AbstractIgnoring the uncertainty as the main source of variability in reservoir operation leads to failure in water supply, especially at drought conditions. Several deterministic models have been developed for reservoir operation in such as conditions, i.e. Hedjing rule models. In this study, an explicit stochastic optimization model is developed to incorporate the uncertainty for optimal hedjing rules determination. The proposed methodology is based on the constraint state formulation which uses the first and second order moments of storage state variable as the constraint to incorporate the uncertainty in optimization. The proposed optimization model is solved using the Genetic Algorithms (GAs). As a result of using this model, an optimal reservoir operation rule at drought condition, and its long-term average net benefit as well as reservoir mean and standard deviation can be determined
