Hierarchization process by possibilistic fuzzy clustering of fuzzy rules. In RECPAD. Vila Real. ISBN 978-972-669-990-3.978-972-669-990-3http://hdl.handle.net/10198/4832This paper presents a possibilistic fuzzy clustering algorithm that is applied to a multidimensional fuzzy set or fuzzy rules. This method can be used to decompose the fuzzy system into an hierarchical structure. The methodology presented leads to a fuzzy partition of the fuzzy rules, one for each cluster, which corresponds to a new set of fuzzy sub-systems. This technique is tested to organize the fuzzy model into a new and more comprehensive structure.engFuzzy clusteringHierarchizationconference object
