【摘要】 作为一类典型的CSCW系统,工作流管理系统主要提供异步、结构化的协同支持。本文从模型入手,介绍了一种基于Petri网的工作流模型——同步网。它采用分层视图描述了过程逻辑、语义及管理,过程模型和管理模型的互动关系用来指导工作流引擎的构造。本文基于同步网开发了工作流管理系统,支持工作流的定义、执行和管理。为了满足CSCW的需要,工作流管理系统中增加了同步协作机制。更多还原

【Abstract】 As a typical CSCW system,workflow management system mainly provides asynchronous and structural cooperative support.This paper starts from the model,with introduction to a Petri-net based workflow model,that is, synchronization net.The model describes process logic, semantics and management from three-layer perspective, in which the interactions between process model and management model give help to construction of workflow engines.Based on synchronization net,we have developed a workflow management system, supporting the definition, execution and management of workflow.For the need of CSCW,some synchronous cooperative mechanisms are introduced.更多还原
