A variable sampling interval run sum chart for the coefficient of variation

This paper proposes a variable sampling interval (VSI) run sum chart for the coefficient of variation (gamma), where the sampling interval is varied according to the current cumulative scores. Formulae to evaluate various performance measures for the proposed chart are derived, and algorithms to opt...
