A Hierarchical Ordinal Model for Managing Unbalanced Linguistic Term Sets Based on the Linguistic 2-tuple Model 0

The use of the Fuzzy Linguistic Approach implies processes of Computing with Words. These processes can be carry out without loss of information using uniformly distributed linguistic term sets represented by a model based on linguistic 2-tuples. However there exist problems when linguistic values cannot be adapted to a symmetrically and uniformly distributed ordinal linguistic scale. In this contribution we present a method that allows us to manage unbalanced linguistic term sets, such that, the processes of Computing with Words can be carried out without loss of information.
