[0025] It's important to note that RPA (Robotic Process Automation) is a technology that uses software to automate business processes based on specified rules and procedures. This assists or replaces manual tasks, freeing employees from low-value labor. It supports 24 / 7 operation, 365 days a year. Furthermore, RPA has a natural advantage in integrating with AI, achieving automation of highly complex and demanding processes through the fusion of AI technologies such as OCR and Chatbots.

[0026] Vehicle exterior components: These are the visible parts of a car's exterior that directly affect its appearance and visual appeal. These components not only relate to the vehicle's aesthetics but are also often closely linked to the brand image, market positioning, and consumer purchasing decisions. They mainly include: body panels, front and rear bumpers and trim pieces, lights, wheels and rims, rearview mirrors and exterior trim pieces, etc.

[0027] MBOM (Bill of Materials): Based on the basic information of components in EBOM (Bill of Materials), the BOM is reconstructed, defining manufacturing parameters such as process assembly, component routes, and effective time, and then generating the BOM.

[0028] Function code: refers to the code used to express the function and location of a component.

[0029] Existing technical solutions first preprocess the EBOM and MBOM, including data cleaning and range alignment. Then, using part numbers and parent part numbers, they systematically identify structural differences and the presence or absence of differences between the two, and compare attribute values ​​between identical parts based on attributes such as quantity and configuration variables. This method can also perform combined analysis of multiple attributes to uncover deeper-level correlations. Finally, all differences are summarized to generate a structured difference report table. This invention, through hierarchical and multi-faceted automated comparison, significantly improves the efficiency of BOM difference analysis while ensuring comprehensiveness and accuracy.

[0030] The existing technical solution specifically includes the following steps: 1. Data download and standardization preprocessing ① Download the Engineering Bill of Materials (EBOM) and Manufacturing Bill of Materials (MBOM) for the target vehicle model.

[0031] ② Perform data cleaning on both lists: merge duplicate parts (replace multi-line displays with quantity statistics).

[0032] ③ Perform initial consistency processing on the two lists to ensure that they contain the same range of parts, laying a consistent foundation for subsequent comparison.

[0033] 2. Identify structural relationships and differences in the existence of parts. ① Based on the hierarchical structure identification field of the part (part number and its parent part number), analyze the differences in parent-child relationships in EBOM and MBOM, identify and record structural difference data (i.e. the same part may have different superior assembly relationships in different lists).

[0034] ② Based on the part number itself, identify parts that exist only in the EBOM or only in the MBOM, and obtain part difference information (i.e. whether the part has differences).

[0035] 3. Traverse layer by layer and compare the differences in core attributes. ① In the part pairs where both the parent part number and the part number match, a traversal comparison is performed based on the preset difference attributes to be analyzed (such as quantity, configuration variables, etc.).

[0036] ② Identify parts pairs with differences in these attribute parameters and classify them as "difference data"; those with completely identical attribute parameters are classified as "coexisting data".

[0037] 4. Perform refined difference analysis of multiple attribute combinations. ①The “coexisting data” (i.e., parts pairs with the same attribute) obtained in the previous step are combined with another attribute to be analyzed (the latter attribute) for a second traversal analysis.

[0038] ② Identify part pairs that share the same first attribute but differ in the second. This enables a more refined insight into differences by combining two or more attributes.

[0039] 5. Summarize and generate structured difference reports ① Summarize the structural difference data, part difference information and various difference data identified in all the above steps.

[0040] ②Using the hierarchical structure identification fields (part number, parent part number) as the main sorting criteria, establish a clear and structured difference data table as the final difference analysis report.

[0041] In this embodiment of the application, an exterior parts list is obtained based on the MBOM list, exterior parts are filtered by comparing with the exterior parts list library, version differences are compared, and a difference report is generated, thereby achieving efficient and accurate management of changes to vehicle exterior parts.

[0042] Furthermore, the method also includes the following steps: When the information of any of the aforementioned exterior parts list changes, the exterior parts list library is updated synchronously.

[0043] Furthermore, the inventory of exterior parts is stored in a preset shared address.

[0044] Furthermore, the appearance component difference table includes information on upgraded appearance components, information on newly added appearance components, and information on canceled appearance components.

[0045] Furthermore, the method also includes the following steps: If the current version of the exterior parts list corresponding to the target vehicle model is the first version of the exterior parts list of the target vehicle model, then the type of each exterior part is identified as single signal or multiple models.

[0046] The key technical points of the technical solution based on the embodiments of this application are as follows: ① An automated analysis process that integrates RPA with specific business rules: The RPA (Robotic Process Automation) technology was creatively applied to the business scenario of "vehicle appearance part difference calculation and analysis". The robot simulated the complete end-to-end operation of logging into the system, downloading data, and performing calculation and comparison analysis.

[0047] ② Dynamic calculation method based on the "MBOM-Appearance Parts List Library" dual list: The core logic of the technical solution is to use the "exterior parts list library" predefined by the business department as the calculation and screening standard (based on function code or function code name) to match and calculate the screening with the downloaded vehicle model MBOM, thereby accurately locating the set of exterior parts for the vehicle model, which serves as a reference for comparison in subsequent versions.

[0048] ③ Automatic calculation, recognition, and intelligent classification algorithm for multiple version differences: It can automatically retrieve historical version data, compare the current version with the historical version of the appearance parts list, and automatically calculate and identify the difference type (upgrade, addition, cancellation) according to preset rules (such as part name, appearance part version number (change mark)), so as to achieve refined and structured output of differences.

[0049] ④ Integrated closed-loop management architecture of "analysis-backup-notification": The technical solution goes beyond analysis and integrates automatic data backup (original MBOM, discrepancy results) and automatic result push (email notification) functions, forming a complete, traceable, and collaborative business loop.

[0050] Furthermore, the technical protection points of this application embodiment are as follows: ①Automatic analysis and calculation method for differences in vehicle exterior parts based on RPA technology: It covers the complete methodology and workflow from logging into the target system to download the vehicle model MBOM, to filtering the list of exterior parts, to version comparison, difference extraction, difference type identification and marking, and data backup and feedback.

[0051] ② Techniques for calculating and filtering the appearance parts list in MBOM based on the appearance parts list library: Referencing the exterior parts list library, a method is used to automatically calculate and filter the current version of the exterior parts list in the vehicle model MBOM list by function code or function code name.

[0052] ③Technology for comparing and calculating differences in the list of exterior parts: The comparison calculation method differs between the first and non-first version vehicle data, and the technology for generating a list of differing exterior parts.

[0053] ④ Automatic calculation, identification, and marking technology for differences in appearance parts: A method for automatically calculating, identifying, and marking the difference types (upgrade, addition, cancellation, etc.) of parts in the difference list.

[0054] In summary, the technical solutions of this application embodiment have the following technical effects: Empowering Efficiency Improvement: Automating the entire process of appearance component analysis replaces repetitive manual operations, freeing up manpower.

[0055] Ensure reliable results: By standardizing the analysis process, human error is fundamentally eliminated, guaranteeing the quality of output.

[0056] Accelerate product iteration: Supports simultaneous calculation and comparison of multiple versions, quickly locates differences, and helps improve R&D efficiency.

[0057] Achieving closed-loop management: By combining data backup and instant notifications, a traceable and easily collaborative analysis closed loop has been built.
