Background: In a short period of time after a disaster, there is a significant demand for emergency equipment, and the materials needed for rescue must be transported to the affected areas at specific times. Therefore, timely and reasonable allocation of limited resources to disaster-prone areas is critical. In such a situation, the locations of emergency distribution centers and routing are critical for the transfer of relief equipment and are the core of the decision to send emergency materials. On the one hand, it is necessary to place a certain number of distribution centers in suitable places for storing and transporting relief materials. On the other hand, it is necessary to dispatch appropriate equipment and plan their routes to deliver materials from distribution centers to disaster areas, which remains a challenge in the field of emergency logistics.
Aim: The purpose of this research is to minimize the access time to the affected areas and the number of unaided areas, as well as the distribution of aid in a critical situation after an unpredictable natural disaster, in such a way that the least amount of life and financial damage is received by the victims of the accident.
Methodology: This research is an applied research in terms of its purpose, and MATLAB software and NSGA-II algorithm were used to solve the problem. Conclusions: The number of damaged places that have not been helped can be minimized by reducing the risk and increasing the effectiveness of service delivery. But it should be noted that the effectiveness is affected by all the cost parameters and the most effective is the transportation cost and then the fixed cost. In such a way that the cost of transportation can greatly reduce the effectiveness. Therefore, in order to increase the effectiveness, the desired costs should be reduced as much as possible, which is possible by choosing the right path.
