摘要
预养护对策选择是一个多属性决策问题,但由于缺乏信息,决策往往由专家主观判定,结果依赖于专家的工程经验.在全面分析公路沥青路面预养护决策影响因素的基础上,建立了系统的评价指标体系,并运用层次分析法确定了各个指标的权重,通过专家打分来量化不同预养护对策的各个评价指标,采用物元分析方法对不同预养护方案进行综合排序,从而确定最佳预养护措施.该模型克服了传统决策方法中存在的主观因素过多、权重不确定等问题.结合上海市A20公路预养护工程进行的实例研究证明了模型的合理性与有效性.研究成果可为沥青路面预养护决策提供科学的依据.
Pavement preventive maintenance treatment selection is a problem of multi-attribute decision-making. However, the decision - making is often a subjective judgment due to lack of information. The index system for evaluating pavement preventive maintenance treatment has been established based on the comprehensive analysis of factors affecting the decision-making. Each evaluation indicator has assigned a decimal weighing factor between 0 and 1 by employing the analytic hierarchy process. After quantification of each evaluation indicator for different treatments, the optimal preventive maintenance treatment is selected by the aid of the synthetic order of scenarios which is determined by the matter-element analysis. The decision-making model has overcome the defection of including over-many subjective factors and inaccurately weighing them in the traditional method. Combined with the project of pavement preventive maintenance for A20 highway in Shanghai, a case study has been done and the rationality and availability of the model has also been demonstrated. The result provides decision makers with a scientific support in their decision-making.
