摘要
将桥梁的使用期离散化为一等时段时间序列 ,从而应用马尔柯夫过程模型建立了描述性能变化的状态方程 ,确定了最佳维修方式并以桥梁在使用期内的期望效益最大为目标 。
The using periods of the bridges are divided into a time sequence of equal period of time and by using the model of Markov process, a state equation of properties is established in this paper. The best method of maintenance and overhaul is made, and at the same time, taking the maximum total expected benefit within the using period of the bridge as an object, a mathematical model determining the optimal maintenance strategy is built. All of this provides the managers a scientific method for decision making.
