The Department of Automatic Control is responsible for the development
of a operator procedure
handling toolbox that will be used to support the operators in process
state transitions. The toolbox
is based on Grafchart, a G2 based toolbox for supervisory level sequence
and procedure handling and
JGrafchart, a new Java based
version of Grafchart.
We are also investigating the possibility to use numerical optimization
techniques for grade change sequence generation.
