针对预警机多目标优先级的排序问题,提出一种改进的层次分析(IAHP)的排序方法.通过量化各影响因子,建立关于影响因子属性值及其权重的目标优先级函数.基于区间数判断矩阵思想,对权重进行上下限及可能值的分析,提出一种新的权重求解模型,并通过引入遗传算法,求得了各权重值.改进方法消除了1~9标度法求解时的主观性和随意性.最后通过仿真实例,求出目标优先等级,并结合真实态势的要求,验证了文中方法的有效性与可行性.

In view of ordering problem of multiple target priority in the early warning aircraft combat scenes, an improved analytic hierarchy process (IAHP) algorithm was proposed. Firstly, by quantifying influence factors, the target priority function about the influence factor and weight values of attributes was established. Based on the concept of interval comparison matrix, the weight of upper and lower limit and possible value were analyzed, then a new weight solution model was produced, by introducing genetic algorithm, the weight values were obtained. The improved algorithm eliminated the subjectivity and arbitrariness of 1~9 scaling method. Finally, the simulation results showed the priority objective of targets, compared with real battlefield environment; effectiveness and feasibility of the proposed method were verified.
