Storekeeping means the intended interruption of the operational flow of material, i.e. consciously formed existence develop. The storekeeping requires a camp, i.e. an area, a building or an area, in which goods or goods can be kept.

A camp takes over a number of different functions.

For camps with special security is also - originally from Arab military affairs coming - the expression magazine.

Functions of the storekeeping

If the procurement quantity is larger than the output, then by the balance function the material redundant for production is stored. A camp can be used therefore as buffers, in order to compensate fluctuations of the purchase and/or sales sale.

With the supply or assortment function the storekeeping contributes to a continuity in the assortment. To that extent the supply function supplements the balance function, since thereby the parts of the assortment, where discrepancy between procurement and paragraph exists, are bridged.

With the security function the camp serves production for the Sicherstellung, if insufficiently information is over future Mengenbedarfe, supply and need times in the enterprise present. This can be the case, if products, which are coined/shaped by delivery bottlenecks and/or seasonal fluctuations, must be procured.

The improving function is called also production function of the camp, which makes possible only a following processing. An improving function develops, if the storage causes a change of the product and part of the production process (Bsp: Wine, cheese, whisky, Bourbon"…) is.

Reasons for the speculation function of the storage can be foreseeable extreme price fluctuations on the procurement market or particularly low cost prices. In addition can be speculated to the discounts received thereby by the order of large quantities and in camp commodity. However this can affect itself with a price purge of the property also negatively, e.g. with hardware.

Camp strategies and/or - proceed

With the Fifo principle (roofridge in - roofridge Out) the supplies stored first are also again first paged out. For the realization run shelves are often used. To avoid this principle applied over for example obsolescence or decay.

With the Lifo principle (load in - roofridge Out) the supplies stored last are first paged out. To make possible with this camp strategy usually module shelves used over for example in case of the block storage fast access.

With the two further camp strategies, Hifo principle (Highest in - roofridge Out) and Lofo principle (Lowest in - roofridge Out) during the stock pile assignment the underlying in each case evaluation beginnings of the stored materials are considered.


The organization of the camps can take place according to different criteria:

after the stock pile allocation

The planning of the stock level places must take place under the condition that the production points must be supplied sequentially with the necessary materials:

During the firm stock pile allocation for each article firm stock piles are made available, which are reserved for these articles only ("same to same one "). The advantage is in the exact assignableness of the stock location, whereby the high space requirement represents a disadvantage.

During the free (chaotic) stock pile allocation (open warehouse system) the articles at a free stock pile are stored. An advantage of this method is that, if disturbances arise for example in a camp lane the same material can be taken by another camp lane. In order to ensure the later access to the camp articles, however the stock piles must be documented exactly.

after the centralization degree

With the choice of stock level places it must be decided whether the camp is led central or decentralized. With the decision over the centralization degrees frequently the spatial aspect is decisive:

Central storekeeping means the spatial summary of all storekeeping functions and all stored materials under uniform line. The advantages, which result from the central storage, are an easement of the goods received, care, preservation, inventory determination and - examination. Further points are the small capital freeze of the circulating capital, smaller supplies and smaller space costs.

During the decentralized storekeeping the materials used at the place of the user are stored in the form of temporary storage facilities (buffer camp). The substantial advantages of this storage method are the higher flexibility, the more exact arrangement of the individual materials in the production areas and the shorter routes of transportation.

after the execution form

  • Camp for gases (gas memory)
  • Camp for liquids (receiver, water tower)
  • Camp for bulk material (silo)
  • Block camp, e.g. for containers
  • Automatic warehouse


A stock as such is at a certain time the quantity of a property in the camp. The following special existence are of importance:

Minimum stocks (also safety stock amount or becomes outdated iron existence/reserve) are the stock, which may be never fallen below, in order to be able to keep production upright also in emergencies. It must always be in stock and is defined by the production management. It may not be fallen below without express arrangement of the production management.

With reaching the notifiable stock level a message is triggered by withdrawals from the stock to the purchase for replenishment of the camp - by an order -. The notifiable stock level determines thus the due order lead date.

Notifiable stock level = \ mathrm {daily requirement} \ times \ mathrm {procurement time + minimum stocks}

The maximum or maximum stocks is the existence, which may be maximally in the camp present, in order to prevent high costs and a high capital freeze.

Maximum existence \ = \ mathrm {minimum stocks + incoming goods}
