2. Control Chart Recognition Patterns using Fuzzy Rule-Based System

Alireza Alinezhad; Ali Taherinezhad

Volume 12, Issue 2 , Autumn 2020, Pages 149-160

  Control Chart Patterns (CCPs) recognition is one the most important concepts in control chart application. Relating the patterns exhibited on the control chart to assignable causes is an ambiguous and vague task especially when multiple patterns co-exist. In this study, a fuzzy rule-based system is developed ...  Read More
