production system
(foldoc) | production system
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.

CLIPS
(CLIPS) A language produced by Gary Riley of NASA
JSC in Houston, Texas, for developing expert systems, with
the inferencing and representation capabilities of OPS5 and
support for forward chaining rule-based, object-oriented
and procedural programming. CLIPS has a Lisp-like
syntax. It is available for MS-DOS and comes with source
code in C.
COSMIC, U Georgia, (404) 542-3265. Austin Code Works

Versions include CLIPS 5.1, CLIPS/Ada 4.3 and CLIPS6.0 (see
PCLIPS).

official production system
(foldoc) | Official Production System
(OPS) The first production system (i.e. rule
based) programming language, developed at CMU in 1970 and
used for building expert systems. OPS was originally
written in Franz Lisp and later ported to other LISP
dialects.
