HYBRID NORM PRODUCT AND RELATION STRUCTURES IN HEMIRINGS
Проблемы анализа, 2023 In fuzzy logic, the triangular norm (𝑡- norm) is an operator that represents conjunctions. The concept of 𝑡- norm turned out to be a basic tool for probabilistic metric spaces, but also in several areas of mathematics, including fuzzy set theory, fuzzy

Multi-fuzzy Rough Sets based on Implicators and Continuous t-norms
Fuzzy Information and Engineering, 2017 This paper extends the study of multi-fuzzy rough sets using an implicator and a continuous t-norm and thus introduces multi-fuzzy rough sets based on fuzzy logical connectives.

Characterizations of Hyperrings by Fuzzy Hyperideals with Respect to A t-norm
Fuzzy Information and Engineering, 2017 In this paper, we inquire further into the properties on some kind fuzzy hyperideals and we study the hyperrings via T-fuzzy hyperideals. By means of the use of a triangular norm T, we define, characterize and study the T-fuzzy left and right hyperideals,

Ranking efficient DMUs using the Tchebycheff norm with fuzzy data in DEA [PDF]
International Journal of Research in Industrial Engineering, 2019 In many real applications, the data of production processes cannot be precisely measured. Hence the input and output of Decision Making Units (DMUs) in Data Envelopment Analysis (DEA) may be imprecise or fuzzy-numbered. In original DEA models, inputs and

IEEE Access, 2019 Fuzzy system, as the main method of approximate reasoning, has been widely used to solve practical problems. The existing results on fuzzy systems were based on fuzzy sets, fuzzy if-then rule, and fuzzy inference.

Le Matematiche, 2012 By using vague sets we generalize the notion of convex sets and introduce the notion of (α, β ,T )-convex vague sets and study their properties, where T is a triangular norm on [0, 1].

Formal Ordinal Sums of Triangular Norms on Modular Lattices
MathematicsThe formal ordinal sums of t-norms on the bounded lattice is defined by Saminger, but the formal ordinal sum need not be a t-norm. Hence, she provides a necessary and sufficient condition such that the formal ordinal sum is a t-norm indeed. In this paper,

Study on Sugeno Probability Integral of γ-fuzzy Operator
Journal of Harbin University of Science and Technology, 2020 As an indispensable branch of fuzzy mathematics, fuzzy probability integral is an important integral form that relies on fuzzy probability and fuzzy measure, and is also a powerful tool for studying fuzzy mathematics. Aiming at the definition and theorem
