Disasters affect the normality of affected region, causing damage and loss throughout the region's social and economic system. Humanitarian logistics operations seek to attend as soon as possible the required demand, with the main objective of saving the largest number of people. The aim of this study is to present a mathematical and computational model to support humanitarian operations in disaster events with emphasis on procurement function of supplies. Suppliers were selected with the possibility to deliver the items in short time, using networks flow model adapted, we used techniques of simulation and optimization. It was applied to the proposed model in scenario of adverse event occurred in the state of Santa Catarina. The result of the network flow problem, it was found that the product condition be as fast as possible on demand site was satisfied and we used the capacity of the suppliers in the most nearby dates.Downloads
