Elicitation, evaluation and recommendation in multi-criteria decision making process

Traditionnally, multi-criteria decision making (MCDM) literature has devoted its effort to the evaluation and recommandation stage of decision analysis. A MCDM problem in this context is therefore completly determined by a table where the entry at a position of this table corresponds to the value of a criterion for the corresponding action and the main purpose for the analyst is to design a procedure that derive an order or pre-order over the actions set from that data table. This framework does have some drawbacks in practice such as the necessity for actions to be evaluated through the same criteria and one objective to realize. In this communication we go further ahead to consider also elecitation and measurement stage and derive a framework that allows also inhomogeneity of attributes that will characterize actions with regard to pursued multi-objectives. A case study in infrastructures projects portfolio selection under fund constraints to enhance suistainable development is considered as an illustrative application of the developped approach.
