in this paper a novel process monitoring scheme for reducing the type і and type іі error rates in the monitoring phase is proposed. first, the proposed approach uses an augmented data matrix to implement the process dynamic. then, we apply independent component analysis (ica) transformation to the augmented data matrix, and eliminate the outliers using the local outlier factor (lof) algorithm....

There have been some advances in multivariate control charts recent years. This paper presents a new simultaneous scheme for monitoring both the mean and variability of normal process single chart, which is developed by improving modifying another recently proposed scheme. We not only propose but also make it adaptive varying all chart parameters. Our scheme, first time, considers two forms: “c...

In this work, the ethanol fuel dehydration process was optimized using Aspen Plus? simulator and a multivariate statistical technique based on desirability function. The suitability of ionic liquids 1-methylimidazolium chloride ([Mim][Cl]), 1-ethyl-3-methylimidazolium ([Emim][Cl]), 1-butyl- -3-methylimidazolium ([Bmim][Cl]) 1-hexyl-3-methylimidazolium ([Hmim][Cl]), as extractive distillation en...
