Company A agrees to use a self-designed Demand-pull method as an operational mode of the warehouse to replenish to stores. But the effect is not very significant. Suggesting that the reason for the self-designed method has not been perfect, causing the operator not to follow the instruction of system but by their own experience to replenish. First, this paper analyzes historical sales and inventory data provided by company A to get the current situation, and then compared with the result of completely in accordance with Demand-pull method simulated by Excel. Prove that the target inventory of Demand-pull method designed by company A changes in low frequency, causing it not to immediately response to variability of demand. As a result, it will cause a serious shortage. So the performance is indeed not better than the current situation. Second, after we understand the problem, we can give some recommendations for improvement. Demand-pull method needs to increase the initial target inventory and the quantity of first order, and that can solve the shortage problem. However, the problem of target inventory changing in low frequency still persists, so this paper uses another method changing in high frequency called DDMRP method. Like Demand-pull method, we use Excel to analysis. And find that not only the remaining inventory reduced by 50% compared to the current situation, but the net profit increased by 10%. It is very suitable for the warehouse of company A to use.
