针对不协调广义多尺度序决策信息系统中的最优尺度组合和IF-THEN知识获取问题，首先，提出了集值优势矩阵的概念，给出了其判断序决策信息系统是否协调的条件。然后，在不协调的广义多尺度序决策信息系统中，引入基于优势关系的广义决策概念，同时通过定义区间值优势关系的方法，构造了新的协调广义多尺度序决策信息系统，并设计了通过集值优势矩阵求最优尺度组合的算法，挖掘了隐藏在不协调广义多尺度序决策信息系统中的决策规则。最后，通过实验验证了所提广义决策最优尺度组合的有效性。
Abstract：Aiming at the problem of optimal scale combination and IF-THEN knowledge acquisition in inconsistent generalized multi-scale ordered decision information systems, the concept of set-valued dominance matrix was firstly proposed, and the conditions for judging whether an ordered decision information system was consistent were given. Then, in the inconsistent generalized multi-scale ordered decision information system, the concept of generalized decision based on dominance relation was introduced. At the same time, a new consistent generalized multi-scale ordered decision information system was constructed by defining the interval-valued dominance relation, and an algorithm for finding the optimal scale combination through the set-valued dominance matrix was designed. The decision rules hidden in the inconsistent generalized multi-scale ordered decision information system were mined. Finally, the effectiveness of the proposed optimal scale combination of generalized decision was verified by experiments.
