In this sense, this research is a consequence of a previous paper from the authors,already published in Fuzzy Sets and Systems (2007), where classical associative aggregation functions where linked to linear structures of data, meanwhile data quite often show a complex (non linear) structure moving within a spatial framework.engbook partrestricted access519.8Aggregation functionsAggregation rules.Investigación operativa (Matemáticas)1207 Investigación Operativa
