Operations planning via stochastic programming and robust optimization


In this research project, we will study two operations planning problems that arise in different contexts: (i) the pump scheduling problem and (ii) the location-distribution problem in disaster situations. These two problems will be treated under the stochastic programming and the robust optimization viewpoints, as diverse input data are uncertainty by nature. The main goals of this project involve the study and the contextualization of the problems, the formulation of mathematical models, the design of solution methods, the computational issue, and the analysis of the results. The practical contribution of this project is the developing of the mathematical models to support the decision making. It is worthy of mentioning that the quantitative approach for the operations planning in disaster situations is practically inexistent in the national research. The theoretical contribution is the study of two different methodologies to deal with uncertainty, especially because they are not commonly used by Brazilian researchers. The results of this project will be reported in scientific conferences and submitted in national and international specialized journals. (AU)
