双区间规划在单一作物水资源优化配置中的应用

Application of Dual Interval Programming in Water Resources Optimal Allocation for Single Crop

干旱的内陆地区,降雨稀少,水资源极度贫乏,进行农作物的水资源优化配置成为必然。在运用区间规划进行水资源优化配置过程中,很多的模型参数因为高度不确定性或数据资料短缺导致参数区间的上下限不能确定的情况很多。本文试引入改进后的双区间规划,用水分生产函数Jensen模型并以经济效益最大为目标函数对民勤县的春小麦进行了生育期内水资源的优化配置,将有限的水资源总量分配到作物的不同生育阶段,并对规划结果进行了概率分析。

In arid inland with rare rainfall,water resources are extremely scarce,so water resources optimal allocation becomes inevitable.When applying interval programming to water resources optimal allocation,the lower and upper boundaries of many parameters in the model cannot be determined because of the existing highly uncertain information or lacking of data.This paper targets the maximum economic benefit and introduces the improved dual interval concept into Jensen model to optimize water resources allocation in growth periods of spring wheat in Min Qin County.The model can distribute limited water resources to different growth periods of spring wheat.At last,the paper gives a probabilistic analysis of the optimization result.
