基于层次分析法的工程材料优选综合评价

Comprehensive Evaluation for Optimummly Choosing Engineering Material with Analytic Hierarchy Process(AHP)

从分析影响建筑工程材料选择的因素及其构成关系入手,根据目前工程材料选择的经验,运用层次分析法对工程材料优选进行评价,并提出全面的定量化和定性化的层次结构评价模式和总体评价方法。其基本评价的步骤为首先构建工程材料优选的层次分析结构模型及判断矩阵,然后进行层次排序,并对判断矩阵进行一致性检验,在定性、定量指标转换的基础上形成评价方法。工程实例表明该方法简易可行,结论符合实际。

Based on engineering experience, this paper analyzes the affecting factors of engineering material selection, uses the principle of Analytic Hierarchy Process to evaluate the optimum choosing of building material, and proposes the construction of the evaluation pattern and the overall evaluation method on quantity and quality. The basis steps are firstly to build the structure model and judge matrix about engineering material selection, then carry on an order and consistency inspection of judging matrix, at last form the evaluation method on the basis of index changing on quantity and quality. An engineering example shows that this method is feasihable, it can meet the demand of evaluation practice. 9 tabs, 1 fig, 6 refs.
