摘要
以最优化桥梁构件可靠度指标、维护费用和桥梁的日平均交通量为目标,考虑各个目标的权重系数,采用多目标最优指标(MOI),且基于帕累托最优理论和折衷规划法而建立的桥梁维护策略多目标优化方法,经实例证明可为基于维护目的而进行桥梁最优排序提供一个实用而有效的途径。
A multi-objective optimization method of bridge maintenance strategies based on Pareto optimization theory and compromise programming approach is introduced. The method is optimized for maintenance considering reliability index, maintenance costs, and average daily traffic （ADT）, as well as the weighted indices. Case proves that it can provide an effective and useful means for optimal sequence of bridge on the basis of the maintenance goal.
