Due to the diversity of information, many decision-making problems cannot be solved based
on a single criterion. The complexity of assessment objects and the limitations of individual …

Multi criteria decision making (MCDM) is a discipline of operations research which has
widely studied by researchers and practitioners. It deals with evaluating and ranking …

Interval-valued fuzzy sets have been developed and applied to multiple criteria analysis.
However, the influence of optimism and pessimism on subjective judgments and the …

Interval-valued fuzzy sets involve more uncertainties than ordinary fuzzy sets and can be
used to capture imprecise or uncertain decision information in fields that require multiple …

The theory of interval valued fuzzy sets is very valuable for modeling impressions of decision
makers. In addition, it gives ability to quantify the ambiguous nature of subjective judgments …

In the past, lots of multi-criteria decision-making (MCDM) methods included simple additive
weighting (SAW) extended under fuzzy environment into multi-criteria decision-making …

Decision making is the process of finding the best option among the feasible alternatives. In
classical multiple-criteria decision-making (MCDM) methods, the ratings and the weights of …

In multiple attribute decision-making problems, many interval number ranking methods do
not focus on interval numbers that include non-positive ones and cannot represent decision …

In this paper, we investigate the multiple attribute group decision making (MAGDM)
problems, of which the attribute values in the group decision matrices provided by each …

Interval type-2 fuzzy set (IT2FS) offers interesting avenue to handle high order information
and uncertainty in decision support system (DSS) when dealing with both extrinsic and …
