面向对象的虚拟组织集成建模方法

Object-oriented method for virtual organization integrated modeling

提出了一种适应虚拟组织业务过程动态变化的虚拟组织集成建模方法(VOIM,Virtual Organization Integrated modeling),该方法集标准化面向对象的建模语言(UML,Unified Modeling Language)、功能建模集成化定义方法(IDEF0,Integration Definition for Function Modeling)和事件驱动过程链(EPC,Event-driven Process Chain)为一体,以弥补单一方法的不足,适合复杂系统特别是虚拟组织的建模,其中:IDEF0对虚拟组织的功能建模,EPC对功能视图进行细化,UML通过实体映射关系把虚拟组织模型的各个视图有机结合起来,有利于实现系统的模块化和模型的重用;同时对建模过程中UML到EPC之间的转换方法进行了研究.最后对模型进行了形式化描述,从而使VOIM具备严格定义的抽象语法和语义,为模型的验证和仿真提供了良好的基础.

These integrated modeling methods named virtual organization integrated modeling（VOIM） were discussed,which can be used for agile virtual organizations process dynamic optimization.These methods were integrated by unified modeling language（UML）,the methodologies of integration definition for function modeling（IDEF0） and event-driven process chain（EPC）.The combination of these methods means that the weaknesses of each can be counteracted by the strengths of others.These methods were proved to be very good means of modeling and optimization in complex systems,especially in virtual organization,in which IDEF0 modeling the function view of virtual organization,EPC refining the function view,and UML combining the various views of the virtual organization through the entities mapping relationship.It is conducive to achieving the system＇s modularity and the reusability of the model.The translation from UML to EPC was discussed.Finally,the models were described formally,consequently made the syntax and semantics of VOIM defined strictly,and provided a good foundation for validation and simulation.
