Fuzzy analysis for higher effectiveness of control chart

International Journal of Quality and Innovation, 2011
This paper addresses the problems occurring in the control chart and develops a new way to improve the evaluation process of this widely used tool. Classical limitation of control chart is its inability to accurately diagnose the out of control situation. In the Shewhart's control chart, the effects of the variation of the process points plotted on the

Fuzzy rules for fuzzy $\overline{X}$ and $R$ control charts

2014
Statistical process control ($SPC$), an internationally recognized technique for improving product quality and productivity, has been widely employed in various industries. $SPC$ relies on the use of control charts to monitor a manufacturing process for identifying causes of process variation and signaling the necessity of corrective action for the ...

Fuzzy multinomial control chart and its application

AIP Conference Proceedings, 2016
Control chart is a technique that has been used widely in industry and services. P chart is the simplest control chart. In this chart, item is classified into two categories as either conforming and non conforming. This chart based on binomial distribution.

Monitoring Welding Discontinuities with Fuzzy Control Chart

Advanced Materials Research, 2014
Over the past few years, several extensions of the traditional control charts have been proposed to adapt to the fuzziness inevitably existing in practical manufacturing processes. This paper proposed a fuzzy u chart to monitor the nonconformity of industrial products.

A STUDY ON THE COMPARISION BETWEEN FUZZY CONTROL CHARTS AND TRADITIONAL CONTROL CHARTS

2018
Itis crucial that the gaining continuity of quality that has become increasinglyimportant especially after the Second World War and has become an indispensableconcept for both firms and consumers since the late nineteenth century. Toensure this continuity, enterprises in manufacturing and in the service sectorare in an effort to periodically check the ...

Fuzzy individual and moving range control charts with α-cuts

Journal of Intelligent & Fuzzy Systems: Applications in Engineering and Technology, 2008
In Statistical Process Control (SPC), both variable and attribute control charts are widely used techniques to monitor and evaluate the process with respect to the related quality characteristics. In variable control charts, quality characteristics are measured on a numerical scale, using two main parameters mean and standard deviation.
