基于云重心评价法的空袭目标威胁程度评估

Air-attack Targets Threat Evaluation on MCGC

传统的空袭目标威胁度评估一般采用定性评估方法,而对于精确的定量评估,目前尚缺有效的方法;云理论是一种用于处理不确定性和含糊性知识的数学工具,可实现概念与数据之间的相互转换;针对空袭目标威胁度的问题,论文通过确定空袭目标威胁程度判断准则集,结合云理论的有关知识,建立各指标的云模型及其多维加权综合云的重心表示,最后应用云重心评价方法给出目标威胁度的定量评估值,从而为防空作战指挥员对空情威胁作出快速准确判断提供了科学的依据。

Generally, the traditional operational effectiveness evaluation of air--attack targets threat uses the qualitative approach, however, there aren＇t any effective methods to quantitative evaluation. Cloud theory has been proved to be an excellent mathematical tool for dealing with uncertain and vague description of objects, and it can realize the transforms between qualitative concepts and their quantitative expression. Against the problem of the traditional operational effectiveness evaluation of air--attack targets threat, the paper ascertains the establishment of guide lines of the air target threat. And based on the cloud theory, the theory of membership cloud, concepts of multi--dimension synthetic cloud and its gravity centre （GC） are proposed, which helps the operation commander of air defense to make a fast and accurate decision.
