季节性需求多阶段库存控制策略研究

Multi-stage Inventory Control under Seasonal Demand Distribution Function

研究了确定型季节模型多阶段库存控制策略。具体的思路为:首先把各时期需求的季节指数求出,季节调整后进行密度估计。当需求有关的分布函数得到后,按照多阶段库存系统的最优策略公式可以得到季节调整后库存最优策略。然后再加入季节指数,就得到了随季节变动的库存最优策略。

The paper studies the strategy of multi - stage seasonal inventory model. The ideas is first to calculate all season the seasonal demand index, then estimates the density after seasonal adjustment. As long as the distribution function is got, optimal inventory strategies will be got after seasonal factors removed in accordance with the multi - stage strategy of the optimal inventory system formula. Then the optimal inventory strategies will be got along with the seasons change after joining the season index.
