In high quality industrial processes, the control chart is design based on cumulative count of conforming (CCC) items is very useful. In this paper, the performance of CCC-r chart with variable sampling intervals (CCC-r VSI chart) in the presence ofinspectionerrors isinvestigated. The efficiency of CCC-r VSI chart is compared with CCC-r chart with fixed sampling interval (CCC-r FSI chart). The comparison results show thatthe VSI scheme can performs better than the FSI scheme. In addition, analysis and discussion of the results are presented to illustrate the effect of input parameters on the performance of CCC-r VSI chart.
