Multimodal hub-spoke emergency logistics network design

An emergency logistics system is an important part of a social service system to provide emergency services. This paper designs a multimodal hub-spoke emergency logistics network, a mixed integer mathematic model is proposed to solve hub location problem and spoke allocation problem. Tabu Search algorithm is adopted. The mathematical model proposed in this paper shows a good overall performance in minimizing total cost and time dissatisfaction degrees of demand nodes through simulation verification.
