Cycle counting is a periodic analysis of inventory in a storage location which is conducted through the counting of samples instead of physically counting the entire inventory available, so as to quickly have an accurate estimate of the inventory available without causing a stop to the day to day working as is the case with physically counting every unit.
The Pareto principle (also known as the 80/20 rule, the law of the vital few, or the principle of fac-tor sparsity) states that, for many events, roughly 80% of the effects come from 20% of the causes.
Weighted moving averages assign a heavier weighting to more current data points since they are more relevant than data points in the distant past. The sum of the weighting should add up to 1 (or 100 percent).

If the planning and mitigation measures fail and redundant or obsolete stock is identified, it needs to be removed from the current inventory location as quickly as possible. There are some methods to deal with these types of stock. The worst case scenario is disposal to landfill, which is inadvisable if it can be avoided, both from environment point of view and the financial costs of such disposal.
For example, the problem of obsolete pesticides remains extremely serious and urgent. Many of the stocks identified continue to deteriorate thereby giving rise to an ever escalating source of severe pollution and posing a threat to human health, the environment and development in particular. To reduce the impact of obsolete pesticides on environment, FAO initiated a project in Yemen in which a total of 262 tonnes of obsolete pesticides were removed from 20 different sites and successfully disposed of between March and June 1996. The major field operation was completed in six weeks during which period almost all obsolete pesticides were brought to a central location and subsequently shipped to the United Kingdom for incineration.

There are many different factors that must be considered when assessing warehouse and stock locations:
* Operating cost of the location or area
* Availability and suitability of warehouses
* Availability of manpower or labour
* Proximity to suppliers and customers
* Access to transport infrastructure (domestic and international)
* The political and security environment of the location

In management accounting, reorder level (or reorder point) is the inventory level at which a com-pany would place a new order or start a new manufacturing run.
Reorder level depends on a company's work-order lead time and its demand during that time and whether the company maintain a safety stock.
If a company maintains a safety stock, reorder level calculation changes are follows:
Reorder Level = Average Demand × Lead Time + Safety Stock
