In the traditional reservoir operation system, in general, we use the rule curve as a method of operation, and the reservoir rule curve is the result of system simulation method. Due to the regular and simple rule curve operation unable to satisfy the actual demand effectively. In order to improve the defect, there are many system planning theories and optimum seeking methods to find the optimum operation strategies. The reservoir operators are uncomfortable with the complicated optimum operation strategies. In this article the fuzzy inference model is used to establish a simple and effective operation rule for the reservoir operator.
