Determining the level of cyclical and average available stock

The available stock is the stock currently in stock, increased by previously placed orders (in progress) and decreased by any reservations.

The information level of the stock is the stock that, while at the disposal of the ordering party at the time of placing the order (more precisely at the beginning of the replenishment cycle), must cover the demand from the recipients until the ordered delivery can be disposed of. This level depends on:

the average demand observed in the replenishment cycle; of course, this applies to a random component of demand,

standard deviation of this demand (forecast standard error),

safety factor, depending on the agreed level of customer service.

For self-completion:

inventory structure depending on the functions performed;

definitions of terms: inventories, inventory management, cyclical inventory, available inventory, average available inventory;

the economic size of the order - the essence, purpose, pattern, characteristics;

The most important patterns:

average cyclical stock Zc

Zc=12Q ,

where:

Q average delivery volume over the period considered

• average available stock Zdr or average actual warehouse stock ZR

Zdr=Zdn

where:

Zd - stock available in individual termination units

n - number of analyzed termination units in the analyzed period
