一种虚拟企业业务过程集成化建模方法研究

敏捷虚拟企业（即动态联盟）是21世纪组织管理形式，在CIMS工程实施中,对虚拟企业的建模和优化工作的研究越来越显现出其重要的地位和紧迫性。作者提出了一个适用网络化虚拟企业业务过程动态优化的一体化建模方法IEPU，该方法集IDEF0、扩展事件过程驱动链（EEPCs）、扩展Petri网（EPN）和标准化面向对象的建模语言（UML）为一体，其在层次上是从上到下逐渐细化过程。符合从功能分析、详细设计到具体实施的生命周期。使用该方案可以弥补单一方法的不足，优势互补，最适合复杂企业特别是虚拟企业的建模、分析和优化。并着重对建模过程中EEPCs到EPN之间的转换进行了讨论。

Integrated Methodology in the Process Modeling of Virtual Enterprise

The importance of modeling and optimization of agile virtual enterprises is widely recognized by CIMS researchers. These integrated modeling methods named IEPU are discussed, which can be used for agile virtual enterprises process dynamic optimization. These methods are integrated by the methodologies of IDEF0, extended event process chains (EEPCs), extended Petri net and unified modeling language (UML). The combination of these methods means that the weaknesses of each can be counteracted by the strengths of others. These combined methods have been used to model the virtual enterprise required through different stages from function analysis and designing to implementation. These methods have been proved to be very good means of modeling and optimization in complex enterprises, especially in virtual enterprises. Finally, the formulation of the translation from EEPCs to EPN is discussed.
