Description

Technical Field

[0001] This application relates to the field of data processing technology, and in particular to a method, system, equipment and medium for controlling process components. Background Technology

[0002] In the modern automotive manufacturing sector, product structures are highly complex, the number of parts is enormous, and vehicle configurations are becoming increasingly diverse, leading to more frequent engineering changes. Traditional production management models typically involve mainline workstations directly handling the assembly of tens of thousands of individual parts. This results in the mainline assembly cycle time being limited by the complexity of handling these individual parts, hindering overall production efficiency. To address these challenges, related technologies have gradually introduced process assembly as a static, modular management approach. By moving some assembly tasks to sub-assembly lines, the complexity of mainline assembly is reduced. However, these process assembly control methods suffer from inefficient process bill of materials (BOM) management, leading to sluggish system response and insufficient flexibility, failing to meet the requirements of efficient and lean modern production. Summary of the Invention

[0003] This application provides a method, system, equipment, and medium for controlling process components, which solves the technical problem of inefficient control of process bill of materials in related technologies and achieves the technical effect of improving the production efficiency of automobile final assembly.

[0004] To achieve the above objectives, the main technical solutions adopted in this application include: In a first aspect, embodiments of this application provide a method for managing process assemblies, the method comprising: acquiring product configuration information, component master data, and an engineering bill of materials; constructing an initial process bill of materials based on the engineering bill of materials and the component master data; generating corresponding process configuration information based on the product configuration information; determining at least one process assembly based on the initial process bill of materials, the process assembly being used to characterize a combination of parts pre-assembled on a sub-assembly line; and updating the initial process bill of materials based on the process configuration information and the at least one process assembly to generate a target process bill of materials for guiding manufacturing execution.

[0005] The process assembly control method provided in this application ensures the accuracy of process data sources by constructing an initial process bill of materials consistent with the engineering bill of materials. By mapping product configuration information to process configuration information, it achieves efficient conversion of market demand into precise manufacturing instructions. By defining process assemblies and integrating process configurations with process assemblies to generate target process bills of materials, it realizes the encapsulation and reconfiguration from discrete parts to manufacturing modules, thereby streamlining the data flow from design and process to manufacturing. Overall, it achieves the technical effects of improving production efficiency, optimizing spatial layout, and supporting modular parallel production.

[0006] Optionally, determining at least one process assembly based on the initial process bill of materials includes: in response to a user selection instruction, determining at least one part entry in the initial process bill of materials; and constructing the process assembly based on the at least one part entry.

[0007] By responding to user (e.g., process engineer) interaction commands, specific part items are selected from the initial process bill of materials and constructed into process assemblies. This transforms the engineer's manufacturing knowledge and experience into a standardized data structure that can be recognized and processed by a computer, providing an accurate data foundation for subsequent modular delivery, parallel assembly, and production optimization.

[0008] Optionally, based on the process configuration information and the at least one process assembly, the initial process bill of materials is updated to generate a target process bill of materials for guiding manufacturing execution, including: determining material options in the initial process bill of materials that match the current production task according to the process configuration information; creating a process assembly node in the initial process bill of materials that matches the at least one process assembly; and generating the target process bill of materials based on the material options and the process assembly node.

[0009] By creating process assembly nodes in the initial process bill of materials, scattered parts are packaged together, optimizing the assembly structure and providing a data foundation for subsequent modular delivery and parallel operations. By integrating the filtered material set and the reconstructed process assembly nodes, the data flow from design and process to manufacturing is streamlined, achieving a unique and reliable source of manufacturing instructions at the data level, and providing core assurance for the precise, collaborative, and efficient operation of the production line.

[0010] Optionally, the method further includes: in response to a process change request, determining a target process assembly affected by the process change request; updating the sub-assembly list of the target process assembly based on the changes in the process change request; and updating the process assembly node in the target process bill of materials that matches the target process assembly based on the updated sub-assembly list.

[0011] Update the sub-assembly list according to the process change request, and update the corresponding process assembly node synchronously according to the updated sub-assembly list to ensure data consistency, ensure that the target process bill of materials is a single reliable source, prevent material mismatch, production line stoppage and quality defects caused by data inconsistency, and ensure the continuity and reliability of the manufacturing process.

[0012] Optionally, updating the sub-assembly list of the target process assembly includes: performing at least one operation of adding, deleting, or replacing part entries in the sub-assembly list.

[0013] By adding, deleting, and modifying the parts in the sub-assembly list, precise online maintenance of process components is achieved, ensuring timely response to engineering changes. This ensures real-time synchronization between manufacturing instructions and design intent from the data source, avoiding material mismatch, quality defects, and production line stoppages caused by delayed or incorrect change information.

[0014] Optionally, the method further includes: performing creation, modification, or deletion operations on process assembly nodes in the target process bill of materials; and / or associating auxiliary materials or plates specified in a preset resource library with the corresponding material options in the target process bill of materials.

[0015] By precisely linking the auxiliary materials and sheet metal in the preset resource library with the target process material list, the consumable resources that are necessary in the manufacturing process but not defined in the design stage are included, bridging the gap between design data and manufacturing reality, ensuring the integrity and executability of manufacturing instructions, and thus eliminating production interruptions, quality fluctuations and operational chaos caused by missing or unclear specifications of auxiliary materials at the source.

[0016] Optionally, the method further includes: constructing an initial manufacturing bill of materials (BOM) based on the target process BOM and the vehicle code; generating a factory process document based on the target process BOM and manufacturing resource information, wherein the manufacturing resource information includes manufacturing equipment, tooling fixtures, and factory layout information; and updating the initial manufacturing BOM based on the workstation information in the factory process document to generate a complete manufacturing BOM for use in an enterprise resource planning system.

[0017] By combining the target process bill of materials (BOM) with the vehicle code, a general process solution is transformed into a unique initial manufacturing BOM required for a specific vehicle. Based on the assembly logic defined in the target process BOM and the physical constraints described by the manufacturing resource information, a process plant file is generated, thereby assigning abstract assembly tasks to specific workstations with corresponding capabilities. By associating and integrating the workstation information in the plant process file with the initial manufacturing BOM, precise binding between materials and geographical locations is achieved, generating a complete manufacturing BOM that drives efficient enterprise operations. This ensures a single, reliable source, thereby breaking down data barriers from process design to production execution, logistics, and cost accounting, and guaranteeing the efficient and reliable operation of the manufacturing system.

[0018] Secondly, embodiments of this application provide a management and control system for process assemblies. The system includes: an acquisition module for acquiring product configuration information, component master data, and an engineering bill of materials (OBM); a construction module for constructing an initial process BOM based on the BOM and the component master data; a generation module for generating corresponding process configuration information based on the product configuration information; a determination module for determining at least one process assembly based on the initial process BOM, wherein the process assembly represents a combination of parts pre-assembled on a sub-assembly line; and an update module for updating the initial process BOM based on the process configuration information and the at least one process assembly to generate a target process BOM for guiding manufacturing execution.

[0019] Thirdly, embodiments of this application provide a computer device, including: a memory and a processor, wherein the memory and the processor are communicatively connected to each other, the memory stores computer instructions, and the processor executes the computer instructions to perform the above-described process assembly control method.

[0020] Fourthly, embodiments of this application provide a computer-readable storage medium storing computer instructions, which are used to cause a computer to execute the above-described process assembly control method.

[0021] Fifthly, embodiments of this application provide a computer program product, including computer instructions, which are used to cause a computer to execute the above-described process assembly control method. Attached Figure Description

Detailed Implementation

[0024] 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.

[0025] In the modern automotive manufacturing industry, product structures are extremely complex, involving tens of thousands of parts. The traditional production management model involves mainline workstations directly handling all these individual parts, picking and assembling them one by one. This model has several inherent drawbacks: First, the mainline workstations handle a massive number of parts, making operations complex and prone to errors, and resulting in excessively long vehicle assembly times on the mainline, severely hindering production cycle speed. Second, the material containers required for a large number of parts occupy enormous space alongside the mainline, leading to crowded workshop layouts and complex, inefficient logistics distribution paths. Third, quality inspection checkpoints are typically located on the mainline, and defective parts can easily flow into the mainline assembly stage, causing rework or even line stoppages, resulting in high quality costs. Furthermore, the automotive industry features rapid model iterations, diverse configurations, and frequent engineering changes. A change to a single part often has far-reaching consequences. In the existing management system, the consumption of old materials, the switching to new materials, and supply chain coordination lack precise "breakpoint" management down to the second, easily leading to incorrect or missing material loading or production interruptions. Meanwhile, the poor flow of change information between design and manufacturing departments makes it difficult to guarantee a single, reliable source of product data, and also hinders the accurate tracing and rapid containment of defects. To address these complexities, the industry has seen the emergence of solutions using "process assembly BOMs." This involves transferring the assembly work of multiple parts to sub-assembly lines, forming an independent "process assembly" module, which is then assembled on the main line. This method acts as a bridge between design and manufacturing, achieving a degree of production standardization and avoiding production stoppages caused by uncoordinated changes through assembly change management.

[0026] However, the relevant process component control methods still have significant shortcomings: First, the creation, maintenance, and version management of process BOMs are inefficient and lack efficient linkage with engineering BOMs; Second, the change process (whether initiated by design or process) has failed to achieve full integration of information and data flows, the approval process is cumbersome, and inter-departmental collaboration is difficult, resulting in slow change response, weak risk control capabilities, and an inability to meet the stringent requirements of modern automotive manufacturing for high efficiency, high flexibility, and low cost control.

[0027] Therefore, there is an urgent need in this field for a new method that can achieve refined, digital, and collaborative management and control of the entire lifecycle of process components.

[0028] The process assembly control method provided in this application can be applied to the process management system. By constructing a data flow framework that connects design, process and manufacturing, it solves the problems of slow production cycle, crowded line space and low logistics efficiency caused by the main assembly line directly facing a large number of loose parts.

[0029] This application provides a method for controlling process components. 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. Also, 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.

[0030] Please refer to Figure 1 , Figure 1 A flowchart illustrating a method for controlling a process assembly, as provided in this application embodiment, is shown below. Figure 1 As shown, the process includes the following steps: Step S1: Obtain product configuration information, component master data, and engineering bill of materials.

[0031] Product configuration information is market- and customer-oriented, describing the final state and functionality of the product. This information may include vehicle model, engine displacement, drive type, and whether a sunroof is included. Part master data (Part) is a dataset of core attributes describing the basic, shared, and unique identity of a part. This may include part number, part name, material, and weight. The engineering bill of materials (BOM) is an engineering-oriented list of parts, describing a structured list of components that make up the product. Product configuration information, part master data, and the engineering BOM can be obtained from the R&D data management system.

[0032] Step S3: Based on the engineering bill of materials and the component master data, construct an initial process bill of materials.

[0033] The initial process bill of materials is a process-oriented bill of materials that inherits the product structure of the engineering bill of materials in the R&D data management system and associates and populates the core attributes in the master data of components to enrich the node information, thus avoiding material errors or assembly errors caused by data inconsistency.

[0034] Step S5: Generate corresponding process configuration information based on the product configuration information.

[0035] Process configuration information is a manufacturing instruction oriented towards a specific process. It is obtained by referencing product configuration information and supplementing it with specific configuration information related to manufacturing resources and plant layout.

[0036] Step S7: Based on the initial process bill of materials, determine at least one process assembly, which is used to characterize the combination of parts to be pre-assembled on the assembly line.

[0037] A process assembly is a single, complete module or sub-component pre-assembled from multiple logically or physically related parts on an assembly line. Process assemblies for pre-assembly are identified from the initial process bill of materials (PBOM). By defining process assemblies, the assembly relationships of a large number of individual parts are encapsulated within them. The mainline workstations only need to handle a much smaller number of assemblies, greatly simplifying mainline operations and shortening vehicle assembly time on the mainline.

[0038] Step S9: Based on the process configuration information and the at least one process assembly, update the initial process bill of materials to generate a target process bill of materials to guide manufacturing execution.

[0039] The initial process bill of materials (BOM) is a static basic data structure. By incorporating process configuration information, the target process BOM can generate specific manufacturing instructions based on different product configurations. By incorporating process assemblies, the target process BOM establishes the division of labor between the sub-assembly line and the main line in the data structure, thereby providing data basis for shortening the main line cycle time, optimizing the line layout, and improving material efficiency.

[0040] The process assembly control method provided in this application ensures the accuracy of process data sources by constructing an initial process bill of materials consistent with the engineering bill of materials. By mapping product configuration information to process configuration information, it achieves efficient conversion of market demand into precise manufacturing instructions. By defining process assemblies and integrating process configurations with process assemblies to generate target process bills of materials, it realizes the encapsulation and reconfiguration from discrete parts to manufacturing modules, thereby streamlining the data flow from design and process to manufacturing. Overall, it achieves the technical effects of improving production efficiency, optimizing spatial layout, and supporting modular parallel production.

[0041] In some specific embodiments, determining at least one process assembly based on the initial process bill of materials includes: in response to a user selection instruction, determining at least one part entry in the initial process bill of materials; and constructing the process assembly based on the at least one part entry.

[0042] By responding to user (e.g., process engineer) interaction commands, specific part items are selected from the initial process bill of materials and constructed into process assemblies. This transforms the engineer's manufacturing knowledge and experience into a standardized data structure that can be recognized and processed by a computer, providing an accurate data foundation for subsequent modular delivery, parallel assembly, and production optimization.

[0043] In some specific embodiments, updating the initial process bill of materials (BOM) based on the process configuration information and the at least one process assembly to generate a target process bill of materials (BOM) for guiding manufacturing execution includes: determining material options in the initial process bill of materials that match the current production task based on the process configuration information; creating a process assembly node in the initial process bill of materials that matches the at least one process assembly; and generating the target process bill of materials based on the material options and the process assembly node.

[0044] Process configuration information characterizes the material selection rules under a specific product configuration. Based on the process configuration information, a set of material options matching the current production task is selected from the initial process bill of materials, ensuring that only the necessary parts for that configuration are delivered and installed along the production line, avoiding the risk of incorrect or missing parts. By creating process assembly nodes in the initial process bill of materials, scattered parts are encapsulated, optimizing the assembly structure and providing a data foundation for subsequent modular delivery and parallel operations. By merging the selected material set and the reconstructed process assembly nodes, the data flow from design and process to manufacturing is streamlined, achieving a unique and reliable source of manufacturing instructions at the data level, providing a core guarantee for the precise, collaborative, and efficient operation of the production line.

[0045] In some specific embodiments, the method further includes: in response to a process change request, determining a target process assembly affected by the process change request; updating the sub-assembly list of the target process assembly based on the changes in the process change request; and updating the process assembly node in the target process bill of materials that matches the target process assembly based on the updated sub-assembly list.

[0046] A target process assembly refers to a process assembly itself or its subordinate parts that is affected by a change request. One scenario is that the change request directly requests modification of the process assembly itself, for example, requesting a change to the assembly sequence of a "door assembly". Another scenario is that the change request targets a specific part within the process assembly. The sub-assembly list is used to define the data entities that constitute the process assembly. The sub-assembly list is updated according to the process change request, and the updated sub-assembly list is synchronously updated in the corresponding process assembly nodes to ensure data consistency. This ensures that the target process bill of materials is a single, reliable source, preventing material mismatches, production stoppages, and quality defects caused by data inconsistencies, and guaranteeing the continuity and reliability of the manufacturing process.

[0047] In some specific embodiments, updating the sub-assembly list of the target process assembly includes: adding, deleting, or replacing at least one of the following operations on the part entries in the sub-assembly list.

[0048] For example, if the change involves adding a part to the assembly, a new part entry is inserted into the sub-assembly list's database record. If the change involves removing a part from the assembly, the corresponding part entry is logically deleted or disabled in the sub-assembly list. If the change involves replacing a part (such as upgrading part A from version 1.0 to 2.0), the part number and version information of the corresponding entry are updated in the sub-assembly list.

[0049] By adding, deleting, and modifying the parts in the sub-assembly list, precise online maintenance of process components is achieved, ensuring timely response to engineering changes. This ensures real-time synchronization between manufacturing instructions and design intent from the data source, avoiding material mismatch, quality defects, and production line stoppages caused by delayed or incorrect change information.

[0050] In some specific embodiments, the method further includes: performing creation, modification, or deletion operations on process assembly nodes in the target process bill of materials; and / or associating auxiliary materials or plates specified in a preset resource library with the corresponding material options in the target process bill of materials.

[0051] By performing creation, modification, and deletion operations on process assembly nodes, the target process bill of materials (BOM) can dynamically respond to manufacturing strategy optimizations. Process engineers can continuously optimize based on production practices, such as quality improvements, efficiency enhancements, or design changes. By precisely associating auxiliary materials and sheet metal from the pre-set resource library with the target process BOM, essential consumable resources that were not defined in the design phase but are necessary for manufacturing are included, bridging the gap between design data and manufacturing reality. This ensures the integrity and executability of manufacturing instructions, thereby eliminating production interruptions, quality fluctuations, and operational chaos caused by missing or unclear specifications of auxiliary materials at the data source.

[0052] In some specific embodiments, the method further includes: constructing an initial manufacturing bill of materials (BOM) based on the target process BOM and the vehicle code; generating a factory process document based on the target process BOM and manufacturing resource information, wherein the manufacturing resource information includes manufacturing equipment, tooling fixtures, and factory layout information; and updating the initial manufacturing BOM based on the workstation information in the factory process document to generate a complete manufacturing BOM for use in an enterprise resource planning system.

[0053] Plant process documents are used to characterize the set of work instructions that execute the assembly tasks in the target process bill of materials at specific workstations using specific manufacturing resources under a specific plant layout.

[0054] By combining the target process bill of materials (BOM) with the vehicle code, a general process solution is transformed into a unique initial manufacturing BOM required for a specific vehicle. Based on the assembly logic defined in the target process BOM and the physical constraints described by the manufacturing resource information, a process plant file is generated, thereby assigning abstract assembly tasks to specific workstations with corresponding capabilities. By associating and integrating the workstation information in the plant process file with the initial manufacturing BOM, precise binding between materials and geographical locations is achieved, generating a complete manufacturing BOM that drives efficient enterprise operations. This ensures a single, reliable source, thereby breaking down data barriers from process design to production execution, logistics, and cost accounting, and guaranteeing the efficient and reliable operation of the manufacturing system.

[0055] For some specific implementation methods, please refer to Figure 2 , Figure 2 This is a schematic diagram of a digital process provided in an embodiment of this application. For example... Figure 2 As shown, the implementation environment of this application involves multiple core systems, including a product development data management system (TC system), a process management system (IPS, Integrated Process System), an enterprise resource planning system (SAP, Systems, Applications, and Products in Data Processing), a manufacturing execution system (MES, Manufacturing Execution System), and an equipment operation parameter collection platform (IoT, Internet of Things). These systems interact and integrate data through a network.

[0056] In the aforementioned system environment, the data flow and processing from design to manufacturing includes: 1) Design Data Generation and Acquisition. Product configuration information and component master data are used by engineering bill of materials engineers in the TC system to generate the Engineering Bill of Materials (EBOM). This EBOM represents the product's design structure.

[0057] 2) Process Data Initialization and Integration. The IPS system pre-integrates component master data and product configuration information from the TC system. Subsequently, the IPS system receives the EBOM from the TC system and combines it with the integrated component master data to construct the initial process bill of materials (initial process BOM). This step ensures the inheritance and consistency of process data with the design source.

[0058] 3) Construction of the target process bill of materials. In the IPS system, the initial process BOM is combined with process configuration information (manufacturing-oriented instruction rules) converted from product configuration information. Based on this, process engineers use the maintenance functions provided by the IPS system to supplement the initial process BOM with the necessary auxiliary materials, sheet metal, and defined process assemblies, thereby generating the final target process bill of materials (target process BOM) used to guide process design.

[0059] 4) Parallel generation of manufacturing data. The target process BOM is combined with the specific vehicle identification number (VIN) and, through configuration rules, a precise list of materials required for the vehicle is selected to construct the initial manufacturing bill of materials (MBOM). The target process BOM is then combined with manufacturing resource information (including manufacturing equipment, tooling fixtures, and factory layout / hard point structures) to generate the factory process document (BOP), which specifies the workstation information for each assembly operation.

[0060] 5) Data Integration and Execution. The workstation information defined in the factory BOP is linked and integrated with the initial MBOM to form a complete MBOM. This complete MBOM contains comprehensive information on "what materials are used" and "at which workstation." The complete MBOM is then initially transmitted to the downstream SAP system to drive enterprise-level operational management such as production planning, material requirements, and cost accounting. Simultaneously, the factory BOP, factory structure, and process documents are transmitted to the MES system to guide production line operations, material distribution, and quality monitoring in the vehicle manufacturing plant. The IoT platform collects real-time operating parameters of manufacturing equipment and feeds them back to the MES and other systems, providing data support for production process monitoring and optimization.

[0061] By establishing a collaborative workflow centered on IPS, seamless data integration from engineering design to shop floor execution was achieved. By generating a complete MBOM containing both material and location information and synchronizing it as a single trusted source to the SAP and MES systems, issues such as data inconsistency and information silos were resolved, ultimately resulting in improved production efficiency, optimized logistics layout, ensured quality traceability, and controlled change risks.

[0062] In some specific implementations, the process for creating and maintaining process assemblies includes: 1) The system initiates the "Process Assembly Confirmation Process", and the task is assigned to the corresponding System Engineer (SE) or Manufacturing Engineer (ME).

[0063] 2) The SE or ME engineer applies for a unique process assembly number in the system using the "sub-assembly mode".

[0064] 3) In the initial process bill of materials, engineers can select multiple parts that need to be pre-assembled by dragging and dropping to create a sub-assembly list, which intuitively defines the composition of the process assembly.

[0065] 4) After the engineer completes the sub-assembly list, he / she saves and publishes it. The system then automatically triggers and completes the electronic signing and publishing process involved in the assembly flow of this process.

[0066] 5) Upon receiving the published sub-assembly list, the BOM engineer updates the overall target process bill of materials structure in the system and incorporates the process assembly into the target process bill of materials system that can guide production.

[0067] In some specific implementations, the process for managing process changes includes changes caused by design and changes initiated by the process.

[0068] For changes caused by design, the change process includes: 1) Process engineers participate in the approval process for design changes and make a preliminary assessment of the potential impact of the changes on the manufacturing process.

[0069] 2) After the design change is officially released, the process management system automatically receives the design change order and the new design data from the upstream system.

[0070] 3) Based on the changes, process engineers update the affected target process bill of materials and plant BOP.

[0071] 4) After the update is completed, the process personnel create a Process Change Notification (PWO) in the system and initiate the approval process for the process change caused by the design change to ensure that the process data and design data are updated synchronously.

[0072] For process-initiated changes, i.e., when problems are discovered within the process or improvement suggestions are made by the manufacturing department, the following process is initiated: 1) Process engineers directly modify the relevant plant BOP and target process bill of materials.

[0073] 2) After the modifications are completed, create a PWO and initiate a change approval process driven by the process department to achieve continuous optimization of the manufacturing process.

[0074] In some specific embodiments, the execution flow of process change notification is defined according to the project phase, including pre-production (SOP, Start of Production) flow and post-production flow.

[0075] The pre-SOP process includes: the certification engineer initiating the process change procedure; developing a detailed process change plan; the engineering and manufacturing process engineers simultaneously reviewing and approving the plan; developing or modifying equipment and tooling based on the approved plan; the certification engineer verifying the effectiveness of the process change; and finally confirming the verification results of the process change and completing the change.

[0076] The post-SOP process includes: the manufacturing process engineer initiating the process change process; developing a detailed process change plan; the engineering and technical personnel and the manufacturing process engineer jointly reviewing and approving the plan; developing or modifying equipment and tooling based on the approved plan; the manufacturing process engineer being responsible for verifying the implementation effect of the process change; and finally confirming the verification results of the process change and completing the change.

[0077] The specific changes to the process include, but are not limited to: adjustments to the target process assembly, updates to the factory BOP, auxiliary material usage, workstation information, and manufacturing resources.

[0078] Through the PWO (Product Change Provider) as a core platform, both design-driven and process-driven changes can be managed in a controlled process, from initiation, approval, verification to final implementation, ensuring that change information is accurately transmitted to downstream systems. This effectively controls risks and guarantees production continuity and product quality stability.

[0079] Accordingly, please refer to Figure 3 , Figure 3 A schematic diagram of a process assembly control system provided in this application embodiment is shown below. Figure 3 As shown, the system includes: an acquisition module for acquiring product configuration information, component master data, and an engineering bill of materials (OBM); a construction module for constructing an initial process bill of materials (BOM) based on the BOM and the component master data; a generation module for generating corresponding process configuration information based on the product configuration information; a determination module for determining at least one process assembly based on the initial BOM, the process assembly representing a combination of parts to be pre-assembled on a sub-assembly line; and an update module for updating the initial BOM based on the process configuration information and the at least one process assembly to generate a target BOM to guide manufacturing execution.
