These update schemes have been applied to the successful prediction of Melt Index (MI) in grade-change operations of High Density Polyethylene (HDPE) plants. The lack of sophisticated software support hinders the recurrent use of these techniques. This paper also presents userfriendly, easy to use, graphical user interface to raise the usability and accessibility of the approach of online update of the PLS models.
