This study proposes a control chart to monitor turnaround time (TAT) of biochemical test of laboratory for a medical center.Constants of average control chart are calculated in accordance with fixing probability of type I error (a, 0.0027) with threedistributions (Weibull, lognormal and Burr) by using Monte Carlo simulation. This study also compared probabilities of type Iand type II errors (<img src='/image/spc_char/beta.gif' border=0>) among control charts, including weighted variance (WV), skewed correction (SC) and traditional Shewhartcontrol charts. Control chart with asymmetrical control limits using proposed constants based on subgroups is superior in termsof two probabilities for a skewed process. |
