Construction Project Electronic-trading-Platform Based On ASP

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.
