Abstract
Resulting from the continuous increase in water demand, water resource is becoming an important issue in Taiwan, and the exploitative limitations because of the natural environment and difficulties in finding suitable dam sites make it even more complicated. To solve this problem, managing the available water more efficient may be the most feasible way by now. This study, hence, pursue a step forward to enhance the reservoir operation management. There are basically two approaches, i.e. simulation and optimization, to deduce the operation rules of reservoir. Recently optimization approach can be easily carried out because of the rapid progress in computer; consequently, the Fuzzy Stochastic Dynamic Programming, a sort of optimization method that fits in well with the real situation, is adopted in this study to build a reservoir operation model. It handles the decision-making problem in mult-purposes by fuzzy optimization theorem. To deal with the representative values for inflow and outflow, this study introduces the idea of Grey theorem. The Fuzzy theorem and Grey theorem are implanted with the optimization approach to construct the model of "Grey Fuzzy Stochastic Dynamic Programming". This model is applied to the Shi-Man Reservoir and the M-5 curves, the method employed now in the actual reservoir operation, is chosen as the comparison method. Under the criteria of shortage index and total shortage amount, both results of outflow simulation show that the "Grey Fuzzy Stochastic Dynamic Programming" performs better in long term reservoir operation than the M-5 curves.
