The program calculates the threshold limit to switch the adaptive design parameters and also provides the in-control average time to signal, or ATS.455-458engAdaptive Control SchemesAdjusted Average Time to SignalQuality ControlStatistical Process ControlVariable Parameters Control ChartsArtigoAcesso restrito2-s2.0-0001563923
