Interval-Valued Fuzzy Parameterized Intuitionistic Fuzzy Soft Sets and Their Applications
Abstract
In recent years, the fuzzy sets, interval-valued fuzzy
sets, intuitionistic fuzzy sets and soft sets, which offer different
perspectives for the structures containing the uncertainties, have attracted
the interest of many researchers. Also, the intuitionistic fuzzy soft sets
produced by combining the intuitionistic fuzzy sets with the soft sets have
been widely studied. In this work, the concept of interval-valued fuzzy
parameterized intuitionistic fuzzy soft set (IVFPIFS set) is introduced. This
set is the generalization of soft sets, fuzzy soft sets, fuzzy parameterized
(fuzzy) soft sets, interval-valued fuzzy parameterized (fuzzy) soft sets,
intuitionistic fuzzy soft sets and fuzzy parameterized intuitionistic fuzzy
soft sets. For the IVFPIFS sets, basic operations such as complement, union and
intersection are defined. Also, the
properties of these operations are investigated in detail. Lastly, an algorithm
by using the aggregation operators based on the IVFPIFS sets is constructed.
The examples are given to verify the feasibility and validity of the proposed
algorithm.
