Allocation of water use is one of the most important challenges of water resources management that needs to evaluate water reuse options, especially in areas with limited water resources, arid climate, increasing water demand due to population growth. In this study, the modified TODIM method (Multi-Criteria Decision-Making in Portuguese with considering the risk preferences of decision makers) that can be used with goal programming (GP) by considering Leopold matrix outputs in order to preform Environmental Impact Assessment (EIA). The present study is aimed at optimally allocate water reuse to multiple stakeholders in Najafabad, Isfahan, Iran. The results showed that the numerical model developed with an integration of optimization and quantitative evaluation can be considered as a useful tool to develop feasible guidelines for adapting the requirements of different stakeholders for optimized allocation of recycled water.

用水分配是水资源管理最重要的挑战之一，需要评估水的再利用方案，特别是在水资源有限，气候干旱，人口增长导致用水需求增加的地区。在这项研究中，通过考虑利奥波德矩阵的输出，可以与目标规划（GP）一起使用改进的TODIM方法（葡萄牙语的多标准决策方法，考虑决策者的风险偏好），以进行环境影响评估（EIA） ）。本研究旨在最佳地将水的再利用分配给伊朗伊斯法罕的纳杰法巴德的多个利益相关方。
