Abstract

We present the analysis, design and implementation of a knowledge based operator guidance system (OGS) in the coal washing domain. AshMod integrates the KADS methodology for the development of knowledge based systems with the G2 real time implementation environment. It assists the operator in monitoring the plant, performing fault diagnosis, and in plant optimisation. With the decision support provided by AshMod, the operator is able to control the amount of ash (impurity) in clean coal, hence increasing plant productivity. One of our goals in developing AshMod was to implement a high quality knowledge based system that would assist
