基于FMADM的制导雷达故障危害性决策分析

Decision Analysis on Failure Damages Guidance Radar Based on FMADM

在地空导弹武器系统仿真中,制导雷达的完好率直接影响对地空导弹武器整体作战效能的描述。某型照射制导雷达结构复杂,受不利因素的影响,容易导致发生各种故障,给人员与装备带来安全隐患的同时,会降低武器装备的整体作战能力。实践发现,不同的故障对装备造成的危害程度不同,并会产生许多不确定的因素。运用模糊多属性决策方法(FMADM)对照射制导雷达故障危害性进行决策分析,建立危害性判别的指标体系,选择梯形模糊数表示权重,采用逼近理想点(TOPSIS)方法,利用与理想解的相对贴近度对照射制导雷达不同故障危害性进行排序,为防空作战仿真中地空导弹武器系统建模提供细化的建模支持。同时,也可为降低或规避装备故障危害提供辅助决策及装备优化依据。

In ground-to-air missile weapon system simulation,perfectness ratio of guidance radar may effect the description to combat effectiveness of the whole system.The illuminator guidance radar is a complex weapon system,because of various adverse factors,which may result in many types of failures and bring the safety risks to the personnel and equipments.Based on the analysis of current failures’ recording information,it can be out that different failures may bring about various damages,engendering many uncertain factors.Analyzing the damages decision making to the radar by applying PMADM,setting up the index to judge the damage quality,picking up trapezoidal fuzzy judgment matrices as weight and applying the TOPSIS way,giving the different damages a taxis the according to the relative nearness degree of ideal solution,may support the detailed model of ground-to-air weapon system in air defense simulation,support decision making to reduce or avoid the failure damages,and optimize the equipment.
