Abstract—To find theindustry characteristics of emergency in supply chain and to solve the problemof recognition about that. The paper established causation factor indexessystem of emergency in supply chain based on systems analytical method, and atthe same time, put forward a industry characteristics recognition model foremergency supply chain based on fuzzy clustering utilizing fuzzy similarity relation,fuzzy equivalence relation and fuzzy equivalence matrix. An empirical analysisis carried out to find the characteristics of IT, chemical, auto,transportation and other 6 industries under supply chain emergency, whichindicates that IT, medicine and chemical, transportation, agriculture, steel havesimilar characteristics of supply chain emergency respectively, and theestablished model is applicable for solving the problem.
