摘要
针对影响装备的购置费用的因素很多,各因素并不同等重要,因素之间存在相互影响的关系,如何确定主要因素是建立预测模型的关键,论文提出采用粗糙集约简算法,对影响飞机购置费用的因素进行分析,并采用支持向量机进行预测,实例分析表明基于主要因素的预测模型要优于基于全部因素的预测模型。
Many factors influence the equipment purchase cost and each factor is not equally important.The factors influence each other.How to determine the main factor is the key to establish prediction model.The rough set reduction algorithm is applied to pretreat the factors which influence the plane purchase cost,and the support vector machine is used to build the prediction model.The example shows that the prediction model based on the main factors is superior to the model based on all factors.
