multi reservoir optimal operation using shuffled complex evolution (sce) algorithm (case study: karkheh basin)

in recent decades, evolutionary algorithms have been applied successfully in various water resource engineering and management issue especially in optimal operation of reservoirs. in this paper, a model based on shuffled complex evolution (sce) algorithm has been developed for modeling optimal operation of complex multi reservoir system of karkheh basin. the system includes 4 different agricultural irrigation demands allocation with environmental prioritize in both short and long-term approach. in this study, development, increment of performance and algorithm’s resistance which are the main cause of having perfect mechanism of rullet-wheel and established preparation in the programming’s structure.  first, the accuracy of the developed model was evaluated by a number of standard functions. the results indicate good performance of the developed model. next the developed model was used for solving complex multi-reservoir system operation karkheh basin. results of model was evaluated by some statistical criteria and compared with the ga standard results. results show high performance and sce algorithm fitness to optimal operation of reservoirs.
