Many structural systems are subjected to the risk of cascading system-level failures initiated by local failures. For efficient reliability analysis of such complex system problems, many research efforts have been made to identify critical failure sequences with significant likelihoods by an event-tree search coupled with system reliability analyses; however, this approach is time-consuming or ...

Background and Aim : Emergency ward is among hospital areas with high risk of errors, thus, implementing measures to identify and correct the errors is essential. The object of this study is to identify and assess the errors of the process of admitting patients in Emergency Department of Imam Reza Hospital using Failure Mode Effects Analysis, as one of the tools to assess and manage risk, as we...

Communicating failure mode information during design and manufacturing is a crucial task for failure prevention. Most processes use Failure Modes and Effects types of analyses, as well as prior knowledge and experience, to determine the potential modes of failures a product might encounter during its lifetime. When new products are being considered and designed, this knowledge and information i...

A failure mode and effect analysis (FMEA) was applied to improve the design of concrete ties in ballasted track for North American heavy haul applications. A literature review was conducted on concrete tie failure modes, failure effects, and failure causes. A survey of railroads and transit authorities in North America provided a ranking of the most critical concrete tie failure modes. The most...

Sensitivity analysis identifies the influential parameters and it is a key step in design process. Focusing on reliability based design, probability of failure mode its sensitivity to input uncertainties are obtained single Monte Carlo simulation using Likelihood Ratio method. For correlated multiple modes, matrix proposed. The dominant singular vectors found indicate most important for combine...
