摘　　要：讨论了综合优选大跨空间钢结构方案的多目标决策问题,采用层次分析法建立递阶层次结构,运用改进的层次分析法合理地确定指标因素的权重,用模糊数学理论和集值统计原理把指标量化,最后利用理想点法确定最优的结构方案。This paper discusses the multi-objective decision making of the comprehensive optimum design for long-span spatial steel structure scheme. It uses the Analytic Hierarchy Process to establish hierarchical structure, and the Improved Analytic Hierarchy Process to reasonably determine the weight of indexes, and then adopts fuzzy mathematics theory and setting value statistic principle to quantify the indexes. Finally the ideal point method is used to determine the optimum structure scheme.

关 键 词：层次分析法 模糊数学 集值统计 理想点法 大跨空间钢结构
