Vague物元及熵权的空袭目标威胁评估

Threat Evaluation of Air Attack Targets Based on Vague Matter-Element and Entropy Weight

为了应对防空反导作战需求,提出了一种基于Vague物元及熵权的空袭目标威胁评估方法。建立了空袭目标威胁评估复合Vague物元的概念,提出了一种新的将复合Vague物元转化为适合度物元的排序函数,使复合Vague物元便于量化处理,并运用熵权法客观地计算出了各空袭目标属性的权重,根据空袭目标威胁评估物元与正负理想物元的相对贴近度最终得到了目标威胁程度的排序。实例分析验证了该方法的实用性和有效性。

Aiming at the need of air defence and antimissile battles, a threat evaluation method based on Vague matter-element and entropy weight is put forward. It is established that the complex vague matter-element is evaluated by air attack target threat. Then a new taxis function that can turn complex Vague matter-element to fitness matter-element is founded, which makes the quantization process convenient. And the entropy weight method is used to calculate the weight of all air attack target attributes. Finally, the taxis of target threat extent is obtained according to relative close to the degree between the complex Vague matter-element of air attack target threat evaluation and the plus minus ideal matter-element. The evaluation method is proved to be practicable and effective by an example.
