Study of the Influencing Factors of Emergency Logistics Based on DEMATEL Method

The duty of emergency logistics is to meet the demand of emergency material within the shortest possible time, the simplest process and the most efficient way. According to the statistical study of the relevant literature about emergency logistics, this paper, by using Bibliometrics method, screens out seven relevant factors which affect the emergency logistics. We use DEMATEL (decision making trial and evaluation laboratory) method to analyze cause and effect relation among these related factors, classify and sort those factor sets according to the quantitative results, and find out the key factors which affect emergency logistics, including distribution of reserve place (the distance between a saving point and emergency point), the reserve number of emergency materials, the transit time of emergency materials, the demand of emergency materials, the degree/grade of emergency incident. We expect to provide a scientific basis for emergency logistics management decisions.
