【摘要】 近年来,我国电力基建工程的投资不断增长,复杂的基建业务需要借助信息系统进行有效的管理。企业资源计划(ERP)是一个集组织模型、业务流程、企业规范和信息技术为一体信息系统,它包含了先进的管理思想。电力基建ERP就是针对电力行业基建期的业务特点进行设计开发的ERP系统。本文以上海外高桥电厂和内蒙古托克托电厂为实例,在对基建ERP开发采用的技术及其总体框架进行深入探讨的基础上,针对电力基建ERP的核心模块——合同管理模块进行了完整的系统分析和设计,并进行了部分模块的编程。在合同模块的设计中采用了两项新的技术——弹性域和工作流。弹性域是Oracle ERP应用平台采用的一项关键技术之一,主要包括关键弹性域和描述弹性域,它能提供可自定义的“扩展空间”和灵活的编码方式。合同模块的数据库设计中融入了弹性域的思想。国家863计划提出的新一代ERP系统的标准中,明确要求以工作流引擎为基础,加强流程控制与事务处理系统的集成。合同模块的业务流程设计主要采用工作流技术。本课题不仅是对ERP系统在电力行业应用实例的研究,而且在系统设计中采用的新技术----工作流和弹性域,是系统设计的一次新的尝试,具有一般参考意义。更多还原

【Abstract】 The average annual investment in capital construction in China increased rapidly in recent years. The management of electric power capital construction is so complicated that it is necessary to using advanced software. Enterprise Resource Planning (ERP) is a information system which include the organization structure, business process organization, enterprise criterion and information technology. Electric capital construction ERP was designed and developed for the purpose of applying to electric capital construction.Waigaoqiao Power Plant in Shanghai and Tuoketuo Electric Power Generation Company in Neimenggu were researched as the example in the thesis. Based on the research in technology and system frame of capital construction ERP, I had performed the whole analysis and design of contract management module, which is the core module of electric capital construction ERP. Additionally, partial coding work of contract module has been finished.There are two new technologies being used, one is Flexfield, the other is Workflow. Flexfield is one key technology of Oracle ERP application platform. Two types of flexfield are provided: key flexfield, which has flexibility built into it so that users can define reporting structures, and descriptive flexfield, which are user-defined and record data elements that aren’t automatically provided. The database of contract module is designed with flex field thought. According to research project of National 863 Plan the second-generation ERP system should be based on workflow engine technology. The system was built with workflow technology in contract module. The research project is the electric industry application instance of ERP. There are use two new technology, i.e. workflow and flexfield in the project. The experience will be a great reference for other system.更多还原
