Design of X-Bar Control Chart for Resampling Under Uncertainty Environment [PDF]
IEEE Access, 2019 This paper presents the designing of the X-bar control chart using resampling scheme under the uncertainty environment. The necessary measures of the present chart are derived under the neutrosophic system. The neutrosophic average run length (NARL) when

A New X-Bar Control Chart for Using Neutrosophic Exponentially Weighted Moving Average [PDF]
Mathematics, 2019 The existing Shewhart X-bar control charts using the exponentially weighted moving average statistic are designed under the assumption that all observations are precise, determined, and known.

A Unifying Concept of X Chart and X-Bar Chart when Subgroup Sizes are Equal
Journal of Mathematical and Fundamental Sciences, 2019 X chart and X-bar chart are usually seen as two techniques in SPC with different concepts. In this paper we propose two propositions as a unifying concept for those two charts; one for start-up stage and the other for process control for future ...

Risk-Based X-bar chart with variable sample size and sampling interval
Computers & Industrial Engineering, 2018 Abstract Flexibility is increasingly important in production management, and adaptive control charts (i.e., control charts with variable sample size and/or variable sampling interval) have significant importance in the field of statistical process control. The value of the variable chart parameters depends on the detected process parameters.

An Application X-bar Chart and Statistical Process Control With R Package
UNP Journal of Statistics and Data ScienceQuality control is a critical aspect of ensuring that production processes meet established standards and customer requirements. One widely used approach in Statistical Quality Control (SQC) is the control chart, particularly the X̄ and s charts, which monitor process stability based on the mean and variability of the data.

Statistical Properties and Sensitivity of a New Adaptive Sampling Method for Quality Control [PDF]
Revstat Statistical Journal, 2018 We present a new adaptive sampling method for statistical quality control. In this method, called LSI (Laplace sampling intervals), we use the probability distribution function of the Laplace standard distribution to obtain the sampling instants ...
