Abstract: In this study we address selecting capacitated shelter locations in preparation for disasters under demand uncertainty and random transportation network disruptions by an inequity-averse approach. We develop a 2-stage stochastic programming model to minimize a linear combination of efficiency and inequity measures. Moreover, a service level is imposed by a chance constraint. We approach the model in terms of ex ante and ex post approaches. We develop a tailored genetic algorithm (GA) to solve this problem for large real-life and benchmark instances. Our computational results show that the GA outperforms Cplex in terms of run time and solution quality. We derive insights from a case involving an earthquake-prone district of Istanbul.
