摘要
研究了通货膨胀下允许延期支付的变质率和需求率均为非常数的商品库存模型。分析了满足上述条件的4种不同情形下的变质商品总库存成本函数,提出了变质商品的最优库存补充决策。通过算例对理论结果作了说明,并分别就最小订购量、延期期限、订购费用和通货膨胀率对最优解作了灵敏度分析。
This paper studies an inventory model of deteriorating items with non-constant deterioration rate and demand rate under inflation and permissible delay payments. The total inventory cost functions of four cases under the conditions above are analysed. An optimal replenishment policy of deteriorating items is proposed. Finally, numerical examples are given to illustrate the theoretical results and made the sensitivity analysis of parameters such as minimum order quantity, permissible delay, ordering cost and rate of inflation on the optimal solutions.
