摘要
考虑到灰色聚类指标的重要程度不同,采用模糊一致性矩阵来确定聚类指标的权重,提出了定权灰色聚类分析方法。运用该方法,选取公路安全评价指标,建立公路安全状况评价模型,对新疆公路历年交通安全状况进行评价。通过实例分析证明了该方法的简便性和实用性。
Considering the different important of the grey clustering index, the grey clustering analysis is improved by the fuzzy consistency matrix method. An evaluation model for highway safety is developed by means of the weighted grey clustering analysis theory. The conclusion of an example is reasonable to some extend, it can prove the convenience and practicability of the model in this paper.
