Product multiple-BOM (bill of material) tree configurator based on unified material store

Abstract

The invention discloses a product multiple-BOM (bill of material) tree configurator based on a unified material store. The product multiple-BOM tree configurator is provided with a computer system in which a material management system is installed. The product multiple-BOM tree configurator is characterized in that the material management system is internally provided with a material store and a product store, wherein the material store is provided with a basic material property sheet and a material relationship sheet; the product store is provided with a base type product BOM tree, a base type product first-layer material relationship sheet, a product multiple-BOM tree configurator, a client product multiple-BOM tree and a client product first-layer material relationship sheet. The realization method of the product multiple-BOM tree configurator comprises a configuring method and a use method. The invention has the obvious effects that the logic relationship of administrative subordination between parts in the product of each stage in different life cycles can be intuitively showed, the computerized management of products can be carried out conveniently, information consistency maintenance difficulty and workload of parts between different BOM tree structures is reduced and the efficiency of the data of each BOM tree structure is ensured. The product multiple-BOM tree configurator can be independently used, and can be embedded into CAD (computer-aided design) / CAPP (computer-aided process planning) / PDM (pulse duration modulation) / ERP (enterprise resource planning) systems for use.

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, packing and transportation, after-sales service, disassembly and recycling, and specifically relates to a product multi-BOM tree configuration based on a unified material library device. 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 o...

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
