构建了威胁评估的指标体系,基于模糊隶属函数对各指标进行了模糊化处理.依据作战实际情况,分别建立了无属性权重信息三种不同类型的威胁评估模型.通过不确定决策的方法获取目标威胁评估值和排序结果.所建立的三种不同类型的威胁评估模型更为符合作战的实际过程,可以为防空作战指挥提供科学的理论依据.算例表明了方法的有效性. The index system of threat assessment is constructed and each index is fuzzified based on fuzzy membership function.According to the actual combat situation, three different types of threat assessment models with no attribute weight information are established respectively, and the target is obtained by the method of uncertainty decision Threat assessment and sequencing results.The three different types of threat assessment models established are more in line with the actual operational process and provide a scientific theoretical basis for the air-defense combat command.The examples show the effectiveness of the method.
