Research on Fuzzy Optimization of Compensation Benefit Scheme of Cascade Reservoirs in the Main Stream of Yellow River

Based on fuzzy optimization theory,the paper proposes an optimization model of compensation benefit of cascade reservoirs in the main stream of Yellow River.With this model to optimize the six compensation benefit schemes,then to compare the results with AHP and catastrophe evaluation method.The results show that fuzzy optimization can be used in different scheme optimization and in evaluation for different schemes.Consequently,the optimation result is more reasonable and more practical.
