Optimal Model of Reservoir Flood Operation Considering Objective and Subjective Weight and Its Application

According to the objective weigh provided by fuzzy iteration methodology, the paper presents the concept of weight tradeoff coefficient, combining subjective and objective weight together. Since the method takes into account, in the meantime, the objective intent of decision-maker and the natural property of alternative, the weight and relative member-ship degree are directly obtained from the recommended alternatives supplied by decision makers, the difficulty of weights determination can be avoided and the ranking of alternative is more feasible and reasonable.
