虚拟企业业务流程的建模方法研究

为设计分析虚拟企业生产运作系统, 针对虚拟企业业务流程的特点, 应用UML、Petri网和面向对象技术, 提出了虚拟企业业务流程的建模方法. 该方法分全局业务流程和子业务流程两个层面, 全局业务流程采用UML序列图和Petri网建模, 表示虚拟企业各成员之间的交互接口关系; 子业务流程采用面向对象的Petri网建模, 实现成员企业内部流程的表达、封装和相互之间的业务连接. 仿真验证表明, 所建模型满足合理性要求.

A modeling method for virtual enterprise business process

In this paper, a modeling method for virtual enterprises business process is proposed by use of Unified Modeling Language (UML), Petri Net and Oriented Object (O-O) technology in order to design and analyze the production operation system of virtual enterprise. The general model consists of sub-models including the model of total business process and some other models of sub-business process based on the characteristic analysis of virtual enterprise business process. The model of total business process is derived from expressing alternating and interface relation among the member enterprises, and it is set up by UML sequence diagram and Petri net. The model of sub-business process is expressed by the Petri Net model of object oriented technology, wiith which the internal process in the member enterprises are packaged, and the businesses in between are connected. The simulation results show that the developed models meet the technical requirements with practicality and feasibility.
