Abstract: For the sake of improving the relief supplies support ability, optimization of relief supplies reserve bases network design was studied. A LIP model, considering disruption scenarios, fortification, capacity constraints and purchase discount, was built for relief supplies reserve bases on the basis of traditional RFLP and LIP researches. A NSGA-II based on niche technique was proposed to solve the model. A numerical example of relief supplies reserve bases construction for earthquake disaster indicates that a Pareto front solution set can be obtained solving the model by designed algorithm, from which the decision-makers may choose optimal decision schemes according to the actual needs.
