POSSIBILITIES FOR GRAPHIC REPRESENTATION OF MULTIFACTOR SIMPLEX OPTIMIZATION

The progress of a multifactor simplex optimisation algorithm has been plotted in a visual mode, after a reduction in the number of factors u sing the statistic principal component analysis method. The effectiven ess of the proposed graphic representation has been evaluated when app lied to simplex previously published optimisation methods such as: col orimetric determination of cholesterol, flow-injection spectrophotomet ric determination of promethazine and synthesis of an industrial pyraz olone. The procedure has also been applied to develop new experimental analytical methods like the determination of arsenic trichloride by i nductively coupled plasma atomic emission spectrometry.
