基于灰理论的威胁评估方法

威胁评估既有利于合理分配战场资源以进行科学的攻防决策，又能更好的保存自己，有力的打击敌人，因此建立一个可信度较高的通用的威胁评估体系很有必要。影响威胁评估的因素很多，在不考虑各因素相互影响的前提下，举例说明了评估结果可能会出现不合理的情况，针对各因素之间的相互影响，提出了用灰关联度修订威胁隶属度的评估算法，在保持权重不变的情况下，同一个例子的评估结果分析表明，修订后的评估算法更合理。基于灰理论的威胁评估方法在可信度方面有了一定的提高。

Threat Evaluation Method Based on Grey Theory

Threat evaluation is not only beneficial to assign battle resources to draw a scientific conclusion, but is advantageous to preserve oneself and effective to hit enemy also. So it is necessary to build up a general threat evaluation system with high credibility. Many factors have effect on threat evaluation. Taking no account of factors affect mutually, an example was introduced to illustrate that the evaluation result may be unreasonable. Aimed at the problem that factors affect mutually in the process of threat evaluation, a kind of evaluation algorithm that revised threat membership degree according to grey relational degree was put forward. Under the condition of keeping the power coefficient constant, the analysis result of the same example indicated that the latter was more reasonable. The threat evaluation method based on grey theory has certain improvement in the range of credibility.
