摘　　要：假设需求量是当前库存水平的线性函数,建立了一带有通货膨胀的易腐库存模型,以系统平均总利润为目 标函数,找出了通货膨胀条件下库存系统的优化策略．并分析了通货膨胀率和各系统参数对最优订购量和目标函数 的灵敏度,最后将本模型与无通货膨胀情形下的库存模型作了比较,得出了一些有用结论,这将对企业的管理与决 策起指导作用．The paper builds a perishable inventory model based on stock dependent selling rate and inflation. We find optimization policies of inventory system under the condition of inflation by the total profit per unit time. The sensitivity of inflation and system parameter on optimal order quantity and objection function is reported. Many useful conclusions are achieved by comparing inventory model with inflation and without inflation, which is instuetive to the management and decision of enterprises.
