Robustness Analysis of Cold-Chain Logistics Emergency Materials Storage and Transportation Network under Emergency Scenes

Abstract

In the process of dealing with all kinds of emergencies, such as natural disasters, it is particularly important for emergency materials to reach the disaster areas in time and in full.  During the COVID-19 epidemic, designated emergency material transfer points had been set up in Wuhan City, Hubei Province or Xi'an City and Shaanxi Province to help get through the transportation channels and ensure the social life and material supply in the affected areas. Under this background, cold-chain logistics, as one of the important means to protect people's livelihood materials, has received extensive attention. In this paper, Hubei Province where emergency materials transit points had been set up during the COVID-19 epidemic is taken as the example. The robust optimization analysis is made for the emergency transit cold storage. By collecting the location data of retail nodes in Hubei Province, the Hubei emergency material transportation network is depicted, and its network characteristics and cascading failure robustness are analyzed to summarize the experience and practice of regional disaster emergency materials support in China, and provide some reference for improving various emergency response mechanisms.
