基于捕食者—猎物模型的突发事件下供应链稳定性研究
A Study of the Stability of Supply Chain with Predator-Prey Model
摘要
Abstract
Stability of the supply chain has become an important research area in supply chain. To study the interactive mechanism between disruption and supply chain, a Predator-Prey Model of disruption and supply chain is built based on supply chain resilience coefficient and disruption interference coefficient, representing the two states of disruptions and supply chain. Then the equilibrium points are found and interdependent correlation of disruption and supply chain is analyzed, and the stability of supply chain under disruption simulated by Matlab. The results show that, in order to ensure the stability of the supply chain when the equilibrium point P4 is reached, the resilience coefficient of the supply chain should be σ1>1 and approaching 2, and the disturbance coefficient of the disruption should be σ2>1 and gradually approaching 1. When the equilibrium point P2 is reached, the resilience coefficient of the supply chain should be σ1>0 and approaching 2, and the disturbance coefficient of the disruption should be 0<σ2<1 and gradually approaching 0. The model is effective to formulate the interdependent correlation between disruption and the stability of supply chain. The exploration is meaningful to enrich the modeling methodology of supply chain disruption, and it is also significant to prevent and handle the disruption effectively.关键词
