Process Capability Indices as Fuzzy Numbers

Blog Article

Most of the traditional methods for assessing the capability of manufacturing processes are Bike Units - Fat Bikes dealing with crisp quality.In this paper we discuss the fuzzy quality and introduce fuzzy process capability indices, where instead of precise quality we have two membership functions for specification limits.These indices are necessary when the specification limits are Vitamin B Supplements fuzzy and they are helpful for comparing manufacturing processes with fuzzy specification limits.Some interesting relations among the introduced indices are obtained.Numerical examples are given to clarify the method.
