摘要:

将设计结构矩阵与着色Petri网结合后,进行了产品设计过程建模与仿真的研究。首先利用设计结构矩阵对产品设计过程进行建模,从产品设计过程特点出发,为支持基本过程逻辑的描述定义了着色Petri网基本网模型结构,将设计结构矩阵映射为着色Petri网,建立了产品设计过程着色Petri网模型。在此基础上建立了对设计资源进行有效分配的动态分配模型,通过定量仿真分析,实现了产品开发过程资源冲突的检测及资源的重新分配和调整。桥式起重机小车设计的实例说明了该方法的有效性。

Abstract:

Combined the DSM(design structure matrix) and the colored Petri nets,this paper presented a research of product design process modeling and simulation. First, the product design process was modeled based on the DSM, and to support the description of the basic logic process, the basic nets model structure of the colored Petri nets was defined from the view of product design process characteristics. Through the mapping from the DSM to the colored Petri nets, a colored Petri nets model of product design process was established. On the basis of that, the dynamic distribution model of the effective design resources distribution was established. Through quantitative simulation analysis, the collision detection, reallocation and adjustment of the resource were realized in the product development process.As an example,a bridge crane car design was used to show the effectiveness of the method.

Key words: design structure matrix, product design process, modeling and simulation;colored Petri net
