摘　　要：分别运用马尔可夫链和半马尔可夫过程为桥梁管理系统建立桥梁退化模型,并提出程序流程。通过退化模型可以对桥梁状态进行预测,其预测结果直接为桥梁管理工作人员提供决策辅助,也可以作为桥梁决策优化的基础,而当桥梁状态数据不充分时,桥梁状态预测过程可以为桥梁管理系统采集数据提供必要的指导。The article proposes a method to develop bridge deterioration model in bridge manage ment system by Markov Process or Semi-Markov Process, and program for them as well. We can predict bridge future condition through the bridge deterioration model. Its result can help the bridge manager to make decisions, and also can be the foundations for bridge decision optimization. When bridge condition data are not enough, its procedure can be an instruction for the data collection of bridge management system.
