In this paper, the measures taken to enhance the performance of the filtration operation by allowing the operator to make more and better informed decisions through the implementation of an Intelligent Advisory System in the Alcoa of Australia Ltd Wagerup Alumina refinery are discussed. The G2 expert system (Gensym Corp.) has been used to implement a knowledge-based operator guidance system that not only relies on past experience via sets of rules, but also enables several possible operating scenarios to be evaluated using a mathematical cost function. It then provides operators with the best solution to a particular process problem.
