عنوان مقاله [English]
In this paper, a fuzzy optimization model, including the location of the tank and the wastewater treatment plant and wastewater allocation to agricultural areas for network design is presented. Firstly to determine the strategic decisions to locate and tactical allocation decisions for certain modes, the base model proposed then the model has been developed with regarding the uncertainties in the parameters using fuzzy approach. In addition, this paper has proposed a new approach according to using of wastewater in agriculture to increase crop health and reducing microbial contamination, with considering the different quality of effluent. Finally, a case study in Megacity of Tehran for model validation is applied with helping Agriculture Organization and Tehran Regional Water Company and, also, sensitivity analyzes are conducted. The results shown that the proposed model can help decision-makers to manage the water and sewage considering the consideration of proposed model and the contribuionts of that.
