摘　　要：为解决排序方案多属性特征、决策者对事物认识的局限性以及决策群体中各个体间的矛盾性导致的决策方案排序困难的问题,引入模糊相似度概念,以测度决策专家的偏好差异,用有序加权平均算子集结群体意见,通过与虚拟正、负理想方案比较,实现决策方案排序,并介绍了决策实施步骤.It is difficult to rank alternatives in group decision-making because of multi-attributes,limitations to policy-makers in their understanding of matter under discussion,and contradiction in the decision-makers.To solve this problem,fuzzy similarity was introduced to measure the preference differences from the decision-makers,and their opinions were summed up using OWA（ordered weighted averaging） operator.Alternative Ranking was realized by comparing the alternatives with virtual positive and negative ideal solutions.The procedure for the decision-making was presented.
