RESUMO

The operation rules constitute one of the main elements in the planning and management of water resources systems. The application of the standard operational rules can be present unsatisfactory in periods of drought or imminent drought. These rules can result in periods with deficits of great magnitude, leading the system to a highly vulnerable situation. Many times, this can be avoided or minimized using hedging operation rules that admit deficits in phases of flood, drought or in both phases of operation. Therefore, the storage in the reservoir is increased to prevent deficits of great magnitude that can occur in the future. In this work a computational routine to attain the operational rules of the reservoirs systems was developed, considering a new approach of hedging rule. The operational strategies of the Cantareira system were obtained through the usage of genetic algorithms (GAs). The results demonstrated that the use of optimization techniques, as the AGs, is an important tool to assist in the decision making. Moreover, the hedging rules were suitable in the prevention of deficits of great magnitude that can occur in the future
