基于多层多级天际线选择方法的威胁评估

Threat assessment based on multilayer and multistage skyline selection method

传统的威胁评估均采用加权求和方法,最终得到的单一威胁度序列缺少各目标特征,且权值设定过程复杂。在天际线选择理论的基础上,提出了多级天际线选择方法,结合多层次威胁评估建模思想,建立了基于多层多级天际线选择方法的威胁评估模型,有效消除了权值设定过程中个人喜好等因素的干扰,并将每个目标在各评价维度上的属性特征呈现出来。仿真实验结果表明,获得的威胁评估结果全面直观,为指挥员依据不同情况进行后续决策提供了重要依据。

Traditional threat assessment uses weighted summation method.However,the final threat sequence lacks the characteristics of each target,and the weight setting process is complicated.Based on the theory of skyline selection,a multistage skyline selection method is proposed.Combined with the multi-level threat assessment modeling,a threat assessment model based on the multilayer and multistage skyline selection method is established,which effectively eliminates the interference of personal preferences and other factors in the process of weight setting.The attributes of each target on each evaluation dimension are presented.The simulation results show that the obtained threat assessment results are comprehensive and intuitive,providing an important basis for commanders to make follow-up decisions in different situations.
