Method for configuring product multi-BOM tree based on base products

Abstract

The invention relates to a method for configuring a product multi-BOM tree based on base products, which is characterized by comprising the following steps of: establishment of a unified material library, a base product library and a product multi-BOM tree configurator; and selection of a base product design BOM and configuration of the product multi-BOM tree, which comprises the following processes of: decomposing client product feature attributes downwards; searching substituted and newly added materials; configuring first-layer materials of the product design BOM tree; finely adjusting the materials in the product BOM tree; and configuring the client product multi-BOM tree. The method has the obvious advantages of intuitively configuring the logic subordinate relationships among parts in the product at different stages of the life cycle, contributing to product information management, reducing the difficulty and workload of maintaining the consistency of information of the parts among different BOM tree structures and ensuring the effectiveness of data of each BOM tree structure of the product. The product multi-BOM tree configurator can be independently used and also can be embedded into a CAD / CAPP / PDM / ERP system.

Description

technical field [0001] The invention belongs to the technical field of management of products and materials in various stages of the product life cycle such as design, process, manufacturing, transportation, after-sales service, disassembly and recovery, and specifically relates to a multi-BOM tree configuration method for products based on basic products. Background technique [0002] In a manufacturing enterprise, products are composed of components with a hierarchical structure. Generally speaking, products are composed of components at the next level, components are composed of small components at the next level, and small components are composed of parts at the next level, etc., different The hierarchical structure of complex products is different. The more complex the product, the more layers of components it has. For example, the components of automobile products can generally be divided into 7 layers, while the components of simple products may only have 2-3 layers. ...

AI Technical Summary

Problems solved by technology

[0009] However, the disadvantages of the traditional technology for expressing multiple BOM trees of a product are: 1. The parts that make up the product are represented by a one-dimensional schedule. There is no hierarchical structure and it is not intuitive. It is impossible to understand the logical affiliation relationship between the parts inside the product at a glance, which is inconvenient for product information. 2. Product design BOM, process BOM, manufacturing BOM, packing BOM, after-sales service BOM, dismantling and recycling BOM are compiled and maintained by the design department, process department, manufacturing department, sales department, and after-sales maintenance department respectively, independent of each other It requires manual input and repeated writing for many times, and the workload is heavy and error-prone; 3. The parts and materials in each stage of the product life cycle cannot be associated. When the product design BOM changes, it is difficult to quickly find the process BOM, manufacturing BOM, assembly The change of the corresponding parts in the box BOM, after-sales service BOM, and dismantling and recycling BOM causes inconsistencies in the BOM structure, component configuration and version in the product BOM multi-view, making the product design status inconsistent with the final delivered product status, resulting in customer rejection. 4. Product design, process, manufacturing, after-sales service and disassembly and recycling do not use a unified material library. The same material has inconsistent descriptions of codes, names, attributes, etc. at different stages of the product life cycle, resulting in confusion in product design and production organization. The design and manufacturing cycle is long, the cost is high, and the quality cannot be effectively guaranteed
