En este trabajo se adapta la medida de Información dada por Onicescu en 1966, denominada Energía Informacional, a situaciones en las cuales existe una función de utilidad definida sobre los resultados del experimento; a esa medida de Información la denominaremos Energía Informacional Útil.
The information-theoretical entropy is an effective measure of uncertainty connected with an information source. Its transfer from the classical probabilistic information theory models to the fuzzy set theoretical environment is desirable and significant attempts were realized in the existing literature. Nevertheless, there are some open topics for analysis in the suggested models of fuzzy entropy - the main of them regard the formal aspects of the fundamental concepts. Namely their rather additive...
