In order to improve the intelligent management level of subway track,a new intelligent subway track management system is designed.Naive Bayes Classifier,Logistic Regression Classifier and Support Vector Machine Classifier are designed respectively,and a track state prediction model based on Stacking ensemble algorithm is constructed.The equipment data,inspection data and maintenance data of XX Metro Line 1,2 and 6 from 2015 to 2021 are used to verify the validity of the model.Furthermore,an adaptive learning Markov decision process(AL-MDP)is introduced,and an optimization model of track maintenance decision based on Stacking-SVM is constructed.The model is used to sense the running state of the subway track and predict the abnormal state,and continuously learns the deterioration mechanism of the subway track through the process of adaptive learning,and provides the personalized and refined decision-making suggestion for the state warning and maintenance strategy of the track.Finally,the intelligent subway track management system is designed and implemented.After the introduction of the AL-MDP,the maintenance cost of the subway track is further reduced,and the operation status of the subway track can be grasped in real time.This research provides managers and workers with the refined,personalized and more scientific maintenance optimization decision,and achieves the dual precise control of maintenance cost and track safety.
