基于改进TOPSIS法的混合多类型属性威胁评估

摘要

针对舰艇编队反导作战威胁评估过程中存在的目标属性信息类型多样化问题，首先构建威胁评估指标体系，然后设计一种能够直接处理实数型、区间数型及模糊三参数区间数型属性信息的威胁评估方法。该方法能够在保留目标属性信息格式的基础上直接集结目标属性信息，对目标的威胁程度进行评估。仿真实例证明，设计的方法能够直接对混合多类型属性条件下的目标威胁程度进行评估，且计算量较小。%Aiming at hybrid multi-type attribute of targets in ship formation anti-missile threat assessment process,builds the index system firstly,then designs the improved TOPSIS method which can solve real-number type index,interval type index and fuzzy interval numbers of three parameters directly,and this method can evaluate the multiple attributes and threat degree of target without losing attribute information. A numerical example is given to illustrate the method, and the result demonstrates this method can obtain threat degree of the hybrid multi-type attribute targets fast and reliably.
