This paper presents two novel interval-valued fuzzy soft set approaches. First, we initiate a
new axiomatic definition of interval-valued fuzzy distance measure, which is expressed by …

This paper aims to give deeper insights into decision making problem based on interval-
valued fuzzy soft set (IVFSS). Firstly, a new score function for interval-valued fuzzy number is …

In a typical formulation of decision-making under uncertainty, a decision-maker must choose
a single-optimal option among many possible options. However, the problem of selecting a …

Interval-valued intuitionistic fuzzy (IVIF) soft set is one of the useful extensions of the fuzzy
soft set which efficiently deals with the uncertain data for the decision-making processes. In …

In this work, we introduce the concept of fuzzy parameterized intervalvalued fuzzy soft set
theory (fpivfss) and study their operations. We then define fpivfss-aggregation operator to …

The soft set theory, originally proposed by Molodtsov, can be used as a general
mathematical tool for dealing with uncertainty. The interval-valued intuitionistic fuzzy soft set …

There has been a rapid growth of interest in developing approaches that are capable of
dealing with imprecision and uncertainty. To this end, an interval-valued fuzzy soft set …

Molodtsov's soft set theory was originally proposed as a general mathematical tool for
dealing with uncertainty. Research on (fuzzy) soft set based decision making has received …

An interval-valued picture fuzzy set (IVPFS) is one of the generalizations of an interval-
valued fuzzy set to handle the uncertainties in the data during analysis. The aim of this paper …

Soft set theory is a newly emerging mathematical tool to deal with uncertain problems. Since
the trapezoidal fuzzy number, as a vital concept of fuzzy set, can express linguistic …
