Study On Engineering Construction Management And Digital Decision Analysis Based On Project Group Combination Model For South To North Water Transfer Project

Currently, the integrated decision support system for large-scale hydraulic engineering is still in the initial stage and the existing systems can not meet the requirements. Considering its features of South to North Water Transfer Project, such as long water transferring distance, large numbers of different types of structures and huge investment, the project group division combination model is constructed and its general structure is put forward, which is based on functional objects and considers hierarchy and time dimensions. The integration technology of the decision technology and project group decision support system based on knowledge is applied to the construction management of South to North Water Transfer Project. The original project group decision support system is developed, which provides theoretical and technological supports for the .improvements of the digitalization, informationization, networking and intelligentization of the construction management of South to North Water Transfer Project.The main contents and results are summarized as follows:1. By analyzing the features of the construction management, the model is proposed for the construction management of South to North Water Transfer Project, which is based on functional objects. The project group is a common object system, which is built by the balance and coordination among the multi-objects of the project. The overall structure of the project group for the construction management of South to North Water Transfer Project is constructed, which considers hierarchy and time dimensions.2. The theory and method of knowledge engineering are applied to the construction management of South to North Water Transfer Project. The key is to achieve the share, coordination and optimization of information from the angle of whole strategy of project programs by effective information management. In order to promote the communications and share of knowledge and information, the knowledge-integration platform is built using information technology and knowledge-integration technology. Based on the theory and method of knowledge and knowledge-acquiring, the structured claim treatment process is designed and the database is constructed to store large amounts of structured cases. It provides an important way for the decision users to acquire claim knowledge, especially the experience knowledge.3. A structural model is put forward for the decision support system of large-scale hydraulic engineering construction. The 3D visualized original decision support system based on project group is developed for the South to North Water Transfer Project. The system integrates real-time control of construction schedule, construction contract management, financing management, claim decision support system and etc. The system is used in some section of the mid-route of South to North Water Transfer Project.
