为解决不完备信息系统条件下的舰艇编队综合防空来袭目标威胁度量问题,提出了一种基于不完备信息系统的舰艇编队威胁度量规则的提取方法。通过研究不完备信息系统中条件属性缺失下的信息补全和决策属性缺失下的策略生成,得出专家决策信息最为相似时的折扣系数。在满足防空决策要求的前提下,设定???的取值求取不完备信息系统的约简规则。该方法能在条件属性和决策属性都存在部分缺失的情况下提供满足支持度的目标威胁度量,给水面舰艇编队防空提供决策依据。
In order to solve the problem of target threat measurement in the formation of an integrated air defense fleet under the condition of incomplete information system, a method to extract the threat measurement rules of a ship formation based on the incomplete information system is proposed. By researching the information complementation under the missing conditional attributes and the strategy generation under the missing decision attributes in the incomplete information system, the discount coefficient when the expert decision information is the most similar is obtained. Under the premise of meeting the requirements of air defense decision, set the value of ??? to get the reduction rule of incomplete information system. This method can provide the target threat measure that satisfies the support degree when there are some missing condition attributes and decision attributes, and provide decision-making basis for air defense of surface warship formation.
