摘　　要：从预警机指挥引导的多机协同空战原则分析出发,针对超视距协同空战决策过程中的不确定性和不完备性问题,提出了一种不完备信息系统中的基于双向启发式属性约简的战术粗决策建模方法。首先考虑粗糙集决策过程中条件属性发生缺失或不确定的情况,根据扩展不完备信息概念建立了不完备决策信息系统的最优完备选择;其次基于分辨矩阵的属性约简算法,以属性频度的大小作为启发信息进行决策信息系统约简的双向选择,得出决策信息系统的最佳约简集合;然后依据使决策最有可能发生的原则,给出决策信息系统的最优选择,以该最优选择为代表提取出决策规则;最后根据软、硬杀伤结合使用的CGF实体超视距协同空战作战想定,建立了CGF实体综合战术决策模型,并通过作战决策实例对该方法的正确性和有效性进行了验证。结果表明:该方法能在作战态势信息不完备的情况下正确给出CGF实体综合战术行为。Starting from the multi-aircrafts cooperative air combat under command and control of early warning aircraft task principle analysis,a tactics decision-making modeling based on bidirectional heuristic attributes reduction in incomplete information system is put forward,which aims at the uncertain and incomplete question in the decision making process for the beyond-visual-range cooperative air combat.Firstly,considered the decision-making attributes missing or uncertain in the rough set decision,the complete selection of the incomplete decision-making information system is established according to the concept for the extended incomplete information;Secondly,based on the attributes reduction with discernibility matrix,the most value of the attributes frequency as heuristic information is selected to make bidirectional selection for the decision-making information system attributes reduction,which is to get the most optimal reduction;And then,the optimal selection of the decision-making information system is presented according to the principle to make the decision have the maximum probability.The decision-making rules is extracted from the optimal selection;Lastly,according to the combat＇s tentative plan for CGF entity in the beyond-visual-range cooperative air combat,in which both soft and hard kill weapons are applied,a synthesized tactical decision-making model for CGF entity is established.A decision-making example has been presented to illustrate the decision-making course and verified its correctness and validity.The results show that the method can present the synthesized tactical actions for CGF entity accurately in the condition of incomplete combat＇s information.
