基于IDEF和UML的虚拟装配系统建模

为了解决复杂虚拟装配系统的系统建模问题,在分析IDEF和UML建模方法优缺点的基础之上,提出了一种两者相结合的系统建模方法.首先利用IDEF建立系统的功能模型、信息模型和过程模型,再根据IDEF和UML模型之间的映射机制,将IDEF模型转换为UML模型,从而完成系统从需求分析、功能设计、对象设计直至软件实现的整个过程.该方法能有效弥补单纯采用IDEF方法建模或UML方法建模的缺陷,实践证明在虚拟装配系统建模中具有重要的应用价值.

Virtual assembly system modeling based on IDEF and UML

In order to solve the system modeling problem of a complex virtual assembly system,on the basis of analyzing the advantages and shortcomings of IDEF method and UML method,a hybrid approach combining IDEF with UML is proposed.Firstly the IDEF0 function model,IDEF1X information and IDEF3 process model were erected;according to the mapping mechanism between UML and IDEF,these IDEF models were transformed into UML models;and the modeling process of the system was completed according to the requirement analysis,function design,object design and software development.This method can effectively avoid the deficiencies of pure IDEF method or UML method,and has been demonstrated to have a good application value in modeling the virtual assembly system.
