“…The 2-additive case in particular (see Miranda, Grabisch, and Gil, [46]; Mayag, Grabisch, and Labreuche, [43,44]) is a good trade-off between the range of the model and its complexity (only n(n+1)/2 real coefficients are required to define a 2-additive capacity). The Choquet integral with respect to a 2-additive capacity is an interesting and effective modelling tool, see for instance Marques Pereira and Bortot [41,42], Berrah and Clivillé [3], Clivillé, Berrah, and Maurice [9], Berrah, Maurice, and Montmain [4]. In this paper we propose an aggregation model based on Choquet integration with respect to a 2-additive capacity.…”
