Abstract Evaluation and selection problems are becoming increasingly difficult due to
human judgment and unknown evaluation risks. These circumstances mean that contractor …

To handle uncertain information where opinion has more than two aspects, the frame of T-
spherical fuzzy (TSF) set is of significance. The goal of this paper is to introduce some …

In this article, a novel CoCoSo (Combined compromise solution) method based on Frank
operational laws and softmax function is investigated to handle multiple attribute group …

The technology deployment in smart e-tourism brings high potential in terms of customer
data, events, reservations, and others. It acts as an effective and personalized guide to aid …

In this manuscript, the technique of the generalized MULTIMOORA method is investigated
by using the concept of a T‐spherical fuzzy set (T‐SFS), which is the modified idea of a …

A contribution of this article is to introduce new q-rung Orthopair fuzzy (q-ROF) aggregation
operators (AOs) as the consequence of Aczel–Alsina (AA) t-norm (TN)(AATN) and t-conorm …

Spherical fuzzy sets are an extension of various fuzzy concepts and demonstrate fuzzy
opinion using membership, abstinence, nonmembership and refusal degrees with relaxed …

To handle problematic and ambiguous data, Schweizer and Sklar added a parameter p in
1960, which helped to develop the theory of SS t-norm (SSTN) and t-conorm (SSTCN). The …

To handle complex, risk-illustrating, and asymmetric information, the theory discussed in this
analysis is much more suitable for evaluating the above dilemmas. To manage ambiguity …

The green supplier selection is one of the popular multiple attribute group decision making
(MAGDM) problems. The spherical fuzzy sets (SFSs) can fully express the complexity and …
