Dynamic Graphical Presentation of High Dimensional Data
for Use in Process Control
William F. Eddy
We describe the current state of a continuing project which addresses
control of one aspect of a particular batch-continuous manufacturing
process. Previous spatial time series modelling for this aspect of
the process has been based on traditional nonparametric modeling
techniques (a kernel-based smoothing procedure, in particular). Here
we describe a substantially refined semi-parametric model. This model
incorporates basic physical knowledge about this aspect of the process
in the form of a coupled system of partial differential equations.
The manuscript is accompanied by a video tape showing some of the data and
the fitted models.
