【摘要】：应急物资的采购和储备是应急管理的一项基础工作,但是由于面临不确定的需求,决策可能带来的供应不足和资源浪费风险非常大,探索提高决策质量效果的科学方法和机制,势在必行.本文将实物期权契约引入到由政府和供应商组成的非营利性供应链中,通过建立协调机制,提出了基于实物期权契约的应急物资采购模型,为政府确定合理的期权价格策略提供决策依据.通过实验仿真,对比分析了期权合约带来的政府成本和供应商收益变化,进一步分析了不同价格策略对供需双方的作用效果,以及应急条件下现货市场供应能力和突发灾害发生时间点对供应双方决策的影响.结果显示,通过参与期权合约,政府可以大幅度减小实物储备量,有效降低库存成本,供应商也可以获得更大的收益,带来整体效益增加1.43%的实际效果.
[Abstract]:The procurement and reserve of emergency materials is a basic work of emergency management, but due to the uncertain demand, the risk of insufficient supply and waste of resources may be very high. It is imperative to explore the scientific methods and mechanisms to improve the quality of decision-making. This paper introduces the real option contract into the non-profit supply chain composed of government and suppliers, and establishes coordination mechanism. This paper presents an emergency material procurement model based on real option contract, which provides the decision basis for the government to determine a reasonable option price strategy. This paper compares and analyzes the changes of government cost and supplier income brought by option contract, and further analyzes the effect of different price strategies on both supply and demand. And the impact of the spot market supply capacity and the time point of sudden disasters on the decision of both suppliers under emergency conditions. The results show that the government can greatly reduce the amount of real reserves by participating in the option contract. By reducing inventory cost effectively, suppliers can gain more income and increase the overall benefit by 1.43%.
