Emergency logistic system is quite important for natural disaster recue and other unexpected incidents treatment. At present, most relative modelling and analyzing research on logistic network invulnerability is based on a single network, and does not take the interaction between networks into account. This paper proposes the complex multi-layer logistic model consists of command control network, space communication network and physical transportation network based on interdependent network theory. The result of network invulnerability research shows that the three-layer interdependent network model is more precisely and conform to the actual situation of emergency logistic system operation. Moreover, the invulnerability evaluation method proposed in this paper is more accurate and detailed than the traditional method. This conclusion can provide references for the designing of emergency logistics system with better invulnerability and applied to other areas research.
