An Intraseasonal Dynamic Optimization Model to Allocate Irrigation Water between Crops
提出一个动态规划模型，在随机天气模式下将季内15次灌溉分配给玉米和高粱，并允许干旱期暂时或永久放弃一种作物，为灌溉管理提供简化策略。
Abstract A dynamic programming model that allocates irrigations among competing crops, while allowing for stochastic weather patterns and temporary or permanent abandonment of one crop in dry periods, is presented. Fifteen intraseasonal irrigations are allocated between corn and sorghum fields on the southern Texas High Plains. Broad rules of thumb implied by the results suggest irrigating the driest field in any stage unless soil water is close to field capacity on both fields or below wilting point on corn. A crop simulation model is used to reduce the complicated decision rules into simpler strategies with similar net returns.
