Description

Technical Field

[0001] The present invention relates to the automotive field, and in particular to a method and system for automatically checking a parts list based on a configured BOM. Background Art

[0002] During vehicle development, the bill of materials (BOM) is the core data guiding production. It records the complete composition of the product in a structured form, including the names, quantities, and hierarchical relationships of raw materials, parts, and semi-finished products throughout the entire life cycle of design, process, and manufacturing. It is the core basis for production planning, procurement, cost accounting, and inventory management, and its accuracy directly affects production efficiency and cost control.

[0003] Traditionally, BOM verification is often performed through manual verification methods, which require manually exporting configured BOMs and checking them item by item. However, as vehicle configuration complexity increases, manual verification methods are inefficient, time-consuming, labor-intensive, and error-prone. Differences in engineer skills and the complexity of configuration combinations lead to high verification error rates and significant impacts. Errors in the list can lead to chain reactions such as production stoppages and cost accounting deviations. Summary of the Invention

[0004] In response to the defects in the prior art, the purpose of the present invention is to provide a method and system for automatic verification of parts lists based on a configured BOM, aiming to achieve efficient verification of the accuracy of parts lists by establishing a standardized part number system and combining it with an automated verification process.

[0005] In order to achieve the above-mentioned object of the invention, the present invention adopts the following technical solution:

[0006] According to a first aspect of the present invention, a method for automatically checking a parts list based on a configured BOM is provided, comprising the following steps:

[0007] In step S1, a basic number database is constructed based on the functional structure of the parts, and a standard part number is generated based on the basic number database. The standard part number consists of three parts: a prefix, an infix, and a suffix. The prefix is ​​the first vehicle model for the part, and the suffix is ​​the specific version number of the part. Several functional modules are divided according to the functional structure and assigned basic numbers respectively. The infix of the standard part number is the basic number of the functional module to which the part belongs. Parts of the same functional module use the same infix.

[0008] In step S2, variable condition information is set for the parts in the BOM room based on the part configuration information. The setting rule is as follows: the corresponding eigenvalue code is determined based on the part configuration information, and the three operators, AND, OR, and NOT, are used with the eigenvalue code to form a logical expression that constrains the part usage, which serves as the variable condition for the part; if the part is standard for all models, the variable condition is set to a null value;

[0009] In step S3, the required parts information is input during verification, and the required parts information includes the BOM room where the part to be verified is located, the vehicle model used by the part to be verified, and the part infix;

[0010] In step S4, based on the required parts information, BOM room information, and vehicle configuration information, according to a preset verification method, when it is determined that the required parts exist in the BOM room, a usage and quantity table of the required parts on the corresponding vehicle model is output.

[0011] Preferably, in step S4, all vehicle models that require part information are screened and output according to the variable conditions of the parts.

[0012] According to a second aspect of the present invention, there is provided a system for automatically checking a parts list based on a configured BOM, comprising:

[0013] Storage module, used to store BOM room information and vehicle configuration information;

[0014] The information receiving module is used to receive the required parts information, including the BOM room where the parts to be verified are located, the vehicle model used by the parts to be verified, and the part infix;

[0015] The verification module is used to determine whether the required parts exist in the BOM room according to the required parts information, BOM room information, vehicle configuration information and the preset verification method;

[0016] The output module is used to output the usage and quantity table of the required parts on the corresponding vehicle model when there are required parts in the BOM room.

[0017] Preferably, the verification module screens and instructs the output module to output all vehicle models that have configuration requirement part information based on variable conditions of the parts.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The present invention can greatly improve the accuracy of BOM verification and significantly improve verification efficiency by establishing a standardized part number system, combining a special part variable condition setting method, and coordinating automated matching verification.

All other embodiments obtained by persons of ordinary skill in the art based on the embodiments in the present application without making any creative efforts shall fall within the scope of protection of the present application.

[0025] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0026] Example 1

[0027] This embodiment provides a method for automatically verifying a parts list based on a configured BOM, achieving part number standardization and automated verification of the list's accuracy, thereby improving verification efficiency and accuracy. Automatic parts list verification involves automatically matching part configuration relationships with the dotted relationships in the configuration table on the vehicle model. The method provided in this embodiment includes the following steps:

[0028] In step S1, a basic number database is constructed based on the functional structure of the parts, and a standard part number is formed based on the basic number database. The method for constructing the basic number database is: divide the functional structure of the parts into several functional modules, such as steering wheel, front bumper, etc., and assign a basic number to each functional module to form a basic number database. The basic numbers of different functional modules are different, and the infix of the standard part number is the basic number of the functional module to which the part belongs. The basic number of the functional module is the unique identity code of the functional structure component, which corresponds to the Chinese name of the part. The standardized database established in this step enables the system to quickly identify the function of the part and the applicable scenarios, facilitating the rapid and accurate identification of the part type.

[0029] In this embodiment, a standard part number consists of a prefix, an infix, and a suffix. The prefix refers to the vehicle model the part was first used on, used to trace the original vehicle model the part was compatible with. The infix is ​​the base number corresponding to the part, used to ensure logical consistency among similar parts. The suffix refers to the specific version of the part and can be used to distinguish design iterations. Table 1 shows an example of a standard part number, where the prefix, infix, and suffix are separated by a hyphen.

[0030] Table 1:

[0031] Standard part numbers Part Name PA31-47300-AAW Cargo box sheet metal assembly PA31-47300-BAW Cargo box sheet metal assembly PP6-47300-AAW Cargo box sheet metal assembly PP6-47300-BAW Cargo box sheet metal assembly

[0032] In step S2, variable condition information is set for the parts in the BOM room according to the part configuration information. The setting rules are as follows: determine the characteristic value code according to the part configuration, and use the three operators of AND, OR, and NOT and the characteristic value code to form a logical expression that constrains the usage of the part as the variable condition of the part; if the part is standard for all models, the variable condition is set to a null value.

[0033] Specifically, according to the configuration rules adopted in this embodiment, if a variable condition has only one configuration, it can indicate that the part is used on different vehicle models depending on the configuration. For example, if a part's configuration information indicates that one part is used on a pure electric vehicle, and the characteristic value code for pure electric is AAF004, then the variable condition for the part is set to AAF004, and the usage is set to 1. If the variable condition has multiple configurations, the constraints pointed to by the logical expression can precisely limit the part to optional or standard features on certain vehicle models. For example, if a part's configuration information indicates that one part is used on a pure electric vehicle with a standard rubber cargo box, and the characteristic value code for pure electric is AAF004, and the characteristic value code for the standard rubber cargo box is AAT048, then the variable condition for the part is set to AAF004&AAT048, and the usage is set to 1. Different variable conditions indicate different usages of the part on different vehicle models. The part's usage is determined by the usage, which is the vehicle model defined by the constraint relationship. The variable condition setting rules used in this step use logical expressions to accurately define the scope of use of the parts to specific configured vehicle models, avoiding errors caused by manual judgment, such as installing parts in inappropriate vehicles. At the same time, when the vehicle configuration table or part design changes, only the variable conditions need to be modified to synchronously update the BOM, greatly improving work efficiency. The system automatically parses the variable conditions, replacing manual inspection of configuration combinations one by one, significantly shortening verification time.

[0034] In step S3, during verification, the required parts information is input into the parts verification statistics table, wherein the required parts information includes the BOM room where the parts to be verified are located, the vehicle model used by the parts to be verified, and the part infix.

[0035] In step S4, based on the required part information, BOM room information, and vehicle configuration information, a preset verification method is used to determine if the required part exists in the BOM room. A usage and quantity table for the required part on the corresponding vehicle model is then output. The BOM room information includes the part's standard part number, variable condition information, and usage information.

[0036] The preset verification method primarily includes the following steps: Based on the input part infix, it screens all matching standard part numbers in the BOM room and determines the corresponding variable condition information. Based on the determined variable condition information, it exhaustively screens the matching vehicle configuration information and corresponding usage information in the BOM room to form a usage and quantity table for the required part on the corresponding vehicle model. Users can use this usage and quantity table to verify whether the required part has missing or duplicate usage on some models.

[0037] like Figure 2 As shown, since it is impossible to quickly or accurately identify the specific vehicle model used by a part directly through the constraint relationship, in steps S3 and S4, the specific vehicle model used by the part can be quickly and accurately identified through the part verification statistics page. This embodiment creates a part verification statistics table that can call BOM room information and provides a visual interactive interface for user query.

[0038] For example, after entering the Part Verification Statistics page, the user can enter "Dadao Modified" in the BOM Room field, select "All Models" in the Vehicle Model field, enter "47300" in the Part Infix field, and click Search. The system then searches the corresponding BOM Room for parts that match the part infix based on the BOM Room, vehicle model, and part infix entered by the user. Based on the part's variable conditions (i.e., constraints), it matches the specific configuration models formed by configuration constraints under different vehicle models and outputs them in the form of a statistical table. The usage of the parts in the BOM Room is simultaneously reflected in the specific vehicle models. Engineers use the output statistical table to check the accuracy of part usage and quantity. In the Part Verification Statistics table, part infix information is entered by the user. If the system finds during interaction that the part represented by the part infix information does not exist in the BOM Room, the relevant results will not be output, and the user will be required to re-enter the conditions.

[0039] Furthermore, a vehicle model project may include multiple vehicle models, and a specific configuration vehicle model may be formed depending on whether the configuration is optional. The method provided in this embodiment can also filter and output all vehicle models with configuration requirement part information based on the variable conditions of the parts in step S4 for user verification, thereby improving the efficiency and accuracy of engineer verification.

The verification module, based on the variable conditions of the part, filters and instructs the output module to output all vehicle models configured with the required part information.

[0043] It should be noted that the explanation of various implementation methods and beneficial effects of the method in the above embodiment 1 is also applicable to this embodiment. To avoid redundancy, it will not be expanded here in detail.
