CONSTRUCTION OF FUZZY C CONTROL CHARTS BASED ON FUZZY RULE METHOD

open access: yesANADOLU UNIVERSITY JOURNAL OF SCIENCE AND TECHNOLOGY A - Applied Sciences and Engineering, 2017
A control chart is a tool that is used for representing and monitoring the process. Also control chart detected process shifts and abnormal conditions in a process. In a process monitored the c control charts, due to the uncertainty of the attribute data, c control chart may not applicable for the process since it’s required certain information.

A Literature Review on the Fuzzy Control Chart; Classifications & Analysis [PDF]

open access: yesInternational Journal of Supply and Operations Management, 2014
Quality control plays an important role in increasing the product quality. Fuzzy control charts are more sensitive than Shewhart control chart. Hence, the correct use of fuzzy control chart leads to producing better-quality products. This area is complex

Evaluating the Packing Process in Food Industry Using Fuzzy X and S Control Charts [PDF]

open access: yesInternational Journal of Computational Intelligence Systems, 2011
The fuzzy set theory addresses the development of concepts and techniques for dealing with uncertainty or impression conditions. If the collected data from a process include vagueness due to human subjectively or measurement system, fuzzy control charts ...

Implementation of fuzzy rule-based algorithms in p control chart to improve the performance of statistical process control [PDF]

open access: yesInternational Journal of Research in Industrial Engineering, 2018
In the statistical process control when the process is very sensitive and control limit shifts are the prime concerns, there fuzzy control charts can be a better solution.

Fuzzy Regression Control Chart Based on α-cut Approximation [PDF]

open access: yesInternational Journal of Computational Intelligence Systems, 2010
The fuzzy regression control chart is a functional technique to evaluate the process in which the average has a trend and the data represents a linguistic or approximate value. In this study, the theoretical structure of the “α-level fuzzy midrange for α-

A Fuzzy Bivariate Poisson Control Chart [PDF]

open access: yesSymmetry, 2020
In the present paper, we develop a fuzzy bivariate Poisson (FBP) control chart based on a fuzzy c chart. The FBP chart is used to monitor the sum of the nonconformities of each quality characteristic. There are two contributions of this work. First, we propose a new fuzzy parameter estimation to create a triangular fuzzy number (TFN).

A Fuzzy EWMA Attribute Control Chart to Monitor Process Mean

open access: yesInformation, 2018
Conventional control charts are one of the most important techniques in statistical process control which are used to assess the performance of processes to see whether they are in- or out-of-control.
