摘要: In this chapter we discuss some of the principles underlying what are often called “interactive” methods MCDM (or “progressive articulation preferences” in MCDM). These which full preference structure decision maker is not structured and elicited a priori, but evaluated progressively locally response to simple choices made by maker. We differentiate responses expressed terms tradeoffs (directly, or indirectly between pairs outcomes), aspiration levels (i.e. desired performance for each criterion). final section, report briefly on simulation studies have been undertaken order assess convergence properties interactive methods.
