为提高社会化应急物资联合储备模式的适用性和拓展性、降低政府和制造商的储备风险,引入原材料供应商构建数量柔性契约下政府主导的Stackelberg政企三级联合储备模型.在该模型中,政府和制造商共同储备应急物资的实物,而供应商则负责储备生产应急物资的原材料.使用博弈论中逆序求解法分析政企三方各自的最优储备量,均衡状态下的期望利润和期望成本;并与政府单独储备模式进行对比,以评估政企三级供应链的优势;最后,通过数值模拟和敏感性分析的方法验证结论.研究结果表明:特定的市场条件下,政企三级联合储备模式不仅能够提高整体应急物资储备量,也可降低政府储存风险,提高企业利润,还可强化应急物资储备系统的结构和效能.
Research on joint reserve decision-making of government and enterprises under quantity flexibility contract
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.
