最优化技术在决策分析中占着极重要的位置。层次分析法(AHP)是将决策总是有关的元素分解成目标、准则、方案等层次,在此基础之上进行定性和定量分析的决策方法。基于群组层次分析法的评价指标体系设计方法,它既能体现层次分析法(AHP)的优点,又能较好地弥补层次分析法AHP法的不足。本文以厦门海底隧道为工程背景,就海底隧道埋深提出了基于群组层次分析法。拟请一组专家对影响海底隧道厚度的因素进行评价,根据专家的判断能力,给出判断力权值,得到最小岩石覆盖厚度的重要性因子,给出不同方法的权值,经加权分析后最终确定最小岩石覆盖厚度。
Optimization technology plays a very important role in decision analysis. Analytic Hierarchy Process (AHP) is the decision-making method of qualitative and quantitative analysis based on the decomposition of the elements that are always relevant in decision-making into objectives, criteria and programs. Based on AHP method, this method can not only reflect the advantages of Analytical Hierarchy Process (AHP), but also make up for the deficiency of Analytic Hierarchy Process (AHP). In this paper, Xiamen submarine tunnel as the engineering background, the depth of the subsea tunnel proposed based on the group level analytic method. A group of experts is expected to evaluate the factors influencing the thickness of the subsea tunnel. According to the judgment ability of the experts, the weight of judgment is given, and the importance factor of the minimum rock cover thickness is obtained. The weights of different methods are given. After weighted analysis Ultimately determine the minimum rock cover thickness.
