A new generation of process capability indices

Parchami, A.; Mashinchi, M. - In: Journal of Applied Statistics 37 (2010) 1, pp. 77-89

In quality control, we may confront imprecise concepts. One case is a situation in which upper and lower specification … limits (SLs) are imprecise. If we introduce vagueness into SLs, we face quite new, reasonable and interesting processes, and …

A Capability Index Calibrated to the Nonconformance Probability

Ho, Linda Lee; Borges, Wagner Sousa; Barriga, Glady D. C. - In: Stochastics and Quality Control 19 (2004) 1, pp. 45-59

Abstract Process Capability indices have become popular for describing how well a process meets specified tolerances. The lack of affinity with the process nonconformance probability p and the difficulty of dealing with the sampling distribution of their natural estimators affect greatly the use...

Determining the Optimum Process Mean of a One-sided Specification Limit with the Linear Quality Loss Function of Product

Chen, Chung-Ho - In: Journal of Applied Statistics 31 (2004) 6, pp. 693-703

Wen & Mergen (1999) proposed a method for setting the optimal process mean when a process was not capable of meeting specifications in the short term. However, they neglected to consider the quality loss for a product within specifications in the model. Chen & Chou (2002) presented a modified...

Squared Error Loss of Process Capability Indices

Chen, Chung-Ho; Chou, Chao-Yu - In: Stochastics and Quality Control 16 (2001) 2, pp. 205-209

Abstract In this paper, we extend Johnson's work [Johnson, T. Journal of Quality Technology 24: 211-215, 1992] of formulating the relationship between process capability indices (PCI) and expected squared error losses. Moreover, a comparison is made between the expected squared error loss of PCI...
