Location problem of shelters and telecom-relief centers considering uncertainty in the disaster time: A Case Study of flood disaster in region #3 of Tehran

One of the most important issues that should be considered in the disaster management is temporary settlement of injured population, supplying relief commodities, designing an appropriate communication infrastructure for communication in the disaster time. For this purpose, in this paper a model has been proposed for locating shelters, warehouses of relief commodities, and also telecom towers, wherease warehouses of relief‌ commodities and telecom towers have been considered as the telecom-relief center for reducing costs and improving services. The backup warehouses are also used to improve the reliability in disaster management in the model. The problem has been modeled as a nonlinear and bi-objective model, while for solving the normalization method and and he linearization approach have been applied. With respect to significance of unstable conditions and dynamic enviorement in natural disasters, the model has been considered under uncertainty and method possibilistic programming approach is used to cope with this issue. The proposed model is implemented in the flood disaster case study of Tehran and the obtained results show that the optimal location of the facility can help the decision makers of disaster management in this area about increase service during disaster.
