On fuzzy and probabilistic control charts
International Journal of Production Research, 2002In this article, different procedures of constructing control charts for linguistic data, based on fuzzy and probability theory, are discussed. Three sets of membership functions, with different degrees of fuzziness, are proposed for fuzzy approaches.

Fuzzy Control Charts based on Ranking of Pentagonal Fuzzy Numbers
2023A Control Chart is a fundamental approach in Statistical Process Control. When uncommon causes of variability are present, sample averages will plot beyond the control boundaries, making the control chart a particularly effective process monitoring approach.

Fuzzy Control Chart A Better Alternative for Shewhart Average Chart
Quality & Quantity, 2006This paper through a real illustrative example and a power test shows that designing a fuzzy control chart for process average of a continuous (variable) quality characteristic with a warning line is a better alternative to Shewhart \(\bar{X}\) chart in many respects, like providing better neural view to inspectors, offering different strategic options

Fuzzy process control: construction of control charts with fuzzy numbers
Fuzzy Sets and Systems, 2005This paper presents the construction of fuzzy control charts for a process with fuzzy outcomes derived from the subjective quality ratings provided by a group of experts. The proposed fuzzy process control (FPC) methodology comprises an off-line stage and an on-line stage.

Fuzzy theory and quality control charts
2017 IEEE International Conference on Fuzzy Systems (FUZZ-IEEE), 2017Quality control charts are one of the most important tools of statistical process control, used to analyze the behavior of different processes and to predict possible production failures. The use of a fuzzy approach in the design of control charts has allowed to improve the performance of traditional charts, as well as to be possible of a simple ...

Monitoring Welding Discontinuities with Fuzzy Control Chart
Advanced Materials Research, 2014Over 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.
