摘要
为提高桥梁上部结构快速更换施工方案决策的科学性,建立多层多目标模糊决策优选模型。综合运用层次分析法、对抗性分析、模糊数学评判法等模糊数学决策分析理论,形成评估结果集,并根据Simpson的优势度指数对不同标度产生的排序结果进行合理优选,得到桥梁上部结构快速更换施工的推荐方案。采用工程实例对该决策优选模型的可靠性和适用性进行验证。
In order to improve the scientificity of the construction scheme decision for rapid replacement of bridge superstructure,a multi-layer and multi-objective fuzzy decision-making optimization model is established.The analytic hierarchy process(AHP),antagonistic analysis,fuzzy mathematical evaluation and other fuzzy mathematical decision-making analysis theories are comprehensively used to form the evaluation result set.According to Simpson's dominance index,the ranking results generated by different scales are reasonably optimized,and the recommended scheme for rapid replacement construction of bridge superstructure is obtained.Finally,the reliability and applicability of the model are verified by an engineering example.
