Within the EU/GROWTH project CHEM aimed at developing advanced decision support systems for the process industry, Grafchart, a toolbox for procedure handling based on Grafcet/Sequential Function Charts, will be used to implement a state-transition support toolbox. A brief overview of Grafchart is given, including a new Java version, JGrafchart. Operator support applications where Grafchart has been used are described.
