On Uncertainty Measures of the Interval-Valued Hesitant Fuzzy Set

Interval-valued hesitant fuzzy sets (IVHFS), as a kind of decision information presenting tool which is more complicated and scientific elastic, have an important practical value in multiattribute decision-making. There little research on the uncertainty IVHFS. The existing measure cannot distinguish different IVHFS some contexts. In my opinion, for IVHFS, there should exist two types uncertainty: one fuzziness other nonspecificity To best our knowledge, index to all are single indexes, could not consider facets First, review given entropy interval-valued set, fact that circumstances pointed out. With regard measures we propose two-tuple it. One used method construct also given. proposed can make up fault set’s measure.
