An inventory model for deteriorating items with linear trend demand under the condition of permissible delay in payments
研究了在允许延迟支付条件下，需求呈线性趋势且产品会变质时的库存补货问题，提出了确定最优补货周期的算法，并用数值例子验证了模型。
In this article, we consider the inventory replenishment problem with varying rate of deterioration and condition of permissible delay in payments, in which the restrictive assumption of constant demand rate is relaxed, and take a linear trend in demand into consideration. An algorithm is developed to determine the optimal replenishment cycle. We also provide a special case to illustrate the proposed model. Finally, a numerical example is presented to illustrate the optimization procedure. Sensitivity analysis of the parameter value is also carried out.
