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 modeling 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.
