企业资源计划论文：ERP系统流程模块重用的设计与实现 【中文摘要】NFERP项目中流程是由BPEL4WS通过对现有的Web服务,外加Web服务用户自行开发的判断逻辑Web服务进行调用而实现的。它有效的利用了已有资源,并结合了SOA理论的优点,可以方便的调用基于SOA架构的中间件,大大的提高了项开发速率和模块化的复用度。本文介绍了解企业资源计划(简称ERP)技术发展、ERP实施过程中遇到的模块重用以及与其他系统整合等问题、SOA架构的优势与商业可执行流程语言(BPEL4WS)相关内容、利用BPEL4WS解决模块重用问题等。最后通过江苏常州市南方轴随厂的NFERP实施为依据,介绍利用BEPL4WS进行ERP系统中的模块重用。本文重点介绍了BPEL4WS的技术的使用方法和Web服务调用方式。通过对NFERP实施过程中对生产管理流程中的排产流程详细介绍,描述了BPEL4WS在实际流程实现的原理和编写过程。排产过程是NFERP生产管理子系统中最为复杂的一个系统。由于其独立于平台之外的特点,使得可以充分的发挥以往积累下来的业务逻辑模块的作用,而无需重新编程。根据当今企业发展的趋势论述SOA的架构思想在企业信息化发展中所起到的作用。 【英文摘要】The process of NFERP is realized by BPEL4WS’transferring existing Web service and the user’s development of Web service. It makes good use of existing resources and integrates the advantages of SOA theory, so it can invoke the middleware based on SOA .As a result, it will improve the development rate of the project and the modular multiplexing degrees.This thesis discusses how to realize the reuse of ERP (Enterprise Resource Planning) by using BPEL4WS (Business Process Executive Language for Web Service) from the following aspects: knowing technology development of ERP, the problems occurred in the process of ERP implement, the advantage of SOA (Service Oriented Architecture) and something related to BPEL4WS, solving module reusing problems by using BPEL4WS. The thesis discusses how to solve module reusing problems by using BPEL4WS based on the implement of NFERP in South Axis Company, Changzhou, Jiangsu Province.The thesis mainly introduces the usage of BPEL4WS and Web service. It tries to describe the programming of BPEL4WS and its realization principle by introducing the production scheduling process in using NFERP.The production scheduling process is the most complicated system in the NFERP manufacturing management. Because of its characteristics outside the independent, platform, it can make full use of its function of business logic module accumulated before and need not reprogramming.Finally, it expounds the SOA playing an extremely important ro
