【摘要】 作为一个新兴的研究领域，工作流技术已经被广泛应用于生产制造、办公自动化、并行工程、电子政务等领域，是实现企业业务过程建模、优化、过程管理与集成，最终实现业务过程自动化的核心技术。工作流技术的实施已经成为企业完善经营过程、提高自身竞争力的一种重要手段。Petri网系统是一种适合于描述异步并发现象的计算机模型，具有坚实的理论基础和成熟的分析技术，利用Petrj网建立的模型有着良好的直观图形和有力的分析技术支持，因此可以使用Petri网对工作流建立模型，使得建立的工作流过程既明显直观，又可以保证过程的正确性。本文研究了工作流技术在公文流转系统中的应用，结合实际应用环境，提出了一个基于Petri网的公文流转工作流模型。并对该模型进行了数学分析和可行性分析，确保模型的正确性和实用性。同时该模型在功能和接口设计方面严格遵守工作流管理联盟(WfMC)提出的工作流参考模型标准。论文重点论述了按照Petri网原理建立的工作流模型在J2EE框架下的实现，在系统体系结构的框架上进行了详细的功能模块设计、数据库设计和用户界面设计，并对系统的安全性设计作了说明。论文同时进行了技术重点和系统实现的论述，主要包括Struts框架应用及其它关键技术，并对系统整体程序结构和系统的不足之处及改善构想作了说明。更多还原

【Abstract】 Workflow technology, as a new research field, has being widely appliedin the fields of manufacturing, office automation, concurrent engineering,electronic government and so on. It is the key technology to realize modeling,optimizing, managing and integrating of enterprises’ business process and alsothe automation of business process. The workflow technology has become animportant method to smooth the business process and improve thecompetitiveness of enterprises.Petri Nets System is an advanced tool to describe asynchronies combutingmodel, since that time it has been studied in depth, and possess stapilitytheory basis andanalyses technology. A workflow model based on Petri Net canbe frankly examined and powerful supported a model of workflow process, soit can be provided distinct and correct.This paper researches the application of Workflow technology in OfficialDocument System, according to the actual conditions, Petri-net was chosen asa tool for Workflow modeling, and its route structure and trigger mechanismof Workflow were introduced to the modeling course.The paper dissusses the model’s realization on the J2EE framework thedatabase design, user interface design and system security design. The paperdiscusses the key technology and the realization of the system, including therealization of the Struts framework and also including other key techniquesand the whole structure of the system.The paper also summarizes the conclusion and the characteristic of thesystem, points out the deficiency of current system and bring forward someimproveing idea.更多还原
