Interactive Multiobjective Nonlinear Programming with Fuzzy Parameters

In this chapter, attention is focused on multiobjective nonlinear programming problems with fuzzy parameters, which reflect the experts’ ambiguous or fuzzy understanding of the nature of the parameters in the problem-formulation process. By extending the usual Pareto optimality concepts, interactive decisionmaking methods, both without and with the fuzzy goals of the decision maker (DM), for deriving a satisficing solution efficiently from an extended Pareto optimal solution set are presented.
