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.

FILTRATION 1)2)

"The selection of a subset for transmission to a receiver, from the set of messages intended for him" (R. ACKOFF & F.E. EMERY, 1972, p.191).

ACKOFF and EMERY add: "An intermediary may filter messages with the intention of better serving the receiver's purpose, as in transmitting only messages that he believes are of value to the receiver. Or the intermediary may filter for its own or another party's purposes. When it does so, it engages in censorship" (Ibid).

In fact, the concept of filtration is much more general that this. Any complex system is preconditioned to admit only useful inputs from its environment and use numerous filtration devices to protect itself.

From a different viewpoint, as observed by D. DUBOIS, any modelization implies selectively filtering out properties of the concrete system.

"Any model is constructed by reference to a particular scale of the system, without taking in account the details on the lesser levels. Only some properties of these lesser levels are considered" (1990, p.75).
