Considering the inevitability of natural or man-made disasters in the current world, unforeseen events management plays an important role in reducing human casualties and materialistic costs in the event of natural or man-made disasters.
Transfer points are points responsible for gathering and transfer of flow from request points to service-giving facilities. Transfer of flow from these points to service-giving centers is performed with a higher speed. One of the main applications of these points is transferring the injured people to hospitals; however, these points can be either used for transferring goods in addition to the injured people. Meanwhile, considering the special circumstances that are caused by the disasters, there is a possibility of disruption in sources considered in the planning. The sources can include facilities, roads, and hospitals.
The previous studies have not considered the issue of disruption in positioning the transfer points and most of them have focused on transferring the injured ones to hospitals. In the present thesis, by simultaneous consideration of preparedness and response phases, transmission of the injured ones and distribution of relief items in the areas of disaster by transfer points while considering disruption in the facilities are considered as a fundamental assumption. Given the humanitarian nature of the relief efforts and preference to transferring the injured victims to hospitals and sending relief supplies to areas over the costs of construction and operation, two dual objective models with the objective functions of minimizing the total time and total cost, and minimizing the maximum time and overall costs, respectively, are presented. The models are solved by Gams software with ε – constraint method, and the computational results obtained from solving them have been analyzed. Finally, case study was conducted on regions 6 and 7 of Tehran.
