摘　　要：为了准确描述复杂产品协同工作过程,提出了一种基于模糊时间Petri网(FTPN)的工作流建模和性能分析方法。首先,给出了协同开发任务链接关系的形式化定义,将工作流模型的关键路径计算转化为一个基于FTPN状态方程的求解问题。并在此基础上,结合实例计算了某工程项目在约束条件下完成的可能性。结果表明,该方法可以方便确定产品协同开发过程中的关键环节,为产品协同工作的组织和管理提供指导。In order to make an accurate description for complex product collaborative work process, a method for modeling of workflow and performance evaluation based on fuzzy-timing Petri Nets was proposed, Firstly, the formal definition of link relation among collaborative tasks was given, and the computation of critical path was transformed into a problem of finding the solutions by solving state equation based on FTPN. Furthermore, the completion possibility of an engineering project was calculated in the time restriction. The conclusion is drawn that this proposed method is convenient to determine the critical juncture of product collaborative development process, and can also provide guidance for organization and management of product collaborative works.
