FUZZY PROCESS ACCURACY INDEX AS A DECISION MAKING TOOL

Abstract

Process capability indices are summary statistics to point out the process performance. In the literature, various capability indices are used for this aim. Process accuracy index (Ca) measures the degree of the process centering and gives alerts when the process mean departures from the target value is analyzed when the specification limits and process mean are fuzzy. A theoretical application is illustrated to show the usage of C̄a.
