This paper proposes a couple of criteria for evaluating the quality and relevance of a fuzzy partition. These criteria are established from a fuzzy classification system and its recursive De Morgan triplet. We propose a comparison process between the classes of a fuzzy partition, based on a translation invariant similarity relation. Therefore a classification process is carried out with the equivalence relations determined by the similarity relation. Such a relation is built on the commutative group structure formed by the elements of the fuzzy classification system. Our approach is illustrated through an example on image analysis by the fuzzy c-means algorithm.
El objetivo de este artículo, es presentar, de manera introductoria, aspectos existentes que permiten relacionar la lógica difusa con la toma de decisiones. Se inicia con una breve explicación de los elementos básicos, en un proceso de toma de decisiones, enfatizando en el ambiente de incertidumbre y en los aspectos subjetivos presentes en el mismo. Posteriormente, se realiza un acercamiento a la lógica difusa a través de algunos ejemplos, herramientas, conceptos generales y relaciones existentes con la incertidumbre y con la subjetividad, en general. Finalmente, se presenta un ejemplo y un listado de obras y trabajos realizados en torno a la toma de decisiones desde esta nueva lógica.
