CORE DEFINITION

The ability of a system to maintain its functions when subjected to disturbances, errors, or parameter variations. Unlike "antifragility" (which benefits from chaos), robustness is about being "tough".

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Fault-tolerant foundation. When designing, do not pursue extreme precision (that is fragile), but rather "good enough to run". Leave margin in the system so it can withstand stress.

anchor

Anchor fast decisions

Robustness (also translated as robustness) refers to the ability of a system, model, or control to maintain expected functions in the face of disturbances, abnormal inputs, or parameter fluctuations. It measures "toughness" rather than "optimal under ideal conditions".
