摘要
随着现代企业管理技术的快速发展和计算机信息技术的日新月异,企业资源计划
( Enterprise Resources Planning,ERP)思想愈来愈受到各个行业的重视,同时,在一些
生产企业已经得到普遍和深入的应用。采购管理系统作为企业资源计划系统的重要组成
部分,能够保证生产计划的科学性、预见性、准确性和采购的及时性、合理性、经济性,
可以改善并提高企业的管理水平,提升企业的竞争力。玻璃深加工行业作为制造业中一
个新兴行业,其生产经营过程兼有连续和离散的特点,生产过程复杂,品种规格繁多,
从而也使采购工作难度加大。因此,针对玻璃深加工行业的ERP采购管理系统进行研究
具有非常重要的意义。
本文根据XSJ玻璃钢化有限公司信息化工程项目,描述了国内外ERP的发展现状
和趋势,总结了玻璃深加工行业的特点和需求状况。通过研究采购管理的相关理论,比
较了传统采购理论和ERP模式下的采购理论。介绍了UML( Unified Modeling Language)
统一建模语言的主要内容,设计了适合XSJ公司ERP采购管理系统的组织结构、业务
流程和功能模块,创建了静态和动态视图,详细描述了整个建模流程,并对玻璃深加工
行业的MRP分解算法和切裁算法做出一定分析。阐述了C/S( Client/Server客户机/服务
器)模式下的三层体系结构主要原理和特点,确定了系统总体设计框架和窗体模式。运
用 DELPHI7.0为开发工具和 Microsoft SQL server2000作为数据库,设计出适合该企业
的采购管理系统,实现了系统的部分功能。

ABSTRACT
With the development of Internet technology and business management, ERP(Enterprise
Resources Planning )has been widely and intensively used in factories and companies
Purchasing Management System, as an important part of ERP, can help to improve the
scientificalness, farsightedness and accuracy of purchase activities. It also helps to guarantee
the timeliness, sensibility and economy of purchase behaviors. All these can enhance the
management ability and competitiveness of companies and factories. Glass Deep-processing
is an emerging manufacturin industry. Its production process is a successive one and also an
intermittent one, which is very complex and the products are rich in types and large in amount,
resulting in more difficulty in purchasing link. So it's of great importance to make a research
of the ERP applied to the purchasing link of this industry
Based on Information Update Project of XS J Co. Ltd, this paper describes the modem
development and the future of the ERP at home and abroad. It makes some conclusions about
the characteristic and demand situation of this glass deep-processing industry. The author
learned the theory of purchasing management and compares the classical purchasing theory in
the ERP pattern. This paper contains an introduction of UML(Unified Modeling Language
and the authors analysis about the MRP decomposing algorithm, cut algorithm used in the
glass deep-processing industry. It designs an ERP purchasing management system
including its structure, process and template for the XSJ Co. Ltd. The author builds the static
and dynamic view of the system and gives details about the whole modeling procedure. It
explains the main principle and feature of the three-leveled patterns in the C/S(Client/Server)
mode. It fixes the framework and the form model for the design of the syster. By using
DELPHI7.0 and Microsoft SQL server 2000 as tools the author has designed the purchasing
management system and also activates some functions of the system
