摘要
群体多目标决策是群体决策和多目标决策的一个交叉研究领域．借助供选方案的有效数，文［１］引进了群体多目标决策问题的联合有效解类概念，并且建立了这些解类的Ｋ－Ｔ最优性条件．本文研究这类解的几何特性，得到若干基本的必要条件和充分条件．
Group multiple criteria decision making (GMCDM) is an overlapping field of group decision making and multiple criteria decision making. With the help of efficient numbers of alternatives, concepts of a class of joint efficient solutions and K-T optimality conditions of these solutions are both presented for the GMCDM problem in paper [1]. In this paper, the geometric characterizations of the joint efficient solutions are studied, and some basic necessary conditions and sufficient conditions are obtained.
