

[0091] The model-driven whole vehicle trial production BOM automatic preparation method of the embodiments of the present application can standardize BOM data input accuracy, establish an online four-level management and control system of machine installation BOM, trial production BOM, PBOM and single vehicle PBOM, greatly improve the BOM data accuracy and integrity in the whole vehicle trial production stage, and automatically generate trial production BOM and PBOM by referring to a model database, thereby improving the preparation efficiency of trial production BOM and PBOM, improving the BOM database accuracy by using a process assembly or a reduced configuration scheme library, reducing BOM redundant data, and improving the disposal efficiency and data accuracy of BOM. The model-driven automatic generation of process assemblies and reduced configuration schemes can reduce the vehicle repair rate caused by poor input standardization and accuracy of trial production BOM, improve the trial production plan achievement rate and delivery quality, and reduce unnecessary parts procurement and single vehicle trial production cost.
