摘要
依据目前高层建筑各种供水方式的特点,应用层次分析法的基本原理,建立了层次分析参数化随机模型,通过构建层次结构模型,确定难度系数和权重向量,得出各种供水方式的综合得分,选择出比较经济、合理的供水方式。该模型引入难度系数评分,克服了层次分析法中专家评分的主观性,得出的权向量是一致权重向量,具有无需进行一致性检验的优点。结果表明,应用该模型进行高层建筑供水方式的选择是一种科学、可靠的方法。
According to the characteristics of the present water supply modes of high buildings, principle of analytical hierarchy process （AHP） was applied to establish a model of AHP parameterized random in this paper. Through establishing hierarchical framework model, and determining the coefficient of difficulty and weight vector, integrated scores of different water supply modes were derived to select the economical and reasonable water supply mode. The method introduced appraisal coefficient of difficulty to overcome the subjectivity of experts. The right vector accorded with weight vector, so consistency test can be elided. The results showthat the method is a scientific and reliable method for selection of high--rise, water supply modes.
