Vulnerability Assessment of Emergency Logistics System Based on Linguistic Variables

Tong-tong Nie, Xian-long Zhang

Abstract


“Vulnerability” is one of research hotspots in the domain of emergency logistics system, and the term is now a central concept in a variety of research contexts such as natural hazards, computer network security, and sustainable development. Based on the analysis of the evolution of vulnerability concept and research content, this paper aims to find a generally applicable vulnerability conceptual model and assessment methods of emergency logistics system which are key factors to determine the development of vulnerability science. In this paper ,vulnerability index system in the emergency logistics system is firstly constructed, on the basis of which the direct expert linguistic evaluation value is converted into triangular fuzzy number to establish the evaluation model based on gray correlation method and conclude the decision steps and finally a practical example is used to illustrate the validity of this method.

Keywords


emergency logistics system, vulnerability assessment, linguistics variables, vulnerability conceptual model, triangle fuzzy number.
