Logistic network design for post-earthquake planning: A case study for ümraniye district under different earthquake scenarios

In this study, a logistic network design for post-earthquake planning was developed. The purpose of this design is to develop a plan that enables earthquake survivors to access to basic humanitarian needs in the shortest time. In this direction, humanitarian aid and need scores were calculated for each neighborhood in a selected region, using the humanitarian aid and need scores emergency material distribution center locations were defined and distribution centers to which each neighborhood will be connected were identified. An integrated two-stage model for logistic network design optimization is proposed. In the first stage, using Analytical Hierarchy Process (AHP), humanitarian aid and need scores of the neighborhoods, each of which is a candidate for a potential distribution center, were determined. In the next stage, with the help of humanitarian aid and need score weighted and distance minimization aiming p-median model, the neighborhoods in which the distribution centers should be located as well as the distribution centers which other neighborhoods should be connected to, were identified. The proposed model was applied to the problem of establishing humanitarian aid distribution centers in the post-earthquake period for the ümraniye district of Istanbul province, and the model was reconstructed for different earthquake scenarios
