With the improvement of people's understanding of disaster relief, emergency logistics has become an important guarantee to improve the efficiency of relief and safeguard the safety of people's lives and property in recent years. In this paper, the research theories, methods and models of emergency logistics are classified and sorted out, and different problems such as Location Allocation Problem, Vehicle Routing Problem, Location-Routing Problem are classified and discussed. Under the condition that most of the existing researches mainly focus on response cost and response time, this paper argues that the primary purpose of emergency logistics should be to reduce the loss of people's lives and property. Based on this, an extension study on emergency logistics is proposed to provide ideas for further research in related fields. Keywords-emergency logisticst; disaster relief; methods and models3rd
