MODELING AND SIMULATION FOR MILITARY SUPPLY CHAIN RISK EVOLUTION BASED ON INFORMATION ENTROPY

Abstract. Military supply chain risk is an important index in measuring the reliability of military logistics equipment support. It has the characteristics of dynamic development, and how to conduct profound research on the development and evolution process has important practical significance. On the basis of defining system elements, this paper firstly constructed a system dynamics model of risk evolution by using risk evolution system flow diagram of military supply chain, then determined the relevant model parameters through the method of information entropy. Finally, by using the simulation method, this paper studied the impact of impulse mutation, risk tolerance and risk response ability on the risk evolution process. The results show that improving the ability of risk tolerance and risk response plays an important role in effectively controlling of military supply chain risk.
