Abstract: A generalized decision support system (DSS) is presented for developing optimal operation policies for multi-purpose reservoirs. The model is designed for single reservoirs, although is can include a downstream afterbay. The DSS uses two primary models in the model base, a simulation model and a dynamic programming optimization model. Both models are based upon mass balance. The models have been designed to be as general as possible such that the user can describe varying physical or operational constraints and select operational objectives without altering the coding of the models. The selection of whether to use the simulation model or optimization model or both is at the discretion of the user. The inputs for the models are handled through a database where data entry forms and error checking are employed to assist the user. The results are displayed through various graphical display options. The entire system uses a graphical user interface with full menu capabilities. The system is implemented on a UNIX based engineering workstation.
