摘要
为了解决评价信息为语言信息的多属性群决策问题,结合VIKOR方法,提出一种基于二元语义信息处理的多属性群决策方法.该方法使用二元语义信息集结算子获得决策群组的决策信息,通过最大化群效用和最小化个体遗憾来获得决策者满意的折衷方案.该方法计算简单,便于理解,可有效避免信息的丢失和扭曲,并可克服理想解方法不能反映出各方案与正负理想解的接近程度的不足.最后,算例计算结果表明了该方法的有效性.
To deal with multiple attributes group decision making problems with linguistic assessment information, a two-tuple linguistic multiple attributes group decision making method based on VIKOR method is proposed. This method aggregates single users＇ decision information to get group＇s decision information, and obtain the best compromise solution by maximizing group utility for the majority and minimizing individual regret for the opponent. This method is easy to implement and interpret, and can avoid the loss and distortion of assessment information effectively. Moreover, the proposed method can overcome the shortcomings of the ideal solution method, which cannot reflect the relative importance of distances from the alternative to the positive ideal solution and negative ideal solution. Finally, the result of the numerical example shows the effectiveness of the proposed method.
