This paper proposes the discrete-time fuzzy interval optimal control problem via single-level constrained fuzzy arithmetic. Fuzzy interval functions are established and allow us to evaluate the dynamics of the fuzzy interval ...

This paper presents the construction of a fuzzy environmental quality index for decision support in municipal environmental management. Five groups of indicators were selected in order to obtain an equation that best ...

This research aims to use the fuzzy relations to diagnose patients infected with the virus transmitted by the mosquito Aedes aegypti, which can be diagnosed with dengue, chikungunya or zika. For this we use fuzzy relational ...

The idea of considering imprecision in probabilities is old, beginning with the Booles George work, who in 1854 wanted to reconcile the classical logic, which allows the modeling of complete ignorance, with probabilities. ...

This study provides a new characterization of the switching points for generalized Hukuhara differentiable fuzzy-valued functions. New results on generalized Hukuhara differential and integral calculus for fuzzy-valued ...

Desde cedo entramos em contato com as implicações lógicas. O binômio verdadeiro-falso está sempre presente em nossas vidas e nós nos acostumamos a aceitar que as coisas ou são verdadeiras ou são falsas. Divertimo-nos quando ...
