A “system", therefore, has implicit as well as explicit definition of boundaries to which the systematic process of hazard identification, hazard analysis and control is applied. The system can range in complexity from a crewed spacecraft to an autonomous machine tool. The system safety concept helps the system designer(s) to model, analyse ...
Software safety (sometimes called software system safety) is an engineering discipline that aims to ensure that software, which is used in safety-related systems (i.e. safety-related software), does not contribute to any hazards such a system might pose. There are numerous standards that govern the way how safety-related software should be ...
Safety engineering is an engineering discipline which assures that engineered systems provide acceptable levels of safety. It is strongly related to industrial engineering/systems engineering, and the subset system safety engineering. Safety engineering assures that a life-critical system behaves as needed, even when components fail.
Revision B was released in August 2024 in coordination with a number of rules changes addressing aircraft system safety. This release is a significant expansion, elaborating on the FAA's Fail-Safe Design Concept and crystalizing and harmonizing FAA system safety terminology, such as the intent of “Extremely Improbable.”
The correspondence between the kind of property (safety vs liveness) with kind of proof (invariance vs well-foundedness) was a strong argument that the decomposition of properties into safety and liveness (as opposed to some other partitioning) was a useful one—knowing the type of property to be proved dictated the type of proof that is required.
All phases are concerned with the safety function of the system. The standard has seven parts: Parts 1–3 contain the requirements of the standard (normative) Part 4 contains definitions; Parts 5–7 are guidelines and examples for development and thus informative. Central to the standard are the concepts of probabilistic risk for each safety ...
A safety-critical system [2] or life-critical system is a system whose failure or malfunction may result in one (or more) of the following outcomes: [3] [4] death or serious injury to people; loss or severe damage to equipment/property; environmental harm
Functional safety is the part of the overall safety of a system or piece of equipment that depends on automatic protection operating correctly in response to its inputs or failure in a predictable manner ().
