桥梁设计方案优选过程中的模糊综合评价

Comprehensive Fuzzy Evaluation in the Optimal Selection of Bridge Designs

桥梁设计方案在优选过程中,涉及到的影响因素很多。以模糊数学为基础,采用定性和定量相结合的方法建立多目标决策模型,通过综合评价进行方案优选,结合实例考虑方案选择中的各种因素进行综合评判,求得最佳桥梁方案。

In the course of the optimal selection of the bridge designs, many influencing factors are involved. Based on fuzzy mathematics, this paper establishes a model of multi-target decision by the method of combining quantitative analysis with the qualitative, and selects the optimal plan by the comprehensive evaluation.
