Stackelberg game robust optimization model for water quality protection and water resource utilization and its application
The complex uncertainties of water resources systems bring challenges to reliable optimal allocation of water resources.In order to achieve a balance between water quality protection and water use efficiency,a stackel-berg game robust optimization model was established based on robust parameters that quantify the uncertainty of the water resources system,and the robust equivalent conversion method and the fuzzy satisfaction algorithm were used jointly to solve the problem.Taking the middle and lower reaches of the Hanjiang River basin as the research area,the results show that the equilibrium solution of the stackelberg game robust model is located obliquely above the op-timization solution of the traditional multi-objective model with a trend of increasing total sewage discharge and de-creasing economic benefits,and the optimization objectives of the equilibrium solution are inferior to the optimiza-tion;uncertainty affects the decision-making of the equilibrium solution range,and the equilibrium solution range is wider under high uncertainty,which can provide a basis for improving the adaptability of decision-making strate-gies under uncertainty.Compared with the single-objective water quality protection robust model and the economic development robust model,the stackelberg game robust model can provide a more balanced water resources alloca-tion plan.Sensitivity analysis of the model reveals the response pattern of the target layer to robust parameter chan-ges.The research provides an adaptive and robust decision-making method for water resource conflict management under uncertain scenarios.
