摘要: 针对机场道面使用性能原始数据少、性状变化复杂的特点,将灰色系统理论与马尔可夫预测方法相结合,提出灰色-马尔可夫预测道面使用性能的方法,并结合实例详细分析描述了该方法的具体应用。首先建立GM(1,1)灰色拟和模型,对道面使用性能进行近期预测,补充样本数据信息;在此基础上采用最小二乘法替代传统的回归法确定马尔可夫状态转移概率矩阵,然后应用马尔可夫方法实现道面使用性能的中长期预测,并根据预测结果对模型精度进行敏感性分析。结果表明:该方法预测精度较高,能较好地解决道面使用性能预测中样本数据少、变异性大的问题,工程实用性较强,可作为机场道面使用性能预测的有效工具。

Abstract: Aiming at the lack of airport pavement original data and its stochastic variability, a new method that integrates Gray model and Markov chain is presented and is described in details by instance. Firstly, a GM (1, 1) model is built to conduct short-term PCI prediction and to expand the dataset. Secondly, least-square method is applied based on the expanded dataset to derive Markov state transition probability matrix. Using this matrix, middle and long term pavement performance is predicted by Markov chain. Thirdly, the precision sensitivity is analyzed,proving the high precision of this integrated model with big variability and sample data. This method can be used as an effective tool for airport pavement performance prediction.

Key words: airport pavement, performance prediction, Gray model, Markov prediction, pavement management
