单词 robustness
释义
robustness

Computer
  • A measure of the ability of a system to recover from error conditions, whether generated externally or internally; for example, a robust system would be tolerant to errors in input data or to failures of internal components. Although there may be a relationship between robustness and reliability, the two are distinct measures: a system never called upon to recover from error conditions may be reliable without being robust; a highly robust system that recovers and continues to operate despite numerous error conditions may still be regarded as unreliable in that it fails to provide essential services in a timely fashion on demand.


Electronics and Electrical Engineering
  • The ability of a system to function correctly in the presence of faults, whether these are internal defects or errors of input. In computer-based systems the term also refers to a system’s ability to cope with programming errors in its own code. Adaptive systems are an approach to having robustness when the inputs or environment behave in an unanticipated fashion.
