Abstract: Logistics facilities in multi-level logistics distribution network may be disrupted in the case ofearthquake, epidemic and other factors. When a distribution center in the multi-level logistics distributionnetwork is interrupted because of an emergency event, the original network needs to be redesigned tomeet the demand of the customers. This paper aims to redesign a multi-level logistics distribution networkin the case of distribution center disruption. A mix-integer programming model is established, and tworules for the network redesign are proposed. The experimental results show that the proposed model cansolve this problem, and the effectiveness of the methods based on the greedy rule and the reschedulingrule is verified.

Key words: multi-vehicle distribution； multi-level logistics distribution network, mixed-integer program-ming； network redesign
