Description:
In this study, a type-2 fuzzy based interval-stochastic risk management programming (TISRM) method is proposed for optimal irrigation water resources allocation associated with multiple uncertainties expressed as interval numbers, probability distributions, and type-2 fuzzy sets. TISRM can also reflect authorities’ attitudes towards system risk using a financial risk management measure by controlling the variability of the recourse cost. The developed method is applied to irrigation water resources allocation for the Zhangweinan River Basin in China. Solutions of irrigation water allocation under different probability distributions and confidence levels are generated. Results reveal that system benefit and satisfaction degree would decrease with the raised λ levels; the CVaR values would change with the increment of λ and β levels as well as the varied cases; the irrigation targets of all crops in all subareas are reach their lower bounds; the irrigation deficits w...
