In this study, the dynamic effects of new product supply chain cooperation behavior on optimal government subsidies and supply chain decision-making are studied by establishing a nonlinear discrete inventory decision system; In this system, the government subsidizes authorized remanufacturers to promote remanufacturing, and cooperative behavior exists in the supply chain of new products. The research method is modeling and simulation of a supply chain system based on nonlinear system dynamics theory. The complexity analysis includes the stability analysis of the decision system, the path of the system into chaos, the change of entropy of the system and the performance in chaos system. Our findings indicate that the optimal government subsidy in the cooperative model is lower than that in the non-cooperative model. Consumer surplus is the main reason for the subsidy difference between the two models. In comparison with the cooperative supply chain, the stability of the non-cooperative supply chain is more easily affected by government subsidies. Further, the market is more likely to enter chaos due to improper adjustment of the new products' inventory with cooperative behavior in the supply chain of new products. When the system enters chaos, the new product supply chain's profit in the cooperative system is more likely to be far lower than the equilibrium profit. This study provides a theoretical reference for supply chain inventory management and government subsidy remanufacturer decision-making from the perspective of dynamic systems science.
本研究通过建立非线性离散库存决策系统，研究了新产品供应链合作行为对最优政府补贴和供应链决策的动态影响；在该系统中，政府补贴授权再制造商以促进再制造，并且新产品供应链中存在合作行为。研究方法是基于非线性系统动力学理论对供应链系统进行建模和仿真。复杂性分析包括决策系统的稳定性分析、系统进入混沌的路径、系统熵的变化以及混沌系统中的性能。我们的研究结果表明，合作模型中的最优政府补贴低于非合作模型。消费者剩余是两个模型之间补贴差异的主要原因。与合作供应链相比，非合作供应链的稳定性更容易受到政府补贴的影响。此外，由于供应链中新产品的库存存在合作行为，市场更有可能因新产品库存的不当调整而进入混沌状态。当系统进入混沌状态时，合作系统中新产品供应链的利润更有可能远远低于均衡利润。本研究从动态系统科学的角度为供应链库存管理和政府补贴再制造商决策提供了理论参考。
