针对具有语言评价信息的多属性群决策问题,提出基于广义优序法的语言型多属性群决策方法.该方法通过对传统优序法进行有效拓展,采用近年来最新发展的二元语义概念,将语言评价信息转化为二元语义形式的广义优序数,并在此基础上利用方案广义优序数的偏差最大化思想求解得到属性权重,最终确定最优方案.该方法对语言信息的处理较为精确,有效地避免了信息的丢失和扭曲.最后,通过对风险投资案例的分析结果表明了所提出方法的简洁性和有效性.
To solve the problem of multi-attribute group decision making with linguistic assessment information, a linguistic multiple attribute group decision-making method based on generalized order-priority method is proposed. This method extends the traditional pre-order method and adopts the latest development of binary semantic concepts in recent years. The linguistic assessment information is transformed into generalized ordinal numbers in the form of binary semantics, and based on this, the attribute weights are obtained by using the maximization deviation of the generalized ordinal numbers of programs, and the optimal solution is finally determined.The method is more accurate in handling linguistic information , Effectively avoiding the loss and distortion of information.Finally, the analysis of the venture capital case shows the simplicity and effectiveness of the proposed method.
