PLM系统中的设计变更管理实现

Realization of Engineering Change in PLM System

指出了设计变更的主要原因包括功能缺陷、设计错误、结构改进、用户需求改变、产品质量问题、产品开发的条件改变等 ,分析了设计变更中变更流程、变更执行和文档管理等要素的特点及其相互联系 ,论述了设计变更管理与PLM(ProductLifeCycleManagement)系统的关系 ,认为PLM系统是实施设计变更管理的基础 ,设计变更过程是一个具有生命周期的过程。阐述了设计变更管理的详细过程 ,指出设计变更管理的主要目的是降低变更成本、提高变更效率和减少变更错误 ,提出了以PLM系统为基础 。

It is pointed that the main reasons of engineering change including the shortcoming of the product,the wrong design,the improvement of the product structure,the change of the customers' requirement,the quality of the product,the condition change of the product,etc.. All the factors and their relations related to engineering change management are analyzed. Such factors as the changing process and the product lifecycle management are discussed in detail. After analyzing the relation between engineering change management and product lifecycle management, the object of engineering change management and its difference is put forward. The basic aim of engineering change management is to develop change ratio of products with lower cost and less error. It is argued that effective product lifecycle management is fundamental to engineering change management. A model of implementation of engineering change management is provided according to the previous analysis.
