Research Abstract	In this study a solution method was proposed for a class of multi-objective optimization problems which had not been addressed by the existing methods. When solving a multi-objective optimization problem where the decision maker finds the best alternative among a number of alternatives based on multiple evaluation criteria, the preference of the evaluator is necessary which indicates which criterion is more important than the others. The existing methods assume that the decision maker and the evaluator are the same person, while in reality there are problems where they are distinct persons. For this kind of problems, a method was developed which can properly estimate the evaluator's preference and find the solution based on it, and its validity was confirmed by application examples.
