群体多目标决策联合有效解类的几个最优性充分条件

Some Optimality Sufficient Conditions for Joint Efficient Solution of Group Multiobjective Decision Making Problem

对于群体多目标决策问题，文献［１］利用供选方案的有效数引进一类基本的联合有效解概念，并且给出了此类解要满足的最优性必要条件．本文在一定凸性要求下，建立了群体多目标决策问题联合有效解类的若干最优性充分条件．

For group multiobjective decision making problems, a class of joint efficient solutions is introduced by means of efficient numbers of alternatives and the optimality necessary conditions are established in the paper [1]. In this paper, some optimality sufficient conditions for joint efficient solution of group multiobjective decision making problems are obtained under the assumption of some convexity.
