针对现有威胁评估方法很难体现防空反导作战所具有的来袭目标种类复杂、信息不确定等特点的问题,提出了一种基于区间数变权法的目标威胁评估方法。首先,构造了混合型变权函数以用于区间数型目标威胁评估指标权重的调整;然后,通过求解非线性规划求取了区间数型目标威胁值,并根据区间数比较的可能度方法给出了威胁排序规则;最后,进行了实例计算,结果表明该方法是合理可行的。
In view of the fact that the existing threat assessment methods are difficult to reflect the characteristics such as the complicated target types and the uncertain information of incoming targets in air defense and missile defense operations, a target threat assessment method based on interval number variable weight method is proposed. First of all, a hybrid variable weight function is constructed to adjust the index weight of the interval type threat assessment index. Then, by solving the non-linear programming, the interval threatening target number is obtained and the probability of interval number comparison is given Finally, a case calculation is made and the result shows that the method is reasonable and feasible.
