Research Of TieTong Planning And Construction Management Information System Based On Workflow

With the rapid development of the computer technology and the network application, informationalization has become the necessary condition of the modern enterprises. Convenient and efficient management information system has become an integral part of the government agencies and enterprises which can improve office efficiency. With the rapid expansion of the scale and variety of TieTong business, the quality requirement of the department work is increasing day by day. Therefore, it is indeed critical to start the information construction to ensure the efficient business operations and the overall system's reliability, security and scalability. This thesis has raised a set of solutions for TieTong Planning and Construction management information system. The main work and innovations are as follows:Functionally, the monitoring and management of the daily work in the Planning and Construction departments is realized based on B / S mode with relatively complete functions. Through this system, Planning department people can conveniently manage and handle the project applications; Construction department people can monitor and control the series of work process involving project building, such as project preparation, design, construction, inspection and so on; Management people could maintain the users' information, their roles and authorities through the system. And also they could access the real-time system log information which is very helpful to efficiently and rapidly monitor it. The daily work efficiency and quality of Tietong Planning and Construction department could be highly improved and the long-term, stable operation of department business is ensured by using the system.Technically, in this paper, the status and direction of the development of workflow technology and Petri net modeling is investigated, followed by the analysis of business functions and data standards in TieTong Planning and Construction departments; the key technologies and their implementation in the system are particularly studied; the solutions of TieTong Planning and Construction management information system based on Petri net workflow are finally completed. The popular workflow technology in the industry is applied in the TieTong system and its workflow modeling is also completed based on Petri net technology with the authentication of the model's correctness. In the realization of the system, the workflow engine and its business application interfaces are realized based on the Relational database; the multi-layer role based access control and multi-user concurrent mechanism in the system are also proposed and implemented; advanced .NET framework and ASP technology are imported which is indeed helpful for the optimization of the system's front-end display and function implementation.A relatively comprehensive TieTong Planning and Construction management information system based on workflow has been established in this thesis, which has achieved the prospective design objectives and functional requirements.
