In this paper, we introduce an axiomatic definition of an interval-valued fuzzy sets' inclusion measure which is different from Bustince's [H. Bustince, Indicator of inclusion grade for… Expand

Weighted triangular approximation of fuzzy numbers

- Wenyi Zeng, H. Li
- Mathematics, Computer Science
- Int. J. Approx. Reason.
