System fault diagnostics using fault tree analysis

Institutional Repository System fault diagnostics using fault tree analysis

Over the last 50 years advances in technology have led to an increase in the complexity and sophistication of systems. More complex systems can be harder to maintain and the root cause of a fault more difficult to isolate. Down-time resulting from a system failure can be dangerous or expensive depending on the type of system. In aircraft systems the ability to quickly diagnose the causes of a f...

Integrated system fault diagnostics utilising digraph and fault tree-based approaches

Fault Tree Analysis

Since its founding, NASA has been dedicated to the advancement of aeronautics and space science. The NASA Scientific and Technical Information (STI) Program Office plays a key part in helping NASA maintain this important role. The NASA STI Program Office is operated by Langley Research Center, the lead center for NASA's scientific and technical information. The NASA STI Program Office provides ...

Verifying Formal Specifications Using Fault Tree Analysis∗

Specification before implementation has been suggested as a sensible approach to software evolution. The quality of this approach may be improved by using formal specification. However, to serve as a trustable foundation for implementation and to help reduce the cost in program testing, the formal specification must be ensured to be satisfiable, consistent, complete, and accurate in recording t...

Public transport risk assessment through fault tree analysis

This study focused on the public transport risk assessment in District one of ​​Tehran through Fault Tree Analysis involving the three criteria of human, vehicle and road in Haddon matrix. In fact, it examined the factors contributing to the occurrence of road accidents at several urban black spots within District 1. Relying on road safety checklists and survey of experts, this study made an ef...
