A Time Truncated Moving Average Chart for the Weibull Distribution
IEEE Access, 2017 A control chart of monitoring the number of failures is proposed with a moving average scheme, when the life of an item follows a Weibull distribution.

A fuzzy nonparametric Shewhart chart based on the bootstrap approach
International Journal of Applied Mathematics and Computer Science, 2015 In this paper, we consider a nonparametric Shewhart chart for fuzzy data. We utilize the fuzzy data without transforming them into a real-valued scalar (a representative value).

Design of a Control Chart Using Extended EWMA Statistic
Technologies, 2018 In the present paper, we propose a control chart based on extended exponentially weighted moving average (EEWMA) statistic to detect a quick shift in the mean. The mean and variance expression of the proposed EEWMA statistic are derived.

Efficient Phase II Monitoring Methods for Linear Profiles Under the Random Effect Model
IEEE Access, 2019 A profile is a functional relationship between two or more variables used to monitor the process performance and its quality. Sometimes, the aforementioned relationship is linear or nonlinear depending upon the situation. A monitoring method based on the

On designing a sequential based EWMA structure for efficient process monitoring
Journal of Taibah University for Science, 2020 Control chart is a popular technique that is widely used in statistical process control to identify any possible deviations from a stable state of a process. Shewhart charts are famous for identifying larger shifts, while cumulative sum and exponentially

Analytical explicit formulas of average run length for long memory process with ARFIMA model on CUSUM control chart [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2017 This paper proposes the explicit formulas for the derivation of exact formulas from Average Run Lengths (ARLs) using integral equation on CUSUM control chart when observations are long memory processes with exponential white noise. The authors compared
