An implementation method of a component type custom product structure tree

Abstract

The invention discloses an implementation method of a component type user-defined product structure tree, and relates to the technical field of data structures. The method is characterized by extracting the components of a product structure tree standardly and modularly, forming a static component and a dynamic component, and combining the static component and the dynamic component; forming the product structure tree template, adopting three customization methods of the customization of a basic component layer, the customization of a product structure template level and the dynamic customization during operation to customize the content of the product structure template in a custom manner; and forming the product structure tree instances, so that the customization capability of the product structure tree is improved; the construction of a personalized product structure and the organization and management of data can be carried out according to requirements; the flexibility of organizing and managing data by using the product structure tree and the capability of interpreting the data across the product structure tree are improved, the definition and implementation flexibility of the structure tree are improved, the correctness and consistency of organizing the data in a product structure tree mode are ensured, and the requirements of various industrial applications can be met.

Description

technical field [0001] The invention relates to the technical field of data structures, in particular to a method for realizing a component-style self-defined product structure tree. Background technique [0002] At present, the product structure tree is the most commonly used data organization method in industrial software, and is generally used in the application systems of industrial enterprises. Systems such as PDM, ERP, and CAPP organize and manage engineering data around the product structure tree. Although this data organization form is common, there are four outstanding problems in the application: First, the realization mechanism of the product structure tree is common Poor performance and insufficient reusability of the implementation method; second, the ability to customize the product structure tree is poor, and it is very difficult to customize when it is necessary to expand the node types, attributes, and relationships of the product structure tree during use; ...

Problems solved by technology

Systems such as PDM, ERP, and CAPP organize and manage engineering data around the product structure tree. Although this data organization form is common, there are four outstanding problems in the application: First, the realization mechanism of the product structure tree is common Poor performance and insufficient reusability of the implementation method; second, the ability to customize the product structure tree is poor, and it is very difficult to customize when it is necessary to expand the node types, attributes, and relationships of the product structure tree during use; the third is The current product tree implementation technology cannot meet the needs of multiple users for simultaneous use because it cannot provide personalized configuration capabilities; fourth, it is difficult to share data between different product structure trees, and the data reusability across structure trees is poor

[0005] (1) The reusability of the product structure is limited. Due to the insufficient analysis and dissection of the product structure tree, the product structure tree is not decomposed into more reusable components, which leads to the difficulty of reuse at the level of the product structure tree. large and infeasible;

[0006] (2) The ability to customize the product structure in the application is weak. Although some products provide customization of attributes, the customization ability in relation, version, etc. is weak or missing, which cannot meet the requirements of personalized applications and limits the flexibility of applications. ;

[0007] (3) Insufficient ability to interpret product data across product structures, because each product structure tree is interpreted independently and has no common logical constraints, which leads to difficulties in interpreting cross-structure data of product structures and causing difficulties in data integration
