Interactive Methods

Abstract

The class of interactive methods is the most developed of the four classes of methods presented here. The interest devoted to this class can be explained by the fact that assuming the decision maker has enough time and capabilities for co-operation, interactive methods can be presumed to produce the most satisfactory results. Many of the weak points of the methods in the other three classes are overcome. Namely, only part of the Pareto optimal points has to be generated and evaluated, and the decision maker can specify and correct her or his preferences and selections as the solution process continues and (s)he gets to know the problem and its potentialities better. This also means that the decision maker does not have to know any global preference structure. In addition, the decision maker can be assumed to have more confidence in the final solution since (s)he is involved throughout the solution process.
