A new adaptive control chart for the simultaneous monitoring of the mean and variability of multivariate normal processes

چکیده
This paper considers adaptive schemes for the simultaneous monitoring of mean and variability a multivariate normal quality characteristic. At first, we extend an already existing bivariate non-adaptive control chart to one. Then, develop several schemes, which will cover both previously newly charts. After having designed chart, eight performance measures are computed based on run length, time signal, number observations signal switches evaluated using new Markov chain model. With developed measures, under different mean, variability, shift sizes, characteristics compared. Our scheme is also compared one best methods available in literature. A numerical example provided order demonstrate how can be implemented practice.

A Self-starting Control Chart for Simultaneous Monitoring of Mean and Variance of Simple Linear Profiles
In many processes in real practice at the start-up stages the process parameters are not known a priori and there are no initial samples or data for executing Phase I monitoring and estimating the process parameters. In addition, the practitioners are interested in using one control chart instead of two or more for monitoring location and variability of processes. In this paper, we consider a s...
متن کاملSimultaneous Monitoring of Multivariate-Attribute Process Mean and Variability Using Artificial Neural Networks
In some statistical process control applications, the quality of the product is characterized by thecombination of both correlated variable and attributes quality characteristics. In this paper, we propose anovel control scheme based on the combination of two multi-layer perceptron neural networks forsimultaneous monitoring of mean vector as well as the covariance matrix in multivariate-attribu...

wuthering heights and the concept of marality/a sociological study of the novel
to discuss my point, i have collected quite a number of articles, anthologies, and books about "wuthering heights" applying various ideas and theories to this fantastic story. hence, i have come to believe that gadamer and jauss are rightful when they claim that "the individaul human mind is the center and origin of all meaning," 3 that reading literature is a reader-oriented activity, that it ...
