Stochastic Fuzzy Dynamic Programming for Multi-dimensional and Multi-objective Complex Agricultural Water Resources System and Its Application

基于多目标模糊优选动态规划理论,结合复杂农业水资源系统决策的复杂性、多目标性以及水文过程的随机性和具有时序性的特点,提出了随机多维模糊优选动态规划模型,并根据所研究问题的性质,给出两种随机多维问题的解法:随机多维决策相对优属度最大法和阶段模糊优选法。将该理论及方法应用于作物非充分灌溉制度的设计,实例证明了解法的可行性和模型的实用性。

Based on engineeringfuzzy set theory,this paper presents a stochastic multi-dimensional and multi-objective fuzzy dynamic programming,it can be used in decision making among complex agricultural water resources system,which characterized by random inputs.Two different methods are given,one is named maximum of relative membership and the other is staged fuzzy optimization theory.They are explained in detailand can be used under different conditions.At the end this model and its methods areused for inadequate irrigation schedule programming when the rainfall is stochastic,the case study proves that the model and method are reliable.
