| 摘 要： | 在城市地铁区间施工中，预支护方案的选择涉及诸多因素，本文基于地铁工程的特点，综合应用系统工程的模糊数学识别理论与模糊关系优选理论，建立地铁施工预支护方案选择的多目标多层次模糊决策理论模型，以方案的目标特征值作为最低层次的输入，依次以低层次的输出作为高层次的输入，对每一层次进行模糊计算，最后用级别向量的特征值对各个预支护方案进行排序，得出最优方案。通过算例计算得到比较理想的结果，有效地解决受众多模糊性和不确定性因素影响的地铁施工预支护方案的多目标优化决策问题．

| Abstract: | In subway construction, the choosing ofpre-support plan involves several factors. Considering the properties of subway construction, using fuzzy recognition and fuzzy relationship optimization of system engineering, this paper presents the multi-objective and multi-level fi~TD, decision-making theoretical model on the choosing of pre-support plan in subway construction. This paper takes the objective feature value of the plan as the lowest level input, and successively takes the output on a lower level as the input of the comparatively higher level to make approximately calculation on each level. At last, this paper arranges all the support plans in order with the level vector feature value to get the most optimum plan. Through example calculation the paper comes to a comparatively ideal conclusion and solved the multi-objective decision-making problem in pre-support plan of subway construction effectively, which is influenced by numerous fuzzy and indefinite factors. |
