To improve the applicability and scalability of the joint reserve model for social emergency supplies,and reduce the reserve risks of the government and manufacturers,raw material suppliers were used to propose a government-led Stackelberg three-tier joint reserve model of government and enterprises under a quantity flexibility contract.In this model,the government and manufacturer engaged in joint a stockpile of physical emergency supplies,while the suppliers were responsible for stockpiling raw materials for the production of emergency supplies.The inverse-order solution method in game theory was used to analyze the optimal reserve quantity of the three parties to balance the expected profit and cost.Moreover,the advantages of the proposed three-tier supply chain model involving government and enterprises were evaluated.Finally,the model performance was validated by numerical simulation and sensitivity analysis.The results demonstrated that the three-tier joint government-enterprise stockpile model not only improved the overall emergency stockpile volume under specific market conditions but also reduced the government's storage risk.Furthermore,it can enhance the profitability of high-performing enterprises and reinforce the structure and efficacy of the emergency stockpile system.
