本文提出了一种基于定性推理技术来表示和综合一组评价者给出的信息的新方法。建立了一个数学公式，有助于在多属性和群体决策的背景下进行决策分析。该方法适用于选择和排序问题，可以在不同的精度水平上工作。为了表示非平凡的领域知识，要排序的模式或备选方案由一组特征来表征，这些特征由组中的每个成员通过与序数相对应的语言标签来评估。不同的精度水平被认为是绘制评估者的推理过程所需的区别。用于对备选方案进行排序的方法是基于比较与最佳参考点的距离。提出并证明了该方法的一致性定理。本文提出了三个实际应用，概述了所提出的方法已经实施并取得有趣结果的管理领域。
This paper presents a new approach based upon qualitative reasoning techniques for representing and synthesising the information given by a group of evaluators. A mathematical formulation is developed that contributes to decision-making analysis in the context of multi-attribute and group decision-making. This method, is applied in choice and ranking problems and can work at different precision levels. To represent non-trivial domain knowledge, the patterns or alternatives to be ranked are characterised by a set of features, which are evaluated by each member of the group through linguistic labels corresponding to ordinal values. Different levels of precision are considered to draw the distinctions required by evaluators’ reasoning processes. The method used for ranking alternatives is based on comparing distances against an optimal reference point. A theorem on the consistency of the proposed method is presented and proved. Three real-life applications are presented to outline areas of management where the proposed method has been implemented and achieved interesting results.
