Abstract

Under the condition that the demand for emergency materials is uncertain after the occurrence of an emergency, this paper considers the minimum time and cost of emergency rescue at the same time, studies the location problem of pre disaster emergency materials storage. The box uncertainty set is used to describe the uncertainty of demand, and a robust optimization model with capacity constraints is established. Based on Bertsimas and Sim robust optimization methods, the nonlinear robust optimization model is transformed into a robust corresponding model by introducing auxiliary variables and dual transformation. We use ε constraint method to transform the multi-objective problem into the single objective problem. An immune algorithm is designed to solve the problem. The feasibility of the model and algorithm is verified by computational experiments. The research shows that the robust optimization model has good robustness and can better resist the risk induced by uncertainty. Decision makers should determine the emergency rescue time constraint according to financial level and expected response level; evaluate the risk status, weigh the relationship between reliability and emergency rescue cost, and determine the robust uncertainty parameter for scientific site selection.
