Sentence examples for variable sample sizes from inspiring English sources

It is much faster to detect out-of-control cases compared with the ¯¯¯X and CUSUM charts, even their VSSI (Variable Sample Sizes and Sampling Intervals) versions.

We construct variable sample sizes and sampling intervals (VSSI) control charts to effectively monitor the input variable and the output variable produced by a cascade process.

The optimum VSSI control charts are also proposed using optimization technique when quality engineers cannot specify the values of the variable sample sizes and sampling intervals.

Recent studies has demonstrated the adaptive (i.e., variable sample sizes, sampling intervals, and/or action limit coefficients) ¯X charts are quicker than standard Shewhart (SS) ¯X control chart in detecting process mean shifts.

It has been found that the optimum VSSI control charts work and are thus suggested whenever quality engineers cannot specify the values of variable sample sizes and sampling intervals.

Five mapping pedigrees (P1-P5) of variable sample sizes were used (Table 1), consisting of one Q.

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.

Recent theoretical studies demonstrated the variable sampling rate (variable sample size and/or sampling interval) ¯¯¯X charts are quicker than standard Shewhart (SS) ¯¯¯X control charts in detecting process mean shifts.

An ¯¯¯X chart with variable sample size and sampling interval (VSSI) has been shown superior to the traditional ¯¯¯X chart with fixed sample size and sampling interval.

The superiority of the proposed model is estimated by comparing its expected quality control cost vs. the outcome of the Fp (Fixed-parameter) Shewhart control chart, the Variable Sample Size (VSS) control chart, the Variable Sampling Interval (VSI) and the Variable Sample Size and Sampling Interval (VSSI) control chart, for a benchmark of examples.

This paper proposes a risk-based concept for the design of an X-bar chart with variable sample size and sampling interval.
