Inter-basin Water Transfer Project becomes necessity because nonuniformity of water resources distribution and water requirement exists objectively in Human Society. Study on operation decision-making and management pattern in Inter-basin Water Transfer Syetem is an important task for water resources at three levels: rational utilization, optimum distribution, promotion of advantages with avoiding its evils. Based on the composition and characteristies of Inter-basin Water Transfer Syetem, aiming at the current issues that lack of unified and effective management system and ignore forecasting information. So we do the research on operation decision-making and management pattern and obtain the following research results:(1) Aiming at the previous questions that water transfer principle determination based on the tendays and monthly runoff series, almost without regard to floodprocess information; make flood process homogenize. Therefore, the water transfer principles do not conform to reality; the all time design constraints of water level is low, so water wasteis the ievitable result. To deal with these issues, the optimum operation decision principle method of Inter-basin Water Transfer System are presented based on promotion of advantages and flood control continuous operation style in single reservoir. It amalgamated Genetic Algorithm Long-Term Runoff Serials method, operation principle is presented based on promotion of advantages and flood control information, that is deal with the questions under total information condition. GA can organize optimum search processes using group style, parallel processing many local peaking of the object function, the possibilities of slipping into local optima are falling off, the searching speed is quickly, little EMS memory, high optimizing efficiency. It is an effective self-adaptive random searching algorithm and help decider to make scientific and correct choice. The optimum operation decision principle can provide scientific decision support for decision-makers.(2) It is a complicated system engineering to select the best water supply scheme, it belongs to a multi-objective optimization and decision process. A water supply supply schemes fuzzy optimum selection method is proposed by adopting weigh trend coefficient as evaluating indicator for the organic combination between experience weight and objective developing trend of Inter-basin Water Transfer Project system. It demonstrated from the application in engineering this method which consider not only the experience and will of decision-makers, but also the objective development trend of the matter makes the results more reasonable and remedy the deficiency in former design.(3) Aiming at the current problem that planned-water supply style and principle was used in Inter-basin Water Transfer System but lack the forecasting information. This paper first statistics 10-day forecasting rainfall distribution information issued from Global Forecasting System. Combined weather forecast information with hydrology information organically, The real-time forecasting operation principle is given according to the real-time forecasting operation method based on decision tree technology and predict its forecast error. Taking a Water Transfer Operation System as an illustration, demonstrates research results has theoretical as well as practical values for the full use of water resources. It is an effective way to improve the Inter-basin Water Transfer System operation level.(4) How the system worked reasonably, operated scientifically and managed effectively is an important and complexity task to guarantee its planned aim and obtain the maximum comprehensive benefit. Aim at the questions like lacking a uniform and efficient management system in Inter-basin Water Transfer Project in our country, study on management pattern and analyze benefit in different situations. Taking a Water Transfer Operation System as an illustration, recommended a coordinating committee management pattern using utility function of multi-objective evaluation model, and provide a lot of beneficial references and useful experience for management system reform and setting.Finally, a summary is given and some problems to be further studied are discussed.
