a stock rotation policy that the most recently arrived item is processed first. A stack implements this.
程序来确定库存量，这通常是基于佩瑞多分析法并结合 ABC分析法来进行的。
Vilfredo Pareto, a 19th century economist, observed that 80% of Italy's wealth was owned by 20% of the population. This is often referred to as the ‘80/20 rule’, meaning that, in such cases, 80% of the items in stock typically make up only 20% of the total stock value, while the remaining 20% of (high-value) items account for 80% of the total stock value.

其目的是在过多库存和过少 库存的两个极端之间取 得平衡。
Holding a high level of stock is a simple policy to manage and reduces the risk of stockouts. Moreover, by reducing the need for frequent orders, it also reduces the administrative costs of purchasing stocks. However, it increases the stockholding costs.

However, it reduces the stockholding costs
