Context and Background: Complex fuzzy theory has a strong practical implication in many
real-world applications. Complex Fuzzy Inference System (CFIS) is a powerful technique to …

A hesitant fuzzy set is a significant tool to model disagreements of the decision-makers over
a subject. Also, the notion of the soft set is another useful instrument in the modelling of …

The multi-criteria decision-making (MCDM) field has long sought tools capable of adeptly
capturing the intricacies of human decision-making amidst uncertainty. Hesitant fuzzy sets …

Probabilistic hesitant fuzzy sets (PHFSs), a significant expansion of hesitant fuzzy sets
(HFSs), were suggested and intensively explored in order to address the problem of missing …

Interval-valued fuzzy soft set-based decision making and the related parameter reduction
algorithms were proposed. However, up to the present, few documents have focused the …

Abstract Molodtsov (Comput Math Appl 37: 19–31, 1999) introduced the concept of soft set
as a new mathematical tool for dealing with uncertainties that is free from the difficulties that …

Soft set is one of the latest mathematical models to handle uncertainty. In a soft set, every
element of its parameter set is associated with a subset of the universe of discourse under …

As seed selection is a challenging task due to the presence of hundreds of varieties of seeds
of each kind, some homework is necessary for selecting suitable seeds as new varieties and …

Decision making has become a common feature in day-to-day activities. Uncertainty-based
models are more efficient in handling such problems. In this chapter, we propose an …

There are several models of uncertainty found in the literature like fuzzy set (FS), rough set,
intuitionistic fuzzy set, soft set, and hesitant fuzzy set. Also, several hybrid models have come …
