顾客对缺货数量和等待时间的敏感度影响着部分短缺量拖后率。基于此,根据顾客对缺货数量和等待时间的敏感度以及成本结构,对部分短缺量拖后下不同补货策略的适用范围进行了研究,得出以下结论:(s,S)连续性检查策略适用于单位缺货和丢单成本较高的库存系统;(t,S)周期性检查策略和(t,s,S)混合策略适用于单位缺货和丢单成本较低的库存系统;在单位缺货和丢单成本较低的库存系统中,当顾客对缺货数量较敏感时,(t,s,S)混合策略的运作成本更低,否则(t,S)周期性检查策略更适用,而顾客对等待时间的敏感度对补货策略适用范围的影响不明显。 The sensitivity of the customer to the out-of-stock quantity and waiting time affects the postponement rate of some shortages. Based on this, according to the customer’s sensitivity to the shortage and waiting time and the cost structure, the paper studies the scope of application of different replenishment strategies after some shortage, and draws the following conclusions: (s, S) Continuity check (T, S) periodic inspection strategy and (t, s, S) hybrid strategy are suitable for inventory systems with unit out-of-stock and lost-lost orders costs; In the inventory system with unit out-of-stock and lost-throw costs, the (t, s, S) hybrid strategy has lower operation cost when the customer is more sensitive to out-of-stock quantity, otherwise the periodic check strategy More applicable, and the sensitivity of the customer to the waiting time has no obvious effect on the scope of the replenishment policy.
