Risk prioritization in Failure Mode and Effects Analysis using interval type-2 fuzzy sets

作者：

Highlights：

• A new fuzzy FMEA approach based on IT2 fuzzy sets is proposed.

• The approach introduces a new aggregation method.

• The approach utilizes an α-cut based aggregation operator for the first time.

• The approach introduces a practical method for ranking overall priority values.

• Comparisons show that the approach provides a satisfactory modeling of uncertainty.
