     real-time hydropower reservoir operation is a continuous decision-making process of determining the water level of a reservoir or the volume of water released from it. the hydropower operation is usually based on operating policies and rules defined and decided upon in strategic planning. this paper presents a fuzzy rule-based model for the operation of hydropower reservoirs. the proposed fuzzy rule-based model presents a set of suitable operating rules for release from the reservoir based on ideal or target storage levels. the model operates on an ‘if-then’ principle, in which the ‘if’ is a vector of fuzzy premises and the ‘then’ is a vector of fuzzy consequences. in this paper, reservoir storage, inflow, and period are used as premises and the release as the consequence. the steps involved in the development of the model include, construction of membership functions for the inflow, storage and the release, formulation of fuzzy rules, implication, aggregation and defuzzification. the required knowledge bases for the formulation of the fuzzy rules is obtained form a stochastic dynamic programming (sdp) model with a steady state policy. the proposed model is applied to the hydropower operation of “dez” reservoir in iran and the results are presented and compared with those of the sdp model. the results indicate the ability of the method to solve hydropower reservoir operation problems.
