多目标系统模糊优选理论在地铁施工中的应用

在地铁区间施工中,施工辅助方法的优劣,关系到整个工程的安全和经济。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,分析了影响地铁施工辅助措施方案决策的因素,建立地铁辅助施工方法选择的多目标模糊决策理论模型,并将此模型应用于实际工程中,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方案的多目标优化决策问题。

The application of multi-objective optimization system to assistant subway construction methods

In subway construction, the decision of auxiliary construction measures is a key factor which has much influence on worker's safety and corporation expenditure. Considering the properties of subway construction, using comprehensive fuzzy recognition and fuzzy relationship optimization, this paper analysed the factors that may influence the decision of auxiliary construction measures and presented the pattern of multi-decision making for multi-objective system. The pattern was applied to practical project. As a consequence, the problem of multi-objective decision system that was applied to auxiliary construction measures and affected by dozens of fuzzy factors and uncertain elements was successfully solved.
