The synthetic control chart based on two sample variances for monitoring the covariance matrix
TLDR
We propose a new statistic to control the covariance matrix of bivariate processes based on the sample variances of the two quality characteristics, in short VMAX statistic. Expand

Economic design of ?? andR charts under Weibull shock models
This paper deals with the joint economic design of x and R charts when the occurrence times of assignable causes follow Weibull distributions with increasing failure rates. The variable qualityExpand

Economic design of VSI control charts
Duncan considered the design parameters of Shewhart control charts in 1956 based on an economic view-point, and ensured that an economic design control chart actually lowers the cost compared with aExpand

New adaptive control charts for monitoring the multivariate coefficient of variation
TLDR
This paper proposes three adaptive charts to monitor the multivariate coefficient of variation (MCV), in order to improve the sensitivity of the standard MCV chart, in detecting small and moderate MCV shifts. Expand

The non-central chi-square chart with two-stage samplings
TLDR
We propose the non-central chi-square chart with two stage samplings, which is not only more sensitive than the joint X and R charts, but operationally simpler too. Expand

Reducing performance variation in the canning problem
Abstract Modern quality management practices recommend the elimination of fixed numerical goals, in favour of programs designed to continuously reduce the process variability. The ultimate purpose isExpand
