Linguistic-Valued Intuitionistic Fuzzy 2-Tuple Representation Model
Li Zou · 2014
A kind of linguistic-valued intuitionistic fuzzy 2-tuple representation model is proposed based on the linguistic truth-valued intuitionistic fuzzy lattice. The operations and the properties of linguistic-valued intuitionistic fuzzy pair are discussed. Based on the proposed model, a kind of linguistic-valued intuitionistic fuzzy aggregation approach is defined. Arithmetic mean aggregation operator and weighted average aggregation operator are given respectively. Using the aggregation operations of the linguisticvalued intuitionistic fuzzy pairs,the information loss is reduced in the process of the aggregation for linguistic-valued intuitionisttic fuzzy pair. A recognition process of disease diagnosis is given to illustrate that the proposed approach is more effective for pattern recognition under a fuzzy environment with both positive evidence and negative evidence.
