A supply chain risk assessment model based on multistage influence diagram

Abstract

Supply chain system is a dynamic network system with fuzzy edge, and how to assess the risks of this system has become the bottleneck of enterprises management. In the light of the influence diagram theory, this paper builds a risk assessment model of supply chain from the topology layer and function layer. The model graphically describes the elements of risk assessment process and takes into account both the uncontrollable and the controllable factors in the supply chain risk. This paper can provide help for the supply chain risk management in strategic and tactical decision-making.
