The Risk Elasticity Measure Index Exploration of Supply Chain and Mechanism Research

Abstract

The modern supply chain were more vulnerable to risk, supply chain risk mainly comes from many aspects of the internal and external environment, the supply chain industry products background, upstream and downstream supply chain relationship, decision support. The study found that the need to establish information sharing mechanism, multi- level supply chain defense system, the principal-agent mechanism and supply chain emergency mechanism to build flexi- ble supply chain, in order to achieve the purpose of supply chain risk management. In this paper, the establishment of a complete supply chain model with variable structure, through the simulation method for quantitative observation of sup- ply chain flexibility curve, and abstract to describe the elastic curve of a set of parameters; after the design of simulation experiment to observe the different supply chain structure parameters (inventory level, supply chain, supplier selection for number of sources) influence supply chain resilience curve. At the same time to observe and analyze the supply chain by the recovery phenomena rules in the process of risk impact and elastic. And finally the quantitative impact evaluation of supply chain structure parameters on the supply chain flexibility.
