【摘要】：政府采购工作一直是政府的重要职能之一,在西方发达国家,政府电子采购方式日益得到了重视和普遍应用。然而在国内,由于网络基础设施薄弱等客观原因,政府电子采购方式仍然处于初级阶段。综上所述,如何搭建一个高效,可扩展,功能相对全面的政府采购平台是一项迫在眉睫的问题。运行高效并且功能可扩展的政府采购应用平台是目前正在研究的热点问题。为了有效增强政府采购工作的透明度,提高政府财政资金的利用效率。加强财政支出科学管理,积极推行政府采购制度,最终做到政府的公正,公平,公开。本课题所实现的网络采购管理系统是通过引入先进的计算机管理方法,将基本信息管理,政府采购招标流程以及相关辅助管理模块联系在一起,努力提高工作效率,实现信息公开化,交易现代化,使其设计成为一套广域网与局域网相互结合的现代化管理信息系统。本文是严格按照面向对象的设计思想进行应用程序的设计与实现,将现代信息技术与政府采购业务紧密结合。论文根据RBAC模型理论详细描述了系统用户群,从而将系统用户主要划分成评审专家,代理机构,供应商,采购人等基本角色,接着分别针对多个系统角色需求进行描述与说明。根据系统三层体系架构理论将本系统划分成数据层,功能层以及表示层,在功能层的设计过程当中根据业务基本需求,相继完成了系统管理、电子合同、电子招投标、电子反拍、协议订购等业务功能模块的设计工作,绘制了系统总体层次图。文中利用流程图的形式反映了电子招投标模块,电子反拍模块,协议订购模块的业务操作流程,并且在电子招投标模块当中陆续增加了指定代理机构以及随机抽取功能,利用系统接口在系统当中加入了数字证书以及直接以专家库抽取专家等创新性业务。论文对系统当中存在的各种实体进行了详细分析,利用E-R图对后台数据库概念结构进行了展示,最后以电子招投标业务当中的中标公告表,开标一览表以及采购项目列表作为例子,展现了系统数据库的逻辑结构设计。在本文的最后,对本课题所开发的电子化采购系统进行了详尽的功能与性能测试。测试结果表明,系统基本能满足政府采购业务需求。
[Abstract]:Government procurement has always been one of the important functions of government. In western developed countries, government electronic procurement has been paid more and more attention and widely used. However, due to the weak network infrastructure in China, government electronic procurement is still in its infancy. To sum up, how to build an efficient, extensible, relatively comprehensive government procurement platform is an urgent problem. Efficient and scalable government procurement application platform is a hot issue. In order to effectively enhance the transparency of government procurement, improve the efficiency of the use of government financial funds. Strengthen the scientific management of fiscal expenditure, actively promote the system of government procurement, and finally achieve the fairness, fairness and openness of the government. The network purchasing management system realized in this subject is to improve the working efficiency by introducing the advanced computer management method, connecting the basic information management, the bidding process of the government procurement and the related assistant management module together. The realization of information openness and transaction modernization makes it a modern management information system which combines WAN and LAN. In this paper, the application program is designed and implemented strictly according to the object oriented design idea, and the modern information technology is closely combined with the government procurement business. According to the theory of RBAC model, the system user group is described in detail in this paper, and the system user is divided into the basic roles of expert, agent, supplier, purchaser and so on. Then, the system users are described and explained according to the requirements of multiple system roles. According to the theory of system three-tier architecture, the system is divided into data layer, function layer and presentation layer. In the design process of function layer, according to the basic business requirements, the system management, electronic contract, electronic bidding have been completed one after another. Electronic reverse shooting, protocol ordering and other business function module design work, draw the overall system hierarchy diagram. In this paper, the flow chart is used to reflect the business operation flow of the electronic bidding module, the electronic reverse shooting module, the protocol ordering module, and the designated agency and random selection function have been added to the electronic bidding module one after another. The system interface is used to add digital certificate to the system and to extract experts directly from expert database. In this paper, the various entities in the system are analyzed in detail, and the conceptual structure of the backstage database is displayed by using E-R diagram. Finally, the successful bidding announcement form is used in the electronic bidding business. The list of bid opening and the list of purchasing items are used as examples to show the logical structure design of the system database. At the end of this paper, the function and performance of the electronic procurement system are tested in detail. The test results show that the system can basically meet the needs of government procurement business.
