International Encyclopedia of Systems and Cybernetics

2nd Edition, as published by Charles François 2004 Presented by the Bertalanffy Center for the Study of Systems Science Vienna for public access.

About

The International Encyclopedia of Systems and Cybernetics was first edited and published by the system scientist Charles François in 1997. The online version that is provided here was based on the 2nd edition in 2004. It was uploaded and gifted to the center by ASC president Michael Lissack in 2019; the BCSSS purchased the rights for the re-publication of this volume in 200?. In 2018, the original editor expressed his wish to pass on the stewardship over the maintenance and further development of the encyclopedia to the Bertalanffy Center. In the future, the BCSSS seeks to further develop the encyclopedia by open collaboration within the systems sciences. Until the center has found and been able to implement an adequate technical solution for this, the static website is made accessible for the benefit of public scholarship and education.

RULE (If – then) 2)

← Back

Any rule that establishes the conditions of a specific behavior, or various alternative ones.

M. BODEN states: "A rule may include several conditions in its IF-side and several actions in its Then-side) (1990, p.215). Commenting on an abstract drawing program (AARON), she states: "Abstract-AARON's If-Then rules may be fairly complex. Several aspects (not just one) of the current state of the drawing may have to be checked, before the program knows what to do next" (p.143).

If – then rules are used in what A.I. Workers call "production systems", notably expert systems. BODEN gives the example of an expert system for the detection of soybeans diseases, which includes an array of descriptors of various types: environmental ones; global plant ones; conditions of leafs, of stems, of fruit pods, of seeds and of roots. (p.184).

MARUYAMA's deviation-amplification processes in cybernetics are also based on If-then rules.
