Research on Robustness of Emergency Transportation System of Materials Based on the Three-layer Interdependent Network

The ability to transport materials under emergency conditions is one of the important capabilities country respond crises. In order study material transportation system resist external damage, this paper builds a three-layer interdependent network model based on capacity-load analysis basic characteristics system, and conducts random attacks network, studies relationship between overall robustness flow . addition, three sub-networks studied, which provides theoretical basis for constructing reasonable robust system.
