This paper attempts to develop a sampling inspection scheme by variables based on process performance index for product acceptance determination, which examines the situation where resampling is permitted on lots not accepted on original inspection. The equations for plan parameters, the...

It has been proved that process capability indices provide very efficient measures of the capability of processes from many different perspectives. At the present time, the Cpk index is used more than any other index for measuring process capability. However, most existing research works for...

Over the years, numerous process capability indices (PCIs) have been proposed to the manufacturing industry to provide numerical measures of process performance. Most research efforts have focused on developing and investigating PCIs that assess process capability by precise measurements of...
