Explicit analytical solutions for the average run length of modified EWMA control chart for ARX(p,r) processes [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2021
Statistical process control (SPC) plays a necessary role in manufacturing industry processes. An essential tool for SPC used for monitoring, measuring, controlling, and improving quality in various fields is the control chart.

A New Control Chart for Monitoring Reliability Using Sudden Death Testing Under Weibull Distribution

open access: yesIEEE Access, 2017
In this paper, a new control chart using sudden death testing is designed by assuming that the lifetime/failure time of the product follows the Weibull distribution. The structure of the proposed chart is presented.

A Variable Control Chart under the Truncated Life Test for a Weibull Distribution

open access: yesTechnologies, 2018
In this manuscript, a variable control chart under the time truncated life test for the Weibull distribution is presented. The procedure of the proposed control chart is given and its run length properties are derived for the shifted process. The control

A Comparison of Shewhart-Type Time-Between-Events Control Charts Based on the Renewal Process

open access: yesIEEE Access, 2020
To study the high quality processes, time-between-events (TBE) control charts have several advantages over the ordinary control charts. However, the existing TBE charts are based on the exponential distribution, which limit the application of these ...

The np Chart with Guaranteed In‐control Average Run Lengths [PDF]

open access: yesQuality and Reliability Engineering International, 2016
We evaluate the in‐control performance of the np‐control chart with estimated parameter conditional on the Phase I sample. We then apply the bootstrap method to adjust the control chart limits to guarantee the desired in‐control average run length (ARL0) value in the monitoring stage.

On the average running time of odd-even merge sort [PDF]

open access: yes, 1995
This paper is concerned with the average running time of Batcher's odd-even merge sort when implemented on a collection of processors. We consider the case where $n$, the size of the input, is an arbitrary multiple of the number $p$ of processors used ...

A Multivariate Control Chart for Monitoring Several Exponential Quality Characteristics Using EWMA

open access: yesIEEE Access, 2018
In this paper, we propose a new multivariate control chart for monitoring several exponential distributed characteristics. We transform each exponential variable into the one following an approximately normal distribution.

Average-case analysis of perfect sorting by reversals (Journal Version) [PDF]

open access: yes, 2011
Perfect sorting by reversals, a problem originating in computational genomics, is the process of sorting a signed permutation to either the identity or to the reversed identity permutation, by a sequence of reversals that do not break any common interval.

Monitoring Reliability for Three-Parameter Frechet Distribution Using Control Charts

open access: yesIEEE Access, 2020
Control Charts for attributes have been widely adopted for examining the fraction non-conforming or non-conformities in a process. However, Shewhart control charts may face some practical problems when the process fraction of non-conformities is very low.
