felkorridor
Felkorridor is a term that appears in Swedish-language engineering and risk literature, translating roughly to “error corridor” or “fault corridor.” In general, it refers to a defined range of operational conditions or parameter values in which a system exhibits degraded performance or errors but remains functional, as opposed to regions of nominal operation or complete failure. The concept helps analyze resilience and tolerance to disturbances by identifying margins between normal operation and fault states. Etymology: fel meaning fault or error, korridor meaning corridor.
Usage and interpretation can vary by domain. In control systems, felkorridor may denote the set of state-space
Relation to similar concepts: It overlaps with margin of safety, fault tolerance, tolerance bands, and degradation
See also: margin of safety, fault tolerance, resilience engineering, diagnostic thresholds.
Notes: Because felkorridor is not a widely standardized term, its precise definition and scope should be checked
