production system

(programming)A production system consists of a collection ofproductions (rules), a working memory of facts and analgorithm, known as forward chaining, for producing newfacts from old. A rule becomes eligible to "fire" when itsconditions match some set of elements currently in workingmemory. A conflict resolution strategy determines which ofseveral eligible rules (the conflict set) fires next. Acondition is a list of symbols which represent constants,which must be matched exactly; variables which bind to thething they match and "<> symbol" which matches a field notequal to symbol.

Example production systems are OPS5, CLIPS, flex.
