Fuzzy sets play a pivotal role in computing with words being casted in the setting of granular computing (cf. ,zedeh2006b). "The essence of granular computing is to carry out computing that exploits information granules" ,zedeh2006b. Information granules are regarded as collections of elements that can be perceived and treated together because of their similarity, functional properties, or spatial or temporal adjacency , , , . In this sense, fuzzy logic becomes instrumental as an effective vehicle to manipulate information granules.
