政府审批工作流引擎设计与实现.docVIP

西安电子科技大学 摘 要 近几年来工作流技术在很多行业中得到了普遍应用。它将实际的业务逻辑抽象建模，形成计算机可以识别和应用的数据模型，用计算机的智能自动化处理取代或者部分取代人工处理，大大提高了工作效率。工作流引擎是整个工作流技术的核心，工作流引擎通过流程定义，流程规则解析等来实现流程工作的自动化。 本文以青岛市政府网上审批项目为背景，研究了电子政务审批业务的实际需求，结合工作流理论和技术，设计并实现了一套针对政府网上审批的工作流引擎。从而实现了网上审批取代传统的人工审批的方式。本文分析了政府审批工作流引擎的体系结构，详细设计了工作流程在运行态的组成元素和工作流引擎中关键对象及模型，介绍了流程定制工具和流程状态控制的设计，给出了政府审批工作流引擎的总体实现。最后通过一个具体的审批实例，验证了政府审批工作流引擎的可靠性和有效性。 关键词：工作流 工作流引擎 流程定制 电子政务Abstract In recent years, workflow technology has been used widely in many industries. It will abstract the actual business logic to develop a data model which can be identified and applied by computer. it replaces or partly replaces the way of manual handling by the why of intelligent automation handling of the computer,so enhance working efficiency greatly. Workflow engine is the core of the workflow technology, workflow engine through the process definition, process analysis, and other rules to achieve the work flow automation. This paper is in the background of Qingdao Municipal Government for approval project on-line, researching the actual requirement of the e-government approval business, combinating the theory and the technology of workflow,designing and implementing a set of workflow engine for the goverment approval work on line. so the method of approval on-line is able to replace the method of traditional manual approval. This paper analyzes the archietecture of the governments approval workflow engine, designs the elements of the workflow running in the state and key objects and models of the workflow engine in particular, introduces the custom tools of the workflow and the state controlling designs of the workflow,achieves to give the final and entire government approval workflow engine. At last, It verifys the reliablity and validity of government approval workflow engine through a specific example. Key words : work flow,workflow engine, workflow customization, e-government 目录 第一章 绪论 1 1.1 论文的研究背景和目的 1 1.2 相关国内外研究现状 1 1.3 论文的研究内容 2 1.4 论文的结构安排 3 第二章 工
