Sensory Evaluation Model with Unbalanced Linguistic Information

摘要

The evaluation processes are used for quality in-spection, marketing and other fields in industrial companies. This contribution focuses in sensory evaluation where the evaluated items are assessed according to the knowledge acquired via human senses by a panel of experts. In these evalua-tion processes the information provided by the ex-perts implies uncertainty, vagueness and impreci-sion. The use of the Fuzzy Linguistic Approach [1] has provided successful results modeling such a type of information. Usually evaluation processes based on linguistic approaches use symmetrical and uniformly distributed linguistic term sets in order to express their preferences about the evaluated ob-jects. However, there exist problems whose assess-ments need that one side of the scale overweight the other one, it means an unbalanced linguistic scale.In this contribution we present a sensory evaluation model that manages frameworks with unbalanced linguistic information.
