摘    要:鉴于已有优势决策信息系统规则获取方法存在不足,如得到规则较少、规则正确率不高等,定义优势决策辨识集和辨识矩阵,给出优势决策信息系统的属性约简方法;引入基于优势关系的粗糙集方法将对象进行优劣排序,并结合决策属性剔除不合理对象,将不协调优势决策信息系统转化为协调优势决策信息系统;提出协调优势决策信息系统的规则获取方法,该方法符合自然推理过程,直观性强,在充分挖掘系统蕴含信息的基础上,保证了规则的正确性;将该规则获取方法应用于雷达对抗目标威胁评估简单可行,并为解决属性含有"偏好信息"的决策问题提供了新的思路。

关 键 词:系统评估与可行性分析  粗糙集  属性约简  优势关系  规则获取  威胁评估

Abstract:Inview of the disadvantages of the existing rule acquisition method of dominance decision-making information system, such as small number rule acquirement or low rule accuracy, the decision discernibility set and discernibility matrix are defined, and an attribute reduction method of dominance decision-making information system is prsented. The rough set method based on dominance relation is applied to rank the objects, and then eliminate the unreasonable object compared with the decision attribute, and then the inconsistent dominance decision-making information system is transformed to the consistent one. The rule acquirement method of the consistent dominance decision-making information system is proposed, which conforms to the natural reasoning process and has strongly intuitionistic characteristic. The proposed method fully digs the information from the system and ensures the validity of the rules. This rule acquisition method is applied to radar target threat assessment, which is simple and feasible, and provides a new train of thought to solve the decision problem of which attribute contains “preference information”.
Keywords:system assessment and feasibility analysis  rough set  attribute reduction  dominance relation  rule acquisition  threat assessment
