Intuitionistic fuzzy PRI-AND and PRI-OR aggregation operators

In this paper, we investigate the multi-attribute decision making (MADM) problem under Atanassov's intuitionistic fuzzy environment in which the attributes are in different priority levels. We develop the intuitionistic fuzzy prioritized and operator and intuitionistic fuzzy prioritized or operator, which are motivated by the idea of Yager's prioritized and operator and prioritized or operator. These intuitionistic fuzzy prioritized aggregation operators can be applied to aggregate intuitionistic fuzzy information when the attributes are in different priority levels. A practical example is used to illustrate the applicability and effectiveness of the proposed intuitionistic fuzzy prioritized or operator. (c) 2012 Elsevier B.V. All rights reserved.
