摘要
在决策方案优劣等级排序分析和多层序等价类划分的基础上 ,构造了等级排序置换群 ,并提出了群决策中序位相同的可能排序数的解析和递推估计式 .分析结果显示 。
Based on the analysis of preference rankings in decision alternatives and decomposition of the deferent order equivalence classes, a ranking permutation group has been established. The analytic and recursive formulae for the evaluation of the possible ranking number with some order agreements in group decision making have been provided. It is shown that to maintain homogeneity in alternatives and negotiate conflicts in group are important ways to aggregate the preference rankings of individuals into a valid group consensus ranking.
