DOI: 10.1002/cem.3213
Abstract: The sound tolerance interval–based method and two Pp–based approximations are compared on the proportion of nonconforming parts. As output distribution of the process, one possible model is examined here: two sources of variations are in… read more here.

DOI: 10.1007/s40314-018-0657-8
Abstract: This study has developed an approach to statistical process control indices for imprecise observations induced from an arbitrary population. For this purpose, most popular non-normal process capability index was extended based on a proposed triangular… read more here.

DOI: 10.1093/jrr/rrab079
Abstract: Since there are no corresponding specification limits for some new daily quality assurance (QA) items in the TG-142, it is a compromise that the specification limits used in the monthly or annual QA procedures are… read more here.
