Abstract:

An approach is proposed to solve the problem how to
obtain the priorities from interval fuzzy preference relations. Firstly,
another expression of interval numbers is given. Then, some basic
definitions on consistency and weak transitivity of real and interval
fuzzy preference relations are described. Based on these definitions,
a two-phase process for determining the priorities from
interval fuzzy preference relations is presented. Finally, two examples
are used to illustrate the use of the proposed approach.
