[EN] This paper explores the advancements in soft sets and their extensions, contributing to the evolving field of soft computing. Soft sets, introduced by Molodtsov, provide a flexible framework for handling uncertainty and imprecision in decision-making processes. The research delves into various extensions of soft sets, including hybrid models with other mathematical structures, enhancing their applicability in diverse domains. Novel methodologies for parameterization and optimization within soft sets are investigated, aiming to improve their efficiency and effectiveness in real-world applications. The study emphasizes the integration of soft sets with machine learning techniques, fostering the development of intelligent systems capable of handling complex and uncertain information. The findings showcase the versatility and potential of soft sets and their extensions, opening new avenues for future research in this dynamic field.

The abundant growth of variations in intuitionistic fuzzy sets has posed a challenge in assessing the characteristics of diverse decision-making models. In this context, we will delve into the subject within the context of interval-valued intuitionistic fuzzy sets. Our work has a dual purpose. On a theoretical plane, we establish two theorems that facilitate the conversion of interval-valued intuitionistic fuzzy sets into appropriately correlated pairs of intuitionistic fuzzy sets. On a more pragmatic note, we illustrate how these findings can be harnessed to amalgamate interval-valued intuitionistic fuzzy sets and applied to the collective decision-making process within this framework.

We delve into the application of two operational transformation techniques that represent a single interval-valued intuitionistic fuzzy number using two intuitionistic fuzzy numbers in a constructive fashion. These techniques are employed to achieve seamless aggregation of interval-valued intuitionistic fuzzy numbers and facilitate multi-attribute decision-making within this framework. The decision-making and prioritization processes rely on comparison laws that consider the score and accuracy of an interval-valued intuitionistic fuzzy number. We illustrate how these parameters can be derived from the analogous proxies associated with the intuitionistic fuzzy numbers that represent it. To wrap up our exploration, we present a comparative study as the culmination of this research endeavor.

[EN]Under uncertainty, traditional sets may not be sufficient to represent real-world phenomena, and fuzzy sets can provide a more flexible and natural approach. The concept of fuzzy sets has been widely used in various fields, including artificial intelligence, control theory, decision-making, and pattern recognition. Fuzzy sets can also be combined with other mathematical tools, such as probability theory, to provide a more comprehensive approach to uncertainty management. In these notes, we explore the concept of fuzzy sets under uncertainty, and their applications in various fields. We discuss the fundamental concepts of fuzzy sets, including fuzzy membership functions, fuzzy operations, and fuzzy relations. We also examine different types of uncertainty, including epistemic and aleatory uncertainty, and how fuzzy sets can be used to model and manage uncertainty in these cases.

[ES]Muchos problemas en los campos de la economía, la informática, la medicina, el medio ambiente y otras ciencias conllevan incertidumbre, imprecisión o subjetividad. Introducida por Molodtsov, la teoría de los soft sets ha demostrado su aplicabilidad a diversos campos. Fatimah et al. proponen el modelo de soft sets ampliado que denominan N-soft sets. Debido a la importancia de las calificaciones en situaciones del mundo real, los N-soft sets introducen descripciones parametrizadas del universo de opciones que dependen de un nu ́mero finito de calificaciones.

[ES]Muchos problemas de la vida real requieren el uso de datos imprecisos o inciertos. Su análisis debe implicar la aplicación de principios matemáticos capaces de captar estas características. La teoría de los conjuntos difusos supuso un cambio paradigmático en las Matemáticas al permitir la pertenencia parcial. Para una definición y argumentos acerca de su aplicabilidad a varios campos, nos interesa especialmente una generalización de los conjuntos difusos: la aplicación de la teoría de los soft sets y sus extensiones a los problemas de toma de decisiones.
