摘要
基于格序偏好结构的研究,证明了格序决策方案集中的同层不可比关系是等价关系,提出了将具有格序结构的决策方案集按层分类,该方案集在等价类间的优劣关系下构成了一个链结构,即偏好结构链化,使格序结构向全序或非对称弱序结构转化.
Based on lattice-ordered preference structure,in this paper we show that the set of the alternatives,which are incomparable with each other under lattice order relation,is an equivalent class.And we proposes a method to classify the lattice order decision-making alternatives based on this equivalence.Meanwhile,it is proved that all incomparability layers under the advantage relation form chain structure.
