In particular, we suggest that the concept of an aggregation rule should be defined from a computational point of view, focusing on the computational properties of such an aggregation, i.e., on the manner in which the aggregation values are computed. The new algorithmic definition of aggregation we propose provides an operational approach to aggregation, one that is based upon lists of variable length and that produces a solution even when portions of data are inserted or deleted. Among other advantages, this approach allows the construction of different classifications of aggregation rules according to the programming paradigms used for their computation or according to their computational complexity.engjournal articlehttps//doi.org/10.1016/j.ins.2017.10.012http://www.sciencedirect.com/science/article/pii/S0020025517310058open access519.21Aggregation operatorAggregation functionAggregation ruleProbabilidades (Matemáticas)
