Abstract

This Research Project is devoted to study a relief distribution problem in disaster situations under uncertainty. The novelty of this proposal rely on the development of a new optimization model to prioritize the relief assistance of the affected areas according to socioeconomic criteria, such as human development indexes, housing conditions, and so forth. In addition, as unsolicited donations may disrupt the post-disaster relief operations, we will include in the model the so-called material convergence constraints, so as to consider only the flow and distribution of solicited donations. The uncertainties will be represented by random variables within symmetric intervals and optimized from a worst-case robust optimization perspective. To solve practical instances of the proposed model, we will devise solution methods based on decomposition and heuristics. Both model and solution methods will be analyzed based on real instances from recent Brazilian disasters.
