The aim of this paper is to develop a method for ranking trapezoidal intuitionistic fuzzy numbers (TrIFNs) in the process of decision making in the intuitionistic fuzzy environment. Firstly, the concept of TrIFNs is introduced. Arithmetic operations and cut sets over TrIFNs are investigated. Then, the values and ambiguities of the membership degree and the nonmembership degree for TrIFNs are de...

In order to provision content-based services to their users, service providers need to purchase content distribution rights from various content providers. Sometimes the creation phase of certain content categories can last longer than planed so content providers deliver the content to service providers with delays. The delayed delivery can cause financial damages and inconveniences to service ...

The Pythagorean fuzzy soft set (PFSS) is the most proficient and manipulative leeway of (PFS), which contracts with parameterized values alternatives. It a generalized form intuitionistic (IFSS), provides healthier more accurate evaluations through decision-making (DM). main determination this research to prolong idea Einstein’s aggregation operators for PFSS. We introduce Einstein operational ...

We consider the multiattribute decision-making problem under risk with partial information of the decision-makers’ preferences modelled through an imprecise vectorial utility function and where the consequences are assumed under uncertainty. In this framework under imprecision, we introduce the appropriate utility efficient set that plays a fundamental role because it is where the decision-make...

The paper deals with a complex decision-making problem, the selection and evaluation of Learning Management Systems (LMS) in which several objectives referring to the definite group of users like social, technical, environmental, and economic impacts, must be simultaneously taken into account. We introduce Evaluation Cycle Management (ECM), a support methodology aimed at the evaluation of optio...

The simplified neutrosophic set (SNS) is a useful generalization of the fuzzy set that is designed for some practical situations in which each element has different truth membership function, indeterminacy membership function and falsity membership function. In this paper, we develop a series of power aggregation operators called simplified neutrosophic number power weighted averaging (SNNPWA) ...
