And generating an SBOM initial structure based on the EBOM or manually constructing the SBOM initial structure. All constituent units of the SBOM can be called as LCN and are minimum units for guarantee analysis and management, and a guarantee design team of an enterprise usually carries out design and management around the LCN. After the SBOM structure is created, product basic attributes and supportability design related attributes are maintained for LCN, and the supportability design attributes are used. PartList needs to be maintained under each LCN, and all replaceable or possibly-required-to-be-replaced parts of the LCN are listed, including names, numbers, specifications and numbers of the parts. The PartList is usually obtained by initializing the lower-level structure of the product through the EBOM, and can also be input manually. In addition, information related to all after-sales services can be associated with the LCN, such as guarantee related design documents and maintenance equipment, and specific associated content is subjected to customized expansion according to the informatization degree and management requirements of an enterprise.

Description

Technical Field

[0001] The present invention belongs to the technical field of information management, and in particular relates to a product design data management method oriented to after-sales business. Background Art

[0002] In the mechanical and electronic manufacturing industries, products generally go through multiple stages, from demand analysis to overall design, subsystem design, finalization, production, after-sales, and scrapping. In order to manage product data, a product data management system is usually used to professionally manage product design data. Among them, BOM (Bill of Materials) is the core of product data management, which lists all components, parts, and raw materials required for a product or component. BOM usually includes information such as the name, quantity, code, and specifications of each component. In the process of product design and production, BOM is an important bridge for communication between design and manufacturing. BOM is usually divided into EBOM (engineering / design BOM), MBOM (manufacturing BOM), SBOM (Service BOM), etc. Among them, EBOM and MBOM have been fully polished in domestic software and widely used in domestic enterprises. However, SBOM has not been well designed and used in domestic software. Summary of the invention

[0032] The technical solution of the present invention is described in detail below in conjunction with the accompanying drawings.

[0033] The technical solution of the present invention is: Figure 1 As shown in the figure, the initial structure of SBOM is generated based on EBOM or manually constructed. All components of SBOM can be called LCN (Logistics Control Number), which is the smallest unit of support analysis and management. The enterprise's support design team usually designs and manages around LCN. After creating the SBOM structure, the basic attributes of the product and the related attributes of support design are maintained for LCN, and the support design attributes are used. Under each LCN, PartList (parts list) must also be maintained to list all replaceable or potentially replaceable parts of the LCN, including part name, number, specification and quantity. PartList is usually initialized from the lower-level structure of the product by EBOM, and can also be entered manually. In addition, all information related to after-sales business can be associated with LCN, such as support-related design documents, maintenance equipment, etc. The specific associated content is customized and expanded according to the enterprise's own informationization level and management requirements.

[0034] A method for managing product design data applicable to after-sales service, comprising:

[0035] The SBOM infrastructure is automatically generated based on the EBOM. The specific generation rules are customized according to the enterprise's supportability design requirements, and all the components (LCN) of the SBOM are the objects of supportability design.

[0036] The support designers adjust the SBOM structure according to the actual situation and add other key components as LCN.

[0037] Maintain LCN basic supportability design attribute information.

[0038] Maintenance planned maintenance tasks, planned maintenance tasks are usually used to guide the regular maintenance of products after sales. The specific task type is customized according to the company's business, such as the first overhaul task.

[0039] Related technical documents and supportable design documents can be divided into two categories: descriptive documents and reference documents. Descriptive documents are usually strongly associated with SBOM, and SBOM must be changed synchronously when the document is changed. Reference documents are weakly associated with SBOM, and SBOM can be changed as appropriate when the document is changed.

[0040] Maintenance and repair equipment. If the enterprise has implemented structured management, it is sufficient to associate the maintenance and repair equipment.

[0041] Customize the maintenance functions of other relevant information according to the characteristics of the enterprise to complete the maintenance of such information.

[0042] Specifically, Figure 2 As shown, SBOM initialization can be automatically generated by EBOM. The specific triggering time can be customized according to the business requirements of the enterprise, usually after the EBOM structure is basically complete and effective.

[0043] Specifically, SBOM can structuredly store information on design attributes, such as lifespan, renovation period, etc. It can also be expanded based on product characteristics and the company's design indicators for product assurance.

[0044] Specifically, the structure of SBOM can be adjusted. For enterprises with more product levels, some important underlying products may require a security design. In this case, the product can be added to the SBOM as an LCN.

[0045] Specifically, Figure 3 As shown, planned maintenance tasks can be used to guide the preventive and planned maintenance and overhaul of physical products, which helps companies provide good after-sales services and prevent performance degradation or product damage caused by untimely overhaul / maintenance of products.

[0046] Specifically, product support design documents can be linked to SBOM management, and changes to management documents and SBOM can be differentiated based on the strength of the association to avoid inconsistencies between data and design documents.

[0047] Specifically, SBOM has good scalability and can associate relevant security design information, such as repair and maintenance equipment, safety equipment, etc., according to the degree of informatization of the enterprise. Businesses that have not yet achieved informatization can also add new functions to SBOM to complete information entry, thereby facilitating the subsequent actual after-sales work.

[0048] Example

[0049] The first step is to automatically generate the SBOM infrastructure based on the EBOM. The specific generation rules are customized according to the enterprise's supportability design requirements, and all the components (LCN) of the SBOM are the objects of supportability design.

[0050] In the second step, the security designers adjust the SBOM structure according to the actual situation and add other key components as LCN.

[0051] The third step is to maintain the basic security design attribute information of LCN. And automatically generate the Partlist of LCN to show the product composition of LCN.

[0052] Step 4: Maintain planned maintenance tasks. Planned maintenance tasks are usually used to guide regular repair and maintenance of products after sales. The specific task types are customized according to the company's business, such as the first renovation task.

[0053] Step 5: Associate technical documents. Supportable design documents can be divided into two categories: descriptive documents and reference documents. Descriptive documents are usually strongly associated with SBOM, and when the document is changed, the SBOM must be changed synchronously. Reference documents are weakly associated with SBOM, and the SBOM can be changed as appropriate when the document is changed.

[0054] Step 6: Maintain the maintenance equipment. If the enterprise has implemented structured management, it is sufficient to associate the maintenance equipment.

[0055] Step 7. Customize the maintenance functions of other relevant information according to the characteristics of the enterprise and complete the maintenance of such information.

[0056] Implementation Cases:

[0057] In a certain R&D and manufacturing enterprise, the SBOM was constructed to achieve the management of the security design information of various products. The LCN structure, security attribute information, planned maintenance information, parts list information, maintenance equipment information, and design document information of the product were all maintained and managed. Based on the SBOM, a preventive maintenance warning dashboard for the product was generated to guide the renovation of the physical products that have been sold. At the same time, the maintenance demand of the product was put into production based on the parts list, and a production list was generated based on the predicted maintenance quantity of the product and the parts list to guide the production.
