“…Peres, Guerra, Alique and Ros (1999) also developed fuzzy control model for milling process optimisation and Vagelatos, Rigatos, and Tzafestas (2001) developed fuzzy control model for optimising the injection molding process. Other applications include optimisation of power distribution system operations that was developed by Sarfi and Solo (2002), food frying process (Rywotycki, 2003) and fuzzy expert control for oil and gas supplies (Neuroth, McConnell, Stronach, & Vamplew, 2000). Despite the wide application of fuzzy expert system, the technique has yet to be applied in the crude palm oil production.…”
