摘 要
【摘要】随着经济全球化和知识经济时代的到来,无国界化企业经营的趋势越来越明显,整个市场竞争呈现出明显的国际化和一体化。与此同时,用户需求愈加突出个性化,导致不确定性不断增加。此外,高新技求的迅猛发展提高了生产效率,缩短了产品更新换代周期,加剧了市场竞争的激烈程度。这些促使核心企业需要加强供应商管理。通过优势互补和协同效应产生企业独立时所不能产生的优势,也就是通过建立合作伙伴关系双方都能从提高生产率、节约资源、降低成本中获益,同时创造更大的顾客价值。所以为了适应市场与客户的需求,企业迫切需要构建一个供应商选择决策系统有效地对供应商进行评价、筛选,加强企业与供应商间的合作交流,从而建立新的竞争优势。
此系统设计上采用三层结构、Web Service技术,使之在选用平台、采用技术上具有先进性、前瞻性、扩充性,从而保证建成的系统具有良好的稳定性、可扩充性。系统设计按标准化、规范化,分层设计,构件化实现。采用软件构件化的开发方式,使系统结构分层,业务与实现分离,逻辑与数据分离;以统一的服务接口规范为核心,使用开放标准。从功能上来说,系统是比较完备的,系统以Web界面与用户交互,为用户提供信息并接受其操作,同时通过数据库管理系统来存储信息数据。系统实现了对信息数据的浏览、查询、编辑和管理等基本数据库操作,采用了模块化设计方法,根据用户的需求及程序的应用与维护的易用性,将各个部分置于不同的模块当中,方便了程序的扩展与维护,同时建立了程序功能复用的基础。

【 abstract 】 with the economic globalization and the coming of the knowledge economy time, the trend of enterprise operation without borders is more and more obvious, the whole market competition displays obvious internationalization and integration. At the same time, the user needs increasingly prominent personalized, leading to uncertainty increasing. In addition, the rapid development of high and new technology for increasing the production efficiency and shortened product renewal cycle, increasing the market competition intensity. These core enterprise need to strengthen supplier management. Through the complementary advantages and synergy effect when the enterprise independent cannot produce advantage, also is through a partnership, both sides can improve productivity, from the conservation of resources, reduce the cost benefit at the same time, create more value for customers. So in order to adapt to the market and the demand of customer, the enterprise the urgent need to construct a supplier selection decision system effectively to evaluate suppliers, screening, strengthen the cooperation between the enterprises and suppliers communication, so as to establish a new competitive advantage.
This system the design of three layer structure, Web Service technology, make in selecting a platform, and the use of technology has advanced, forward-looking, scalable, built in order to ensure that the system has a good stability and extensibility. System design on a standardized, standardization, layering design, realization components. With the development of software components way, make the system structure layered, business and separated, logic and data apart; In a unified service interface standard as the core, the use of open standards. From the function for, the system is more complete, the system to Web interface and the user interaction, to provide information and accept its operation, and at the same time through a database management system to store information data. The system of information of the data to browse, search, editing and management, and other basic database operation, using modular design method, according to the needs of the users and the application of the program and maintenance of the facility, and each part in different will of module, convenient maintenance and expansion of the program, also established the program function reuse foundation.
