【摘要】 随着信息化技术的不断深入,计算机技术已经渗入到企业生产运行的各个环节。工作流是业务过程中的一个计算机实现,广泛应用于办公、生产和制造等领域,在企业信息化建设中工作流发挥了越来越重要的作用。然而,由于工作流是业务过程的抽象,大多以静态、固化的形式表现,相应的传统的工作流管理系统存在着适用范围窄、灵活性差等方面的不足,以至于不能对活动中的任务实现过程重构,使得系统的应用受到很大限制。本文对工作流技术的发展状况、存在的缺陷和不足等方面进行了分析研究。在工作流系统中引入人工智能领域中的规则引擎,将业务流程与业务规则分离,可以改善工作流流程定制的僵化问题。文中首先概括了工作流及工作流管理系统的基本概念,阐述了工作流管理系统的研究现状;然后介绍了SAP及其NetWeaver技术平台和工作流技术;最后通过规则引擎与工作流引擎的交互,借助规则库中的规则,自动产生和运行整个工作流。降低了工作流系统中业务修改的复杂度,同时也提高了流程执行效率,完成了工作流过程的自动流转。本文建立了基于NetWeaver平台的智能工作流系统,通过应用在电力企业ERP项目中,提高了电力企业纷繁复杂的日常审批类业务的工作效率,最后通过物料主数据审批流程验证了该系统的可行性。更多还原

【Abstract】 With the depth of information technology, computer technology has penetrated into production of enterprise. Workflow is a computer implementation in the business process; it is widely used in the field of office, production and manufacturing. Workflow plays more and more important rules in informational construction of enterprise. However, workflow is an abstraction of the business process; it mostly performs static and curing forms. Because the traditional workflow management system exist the shortage of narrow application and poor flexibility, it can not realize the procedural reconstruction in the task of activities. These make that the application of the system is very limited.This paper researches and analyzes the development situation and the shortcomings of the workflow technology. The rule engine which belongs to the field of artificial intelligence is introduced to the workflow system; the system realizes the separation of business flow and business rules and improves the rigid issue of workflow process. Firstly, this paper generalizes the basic concepts of workflow and workflow management system and expounds the status of workflow management system, and then SAP NetWeaver technology platform and the SAP workflow technology are introduced. Finally, by the interaction of the rules engine and workflow engine and the help of the rules, the system can automatically generate and run the entire workflow. The modification of the business becomes simple and the efficiency of the process execution is enhanced. Workflow process can realize the turnover of automatic.In this paper, the intelligent workflow system based on the NetWeaver platform is established. The work efficiency of the electric power enterprise is improved, and the feasibility of the system is verified by the approval process of the material master data.更多还原
