Racking and Storage/Retrieval
FEM 9.221 - Performance Data of S/R-Machines – Reliability and Availability
FEM 9.221-EN
Language version
The present FEM Rule contains a standard method for determining the reliability and availability of S/R-machines. This method makes it possible to draw conclusions about the throughput which the user of a high-bay warehouse requires from the manufacturer, throughput being defined as the number of storage and retrieval operations per unit of time.
Throughput depends both on the availability of system units and on the cycle time, which is dealt with in FEM 9.851.
On the basis of theoretical principles, a method for detE:lrmining performance in practice will be described, in which periods of downtime and malfunctions will be differentiated according to areas of responsibility.
