[0051] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0052] A Bill of Materials (BOM) is a technical document describing the composition of a product, indicating the types and quantities of parts required, serving as the data basis for production planning. BOMs are widely used in automotive manufacturing, electronics production, and furniture manufacturing. A complete BOM improves the systematic nature of parts and materials management, enhances production efficiency, and ensures product quality meets design standards and maintains consistency. However, with the rapid development of the manufacturing industry, the types and quantities of parts required for products continue to increase, leading to a gradual increase in the complexity of BOMs. This results in greater time and cost requirements for BOM verification. Currently, the efficiency of technical solutions for verifying BOMs still needs improvement.

[0053] To address the aforementioned issues, this application provides a bill of materials (BOM) inspection method, which involves obtaining a standard BOM room and a project BOM room. The standard BOM room is constructed based on a standard configuration table, and the project BOM room is constructed based on a project configuration table. The method involves assembling the project products corresponding to the project configuration table to obtain the component organization information for the project products. Based on the component organization information, the BOM is extracted from the standard BOM room to obtain a standard BOM. Similarly, based on the component organization information, the BOM is extracted from the project BOM room to obtain a project BOM. Finally, the project BOM is checked for completeness against the standard BOM to obtain the BOM inspection results, which are then used to optimize and rectify the project configuration table.

[0054] The bill of materials (BOM) inspection method provided in this application obtains a standard BOM room constructed based on a standard configuration table and a project BOM room constructed based on a project configuration table. For the project product corresponding to the project configuration table, the component organization information of the project product is obtained through the overall assembly of the components. The standard BOM is extracted from the standard BOM room and the project BOM is extracted from the project BOM room using the component organization information. Finally, the standard BOM is used as the inspection benchmark to perform an integrity check on the project BOM and obtain the BOM inspection result.

[0055] Compared with related technologies, this application extracts the bill of materials from the bill of materials room based on the parts compilation information of any project product corresponding to the project configuration table. This effectively reduces the number of items that need to be compared during integrity checks, reduces the complexity of integrity checks, improves inspection efficiency, and thus improves project production efficiency.

[0056] The bill of materials (BOM) checking methods provided in this manual can be applied to perform completeness checks on the BOM of production projects, such as those for specific car models in the automotive industry. It is understood that, with adaptive modifications, the BOM checking methods provided in this manual can also be applied to production projects in other fields and industries to perform BOM checks on different types of products. These other fields and industries may include electronics manufacturing and furniture manufacturing, among others.

[0057] According to an embodiment of this application, a bill of materials checking method is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0058] Reference Figure 1 As shown, this embodiment provides a bill of materials checking method, which includes:

[0059] S100. Obtain the standard bill of materials room and the project bill of materials room; wherein, the standard bill of materials room is constructed based on the standard configuration table, and the project bill of materials room is constructed based on the project configuration table.

[0060] S200. Assemble the parts of the project products corresponding to the project configuration table to obtain the parts compilation information of the project products.

[0061] S300. Based on the parts organization information, extract the bill of materials in the standard bill of materials room to obtain the standard bill of materials for the project product; based on the parts organization information, extract the bill of materials in the project bill of materials room to obtain the project bill of materials for the project product.

[0062] S400. Perform an integrity check on the project's bill of materials according to the standard bill of materials, and obtain the bill of materials check results for use in optimizing and rectifying the project configuration table.

[0063] The standard configuration table can be obtained by globally managing all parts required for all products based on the standard product structure, serving as a benchmark for bill of materials (BOM) checks. Parts in the standard configuration table can be managed hierarchically and assigned functional location codes, indicating the part's position and corresponding function within the product. Each part also has its own variants, representing the specifications or types used in different products.

[0064] A project configuration table is derived from the planning and configuration of parts required for an actual production project and its products. It can include the types and quantities of parts needed for procurement and production. It should be noted that, under normal circumstances, the types of parts in the project configuration table can be a subset of the types of parts in the standard configuration table, and the range of variations for each part in the project configuration table can be a subset of the range of variations for the corresponding part in the standard configuration table. If the project configuration table contains part types or variations not included in the standard configuration table, it indicates that the project configuration table may contain errors.

[0065] Reference Figure 2 As shown, the standard bill of materials (BOM) room constructed based on the standard configuration table and the project BOM room constructed based on the project configuration table are obtained. The standard BOM room includes multiple global parts and their corresponding global variants. A global part can be any part that is universally applicable across all products, and a global variant can be a part variation of a global part that is universally applicable across all products. Different global variants can be applied to different products. The types of global parts are the same as the types of parts in the standard configuration table, and the range of global variants is the same as the range of variants corresponding to the corresponding parts in the standard configuration table. The project BOM room includes multiple project parts and their corresponding project variants. Project parts can be parts required for a project product, and project variants can be part variations of project parts selected within a project product. Different project variants can be applied to different project products. The types of project parts are the same as the types of parts in the project configuration table, and the range of project variants is the same as the range of variants corresponding to the corresponding parts in the project configuration table.

[0066] In some embodiments, the process of constructing a standard bill of materials (BOM) room may include: determining global parts based on parts in a standard configuration table, and obtaining multiple management fields corresponding to the global parts, including part number, Chinese name of the part, English name of the part, global variant and its description, and functional location code and its description, etc., and storing the obtained information to obtain a standard BOM room. Similarly, the process of constructing a project BOM room may include: determining project parts based on parts in a project configuration table, and obtaining multiple management fields corresponding to the project parts, including part number, Chinese name of the part, English name of the part, project variant and its description, and functional location code and its description, etc., and storing the obtained information to obtain a project BOM room.

[0067] Furthermore, for any project product corresponding to the project configuration table, the required parts and corresponding variants of that project product are obtained, and the parts and variants are assembled as a whole to obtain the part compilation information for that project product. It should be noted that the part compilation information represents the part configuration of the project product. Any project product can have multiple part compilation information to represent different product versions of that project product. Different variants of the same part will not appear in the same part compilation information, and there will be at least one difference in a part or variant between different part compilation information.

[0068] It should be noted that this embodiment can arrange and combine parts and variations to obtain all project products and product versions that the production platform can produce, rather than being limited to products that have already been designed and manufactured. This expands the scope of the bill of materials (BOM) inspection and effectively improves the completeness of the project configuration table. Furthermore, for some product versions, completeness checks can be performed in the early stages of design, improving the timeliness of the checks, reducing potential losses caused by errors in the project configuration table, and ensuring efficient production processes.

[0069] Furthermore, for any product version of the project product, a relationship is established between the field information of each part in the corresponding part compilation information and the global parts in the standard bill of materials room to determine which parts are required and their quantities for that product version's bill of materials, thus obtaining the standard bill of materials for that product version. Similarly, a relationship is established between the field information of each part in the corresponding part compilation information and the global parts in the project bill of materials room to determine which parts are required and their quantities for that product version's bill of materials, thus obtaining the project bill of materials for that product version. It should be noted that both the standard bill of materials and the project bill of materials correspond to the same product version. The project bill of materials only includes parts and variants that appear in both the part compilation information and the project bill of materials room. If a part or variant from the part compilation information does not exist in the project bill of materials room, it means that the corresponding part or variant does not exist in the project bill of materials, and in this case, the project configuration table may be missing the part or variant.

[0070] It is understood that both the standard bill of materials (BOM) and the project bill of materials (BOM) are bills of materials for a single product version of the project product. Compared with the BOMs established in related technologies that correspond to all project products, the standard BOM and the project BOM in this embodiment contain fewer entries, and each entry corresponds to only one part or variant, which effectively reduces the complexity of the BOM, thereby reducing the complexity of subsequent integrity checks and effectively improving the efficiency of BOM checks.

[0071] Furthermore, based on the standard bill of materials (BOM) for any product version, a completeness check is performed on the project BOM for that product version. Multiple entries in the standard BOM and the project BOM are compared item by item, and the BOM check result is obtained based on the differences between the two for each entry. It can be understood that if every entry in the project BOM is identical to the corresponding entry in the standard BOM, it means that the project configuration table covers that product version, and the BOM for that product version is complete. If a completeness check is performed on all product versions of all project products, and the BOM for each product version is determined to be complete, a BOM check result indicating that the project configuration table is complete is obtained. If the BOM for any product version is incomplete, a BOM check result indicating that the project configuration table is incomplete is obtained. In this case, the project configuration table needs to be modified according to the BOM check result to ensure its completeness.

[0072] The bill of materials (BOM) inspection method provided in this embodiment obtains a standard BOM room constructed based on a standard configuration table and a project BOM room constructed based on a project configuration table. For the project product corresponding to the project configuration table, the component assembly information of the project product is obtained through the overall assembly of the components. The standard BOM is extracted from the standard BOM room and the project BOM is extracted from the project BOM room using the component assembly information. Finally, the standard BOM is used as the inspection benchmark to perform an integrity check on the project BOM and obtain the BOM inspection result.

[0073] Compared with related technologies, this application extracts the bill of materials from the bill of materials room based on the parts compilation information of any project product corresponding to the project configuration table. This effectively reduces the number of items that need to be compared during integrity checks, reduces the complexity of integrity checks, improves inspection efficiency, and thus improves project production efficiency.

[0074] Reference Figure 3 As shown, in one embodiment of this application, the standard bill of materials room includes multiple global parts and their respective global variants; the global variants corresponding to the multiple global parts are determined in the following way:

[0075] S110. Perform technical feature analysis on any one of the multiple global parts to determine the variant driving elements of any one global part.

[0076] S120. Constrain and combine the variant driving elements of any global part to obtain the global variant of any global part.

[0077] Among these, the variant-driving factors for a global component can be the technical features that make the global component competitive in the market. By optimizing and adjusting the technical features of the global component, multiple global variants corresponding to the same global component can be obtained. For the same global component, each global variant has different technical features, enabling products using different global variants to have different competitive advantages in the market.

[0078] Specifically, when constructing a standard bill of materials room, the variant-driving factors for any global component are determined by performing a technical feature analysis on that component. This technical feature analysis can be conducted through module discussions or market analysis, focusing on marketing requirements, product definitions, or technological upgrades to identify the technical features that make the global component competitive in the market, serving as the variant-driving factors.

[0079] Furthermore, any global part can correspond to multiple variant driving elements, and each variant driving element can correspond to multiple variant specifications. Variant specifications corresponding to the same variant driving element are mutually exclusive and cannot be used simultaneously on the same global part. Based on the constraints and combination rules between different variant driving elements, the variant specifications corresponding to multiple variant driving elements are arranged and combined to obtain multiple global variants of that global part. It should be noted that the global variants of a global part correspond to the product's development platform and are universal on that platform. The same global part may have different global variants on different development platforms. After obtaining the global variants of a global part for any development platform, when planning a project on that platform, the variant used by the project product can be directly selected from the existing global variants without redeveloping the variant, thus reducing the development cost of part variants.

[0080] For example, taking the power battery pack as a global component, its variant driving elements can include battery pack calorie rating and battery pack size, etc. The battery pack calorie rating can correspond to 8 variant specifications, and the battery pack size can correspond to 3 variant specifications. By optimizing and adjusting the battery pack calorie rating and battery pack size respectively, 24 global variants corresponding to different battery pack calorie ratings and battery pack sizes can be obtained.

[0081] Reference Figure 4 As shown, in one embodiment of this application, the project products corresponding to the project configuration table are assembled into a whole to obtain the component information of the project products, including:

[0082] S210. Obtain the product parts used in the project product and their corresponding product variations to form the part configuration information of the project product.

[0083] S220. Based on part assembly constraints, the project products are assembled according to the part configuration information to obtain multiple assembly variants of the project products.

[0084] S230. Perform assembly definition coding on any assembly variant among multiple assembly variants to obtain the component assembly information of the project product.

[0085] Specifically, based on the product parts used in the project product and the corresponding product variants for each product part, the part configuration information of the project product is determined to define the assembly scope of the project product. For each product part in the part configuration information, a variant is selected, and the selected product variants are combined and assembled based on part assembly constraints to obtain multiple assembly variants using different part variants. Each assembly variant corresponds to a product version of the project product, and there is at least one difference in product variants between each product version.

[0086] Furthermore, for any assembly variant among multiple assembly variants, an assembly definition code is performed based on the feature code of each product variant in that assembly variant to obtain the part assembly information of that assembly variant, indicating which product variants were used in that assembly variant.

[0087] For example, when the product is a vehicle, the product parts may include chassis hubs and steering wheels. The chassis hubs may include two product variations: one made of steel and the other of aluminum alloy. The material of the chassis hub is represented by ZB00, with the steel variation represented by ZD01 and the aluminum alloy variation by ZD02. The steering wheel may include two product variations: one without steering wheel heating and the other with steering wheel heating. The heating function of the steering wheel is represented by KB00, with the non-heating variation represented by KB01 and the heating variation by KB02. Therefore, the project product corresponds to 4 assembly variants. The above 4 assembly variants are defined and coded respectively to obtain the part encoding information corresponding to each assembly variant, namely ZB00=ZB01 AND KB00=KB01, ZB00=ZB02 AND KB00=KB01, ZB00=ZB01 AND KB00=KB02 and ZB00=ZB02 AND KB00=KB02.

[0088] Reference Figure 5 As shown, in one embodiment of this application, the parts organization information includes the product parts used in the project product and their corresponding product variations; based on the parts organization information, the bill of materials is extracted in the standard bill of materials room to obtain the standard bill of materials for the project product, including:

[0089] S310. For any product part used in the project product, compare the configuration of the product variant corresponding to any product part with the global variant corresponding to each global part in the standard bill of materials room to determine the first part that meets the configuration conditions and its corresponding first variant.

[0090] S320. Generate a standard bill of materials for the project product based on the first variant and the assembly quantity corresponding to the first variant.

[0091] Specifically, for any product version of the project product, after inputting the part organization information, a configuration comparison is performed in the standard bill of materials room based on the product variants corresponding to each product part in the part organization information to find the global variant that is the same as that product variant from the standard bill of materials room. If the same global variant is found, the global variant is taken as the first variant, and the global part corresponding to the global variant is taken as the first part.

[0092] Furthermore, the assembly quantity of any part in each product is usually fixed; therefore, in the standard bill of materials (BOM) room, global parts can correspond to preset assembly quantities. Correspondingly, the first part also corresponds to a preset assembly quantity, representing the quantity of the first variant required in the product. After determining the first part and the first variant, a standard BOM for that product version is generated based on the first variant and the assembly quantity corresponding to each first variant. If a product part in the part compilation information cannot find the same global part in the standard BOM room, the entry for that product part is set to empty.

[0093] Understandably, the standard bill of materials (BOM) is derived from the standard BOM room and is used to fully represent the part types and quantities corresponding to any product version of the project product, serving as a benchmark for integrity checks. If any entry in the standard BOM is empty, it means that the global part corresponding to that entry does not exist in the standard BOM room. In this case, it is necessary to check both the standard configuration table and the part configuration information of the project product to determine the cause of the error.

[0094] Reference Figure 6 As shown in one embodiment of this application, the project bill of materials room includes multiple project parts and their corresponding project variants. The part compilation information includes the product parts used in the project product and their corresponding product variants. Based on the part compilation information, the bill of materials is extracted in the project bill of materials room to obtain the project bill of materials for the project product, including:

[0095] S330. For any product part used in the project product, compare the configuration of the product variant corresponding to any product part with the project variant corresponding to each project part in the project bill of materials room to determine the second part that meets the configuration conditions and its corresponding second variant.

[0096] S340. Generate the project bill of materials for the project product based on the second variant and the assembly quantity corresponding to the second variant.

[0097] Specifically, for any product version of the project product, after inputting the part compilation information, a configuration comparison is performed in the project bill of materials room based on the product variants corresponding to each product part in the part compilation information to find the project variant that is the same as that product variant. If the same project variant is found, that project variant is taken as the second variant, and the project part corresponding to that project variant is taken as the second part.

[0098] Furthermore, in each product, the assembly quantity of any part is usually fixed; therefore, in the project bill of materials room, project parts can correspond to a preset assembly quantity. Correspondingly, the second part also corresponds to a preset assembly quantity, representing the quantity of the second variant required in the product. After determining the second part and the second variant, the project bill of materials for that product version is generated based on the second variant and the assembly quantity corresponding to each second variant. If the product part in the part compilation information cannot be found in the project bill of materials room, the entry for that product part is set to empty.

[0099] It is understandable that the project bill of materials is derived from the project bill of materials room. If any item in the project bill of materials is empty, it means that the project part corresponding to that item does not exist in the project bill of materials room, and the project configuration table is missing, which needs to be corrected accordingly.

[0100] Reference Figure 7 As shown in this embodiment of the application, the standard bill of materials includes multiple standard part types and their corresponding quantities, while the project bill of materials includes multiple parts to be inspected and their corresponding quantities. The project bill of materials is then checked for completeness based on the standard bill of materials to obtain the bill of materials check results, including:

[0101] S410. Compare multiple standard part types with multiple parts to be inspected to obtain part type comparison results.

[0102] S420. For the same standard part type and the part type to be inspected, compare the corresponding number of standard parts and the number of parts to be inspected to obtain the part quantity comparison result.

[0103] S430. Obtain the bill of materials inspection results based on the part type comparison results and the part quantity comparison results.

[0104] Specifically, the integrity check is performed on any given product version. During the integrity check, the part types and quantities are compared against the standard bill of materials (BOM) for that product version and against the project BOM for that product version. The part type comparison involves comparing the standard part types in the standard BOM with the part types to be checked in the project BOM to check the part type configuration of the project configuration table for that product version, thus obtaining the part type comparison results. If all standard part types correspond one-to-one with all part types to be checked, it means that the part types in the standard BOM and the project BOM are the same, and the part type configuration of the project configuration table for that product version is complete.

[0105] Furthermore, the part quantity comparison can be performed by comparing the standard part quantities in the standard bill of materials (BOM) with the parts to be inspected in the project BOM for the same part type. This comparison checks the part quantity configuration of the project configuration table for any product version, yielding the part quantity comparison results. If the standard part quantities and parts to be inspected are the same for all part types, it indicates that the quantities of all part types in the standard BOM and the project BOM are identical, and the part quantity configuration of the project configuration table for any product version is accurate. If the standard part quantities and parts to be inspected differ for any part type, it indicates that there is an error in the part quantity configuration of that part type in the project configuration table, and appropriate corrections are required.

[0106] Furthermore, the results of the part type comparison and part quantity comparison are integrated to obtain the bill of materials (BOM) inspection results. After obtaining the BOM inspection results, discrepancies are analyzed to identify errors in the project configuration table, and these errors are rectified to ensure the integrity of the project configuration table.

[0107] Reference Figure 8 As shown, in one embodiment of this application, multiple standard part types are compared with multiple parts to be inspected to obtain part type comparison results, including:

[0108] S412. If any one of the multiple standard part types is different from all the multiple parts to be inspected, it is determined that the bill of materials for the project is missing a part corresponding to any one of the standard part types.

[0109] S414. If any one of the multiple types of parts to be inspected is different from multiple standard parts types, it is determined that there is redundancy in the bill of materials for any standard parts type.

[0110] Specifically, if any one of the standard part types differs from all the other part types to be inspected, it means that the part corresponding to that standard part type is not included in the project's bill of materials, i.e., the part corresponding to that standard part type is missing from the project configuration table. In this case, the part corresponding to that standard part type needs to be added to the project configuration table to avoid the part being missing during production.

[0111] Furthermore, if any of the multiple inspected part types differs from all the standard part types, it indicates that the part corresponding to that inspected part type does not belong to the standard bill of materials, meaning that the part corresponding to that inspected part type does not exist in the standard configuration table. In this case, the part corresponding to that inspected part type needs to be deleted from the project configuration table to avoid unnecessary costs in the production process.
