【摘要】 工作流(Workflow)的概念是企业管理(Enterprise Management)中为提高工作效率而产生的，它通过先进的电子通讯和网络技术，尽量使得企业中并行任务的执行过程能够线性化。它涉及到机械、管理、信息、计算机科学等多个领域，被广泛应用于电子商务、产品设计、远程教育等多个方面。目前，基于Web的工作流管理系统已经成为工作流管理系统中的研究热点和前沿领域，并显示出良好的发展前景。 本文介绍了工作流的起源与发展，在从不同的角度对工作流概念进行描述的基础上给出了工作流的定义；通过对典型工作流产品进行整理、归纳，对工作流管理系统进行了分类；探讨了工作流系统存在的问题及研究热点。同时在对工作流基本概念及相互关系、工作流参考模型进行阐述的基础上提出了具体的工作流系统的体系结构。经过分析、比较，本文采用面向对象建模方法对基于Web的工作流管理系统进行建模。 本文详细阐述了CORBA技术体系结构中的ORB(Objeft Request Broker)核心、IDL(Interface Definition Language)、对象适配器OA(Object Adapter)、IDL stub与IDL skeleton、动态调用接口DII(Dynamic Invocation Interface)与动态构架接口DSI(Dynamic Steleton Interface)和Web技术中有关HTTP协议、脚本语言开发、Web对象计算机体系和Web安全技术等关键技术及在基于Web的工作流管理系统的应用。 系统采用基于三层B／S／D的结构，利用面向对象技术，提出了基于Web的工作流管理系统的具体实现放方案。介绍了系统的实现环境和体系结构，系统中所采用的数据库结构，阐述了过程定义工具的设计和管理监控工具的设计等。 最后，总结全文，并针对当前工作流技术发展情况，对工作流技术的发展进行了展望。更多还原

【Abstract】 The concept of workflow is put forward for improving work efficiency in enterprise management. Through electronic communication and network technology, it makes the process of execution of concurrent assignment in enterprise be linear. It relate to several domains such as mechanism, management, information, science of computer and so on. And it is applied in many aspects such as electronic commerce, product design, remote education, etc. Now, web-based workflow management system has become the focus of research and advanced domain in workflow management systemThis paper introduces origin and development of workflow, gives definition of workflow based on describing workflow conception from various views. The author classifies workflow management and discusses the problem and hotspot of workflow system based on analyzing concluding typical workflow system product With expounding the basic concept of workflow and correlative relationship, workflow reference model, this paper gives idiographic workflow system framework. Through analyzing and comparing, web-based workflow management system is modeled with object-oriented modeling technology.This paper expounds key technologies such as ORB(Object Request Broker), IDL(Interface Definition Language), OA(Object Adapter), IDL stub, IDL skeleton, DII(Dynamic Invocation Interface), DSI(Dynamic Steleton Interface) of CORBA technology system framework and HTTP protocol, script language programming, web object computer system and web security technology of web technology. The author researches the application of these technologies in web-based workflow management system.This paper describes in detail the realization of web-based workflow management system with three layers B/S/D configuration and Object-Oriented technology. It describes the system’s realization environment and framework, describes database configuration in the system, expounds the design of process define tool and management control tool.Finally, the paper is summarized. According to the development of workflowtechnology at present, this paper forecasts the development of workflow technology in the future.更多还原
