基于粗糙集的作战飞机总体设计方案综合评估

Comprehensive evaluation of combat aircraft conceptual design on rough set

针对作战飞机总体设计方案综合评估法权系数确定过于依靠专家主观判断和经验的不足,应用粗糙集理论对典型的第三代以上作战飞机机型的各种指标数据进行挖掘,利用信息熵概念求得各指标的属性重要度,从而确定各指标的权系数。应用实例表明,该方法是客观的,可行的和有效的。

Focus on the deficiency that traditional weight determination method relies on subjective judgement and experiences of the experts excessively,the rough set theory is used to determine the index data of the third generation combat aircraft types,the conception of information entropy is used to get the important degree of the attributes,thus,the weight coefficient is given.The example shows that the approach is objective,feasible and effective.
