基于预防性养护最佳策略的多周期决策法研究

摘要

针对目前国内尚不成熟的对道路进行长期预防性养护规划的问题，提出了预防性养护的多周期决策法，在不确定预防性养护措施的情况下，利用效益费用法来确定不同策略各阶段的最佳措施和实施时机。通过推荐的预防性养护策略与传统的零养护进行比较，验证各推荐养护策略的有效性，并以实体工程为例，确定不同策略水平下的最佳预防性养护策略。研究发现，多周期决策法是选择最佳预防性养护策略的有效方法。%For the domestic present immaturity problem of road long time preventive maintenance plan-ning,multi cycle decision of the preventive maintenance is put forward.Under the uncertainty condi-tion of the preventive maintenance measures,the benefit cost method is used to determine the best measures and the best implementation time of different strategies.Through comparing the recommen-ded preventive maintenance strategies with the traditional zero maintenance,the effectiveness of the preventive maintenance strategies is verified.Through a real project,the best strategy under different strategy level is determined.The study found that the multi cycle decision is an effective way to choose best preventive maintenance strategy.
