摘要：An inexact two-stage stochastic programing model was applied to sustainable utilization of water resource under uncertainty in Dalian city. The developed model, integrated the two-stage stochastic programing and inexact optimization, could deal with uncertain problems expressed as probability distributions and discrete intervals. After formulating the model, a hypothetical case based on the comprehensive planning of sustainable utilization of water resource in Dalian city was employed for demonstrating its application in the three different planning year, which was 2015, 2020, 2030. The optimal allocation of water resource with maximized system benefit among different users had been obtained. The result indicated that different water allocation schemes and water deficits with varying net system benefits would be hold in response to different streamflow levels. In a word, The ITSP model provided significant decision support that adjusted to the existing schemes of water allocation within a complex water resource system under uncertainty for water managers.
