According to the system of goods issue, we distinguish two systems that depend on the properties of the material, in particular the loss of value of the material due to aging. These two systems are FIFO and LIFO.

  • First in – First out system, where we have to ensure that the goods we store earlier can be dispensed earlier (various shelving systems), and
  • First in – Last out system, where the above principle does not have to be fulfilled.
