The MCDA approaches have been developed to deal with problems such as ranking, sorting or quantification. The purpose of this paper is to describe the operational aspects in MCDA deployment through a case study submitted by the SME Fournier Company. This paper concerns analytical overall performance models to allow the DMs to select potential actions to launch regarding given decision criteria. The principles of the main MCDA approaches are presented. Then representative MCDA methods, ELECTRE III and MACBETH, are successively deployed to a tactical decision problem of business turn-over increase. From the building of their respective preference modelling, decision aid is provided in the form of preference relation or performance function. A formal framework supplying information to the industrial DMs in order to legitimate the action selection is described. In addition the DMs feedback highlights the required expertise for the preference modelling.
