The Theory of Fuzzy Logic and its application to Real Estate Valuation [PDF]

open access: yes, 1998
Fuzzy logic is based on the central idea that in fuzzy sets each element in the set can assume a value from 0 to 1, not just 0 or 1, as in classic set theory. Thus, qualitative characteristics and numerically scaled measures can exhibit gradations in the

Measurable prediction for the single patient and the results of large double blind controlled randomized trials. [PDF]

open access: yesPLoS ONE, 2008
BACKGROUND: It has been shown that the clinical state of one patient can be represented by known measured variables of interest, each of which then form the element of a fuzzy set as point in the unit hypercube. We hypothesized that precise comparison of

Fuzzy solutions of some variants of the fractional order Korteweg-de-Vries equations via an analytical method

open access: yesAlexandria Engineering Journal, 2023
Under uncertainty, the analytical behaviour of fractional partial differential equations is frequently puzzling and challenging to predict. Therefore, in order to address these problems, it is essential to create a proper, extensive, and highly effective

On the Minkowski-H\"{o}lder type inequalities for generalized Sugeno integrals with an application [PDF]

open access: yes, 2015
In this paper, we use a new method to obtain the necessary and sufficient condition guaranteeing the validity of the Minkowski-H\"{o}lder type inequality for the generalized upper Sugeno integral in the case of functions belonging to a wider class than ...

A New Divergence Measure of Pythagorean Fuzzy Sets Based on Belief Function and Its Application in Medical Diagnosis

open access: yesMathematics, 2020
As the extension of the fuzzy sets (FSs) theory, the intuitionistic fuzzy sets (IFSs) play an important role in handling the uncertainty under the uncertain environments.

Synthetic Emotions for Empathic Building

open access: yesMathematics, 2021
Empathic buildings are intelligent ones that aim to measure and execute the best user experience. A smoother and intuitive environment leads to a better mood. The system gathers data from sensors that measure things like air quality, occupancy, noise and

M-CFIS-R: Mamdani Complex Fuzzy Inference System with Rule Reduction Using Complex Fuzzy Measures in Granular Computing

open access: yesMathematics, 2020
Complex fuzzy theory has strong practical background in many important applications, especially in decision-making support systems. Recently, the Mamdani Complex Fuzzy Inference System (M-CFIS) has been introduced as an effective tool for handling events

Sharp and fuzzy observables on effect algebras

open access: yes, 2007
Observables on effect algebras and their fuzzy versions obtained by means of confidence measures (Markov kernels) are studied. It is shown that, on effect algebras with the (E)-property, given an observable and a confidence measure, there exists a fuzzy ...

Multi-attribute group decision making based on Choquet integral under interval-valued intuitionistic fuzzy environment

open access: yesInternational Journal of Computational Intelligence Systems, 2016
In this paper, we propose new methods to represent interdependence among alternative attributes and experts’ opinions by constructing Choquet integral using interval-valued intuitionistic fuzzy numbers.
