Efficient parametric adjustment of fuzzy inference system using unconstrained optimization
(2007-12-01)
This paper presents a new methodology for the adjustment of fuzzy inference systems, which uses technique based on error back-propagation method. The free parameters of the fuzzy inference system, such as its intrinsic ...
Tuning of fuzzy inference systems through unconstrained optimization techniques
(2003-12-01)
This paper presents a new methodology for the adjustment of fuzzy inference systems. A novel approach, which uses unconstrained optimization techniques, is developed in order to adjust the free parameters of the fuzzy ...
Development of a water quality index using a fuzzy logic: A case study for the sorocaba river
(2010-11-25)
Due to growing urbanization and industrialization, the environment is suffering from pollution of rivers, degradation of soils and deteriorated air quality. Quality indices appear to be useful to evaluate the conditions ...
A Proposal for Reliability Evaluation of Components on Electric Power Distribution System Integrating Probabilistic Models and Fuzzy Inference Systems
(Ieee, 2012-01-01)
The system reliability depends on the reliability of its components itself. Therefore, it is necessary a methodology capable of inferring the state of functionality of these components to establish reliable indices of ...
Design of a simplified neuro-fuzzy system based on CMAC Architectures
(Int Inst Informatics & Systemics, 2001-01-01)
This work presents the design of a fuzzy controller with simplified architecture that use an artificial neural network working as the aggregation operator for several active fuzzy rules. The simplified architecture of the ...

Fuzzy environmental quality index
(2010-11-25)
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 ...
Risk prediction for weed infestation using classification rules
(2009-12-01)
This paper proposes a fuzzy classification system for the risk of infestation by weeds in agricultural zones considering the variability of weeds. The inputs of the system are features of the infestation extracted from ...
An approach via fuzzy systems for dynamics and control of the soybean aphid
(Atlantis Press, 2015-01-01)
This paper uses a methodology based in fuzzy sets theory in order to describe the interaction between the prey, Aphis glycines (Hemiptera: Aphididae) the soybean aphid, and its predator, Orius insidiosus (Hemiptera: ...
