| 摘 要： | 针对展望空间的偏好结构按照一定的偏好关系不具有连通性的情况，关于决策方案的比较提出了一种格序决策方法。证明了展望空间按照极大多数优于原则是一个偏序集．具有格序特征；得出了格序展望空间的上赋值和距离函数，并根据赋值和距离函数刻画出决策后果之间的偏好距离，即优劣差异程度；最后，举例加以说明。

| Abstract: | A lattice order decision making method about alternative's ranking is proposed, when the preference structure of prospect spaces without connected axiom according to some preference relation.It is proved that the prospect spaces are a poset,and with lattice order characteristic;the value function and distance function have arrived,the preference distance of decision outcomes have been worked out by the value function and distance function.Feasibility and effectiveness of the(approach) proposed in this paper are illustrated with a numerical example. |
