Abstract

Humanitarian logistics remain a challenging area of application for operations research. In relief distribution, the main goal is to deliver all the supplies to those that are in need in the fastest way possible. In this paper, we present different optimization solutions for relief distribution. We present a formalization of the three main problems in the humanitarian logistics aspect of relief distribution. We identify the optimal location of the distribution centers. We match the number of supplies to the number of demands for each distribution center based on the distribution of demands. We provide the assignment of tasks to delivery fleet according to the location and the road network of the region. For each delivery truck, we provide an optimal sequence of visits to pre-assigned distribution centers.
