基于AHP法的沥青路面破损状况灰色聚类综合评价模型

GREY CLUSTERING EVALUATION MODEL OF COURSE TEACHING QUALITY BASED ON AHP

针对沥青路面破损状况评价方法的不足,本文依据灰色聚类分析原理,提供1种综合评价方法,使得评价过程客观公正,减少了评价结果的差异性。首先,利用建立评价指标体系,并利用AHP法确定各指标的权重系数,以此作为灰色聚类权;其次,利用统一标准确定白化值,以此建立白化函数;最后计算聚类向量,形成综合评价模型。通过结合实例进行综合评价,表明利用该模型可得到客观、可靠的沥青路面破损评价。

As problems such as the deficiency of the evaluation method for damage condition of asphalt concrete pavements, this arti- cle, based on the principle of grey cluster analysis, introduces a comprehensive method of evaluation, which improves the fairness and objectivity of the assessment procedure, reducing the difference within it. At first, we set up the assessment standard system and apply the AttP method to finalize the weight index, which are then used as the grey clustering weights; later, via a general standard we find out the explicit value, through which the definite weighted function is set up; finally, we calculate the clustering vectors, resulting in a comprehensive evaluation model. After a general evaluation through examples, we demonstrate that objective and reliable teaching eval- uations can be made via this model.
