Abstract: Based on the information entropy theory and fuzzy matter-element theory,an information entropy fuzzy matter-element model for normal high water level of reservoirs is described.The optimum normal water level is decided by the Hamming approach degrees of each plan.The natural information of proposed schemes are fully considered and individual subjective factors are avoided in the decision process of weights of evaluation factors such as information entropy weight and expert weight.Results of practical examples show that this method is effective and feasible.
