摘　　要：将灰色关联分析法应用于公路网综合评价,且采用离差最大化方法确定权重,克服了人为主观因素的影响,使结果更加客观公正合理,并在此基础上对评价结果进行了灰色聚类分析,使综合评价得到进一步研究。方法运算简单,直观适用。In this paper, the method of Grey Relational Analysis is applied in the comprehensive evaluation for highway network. And the weighting coefficients are determined by the method of maximizing deviations. It can overcome the subjective influence of decision-makers, and results are more impersonal, just and reasonable. On this base, the grey clustering analysis for evaluation results is given, and the further researches on the comprehensive evaluation are carried out. A case study shows that this method is feasible, simple and practicable.
