【摘要】：针对应急物资的采购和生产能力储备问题,本文设计了一个基于能力期权契约的双源应急物资采购模型.在存在一个能力有限的现货市场的前提下,政府作为唯一的采购方,期初向一个合约供应商采购实物储备量,并向供应商购买一定量的生产能力期权,一旦在期权执行期内有应急物资需求发生,可立即将储备的生产能力转化为实物产量.通过推导和算例模拟证明,这样的采购机制可以在有效减少政府实物储备量的同时,大大降低了缺货风险,同时也合理补偿了灾后供应商因被安排突击生产而增加的成本,有效实现了应急物资供应链的采购协调,政府和供应商企业双方达到了双赢的效果.
[Abstract]:In order to solve the problem of emergency material purchasing and production capacity reserve, this paper designs a dual source emergency material purchasing model based on capability option contract, under the premise of a spot market with limited capacity. The government, as the only buyer, buys real reserves from a contract supplier at the beginning of the period, and buys a certain amount of capacity options from the supplier. Once there is a need for emergency materials during the option execution period. The production capacity of the reserve can be immediately converted into physical output. Through the derivation and numerical simulation, it is proved that the procurement mechanism can effectively reduce the amount of government physical reserves, and greatly reduce the risk of stock shortage. At the same time, it also reasonably compensates the cost increase caused by the supplier being arranged to surprise production after the disaster, realizes the procurement coordination of the emergency material supply chain effectively, and both the government and the supplier enterprise achieve the win-win effect.
