Research on characteristics of emergency logistics system based on interdependent network

In the modern security system, material support in emergency is an important part. In order to ensure the supply of necessary living materials and proprietary materials in wartime, major natural disasters and emergency epidemics, all countries have introduced corresponding measures. Emergency logistics system is a necessary condition to ensure the smooth and timely distribution of emergency supplies. This paper applies the complex network theory to study the main statistical characteristics of the three-layer emergency logistics system considering the material needs, material manufacturer and raw material resource supplier, which can provide a reference for optimizing the resource allocation and anti destruction ability of the emergency logistics system.
