【摘要】 随着信息技术、网络技术的不断发展和建设领域工程交易活动日趋活跃,有形建筑市场正由传统的、手工为主的、受地域限制的封闭交易模式,向现代的、电子化的、基于网络的开放交易模式转型,一个全新的、依托于网络进行建设工程电子交易的模式已成为关注热点。本文以杭州地区建设工程交易电子化、网络化的研究为背景,提出了基于ASP模式的建设工程电子交易平台的体系结构,通过多资质判断算法、数据同步更新机制和面向多用户核心管理机制等关键技术的研究与实现,解决统一网上报名和远程信息发布的问题,构建杭州地区跨部门、跨地区、跨行业的电子交易服务。论文内容安排如下:第一部分,绪论。主要介绍建设事业信息化的研究现状和论文的研究背景,包括国内外建设事业信息化的发展状况和发展趋势,建设工程交易的职能、交易电子化的需求和本文的研究背景。在此基础上提出了本文的研究目标与研究内容。第二部分,提出了基于ASP模式的建设工程电子交易平台的体系结构。首先分析了杭州地区建设工程交易信息化现状,结合电子政务的发展规划,提出了实现四个互联的电子交易平台的网络结构;然后根据交易电子化、网络化的需求,提出了电子交易平台的体系结构。第三部分,研究ASP模式的核心管理机制。在分析电子交易平台所承载的交易对象、交易类型、服务类型和服务用户的基本情况,提出了ASP模式用户管理和服务管理的核心管理机制,着重研究了日志管理的关键技术事件审计跟踪功能。第四部分,研究网上资质预审服务和CI4S短信服务的实现。设计实现了网上资质预审服务的功能和流程,提出关键技术多资质判断算法;分析和介绍短信相关协议和消息流程,设计了CI4S短信服务功能,提出了与SP合作方式的服务解决方案。第五部分,研究数据服务层的构建。通过分析电子交易平台对信息资源共享和远程信息发布的需求,提出了关键技术数据同步更新机制,解决了在公众互联网中实现数据库访问的安全性问题,重点论述了数据传输过程中结果集的重构技术。第六部分,实例。在充分论述基于ASP的建设工程电子交易平台所采用关键技术的基础上,本文给出几个具体的应用服务实例,进一步论证电子交易平台的关键技术在提供实际服务中的有效性、灵活性和安全性。最后,对基于ASP的建设工程电子交易平台技术的研究进行总结,并对面向建设工程领域电子交易技术的发展趋势进行了展望。
【Abstract】 With development of the computer, information and network technologies, as well as the trade of project in field of construction getting activity, the corporeal construction market is converting from conventional, primary by handwork, restricted by tract and close trading-mode into modern, electronic, network-based and exoteric trading-mode. A new and network-based trading-mode has been a focus of attention.The thesis proposes the architecture of the construction project electronic-trading-Platform based on ASP mode, which adapts itself to the requirement of electronic trade in the field of construction project in Hangzhou. The key technologies of Multi-Qualification Prejudication, core Management Mechanism and synchronous Data Update Mechanism are researched and implement.At first, a systematic survey of electronic trade research in the domain of constration project is given, including correlative vocation information, service mode, the tendency and requirement of electronic trade in the domain of construction project, and then the study objectives and contents of this thesis are presented.Secondly, the thesis proposes the architecture of the ASP-based construction project electronic-trading-Platform. According to the different functions, the whole system is divided into six layers: user interface, decision-making sustainment, core management, application service, data service and infrastructure.Thirdly, base on the analysis of the complexity and security of construction project trade at present and the multiformity of application service, the thesis proposes the core Management Mechanism including multiuser-oriented user management and service management. The key technology, Event Audit Tract of log management, is the emphases of this part.Fourthly, there are two application services, Short Message Service and Qualification Prejudication Service, which are discussed. The thesis proposes the key technology, Multi-qualification judgement arithmetic, and the project of cooperation with SP.Fifthly, synchronous data updating mechanism is discussed as the key technology of data service layer to support application services.Sixthly, several practical application services, is shown as the example. It proves the feasibility and efficiency of the technology discussed in this thesis, which enables the applacation services and managing tools on construction electronic-trading Platform.Finally, this thesis makes a conclusion about ASP-based construction project electronic-trading-Platform and its development tendency in the future.
