构造可扩展工作流的语义机制模型伍轶明 姚绍文 LU Zhong-yu


  摘 要:为了提高复杂多样的应用环境下的工作流性能,基于Petri网构建块定义了工作流元对象模型和工作流领域本体OWL-W,在传统工作流系统中引入了元对象协议,构造了一种新的面向语义的工作流模型;在此基础上讨论了一种基于多agent的软件架构来实现面向语义的工作流机制,说明了面向语义的工作流对于提高传统工作流的灵活性和可扩展性是有效的。

  Abstract:

  For improving flexibility and scalability of workflow system in complex and diversified application context, this paper defined a model of meta-object based on Petri-net building block and a workflow ontology named OWL-W based on OWL, model a new semantic architecture of scalable workflow by importing meta-object protocol to traditional workflow system. Furthermore, represented a method based on multi-agent to implement mechanism of semantic oriented workflow here, which shows that the mechanism of semantic architecture of workflow is effective to improve the flexibility and scalability of traditional workflow.
