En este artículo se presenta una forma de generalización para el Delphi difuso, el cual comprende una clase amplia y contentiva de las versiones intuicionista y pitagoreana.

This article presents a framework of generalization for the Delphi fuzzy, which comprises a broad class that containing both the intuitionist and Pythagorean forms. An application example is also presented and some variants for prognostic improvement are discussed.]]></p></abstract>
