Complex Evolution Game and System Dynamics Simulation on the Impact of Coevolution on the Stability of the Fresh Agricultural Products Green Supply Chain

Although optimization of a fresh agricultural products supply chain has been widely studied, not much attention was paid to the impact of coevolution on the stability of such a supply chain, especially in the green development of such a supply chain. In this paper, based on the synergy theory and by considering the green development of the supply chain, with logistic model deduction of the trading volume of the supply chain as the system order parameter, system dynamics simulation is performed, showing the influence of the coevolution mechanism of various subsystems and the complex evolution game process on the stability of the supply chain. These results indicate that excessive coevolution among subsystems is not conducive to the supply chain when it enters a stable and orderly state. Only when the coevolution ability is controlled within a certain range can each subsystem achieve maximum profit. At the same time, the simulation results demonstrate the positive impact of coevolution on the stability of the supply chain. Sensitivity analysis shows that environmental factors such as the recycling rate of rotten products and the levels of government regulation and environmental ethics regulation have a positive impact on the stability of the supply chain, for which the larger the climate impact factor is, the less conducive it is to the stability. This research report provides some guidance for the sustainable development of the fresh agricultural products supply chain.
