An expert system contains a number

An expert system contains a number of rules to be followed. The rules are interconnected; the number of outcomes is known in advance and is limited; there are multiple paths to the same outcome; and the system can consider multiple rules at a single time. The rules illustrated are for simple credit-granting expert systems.

An inference engine works by searching through the rules and “firing” those rules that are triggered by facts gathered and entered
by the user. Basically, a collection of rules is similar to a series of nested IF statements in a traditional software program; however,
the magnitude of the statements and degree of nesting are much greater in an expert system.
