Product evaluation using uncertainty-based process capability index

Abstract

This paper introduces a new process capability index (PCI) under neutrosophic statistics. The proposed neutrosophic process capability index (NPCI) can be applied to evaluate the status of the industrial process in the presence of Neutrosophy. A new form of PCI is presented to deal with the uncertainty in the system. The performance of the proposed NPCI is checked using the specification limits of some real industrial datasets. By comparing the new NPCI with existing PCI, it is noted that the proposed NPCI provides the measure in indeterminacy interval which makes it more convenient to apply in an uncertain/indeterminate environment.
