Rules extraction, rules insertion and a method of alternative training and zeroing, based on zeroing of small connections in a fuzzy neural network, have been investigated in respect of adaptation and forgetting phenomena. The experiments show that updated (zeroed) fuzzy neural networks are more robust to forgetting, faster and better at adaptation and provide a good generalisation. The method ...

The interconnectedness of knowledge implies the need for a transdisciplinary attitude between humans and computers. This paper proposes method requirements BOMs engineering their chaining toward CAD models. Agents multi-agent systems are considered modelled as concepts. cooperative agent-based platform F-EGEON (Fuzzy Engineering desiGn sEmantics elabOration applicatioN) is developed engineering...

The distribution of structural planes is complex and irregular. How to quickly effectively obtain the occurrence characteristics improve efficiency data processing a key technical issue in plane analysis. paper combined fuzzy equivalent clustering algorithm, rose diagram drawing method, C++ language, developed system for pole rock mass planes, verified practicability through an engineering case...

Fuzzy Logic Controllers are a specific model of Fuzzy Rule Based Systems suitable for engineering applications for which classic control strategies do not achieve good results or for when it is too difficult to obtain a mathematical model. Recently, the International Electrotechnical Commission has published a standard for fuzzy control programming in part 7 of the IEC 61131 norm in order to of...

The integration of fuzzy systems and neural networks has recently become a popular approach in engineering fields for modelling and control of uncertain systems.

Mathematical equations for the multi-criteria task of the optimisation of chemical engineering systems, for example for the optimisation of working regimes for industrial installations for benzene production, have been formulated and developed, and based on fuzzy mathematical methods, algorithms for their solution have been developed. Since the chemical engineering system, which is being resear...

The subject of this thesis forms part of a research program dealing with fractured rock masses being undertaken by the "Centre de Géologie de l'Ingénieur (CGI)" from the "Ecole Nationale Supérieure des Mines de Paris (ENSMP)" and the "Ecole Nationale des Ponts et Chaussées (ENPC)". In fractured rock masses, it is very difficult to undertake engineering works without analysing, beforehand, the f...

investigation of reliability characteristics under fuzzy environments is proposed in this paper. fuzzy weibull distribution and lifetimes of components are using it described. formulas of a fuzzy reliability function, fuzzy hazard function and their α-cut set are presented. furthermore, the fuzzy functions of series systems and parallel systems are discussed, respectively. finally, some numeric...
