production system
<programming> A production system consists of a collection of productions
(rules), a working memory of facts and an algorithm, known as forward chaining,
for producing new facts from old. A rule becomes eligible to "fire" when its
conditions match some set of elements currently in working memory. A conflict
resolution strategy determines which of several eligible rules (the conflict
set) fires next. A condition is a list of symbols which represent constants,
which must be matched exactly; variables which bind to the thing they match and
"<> symbol" which matches a field not equal to symbol.
Example production systems are OPS5, CLIPS, flex.
