Aggregation operators are currently embedded in several computer systems. They are basically used for modeling decisions as well as for summarizing information. In order to use the operators in real world applications, a large number of aggregation operators have been defined. Recent results in this research line include hierarchical models, that permit the aggregation of partial results. Also, as it is typically the case that operators require parameters, methods have been developed to help the users on the determination of the parameters.
