“…Internally, KBS systems consist of two principle components: a knowledge base (KB), or knowledge bases; and an inferencing engine. KBs contain a structured representation of accumulated knowledge about the chosen problem (Davis, 1986;Greenwell, 1988) in the form of parameters, databases and rulebases (Laut, 1993). Databases may either be stored locally on the computer running the KBS or accessed from a remote source and, where data are dynamic (for example, meteorological information), may take the form of computer simulations (Harbans et al, 1987).…”
