Weller School of Science and Technology, University of Teesside, Middlesbrough, Cleveland TS1 3BA, UK ABSTRACT ALEXSYS, a prototype expert system was designed for use in the aluminium high pressure die-casting industry. The aim of the system was to reduce wastage within the industry, which accounts for a considerable sum annually. The system was divided into two separate components, the Adviser and the Predictor system, one to offer advice regarding dies already in production and the other to offer optimum values for dies in the design stage.
