Abstract

When T2 control chart is used to monitor a process, it is usually assumed that the samples of size n0 is taken at constant intervals t0. In this paper, we investigate the T2 control chart for monitoring the process mean vector when the sampling intervals are variable. Recent studies have shown that the variable sampling interval (VSI) scheme helps practitioners detect process shifts more quickly than the classical scheme Fixed Ratio Sampling (FRS). In this paper, it is assumed that the length of time the process remains in control is exponentially distributed.
