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.

CONSTRAINT THRESHOLD 2)

← Back

The configuration in space and the instant in time where and when the behavior of a composite system suddenly changes.

P. COUSSOT and J.M. PIAU comment: "When the concentration of particles increases, the median size of the clusters increases and, suddenly, beyond a defined concentration, a global net of interactions appears, which connects the whole sample. This is a percolation phenomenon.

"The fluid possesses a constraint threshold hat represents the minimun constraint that must be applied to break the net and start flow" (1993, p.1086).

The concept is of great importance for the study of avalanches of snow or mud, heaps of semi -viscous materials, gels, pastes and doughs, etc., where such thresholds can readily be observed.

Constraint thresholds, as a rheological effect seems however to be quite a more general type of phenomenon and be akin to the concepts of catastrophe and bifurcation.

It would be interesting to research possible constraint thresholds in living and social systems.
