基于变权聚类法的路面使用性能综合评价

根据沥青混凝土路面使用性能评价状况,提出基于靶心贴近度的路面使用性能变权聚类方法.构造一种新的区间关联函数,提出"分类特征体现度越大,权重越大"的权重计算原理,将单指标关联函数的最大值作为其评价类的靶心坐标,依据样本与靶心的贴近度,对样本进行分类.该方法的有效性和合理性通过实例得到了验证.

Clustering Method Based on Variable Weight of the Pavement Performance Evaluation

Based on the current practice in bituminous concrete pavement performance evaluation,the cluster method of pavement performance in variable weight based on the degree of approaching to Target is presented in this paper.By constructing a new interval incidence function,the paper brings forward a principle of weight calculation which lies in that the clearer the symptom of the classified characteristic is,the bigger the weight is. The maximum value of incidence function for single index is used to be the eye of target.Also the paper categorizes the sample on the basis of the degree of approaching between samples and targets.Its reasonableness and effectiveness is proved by the example.
