摘要 OWA算子是一种重要的多属性综合决策方法,广泛应用于各种管理与决策领域,如何科学地给出OWA算子的权重是这一领域重要的问题之一.基于组合数的对称性质,提出了一种具有截断均值评价法的特点,又考虑到评价者乐观程度的OWA赋权模型,由于该模型可以表示成一个二次规划,所以计算效率比较高.给出了这种赋权模型的2条性质,说明了这个模型的解与乐观程度之间的关系.最后利用文中提出的模型对若干个出版物进行综合评价,说明了这种赋权模型的使用方法. The OWA operator is an important averaging method in multiple attribute decision making.How to assign reasonable weights of OWA operators is an important issue in this field.Based on the density function of binomial distribution,a new method similar to trimmed mean was proposed.The orness level was a parameter in this method.Two propositions are proven,and a numerical example was given to analyze and illustrate this method.
