Product information modeling method in collaborative environment based on product entire life cycle

Abstract

A product information modeling method in a collaborative environment based on a product entire life cycle comprises the following four steps of: 1, establishing a generalized model basic framework according to a WBS (Work Breakdown Structure); 2, when the BOM (Bill Of Material) is updated, extracting the BOM information of each view; 3, finding a slave information model related to the updating in a unified product information model, if the slave information model is found, updating and upgrading the slave information model, comprising inserting or deleting a new node, and changing the relationship between nodes, and if the slave information model is not found, finding the node on the higher level to which the slave information model belongs, then creating a view and a relationship, and establishing the UPIM (Unified Product Information Model); and 4, continuously judging whether the BOM is updated, and repeating the steps. The product information modeling method in the collaborative environment based on the product entire life cycle has a better practical value in the technical field of computer aided design.

Description

technical field [0001] The invention relates to a product information modeling method in a collaborative environment based on a product full life cycle, and also relates to an XBOM (a general name for various bills of materials) of a product full life cycle, belonging to the technical field of computer-aided design. Background technique [0002] With the development of information construction of domestic small and medium-sized enterprises, the demand for network-based remote and multi-disciplinary collaborative simulation is also increasing. Through the collaborative simulation process information modeling and data maintenance in the network environment, enterprises can establish a common understanding of product data and collaborative product simulation work mode, organize multiple development teams to carry out collaborative development, give full play to the potential of professional workers or complement each other, correct The development cycle is too long and the deve...

On the other hand, the existing simulation process information modeling and maintenance methods do not pay attention to the integration with PDM information, cannot guarantee the integration of PDM information, and cannot guarantee that the information entering the simulation analysis process information and simulation database from the PDM system is traceable. Consistent, continuous, and information modeling of the simulation process based on the product structure tree can effectively solve this problem
