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

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.

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 ...

Task Feasibility Maximization Using Model-Free Policy Search and Model-Based Whole-Body Control

open access: yesFrontiers in Robotics and AI, 2020
Producing feasible motions for highly redundant robots, such as humanoids, is a complicated and high-dimensional problem. Model-based whole-body control of such robots can generate complex dynamic behaviors through the simultaneous execution of multiple ...

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 ...

Substructural fuzzy logics

open access: yesJournal of Symbolic Logic, 2007
AbstractSubstructural fuzzy logics are substructural logics that are complete with respect to algebras whose lattice reduct is the real unit interval [0, 1]. In this paper, we introduce Uninorm logicULas Multiplicative additive intuitionistic linear logicMAILLextended with the prelinearity axiom((A → B) ∧ t) V ((B → A)∧ t).

Hybrid Cooperative Co-Evolution Algorithm for Uncertain Vehicle Scheduling

open access: yesIEEE Access, 2018
As a typical scheduling problem, the vehicle scheduling problem (VSP) plays a significant role in public transportation systems. VSP is difficult to solve, since it is classified as a high-dimensional combination optimization problem, which is well known

Fuzzy Logic: A Content Analysis For Thesis And Article Studies Between 2000-2020

open access: yesActa Infologica, 2020
Today, quantitative data are being used to guide decision making processes as well as in performance determination studies. Using quantitative data prevents situations that can be expressed verbally from being expressed mathematically. Fuzzy logic offers
