  2. Failure mode, effects, and criticality analysis - Wikipedia

    en.wikipedia.org/wiki/Failure_Mode,_Effects,_and...

    Failure Modes, effects, and Criticality Analysis is an excellent hazard analysis and risk assessment tool, but it suffers from other limitations. This alternative does not consider combined failures or typically include software and human interaction considerations. It also usually provides an optimistic estimate of reliability.

  3. Failure mode and effects analysis - Wikipedia

    en.wikipedia.org/wiki/Failure_mode_and_effects...

    Failure mode and effects analysis (FMEA; often written with "failure modes" in plural) is the process of reviewing as many components, assemblies, and subsystems as possible to identify potential failure modes in a system and their causes and effects. For each component, the failure modes and their resulting effects on the rest of the system ...

    There are several methodologies that can be used to conduct a PHA, including checklists, hazard identification (HAZID) reviews, what-if reviews and SWIFT, hazard and operability studies (HAZOP), failure mode and effect analysis (FMEA), etc. PHA methods are qualitative or, at best, semi-quantitative in nature.

  5. Failure modes, effects, and diagnostic analysis - Wikipedia

    en.wikipedia.org/wiki/Failure_Modes,_Effects...

    A design failure modes and effects analysis, DFMEA, is a structured qualitative analysis of a system, subsystem, device design to identify potential failure modes and their effects on correct operation. The concept and practice of performing a DFMEA, has been around in some form since the 1960s.

  6. Hazard analysis - Wikipedia

    en.wikipedia.org/wiki/Hazard_analysis

    When used as part of an aviation hazard analysis, a "Likelihood" is a specific probability. It is the joint probability of a hazard occurring, that hazard causing or contributing to an aircraft accident or incident, and the resulting degree of loss or harm falling within one of the defined severity categories.

  7. Fault tree analysis - Wikipedia

    en.wikipedia.org/wiki/Fault_tree_analysis

    A fault tree diagram. Fault tree analysis (FTA) is a type of failure analysis in which an undesired state of a system is examined. This analysis method is mainly used in safety engineering and reliability engineering to understand how systems can fail, to identify the best ways to reduce risk and to determine (or get a feeling for) event rates of a safety accident or a particular system level ...

    The Zonal Safety Analysis (ZSA) looks at each compartment on the aircraft and looks for hazards that can affect every component in that compartment, such as loss of cooling air or a fluid line bursting. The Common Mode Analysis (CMA) looks at the redundant critical components to find failure modes which can cause all to fail at about the same time.

  9. Hazard analysis and critical control points - Wikipedia

    en.wikipedia.org/wiki/Hazard_analysis_and...

    Hazard analysis and critical control points, or HACCP (/ ˈ h æ s ʌ p / [1]), is a systematic preventive approach to food safety from biological, chemical, and physical hazards in production processes that can cause the finished product to be unsafe and designs measures to reduce these risks to a safe level. In this manner, HACCP attempts to ...
