Abstract: To solve the emergency logistics problem in large-scale disaster relief operations with the main goal of minimizing the total number of fatalities, two mixed-integer linear programming models were developed to design the locations of logistics centers and vehicle routing based on the decision mechanism of relief distribution. The location problem and the vehicle routing problem were separately modeled and solved for the control of model complexity. An illustrative example is presented to demonstrate the applicability of the proposed method.
