Embodiment Construction

[0064] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0065] Such as Figure 5 The product structure diagram of a certain product is shown, but due to the needs of distributed design and manufacturing, the BOM data structure of component 1 and component 2 may be different. For example, component 1 adopts the data structure of the mesh model, while component 2 adopts the matrix formula structure. During information integration, upstream design and manufacturing personnel need to understand the tolerance characteristics of part A in component 1, and the specific steps can be (such as figure 2 shown):

[0066] Step 1: Information integration of heterogeneous BOM. The integrated BOM table can be expressed as shown in Table 3 below:

[0067] Table 3 BOM summary table after integration

[0068] product number

Abstract

The invention relates to a method for customizing and inquiring a heterogeneous BOM (Bill of Materiel) based on a complex product. The method is realized on the basis of a hierarchical structure model of a browser/server and comprises the following steps of: 1) collecting information of the heterogeneous BOM: realizing data sharing and interactive updating of various heterogeneous BOM data structures by a uniform data interface; 2) establishing a BOM attribute data table of a data layer and executing an automatic extracting system: dividing the BOM attribute data table into a main attribute information general table and a configuration attribute information general table, and performing an automatic extracting program, namely extracting the BOM attribute data, and then updating the BOM attribute data by adopting an updating strategy program if the BOM table is changed; and 3) designing a user operation method for manufacturing personnel. The method has the beneficial effects that: (1)the design and the technology are convenient, and the manufacturing personnel can conveniently inquire and acquire the appointed BOM information; (2) the operation can be simplified or performed in aparallel manner in a manufacturing process, the comparison is realized and the manufacturing efficiency is promoted; and (3) the instantaneity and the accuracy of data are ensured.

Description

technical field [0001] The invention relates to a custom query method based on complex product heterogeneous BOM, which belongs to the field of product data management (PDM) in industrial engineering. Background technique [0002] BOM (Bill of Material) is a product structure data file that can be recognized by a computer, and is the data format of a product structure. BOM is usually a tree-like data structure, which reflects the parent-child relationship of components and supports any level of query, expansion and summary. BOM is the basis of product information and one of the most important information in manufacturing enterprises. The two most prominent forms of BOM information in large manufacturing enterprises are engineering BOM (Engineering Bill of Material, EMOB) and manufacturing BOM (Manufacturing Bill of Material, MBOM). [0003] The EBOM information of a manufacturing enterprise is a technical document describing the product structure. It defines the structural ...
