基于模型构件和Petri网的企业整体建模方法

Holistic Modeling Methodology of Enterprise Based on Components Model and Petri Nets

模型复用是提高建模质量和效率的主要手段,而模型构件是复用的核心和基础。在对构成企业这一社会技术系统的各种要素进行分析的基础上,首先将组成系统的要素分为功能构件、资源构件和人力构件等三类模型构件。然后以Petri网作为建模工具,给出一种以模型构件作为变迁和库所的企业整体建模方法。由此方法建立的企业模型具有良好的整体性和可复用性,能够全面反映构成企业的技术实体、资源和人等要素的配置和相互关系。最后给出一个企业建模实例。

Model reuse is regarded as a main means for improving the quality and efficiency of modeling. And model Component technology is regarded as the core and foundation of model reuse. After all elements that make up an enterprise have been analyzed, those are grouped into three kinds of model components： function component, resource component, and human component. And then, a methodology of holistic modeling is introduced, using Petri net as modeling tool, function components as transitions, resource components and human components as places. The model constructed by this methodology is holistic and reusable, and it can reflect all aspects of the modeled enterprise as a whole. Finally, a modeling example is given.
