应急物资储备方式选择与成本分摊问题

Research on Selecting Storage Manner and Cost Allocation for Emergency Materials

在假设单位时间内突发事件发生次数服从泊松分布的基础上,分析企业和政府分别储备应急物资时的成本。针对单位时间内发生多次突发事件的情况,假设应急物资需求量是在一定范围内的随机变量,建立了不同形式下的成本函数;在物资报废收益、物资动态更新费用、突发事件发生频率等变量变动的情况下寻找使应急物资存储成本节省的储备方式;利用合作博弈理论解决企业储备时政府和企业成本的分摊。

Under the assumption that the times of emergency conforms to Poisson distribution,we analyze the storage cost while government or enterprise storages the emergency materials respectively.Firstly,according to the case that emergency may occur many times in unit time,we establish different forms of cost functions supposing that emergency materials＇ demand is random variables in a certain range.Secondly,we find the best way making the storage cost of emergency materials smaller when scrapped income of unit material,dynamical update cost of unit materials and frequency of emergency are changing.Finally,we solve the cost allocation between government and enterprise using cooperative game theory when the enterprise storages the materials.
