Abstract Some industrial data often come with uncertainty, which in some cases depends on the decision of those responsible for taking measurement production process. While fuzzy approach helps to tackle ambiguity that arises measurement, an interval type-2 set deals such uncertainty better due its flexibility over control limits chart. This paper aims develop Interval Type-2 Exponentially Weig...

We argue against the use of generally weighted moving average (GWMA) control charts. Our primary reasons are following: (1) There is no recursive formula for GWMA chart statistic, so all previous data must be stored and used in calculation each statistic. (2) The Markovian property does not apply to statistics, computer simulation determine limits statistical performance. (3) An appropriately d...
