The invention relates to a method for the analysis of the compressed-air supply security of a compressed-air system which comprises one or more compressed-air generators (C1, C2) and supplies one or more compressed-air consumers via a compressed-air network (9),
characterized in that a time course of the maximum delivery volumetric flow rate MDVF(t) is recorded, estimated or calculated, that a time course of the consumption volumetric flow rate CVF(t) is recorded, estimated or calculated, and that for the analysis of the compressed-air supply security the time course of the maximum delivery volumetric flow rate MDVF(t) and the time course of the consumption volumetric flow rate CVF(t) are automatically offset against each other over an analysis period.
