针对桥梁加固方案优选中存在诸多的灰色信息,提出了基于信息熵确定指标权值的模糊灰关联决策方法,结合工程实例,考虑桥梁加固中的各种因素进行综合评判,求得最优加固方案.该方法能够合理、有效的应用于桥梁加固方案优选,为桥梁加固方案决策的科学性提供了一个新的思路.
針對橋樑加固方案優選中存在諸多的灰色信息,提齣瞭基于信息熵確定指標權值的模糊灰關聯決策方法,結閤工程實例,攷慮橋樑加固中的各種因素進行綜閤評判,求得最優加固方案.該方法能夠閤理、有效的應用于橋樑加固方案優選,為橋樑加固方案決策的科學性提供瞭一箇新的思路.

Because of the gray informations in the optimal selection of reinforcement proposals for bridges, a fuzzy grey relational method based on information entropy is put forward. In this paper, the fuzzy grey relational method based on information entropy is applied to the selection of reinforcement proposals for bridges for seeking the best comprehensive result. The method, which is demonstrated to be reasonable and practical by real project, provides a new thinking to select reinforcement proposals for bridges more scientifically.
