民用机场水泥道面维修计划的决策树模型

为使机场道面管理的辅助决策更加精确,满足智能化的要求,需要对现有网络级决策算法进行改进。本文基于信息熵的概念,提出了民用机场水泥道面维修计划的决策树模型。模型检验与评价结果表明,该模型结果准确性高,具有交叉有效性和自修正能力。使用上海浦东国际机场道面管理系统案例进行验证,可知与传统模型对比,决策树模型可以充分考虑道面使用性能、结构性能以及管理需求主观因素,决策结果更加符合工程实际。

Decision Tree Model of Civil Airport Cement Pavement Maintenance Program

In order to make the assistant decision of airport pavement management more accurate and meet the requirements of intelligence, the existing network-level decision making algorithms need to be improved. Based on the concept of information entropy, we present a decision tree model of civil airport cement pavement maintenance plan. The model test and evaluation results show that the model has high accuracy, cross-validation and self-correcting ability. We take Shanghai Pudong International Airport pavement management system as an example. Compared with traditional models, the decision tree model is proved to encompass multi-factors, like pavement performance, structural performance and subjective factors of management needs. The results demosnstrate that the proposed model is more fit the engineering in practice.
