Talk:Robustness

Untitled
The article presently under robustness is improper. Robustness is more related to a system's ability to reject disturbances. It is a term frequently used in control

Please elaborate on these topics.

Robustness of Systems span three properties
In English, the definitions of resilience and robustness, and their synonyms, appear to outline three broad strategies (broadly could be classed as 1. elasticity, 2. toughness and 3. adaptiveness), which are adopted by [something] to face and to overcome stress. In systems science, class one is stability. In complexity science where systems are in dynamic balance far from equilibrium (a point where stability occurs), class 2 refers to systems that tip between states after their tolerances are exceeded. Only class 3 can be described as robust in complexity science because they sustain or regain overall function under a situation of changed form. Class 3 entities or systems possess class 2 as a diverse trait, in which greater diversity of 'toughness' enables systems to be robust and underpins initial survival of a sub-population under selective pressures or stress and adaptation (class 3). Where there is less diversity in 'toughness' systems can be defined as brittle, as state changes may result in extinction. As such this article is inaccurate and does not cover robustness, as the definition it opens with is for elastic or class 1, which is Stability. It also does not move beyond class 2 definitions.

The definitions should describe [something] that possesses an inherent or acquired process or ability (eg strength, power) that can sufficiently absorb experienced stress and either sustain during, or recover after, function (at minimum) or both form and function (at most).

The process can be passive or proactive, applying to past, current and future (predicted) stress, but also different levels of experienced stress (eg. from the everyday, severe, devastating, catastrophic...).

Elasticity (to readily give/go with stress and actively return to a previous state (form and function) following stress) [Synonyms: stability, flexible, plastic, supple, bouncy, rubbery, pliable, springy]:

1. to absorb and give/go with [stress] 2. to spring back / to bounce back / to return to / to recover 3. to rebuild (deliberate intent)

Toughness (level of disturbance that can be absorbed before a system transforms state (form and function) - or - to withstand [stress] by actively absorbing it within a tolerance or threshold without transforming state (form and function)... ) [Synonyms: endure / endurance / tough / durable / lasting / resistant / hardy / sturdy / sturdily / strapping / dependable / reliable / substantial / stauch / hardened]:

1. to cope / to get through (to navigate and utilize effective methods to overcome) 2. to absorb by... to resist / to withstand / to work-against / to persist / to overcome

Adaptiveness (to change state (form and function) readily in order to regain or sustain successful function (but not form) in changed circumstances [stress]...) [Synonym: robustness]:

1. to improve (deliberate intent) 2. to learn (agency) 3. to change (or be changed) / to adjust / to fit / to become (successful) again

Synonyms of Stress:
