An Overview of the Fuzzy Sets on Process Capability Analysis

Journal Title: Quality Procedings - Year 2017, Vol 10, Issue

Abstract

Process capability analysis (PCA) is the ability of a process that measures the degree of providing customer expectations. Generally, the expectations of customer have been defined by using specification limits. A process capability index (PCI) summarizes ability of process to conform specification limits. Generally, this comparison is made by analyzing ratio of specification limits and six-sigma limits. After the inception of the fuzzy set theory (FST) by Zadeh in 1965, PCA has been greatly influenced at a significant level. It is possible to see many papers about usage of the FST on PCA. In this paper, the effects of the FST on PCA have been analyzed and the recent trends have been summarized. By the way, a roadmap about possible future directions of the FST has been suggested.
