基于Petri网的工作流模式--工作流模式分析研究

随着企业建模、工作流概念的出现以及相关技术的发展,Petri网因其既有严格的形式定义,又有直观的图形表示,既有丰富的系统描述手段和系统行为分析技术,又为计算机科学提供坚实的概念基础等诸多优点也被应用于这一新兴领域,对工作流理论基础进行研究.本文将利用Petri网来描述和分析工作流的各种模式,比较模式之间的异同,并对模式进行合并和重划分.

Workflow Patterns based on Petri Nets-- A Study of Workflow Patterns

With the development of several technologies, such as business process modeling and business process coordination and so on, Petri Nets is introduced to the field of the workflow because of formal semantics beside the graphical nature, states-based instead of event-based and abundance of analysis techniques. This Paper describes and analyses the workflow patterns by using Petri Nets in order to find the same and different characters among them. And according to these characters Workflow Patterns will be regrouped and partitioned.
