用无差异有效点集求较多有效解

Finding Major Efficient Solutions Through Indifferent Efficient Point Set

以实际中常见的有限约束集的多目标决策问题为对象，提出无差异有效解的概念．讨论了无差异有效解与较多有效解的关系．给出了一个求解多目标决策问题较多有效解的新方法．

Being a king of solution of multicriteria decision problem,the major efficient solution is based on the preference principle of“better objectives are in the majority”.This paper offers a concept of indifferent efficient solution with respect to multicriteria decision problems in which the constraint sets are finite and common in actual situations.The relationship between major efficient solutions and indifferent efficient solutions is discussed,and an new method for finding the major efficient solutions is given.
