Computing Average Run Lengths for Exponential CUSUM Schemes

Abstract

Exponentially distributed observations arise naturally in the context of monitoring the rate of occurrences of events like nonconforming items. Cumulative sum (CUSUM) control charts are known to be very sensitive in detecting small shifts in the mean. A program is presented for computing average run lengths for CUSUM control charts when observations are exponentially distributed.
