A Two-Stage Stochastic Programming Model for Pre-positioning of Relief Supplies

Abstract

Pre-positioning and distribution of emergency supplies are important activities in the preparedness and response stages for disasters. The goal of this paper is to address the joint decision-making of pre-positioning and distribution of relief supplies under uncertain environment. A two-stage stochastic programming model with the objective of the minimizing total cost is formulated and the uncertainties of disasters are taken into account. A case study focusing on addressing hurricane threats in the Gulf Coast area of the US is conducted to illustrated the application of the proposed model. The results analysis provides managerial insights for relief agencies.
