Abstract: Based on analyzing the flexible software theory, this paper carries on the discussion of the software flexible system structure, unifies in the software development the experience, and constructs the product life cycle management system based on the work flow technique. With the aid of the object-oriented dynamic modeling mechanism, UML activity chart and the state diagram, it takes the system flow realization in product order form processing work as the example, carries on the simulated description and the analysis to the system.

Key words: Product lifecycle management (PLM), Flexible software, Workflow, Unified modeling language (UML)

摘要： 在分析柔性软件理论的基础上，对软件的柔性体系结构进行了探讨，结合软件开发中的体会，构建了基于工作流技术的产品生命周期管理系统，借助面向对象的动态建模机制――UML活动图与状态图，以系统流程实现中的产品订单处理工作流为例，对系统进行模型化描述与分析。
