On enhanced control charting for process monitoring
نویسندگان
چکیده
control limits of Zhang (1984) and Wade and Woodall (1993). It has been observed that the proposed charts perform superior, in terms of discriminatory power, as compared to the above mentioned counterparts, depending upon the correlation structure among the auxiliary characteristics and the quality characteristic of interest. The said superiority zone of the correlation structures, favoring the proposed charts, needs to be identified very carefully to apply it in a given situation.

On the Performance of Auxiliary-based Control Charting under Normality and Nonnormality with Estimation Effects
Process monitoring through control charts is a quite popular practice in statistical process control. From a statistical point of view, a superior control chart is the one which has an efficient design structure, for the case of both known and unknown parameters. There are auxiliary information–based location charts for an improved monitoring of process mean level. These charting structures hav...
متن کاملA Review and Evaluation of Statistical Process Control Methods in Monitoring Process Mean and Variance Simultaneously
In this paper, first the available single charting methods, which have been proposed to detect simultaneous shifts in a single process mean and variance, are reviewed. Then, by designing proper simulation studies these methods are evaluated in terms of in-control and out-ofcontrol average run length criteria (ARL). The results of these simulation experiments show that the EWMA and EWMS methods ...
متن کاملA Forecast-based Monitoring Methodology for Process Transitions
Nonconfonning parts are often produced when a process moves from one level to another due to transition events. Control charting, when applied to a stable state process, is an effective monitoring tool to continuously check for process shifts or upsets. However, the presence of transition events can impede the nonnal perfonnance of traditional control chart with increased false alarms. The pres...
متن کاملMultivariate Statistical Process Control Charts and the Problem of Interpretation: A Short Overview and Some Applications in Industry
Woodall and Montgomery [35] in a discussion paper, state that multivariate process control is one of the most rapidly developing sections of statistical process control. Nowadays, in industry, there are many situations in which the simultaneous monitoring or control, of two or more related quality process characteristics is necessary. Process monitoring problems in which several related variabl...
متن کاملA spatial rank-based multivariate EWMA control chart
Nonparametric control charts are useful in statistical process control (SPC) when there is a lack of or limited knowledge about the underlying process distribution, especially when the process measurement is multivariate. This paper develops a new multivariate self-starting methodology for monitoring location parameters. It is based on adapting the multivariate spatial rank to on-line sequentia...
