With the generalisation of intuitionistic fuzzy sets (IFSs), picture fuzzy sets (PFSs) have been
developed based on membership, neutral membership, and non-membership degrees …

We present a communication which deals with some new methods to solve multiple attribute
decision-making (MADM) problems based on Pythagorean neutrosophic normal interval …

Pythagorean fuzzy sets have a lot of applications in the field of engineering and scientific
problems. Also, besides, the power averaging (PA) operator can reduce the influence of …

This article introduces the structure of the (t, s)-regulated interval-valued neutrosophic soft
set (abbr.(t, s)-INSS). The structure of (t, s)-INSS is shown to be capable of handling the …

Bipolar fuzzy sets (BFSs) are effective tool for dealing with bipolarity and fuzziness. The sine
trigonometric functions having two significant features, namely, periodicity and symmetry …

The failure mode and effects analysis (FMEA) is an important tool for risk assessment, which
can identify and eliminate potential failure modes in a system. However, due to the inherent …

The complexity of multi-criteria decision-making (MCDM) makes it challenging for decision-
makers (DMs) to reach an optimal decision. Therefore, this study sought to develop a novel …

Smarandache developed the idea of hypersoft set (HSS) theory as an extension of soft set
(SS) theory. HSS provides a general mathematical framework for handling data that can be …

Kolkata city is the capital of West Bengal, India. Due to improper administration, this city has
long been plagued by a drinking water shortage. The rapid urbanisation and population …

In this article, the notion of interval-valued preinvex functions involving the Riemann–
Liouville fractional integral is described. By applying this, some new refinements of the …
