Abstract

In this research project, we will study three operations planning problems that arise in the humanitarian logistics context: (i) a dynamic network-flow problem in which the uncertainty regarding the victims' needs is modeled according to the robust optimization perspective; (ii) a location-distribution problem with fleet sizing decisions and deprivation costs; and (iii) a supply chain design problem. The proposed problems involve the treatment of diverse uncertainty parameters, such as demand, supply, costs, among others, which will be modeled via stochastic programming and/or robust optimization. The main motivation in proposing models and solution methods for these specific problems relies on the lack of scientific investigation about them and on the computational difficulty for solving practical instances. The objectives of this project involve contextualizing the problems, formulating the corresponding optimization models, solving them, and analyzing the numerical results from the disaster management viewpoint. The results of this project will be disseminated in scientific conferences and submitted to specialized journals. (AU)
