A basic review of fuzzy logic applications in hydrology and water resources

open access: yesApplied Water Science, 2020
In recent years, fuzzy logic has emerged as a powerful technique in the analysis of hydrologic components and decision making in water resources. Problems related to hydrology often deal with imprecision and vagueness, which can be very well handled by ...

Fuzzy inequational logic [PDF]

open access: yesInternational Journal of Approximate Reasoning, 2015
We present a logic for reasoning about graded inequalities which generalizes the ordinary inequational logic used in universal algebra. The logic deals with atomic predicate formulas of the form of inequalities between terms and formalizes their semantic

On the prediction of Covid-19 time series: an intuitionistic fuzzy logic approach [PDF]

open access: yesJournal of Fuzzy Extension and Applications, 2021
This paper presents a time series analysis of a novel coronavirus, COVID-19, discovered in China in December 2019 using intuitionistic fuzzy logic system with neural network learning capability. Fuzzy logic systems are known to be universal approximation

Sustainable Closed-Loop Supply Chain Design Problem: A Hybrid Genetic Algorithm Approach

open access: yesMathematics, 2020
In this paper, we propose a solution to the sustainable closed-loop supply chain (SCLSC) design problem. Three factors (economic, environmental, and social) are considered for the problem and the three following requirements are addressed while ...

Archimedean-Compensatory Fuzzy Logic Systems [PDF]

open access: yesInternational Journal of Computational Intelligence Systems, 2015
The paper aims to define a new kind of logic, referred to as Archimedean-Compensatory Logic, which is constructed from the unification of two different fuzzy logic systems, namely a continuous Archimedean fuzzy logic and a compensatory fuzzy logic.
