In this paper, a two-dimension Bayesian classifier, using rainfall data, is proposed to predict the debris flow. Firstly, part of historical rainfall and debris data are used to learn and train for classifier, which is a two-dimension classifier, then daily rainfall and recent five-day rainfall are used as the two dimensions inputs, on the basis of which the parameters of the classifier are confirmed; at last, in order to test the Bayesian classifier, the historical rainfall data is used for predicting debris flow, the predicted results are compared with actual results of debris flow occurrence, and the accuracy of classifier can be computed. The experiment shows that the two-dimension Bayesian classifier can obtain more correct prediction than one-dimension classifier, with the accuracy reaching 88.5%.","PeriodicalId":398100,"journal":{"name":"2015 IEEE Advanced Information Technology, Electronic and Automation Control Conference (IAEAC)","volume":"256 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124454805","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently, the cyclical and integral maintenance strategy was mainly adopted. In order to improve the equipment utilization and economic performance, a key equipment search algorithm based on complex network structure is presented in this paper, which gives a new way with differentiation for highway electromechanical maintenance. Based on the topological structure of mechanical and electrical system, the centrality, closeness centrality and distance centrality is combined as effective indicators of critical nodes. Moreover, in order to measure the topology of network and importance of neighboring nodes, mutual information of nodes in networks is calculated via the Markov chain interaction algorithm. By analysis on this project, different conditions lead to little difference of the research result, but acquire the same effect for critical nodes analysis. This paper proposes a new method to search the critical nodes in electromechanical system from the perspective of complex network, which provides a new theoretical basis for the reasonable design of highway electromechanical maintenance.","PeriodicalId":398100,"journal":{"name":"2015 IEEE Advanced Information Technology, Electronic and Automation Control Conference (IAEAC)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123985672","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It determines the tracked trajectory and the energy consumption of trains during the trip. Therefore, the optimization of recommended speed profile and the tracking strategy are regarded as two important means to achieve energy-efficient train operation between the successive stations. With considering the ATO tracking strategy, an optimization method of the recommended speed profile is proposed in this paper. Base on the approximate calculation, a discrete combination optimization model is formulated and a new MAX-MIN ant system (MMAS) is taken as the core algorithm. With the fixed speed tracking strategy, this method achieves the recommended speed profile with optimized energy consumption and a perfect running punctuality along the actual tracked trajectory. The switching times of operation during the cruising phase is reduced by integrating the drivers' experience, which also reduces the energy consumption of train running between stations. The case results based on Beijing Yizhuang Metro Line in China verify the effectiveness of the proposed method, which has a good performance on energy-efficient train operation.","PeriodicalId":398100,"journal":{"name":"2015 IEEE Advanced Information Technology, Electronic and Automation Control Conference (IAEAC)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122437115","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
