An improved diffusion model for supply chain emergency in uncertain environment

Emergencies will bring the great threat to the stability and coordination of supply chain, such as temporary interruption of raw materials supply, strong fluctuation of demand and distorted information transmission, which will lead to the breakdown of whole supply chain and threaten the survival of enterprises in supply chain. Based on the influence factors of emergency diffusion and supply chain structure in uncertain environment, this paper studies the diffusion effect of emergency and establishes an improved Bass diffusion model. On this basis, information diffusion simulation is carried out. Finally, management suggestions are proposed on supply chain emergency diffusion in uncertain environment.
