Optimal Utilization Simulation and Decision Making on Water Resources System

According to system optimization theory, a multi-objective optimal allocation model of water resources system is established. Based on the maximal factor sensitivity analysis, the water allocation system with multi-constraint conditions is assessed. At the same time the numerical Solutions and program for the model which uses the minimum of the weight coefficient fluctuation to measure the influence degree of decision is developed. Then the optimal model of water resources system is used at the South-North Water Diversion Project region. Based on the weight coefficient sensitivity analysis, the model's practical suitability is considered. The study provides important reference to improve resources utilization efficiency and supply reliability. The method overcomes the disagreement disadvantage when transforming multi-object to single object during the process of solving the model. It is practical for water resources system assessment.
