面向系统概念设计的OPM到CPN转换方法

A Transformation Method of OPM to CPN for System Conceptual Design

对象过程方法论(OPM)是一种图形化建模语言,适合用于系统工程中概念设计阶段的概念模型开发,但其缺乏定量计算的能力。针对这一不足,提出并实现了一种将OPM转换为一种支持仿真和分析的可执行建模语言——着色Petri网的方法,结合OPM概念描述能力及CPN仿真分析能力,使系统工程过程更为连续。该转换规则实现了基本建模元素的转换以及层次性的转换,并通过反潜作战系统的案例研究对该转换方法进行了验证。

Object Process Methodology（ OPM） is a graphic modeling language appropriated for conceptual design in Systems Engineering; however,it lacks computational capability. In this paper,we introduce and implement a method transforming OPM to Coloured Petri Net（ CPN）,an executable modeling language supporting simulation and analysis. This method combines the describing ability of OPM and the simulation and analysis ability of CPN,and makes the process of Systems Engineering more continuous. According to the proposed transformation rules,the method converts not only the basic building blocks but also the hierarchical properties from OPM models to CPN models. A case study on an anti-submarine system demonstrates the transforming process and the validity of this method.
