基于设计结构矩阵的机械仿真流程组建及评估

Creation and Evaluation of Mechanical Simulation Process Based on Design Structure Matrix

为了提高机械仿真流程的执行效率,将设计结构矩阵(DSM)引进机械仿真流程的创建中。根据机械仿真流程的特点,归纳出五种基本逻辑单元,给出相应的DSM基本逻辑单元。利用DSM对机械仿真活动之间信息传递关系进行分析,得到初始DSM,并进行重构。通过分析重构后的DSM,对照DSM基本逻辑单元,组建并得出以流程图形式表示的机械仿真流程。同时,提出信息等待时间的概念,给出目标优化函数,以其作为评价标准,对重构后的DSM进行评估。最后通过一个仿真实例验证该方法的可行性,并对方法中的优化模型做出相应的简化。

To improve efficiency of mechanical simulation process execution, the theory of design structure matrix （DSM） was introduced into the problem of creating mechanical simulation process. Depending on the characteristic of mechanical simulation process, 5 types of based logistic cell was concluded. And each has a denotation by a based cell of DSM. The relationship of information among mechanical simulation activities was analyzed by DSM. Then the original DSM was partitioned. According to analyzing the DSM partitioned, a mechanical simulation process showed by.flow chart was created based on based cells of DSM. As the same time, the concept of process information waiting time was proposed. It was used of the metewand for evaluating oSthe DSMpartitioned. Finally, the method was verified by an engineering simulation example. And the optimization model was made some simplified.
