Concurrent events risk assessment generic models with enhanced reliability using Fault tree analysis and expanded rotational fuzzy sets

作者：

Highlights：

• Generic risk assessment models to estimate combined influence of concurrent risks.

• Generic & inclusive risk breakdown structure to avoid overseeing influential risks.

• Logic gates to avoid accumulating of dependent, redundant, & non-concurrent risks.

• Effectiveness of safety measures are accounted for to produce residual risk value.

• Enhanced gradation of fuzzy truth values to reduces rounding and misrepresentation.
