Study on the Optimal Allocation of Water Resources in Major Basins of China Based on Intuitionistic Fuzzy Coalition Cooperative Game
The distribution of water resources in China is uneven,showing the characteristics of more in the south and less in the north.With the growth of population and the continuous development of social economy,the demand for water resources is increasing.In order to improve the comprehensive utilization efficiency of water resources,it is urgent to carry out cross-regional allocation of water resources to achieve secondary optimal allocation after the completion of the initial allocation.How to select the cooperation objects,how to balance fairness and efficiency,and how to share the cooperation benefits have become the core issues to be solved in water resources reallocation.This paper proposes the application of intuitionistic fuzzy coalition cooperative game to water resources optimization allocation problems.By constructing water resources optimization allocation models and cooperation benefit functions based on clear coalition cooperative game and fuzzy coalition cooperative game,and using methods such as intuitionistic fuzzy set,interval Choquet integral and continuous ordered weighted average operator,water resources optimization allocation model and cooperation benefit function based on intuitionistic fuzzy coalition cooperative game are derived.Optimal solutions are solved using intuitive fuzzy Shapley value.The Yangtze River basin in the southern region and the Yellow River,Hai River,Huai River basins in the northern region are selected as research objects.Industrial water is selected as allocation water,and return rate of industrial water is taken as the"priority principle"for water resources allocation.Compare and analyze the cooperation objects and benefit distribution of water resources allocation in major river basins under three different models.The results indicate that:①After completing the secondary allocation of water resources in each region,better cooperation benefits have been achieved compared to non-cooperation.②The benefits obtained by participating in intuitionistic fuzzy cooperative coalitions are all higher than those obtained by participating in fuzzy cooperative coalitions.③In intuitionistic fuzzy cooperative coalitions,the size of the coalitions should not be blindly pursued,but should be determined based on the actual situation of the region.The above research results indicate that the intuitionistic fuzzy coalition cooperative game provides a new solution for solving cross regional water resources allocation in river basins,which will provide a scientific decision-making basis for major river basins in China to carry out and optimize cross regional water resources allocation.
