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.

PERTURBATION (Endogenous) 1)2)

← Back

Anomalous variation of one or various functions of the system, which endangers its correct working and in some cases it very survival.

Any homeostatic system possess the capability to fluctuate in between maxima and minima limits of stability, generally in order to adapt itself to variations of its environment. The fluctuations relate in most cases to one of the functions or subsystems.

However some fluctuations may cross some stability threshold of the system, not allowing any more a return to the steady state. If no other subsystem is able to compensate adequately this disequilibrium, the system is heading for destruction or, in some very exceptional cases, undergoes a very radical transformation (emergence process).

Endogenous perturbations are generally the final results of an accumulation of exogenous variations or perturbations. In some cases however, these are in turn a result of the systems actions. An example are cardio-vascular diseases, due at least partly to excessive smoking or inconvenient diet.
