Max-Half-Mchart: A Simultaneous Control Chart Using a Half-Normal Distribution for Subgroup Observations

IEEE Access, 2021
A Simultaneous control chart is a well-known tool for monitoring the process mean and process variability with a single chart. In recent decades, many researchers have been interested in developing simultaneous control charts.

Attribute Control Chart Using the Repetitive Sampling Under Neutrosophic System

IEEE Access, 2019
In this paper, an attribute control chart using the repetitive sampling under the neutrosophic statistics system is discussed. The necessary measures of the proposed control chart under the neutrosophic statistics system are given.

Steady-state behavior of nonparametric control charts using sign statistic

Production, 2015
If process is running for a long period in an in-control condition, it will reach in a steady-state condition. In order to study the long term properties of a control chart, it is appropriate to investigate the steady-state average time to signal.

Reinforcement Learning-Based Real-Time Contrasts Control Chart Using an Adaptive Window Size

IEEE Access
In this study, we propose a real-time contrasts control chart based on reinforcement learning (RL-RTC). Effective process monitoring, which directly influences productivity and yield, has become increasingly important.

Control Chart Interpretation Using Fuzzy ARTMAP

Journal of King Saud University: Engineering Sciences, 2004
Fuzzy ARTMAP is a newly introduced artificial neural network architecture that incorporates fuzzy logic into its dynamics. In this paper, fuzzy ARTMAP is used to: i) decide whether a production process is under statistical control or out of control and ...

Control Chart for Variance Using Repetitive Sampling Under Neutrosophic Statistical Interval System

IEEE Access, 2019
In this paper, a control chart for variance using the repetitive sampling under the neutrosophic statistics is proposed. The proposed control chart can be applied for monitoring the variability in the process when some observations/parameters are unclear

Poisson regression charts for the monitoring of surveillance time series [PDF]

, 2006
This paper presents a Poisson control chart for monitoring time series of counts typically arising in the surveillance of infectious diseases. The in-control mean is assumed to be time-varying and linear on the log-scale with intercept and seasonal ...

A Binary Control Chart to Detect Small Jumps [PDF]

, 2009
The classic N p chart gives a signal if the number of successes in a sequence of inde- pendent binary variables exceeds a control limit. Motivated by engineering applications in industrial image processing and, to some extent, financial statistics, we ...
