通胀环境下短缺依赖时间的订货模型

EOQ model with linear time varying demand under inflation environment

文章研究了投资回报有限期内带有短缺的确定性经济批量订货(EOQ)库存模型,短缺时需求率独立线性依赖于时间,其余时刻的需求率依赖于即时库存量;同时考虑通货膨胀和费用时值的影响,考虑2个独立的通货膨胀率,即内部(公司)通货膨胀率和外部(一般经济)通货膨胀率;通过一个算例对模型的具体情况作简要讨论,并对参数灵敏性进行了分析。

A finite time-horizon deterministic economic order quantity（EOQ） inventory model with shortages is developed, in which the demand linearly dependents on time in the case of shortages and on the on-hand inventory（stock level） in other cases. The effect of the inflation and the time value of money is taken into account, considering two separate inflation rates, namely the internal（company） inflation rate and the external（general economy） inflation rate. The results of the model are discussed with a numerical example, and the sensitivity analysis of the optimal solution with respect to the parameters of the system is carried out.
