Mind map of chapter 18: transition from Part II's grammar to comparison criteria C_1…C_n, distinction between preferential question (MCDA) and descriptive (multidimensional data analysis), four-step method (criteria, matrix E(L,C_i), comparison without weights with Pareto, weighting + sensitivity) and precautions of use.
