Description

Technical Field

[0001] This invention mainly relates to the field of intelligent management technology in manufacturing, specifically a method, system, and storage medium for automatically constructing SBOM based on MBOM. Background Technology

[0002] Among product data, the most important is the Bill of Materials (BOM). For product manufacturing companies, the BOM is the link connecting raw materials (purchased components) to the final product. In terms of enterprise information systems, the BOM is the most important foundational data in PDM / PLM / ERP / MRO and other information systems, and it is also the most complex. The BOM is an important basis for the finance department to calculate costs and for the operation of R&D, design, manufacturing, and maintenance services.

[0003] Manufacturing enterprises typically use PDM / PLM and ERP systems to manage the design of Bill of Materials (EBOM) and Manufacturing Bill of Materials (MBOM). The conversion and management of EBOM to MBOM is a primary issue that enterprises must address in their information management. There is considerable research and practical experience in this area. However, many enterprises lack expertise in building SBOMs for operation and maintenance services, and mainstream PDM / PLM or ERP systems have failed to adequately address this challenge.

[0004] The exploration and application of this unexplored area is largely led by enterprises, especially those manufacturing complex products. Because complex products (such as aircraft, ships, and high-speed trains) have service lives of 20-50 years and require highly specialized maintenance and repair, manufacturers must be deeply involved in product maintenance and support, and must implement full product lifecycle management. SBOM (Structured Business Object Model) construction and configuration management oriented towards the service lifecycle is an indispensable part of this process. Due to the high complexity of these products, enterprises should build SBOMs based on existing design and manufacturing data to maintain consistency of product data across all stages of the lifecycle. This is the primary choice for complex product manufacturers and a concrete manifestation of full product lifecycle management.

[0005] Current research on SBOM construction based on existing data still largely follows data processing methods from the design and manufacturing stages, failing to meet the requirements of data transformation and integration in practice. The main challenges in building SBOMs based on existing data include the following:

[0006] (1) It is difficult to standardize and generalize the construction of SBOM. Differences in the business format, management model and information system of different enterprises, as well as the content and conversion process of EBOM and MBOM, will affect the conversion and construction of SBOM.

[0007] (2) When enterprises develop information systems such as PDM and ERP, they do not pay enough attention to the identification of SBOM construction needs. When it is necessary to build SBOM and perform configuration management (usually when enterprises build professional operation and maintenance service systems, such as MRO), there is a gap in this aspect. It is necessary to study the supplementary technical solutions of EBOM and MBOM to support SBOM generation.

[0008] (3) The SBOM should meet various needs of product after-sales service and maintenance support, such as: realizing the connection of configuration data and maintenance data throughout the service life based on the BOM, supporting hardware configuration and software configuration management, supporting the generation of configuration baselines required for various business executions, and supporting the construction of illustrated parts catalogs and interactive electronic technical manuals. Therefore, the data of the SBOM should be highly consistent and from the same source as the enterprise's EBOM, MBOM and master data (MDM) systems, be able to transmit information such as BOM version and internal changes, and have a reasonable triggering, conversion and generation mechanism for SBOM construction.

[0009] To address the challenges of SBOM (Simplified Business Model) construction, complex product manufacturers need to utilize digital and information technology to resolve the technical difficulties related to BOM (Bill of Materials) management from the perspective of product lifecycle management. This can be achieved by optimizing EBOM (External Business Model) and MBOM (Material Business Model) compilation rules, improving relevant information systems, and integrating SBOM construction with the development of operation and maintenance service systems. This will meet the needs for data integration throughout the product service lifecycle and the management of configuration and maintenance data, achieving the following objectives:

[0010] (a) Ensure the relevance, accuracy and consistency of the SBOM with the EBOM and MBOM.

[0011] (b) Ensure that the SBOM required for each stage of the product service life can be generated automatically, accurately and in a timely manner.

[0012] Existing Bills of Materials (BOMs) are typically designed based on product structured data models, and there are two main approaches to existing maintenance data structure models:

[0013] (a) Full lifecycle data model: Using the product full lifecycle data model to manage data at each stage, including data in the maintenance stage, is also a research focus in the field of product full lifecycle management.

[0014] (b) Build a separate SBOM: Design a product data management model that is only applicable to maintenance, based on the needs of the maintenance phase.

[0015] The table below shows a comparison of the classifications of maintenance data structure models.

[0016] Comparison Table of Maintenance Data Structure Model Research by Category

[0017]

[0018] Some practitioners have also proposed research results, such as a data conversion method and system from EBOM to SBOM (Chinese Patent Application No. CN202010790348.0), a service BOM construction method and system (Chinese Patent Application No. CN202110814822.3), and a subway vehicle maintenance BOM generation method based on EBOM (Chinese Patent Application No. CN202010145672.7), etc. However, existing technologies still have some technical problems that urgently need to be solved:

[0019] 1. Lack of an automated SBOM generation environment: In the application of the full lifecycle data model, the focus is usually on the system planning and management of EBOM and MBOM. Building SBOM based on existing design and manufacturing data to maintain the consistency of product data at each stage of the lifecycle is the main choice for complex product manufacturing companies. However, due to the lack of information system-based methods for the association and conversion of SBOM with EBOM and MBOM, as well as the lack of a data environment, it is difficult to automatically build SBOM in batches.

[0020] 2. Lack of methods and systems for automatically generating SBOM based on MBOM: Existing SBOM construction methods either build the SBOM separately or build a neutral BOM (Super BOM, XBOM, etc.) and then generate the SBOM through traversal and other methods. This has problems such as a large workload for manual creation, insufficient professionalism of the creators, or errors in the work, which may result in incomplete or inaccurate SBOM construction. Treating the conversion of SBOM as an independent object can easily lead to inconsistencies with the front-end data of design and manufacturing, and the SBOM structure differs greatly from the instance structure. Summary of the Invention

[0074] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0075] For ease of understanding, the basic terms involved in this invention are described in detail below, as shown in the table below:

[0076]

[0077] This invention belongs to the technical fields of product lifecycle management, maintenance data structure model, configuration management, and BOM management in the complex product manufacturing industry. It is used for the definition and construction of SBOM in the service life stage of complex products.

[0078] like Figure 1 As shown, the method for automatically constructing SBOM based on MBOM according to the present invention includes the following steps:

[0079] Step S1: Build an automatic SBOM generation environment;

[0080] Building an automated SBOM generation environment is a crucial step in creating a product SBOM. Building an SBOM based on a full lifecycle data model requires preparing the data environment according to the evolutionary path from EBOM to MBOM to SBOM.

[0081] Step S2: Automatically generate the product SBOM based on the MBOM.

[0082] In a specific application example, the detailed process of step S1 may include:

[0083] Step S101: Based on the characteristics of SBOM application in operation and maintenance services, add identifiers to the attributes of materials and components and establish rules to support automatic generation of identifiers; such as LRU / SRU, spare parts / spare components, maintenance level, etc.

[0084] Step S102: Add identifiers to EBOM and MBOM, such as LRU / SRU, spare parts / spare components, maintenance level, etc.

[0085] Step S103: Based on the identifier (such as LRU / SRU identifier), establish the rule that the tag number of EBOM and MBOM must be filled.

[0086] Step S104: Establish rules to standardize the separator characters for the "breakpoint" and "continuous" categories in the BOM.

[0087] Step S105: Based on the “tag number” and “quantity” information of EBOM and MBOM, verify the number of tag numbers to ensure that the number of tag numbers is consistent with the “quantity” of the material.

[0088] Step S106: Create a line-splitting mechanism for merging nodes in the MBOM structure, such as... Figure 2 As shown.

[0089] See Figure 3In specific application examples, depending on the business application scenario of the operation and maintenance service, the detailed process of step S2 may include:

[0090] Step S201: Obtain MBOM;

[0091] Step S202: Create rules for automatic generation of the product SBOM;

[0092] Step S203: Create the product SBOM model.

[0093] In practical applications, step S201 involves selecting the MBOM (Model-Based Object) that most closely resembles the hardware structure of the finished product instance as the data source for SBOM generation. The specific process includes:

[0094] Step S2011: Based on the product material code (also known as product drawing number, etc.) and MBOM version information in the finished product factory configuration, obtain the MBOM structure information for that version.

[0095] Step S2012: Create MBOM retrieval rules to prevent the same version of MBOM information from being retrieved repeatedly.

[0096] Based on business application scenarios for operation and maintenance services, SBOM can be divided into service SBOM and maintenance SBOM. Maintenance SBOM can be further divided into various levels of maintenance SBOM based on maintenance severity. For specific applications, see [link to relevant documentation]. Figure 4 In step S202, the specific process for creating automatic SBOM generation rules includes:

[0097] Step S2021: Based on the product factory attributes and material master data attributes, as well as the list of essential replacement parts and the product (or model) maintenance plan, create a service SBOM and a repair SBOM;

[0098] Step S2022: Generate an identifier for the service SBOM based on the LRU and service spare parts identification attributes;

[0099] Step S2023: Generate identifiers for maintenance SBOM based on LRU, SRU, service spare parts identification attributes and product maintenance plan;

[0100] Step S2024: For special projects, an additional list of required replacement parts can be embedded as an extended identifier for the maintenance SBOM generation;

[0101] Step S2025: Create an SBOM structure tree based on the material serial number traceability identifier;

[0102] Step S2026: Based on the product maintenance plan, create the corresponding level of maintenance SBOM;

[0103] Step S2027: Construct the SBOM structure tree based on the material serial number traceability identifier.

[0104] In a specific application example, in step S203, the product SBOM structure model mainly includes two parts: a structure tree and a child list.

[0105] The structure tree nodes are mainly composed of three types of nodes: top-level, middle-level, and bottom-level (corresponding to the root, branches, and leaves). Based on fields such as "product code," "product description," "tag number," and "tag number description," structure tree node title rules are established, such as tag number + tag number description. Using first-level systems or products as configuration items, upstream and downstream nodes and manufacturer correspondences are created to meet the requirements for cross-vendor joint construction of the SBOM (Structured Module Name).

[0106] This includes obtaining material loading rule information based on tag numbers. The child list displays the basic attributes of the product at the node location, as well as the list of traceable parts, non-traceable parts, and software information of its direct subordinates.

[0107] As a preferred approach, the product SBOM can be built hierarchically, categorized into system / component SBOM and model SBOM. Using the system / component SBOM as the data source for model SBOM generation, the rules for creating model SBOMs are as follows:

[0108] (a) Create the model SBOM structure based on the model supply list.

[0109] (b) Based on the tag information in the BOM structure, create an automatic location number generation mechanism to identify the location of components or devices installed or arranged in the model, which facilitates product quality data analysis and material traceability.

[0110] (c) Create a position number organization character specification, which can distinguish the membership relationship of components by characters.

[0111] (d) Organize characters based on position numbers to create components and quickly and accurately locate component positions.

[0112] See Figure 5 This is a schematic diagram generated using the SBOM of a high-speed train model in a specific application example.

[0113] like Figure 6 As shown, the present invention further provides a system for automatically constructing SBOM based on MBOM, which includes:

[0114] Material Attribute Management Module: Connects to the material development system and EBOM / MBOM management modules, receives / inherits the initial attribute values ​​of materials defined by the material development system, collects and manages material (basic or general) attributes, transmits material master data (basic or general) attributes to EBOM / MBOM, and receives the best suggested attribute values ​​pushed back by the EBOM / MBOM management modules.

[0115] EBOM / MBOM Management Module: Connects to the Material Attribute Management Module to receive / inherit material master data (basic or general) attributes, and to establish and maintain system / component plant attributes; connects to the SBOM Management Module to transmit the system / component BOM structure and corresponding material plant attributes.

[0116] SBOM Management Module: Connects to the EBOM / MBOM Management Module to receive / inherit the system / component BOM structure and corresponding material plant attributes, generate system / component SBOM and model SBOM, and collect and manage SBOMs; connects to the Material Replacement Management Module to construct corresponding installation rules based on the initial material code corresponding to the tag number in the BOM structure (specifying the parts that can be installed at the location of the configuration item and managing them through replacement relationships).

[0117] Material Replacement Management Module: Based on material codes, it classifies materials into bidirectional, unidirectional, and conditional categories, establishes material loading rules, and connects with the SBOM management module to proactively push material loading rules to the SBOM. Basic material loading rule information (material replacement groups) can be created in the EBOM by tag number and transferred to the MBOM-SBOM.

[0118] See Figure 7 This is a schematic diagram of a product SBOM built using the above system in a specific application example.

[0119] The system described above in this invention can be applied to multiple fields (design and development, production and manufacturing, operation and maintenance services, etc.) of complex product manufacturing enterprises according to actual needs, and involves multiple information systems: business process management system, master data system, product development system (product lifecycle management system), enterprise resource planning system, manufacturing execution system, operation and maintenance service system, etc.; and multiple systems jointly support the construction of SBOM and form data connectivity. Material attribute management module enables the addition and definition of material attributes, which are applied to front-end information systems such as EBOM / MBOM management module, optimizing EBOM and MBOM compilation rules, improving from the source, and combined with material replacement management module to optimize material replacement rules, supporting SBOM management module to realize SBOM conversion and generation.
