考虑协同创新的供应链多中断系统动力学建模及仿真

System dynamics modeling and simulation of collaborative innovationfor supply chain disruptions

受国际冲突、贸易环境、气候、重大疫情等因素影响,供应链中断事件频发。针对供应链产能中断和运输中断,引入协同创新,构建由供应商、制造商、零售商组成的3级供应链系统动力学模型,探究供应链多中断情景下协同创新对供应链整体利润变化趋势的影响。仿真结果表明,协同创新能有效提高供应链中断后的恢复能力、增强供应链韧性,选择不同的主体进行协同会产生不同的效果,但在不同中断情景下由供应商主导创新活动、零售商分担创新成本的应对效果更佳。

Affected by international conflicts,trade environment,climate,major epidemics,and other factors,supply chain disruptions occur frequently.Aiming at supply chain capacity and transportation disruption,collaborative innovation is introduced,and a three-level supply chain system dynamics model consisting of supplier,manufacturer,and retailer is constructed to explore the impact of collaborative innovation on the overall profit trend,average service level,and bullwhip effect of the supply chain under supply chain disruptions.The simulation results show that collaborative innovation can effectively improve and enhance the resilience of the supply chain.Different agents will produce different effects for collaboration,but under different disruption scenarios,it is more effective to have the suppliers leading the innovation activities and the retailers sharing the innovation costs.
