摘　　要：将再生水纳入供水体系是缓解水资源短缺问题的战略性举措,针对纳入再生水的多水源优化配置中存在的不确定性和稳定性问题,耦合蒙特卡罗模拟和区间两阶段鲁棒随机优化,构建多重不确定性条件下的多水源优化配置模型,有效处理供水和需水过程中以区间和概率分布形式表征的不确定性,同时权衡水资源配置中的可变随机值和追索成本,控制系统风险,得到不同情景下的水资源配置方案,将改进的模型应用到山西大水网的临汾盆地—晋城沁丹河流域供水区,综合分析不同情景下的区域用水效益和缺水损失,得到不同再生水利用率下的多水源联合配置方案,为决策者在不确定条件下考虑再生水利用的水资源优化配置方案提供了参考依据。Integrating reclaimed water into water supply system is a strategic measure to alleviate the problem of water resource shortage.Aiming at the uncertainty and stability existing in the optimal allocation of multiple water sources including reclaimed water,Monte Carlo simulation and interval two-stage robust stochastic optimization were coupled to build the optimal allocation model of multiple water sources under the condition of multiple uncertainties.The uncertainty represented by the form of interval and probability distribution in the process of water supply and water demand was effectively handled.The variable random value of water resources allocation and the recourse cost were balanced,and the system’s risk was controlled.The water resources allocation schemes were obtained under different scenarios.The improved model was applied to water supply area in Linfen Basin-Jincheng Qindan river watershed of Shanxi large water network.Based on the comprehensive analysis of regional water efficiency and water loss under different scenarios,the joint allocation scheme of multiple water sources under different utilization rates of reclaimed water was obtained,which provides a reference for decision makers to consider the optimal allocation scheme of reclaimed water under uncertain conditions.
