时变需求下零售商补货时点的优化决策研究

The optimized decision research of retail dealer filling goods time-point under the time-variable demand

构建了时变需求下零售商的库存成本模型,并通过算例比较了等周期补货与非等周期补货模式下零售商补货时点的区别,分析了在时变需下非等周期补货模式存在的优越性;通过设定不同的时变因子取值,得出平稳需求条件下零售商宜采取等周期补货模式、时变需求下零售商宜采取非等周期模式的结论。

The stock cost model of retail dealer under the time-variable demand was structured. The difference between the cycles filling the goods pattern and the non-cycles filling the goods pattern were pointed out basing on a calculated example. The superiority of the non-cycles filling the goods pattern under the time-variable demand was obtained. Through setting different time-variable factor value, it was concluded that retail dealer should adopt the cycles filling the goods pattern under the steady demand and adopt the non-cycles filling the goods pattern under the time-variable demand.
