基于面向对象Petri网的配送业务流程建模

Distribution Process Modeling Based on Object-oriented Petri Net

要建立满足企业需求的快速、高效的流程,对流程进行建模、仿真、分析优化是一种比较科学且经济的方法。现有的研究工作,主要有IDEF系列、ECAA(事件-条件-动作规则)、Petri网等建模方法。其中,Petri网以其独特的优势而成为当今比较流行的建模方法,它既有严格的数学定义,又具有图形表示方法,可用于复杂系统建模。在介绍基本Petri网的概念后,又给出了面向对象Petri网的定义,分析了它的特点,并以面向对象Petri网作为工具,建立了配送业务流程模型,旨在以模型为基础进行流程性能分析,为流程优化提供分析手段。

Process modeling, simulation, analysis and optimizing are a kind of scientific and economic way for an enterprise to build quick and efficient processes that meet the enterprise＇s needs. From study work, modeling approaches include IDEF, ECAA, Petri Net. Among them, Petri Net becomes a popular modeling method due to its special advantages. Petri Net can used to model a complex system because it has strict mathematical definitions and graphical description. The conception of a Petri Net is firstly introduced. Then the definition of Object-oriented Petri net and its characteristics will come out. After that, distribution process will be modeled using Object-oriented Petri Net. The purpose is to analyze the performance of the process using the model later.
