On aggregation operations of linguistic labels. (English) Zbl 0794.68154

Summary: This article is devoted to defining some aggregation operations between linguistic labels. First, from some remarks about the meaning of label addition, a formal and general definition of a label space is introduced. After, addition, difference, and product by a positive real number are formally defined on that space. The more important properties of these operations are studied, paying special attention to the convex combination of labels. The article concludes with some numerical examples.
