Location-routing decisions in an earthquake relief network

Abstract

In this paper, an integer mathematical model is developed in order to configure part of the earthquake relief network in Istanbul, Turkey. The aim of the mathematical model is to help decision makers decide on the locations of sub depots (distribution centers), as well as routing relief aid parcels from the main depot to the sub depots; and from the sub depots to the neighborhoods while minimizing the total distance of transportation and taking into consideration the sub depot and neighborhood coverage restrictions, and capacities. The mathematical model is implemented in a pilot area, Eyup, and solved optimally with LINGO 7.0 solver. The data related to the main depot, potential sub depot locations and capacities, and demands of neighborhoods are obtained from Eyup municipality in Istanbul.
