基于面向对象Petri网的工作流建模及性能分析

工作流技术作为一种过程建模和过程管理的核心技术，在计算机应用领域获得了迅速的发展。介绍了工作流技术；提出了将面向对象建模技术融入Petri网模型所形成的面向对象Petri网，并讨论了建立基于面向对象Petri网的工作流模型的步骤；运用面向对象Petri网建立了某制造企业的产品方案处理流程的工作流模型，并运用性能等价公式对工作流模型的性能进行了分析。

Workflow Modeling and Performance Analysis Based on Object- Oriented Petri Nets

As a core technology in process modding and process management, workflow technology, has acquired a rapid development in computer application. In this paper, workflow technology is introduced firstly. After that,object- oriented Petri nets,which can be established by applying the object - oriented modeling, is proposed, and then the approach of setting up workflow model based on object - oriented Petri nets is discussed. Finally, a workflow model of product scenario process in a manufacturing enterprise is developed,and the performance of workflow is analyzed by means of performance equivalence equations,
