The rational allocation of constrained water resources under conditions of uncertainty holds significant importance for the formulation of effective economic s- trategies. This paper reformulates a two-stage stochastic programming model designed for agricultural irrigation systems into a two-stage stochastic variational inequality, subsequently solving it through a progressive hedging method. The experimental re- sults show that the algorithm can find a reasonable and stable optimal solution and the optimal objective function value efficiently.展开更多
