Furthermore, the analysis process of the new GO method is formulated. Finally, the dynamic availability analysis of HTOSS is conducted by the GO method. And the result is compared with the result of system considering CCF, and the result of system without considering CCF and maintenance correlation. The results show that the CCF and maintenance correlation are not ignored for reliability analysis of such system. All in all, this study not only widens the application of GO method. But it also provides guidance and an approach for reliability analysis of repairable systems with two-unit parallel structure considering CCF and maintenance correlation.","PeriodicalId":403595,"journal":{"name":"2019 International Conference on Sensing, Diagnostics, Prognostics, and Control (SDPC)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115600546","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}

As is known to all, each label might possess its own peculiarities, such as LIFT algorithm, i.e. multi-label learning with Label-specific Features. It constructs feature by performing cluster techniques based on negative and positive training samples of each label. However, the main drawback of this kind of algorithm is the large amounts of irrelevant features or redundant features in its feature space. To solve this problem, this paper puts forward an effective algorithm named LEFS, i.e. multi-label Feature Selection based on Label-specific features with fuzzy Entropy. The approaches proposed are examined on the two realistic multi-label benchmark data sets, which are compared with several multi-label learning approaches. A few features are selected from original features to fed classifier, but they remain the same or even slightly improve accuracy from 91.82% to 92.49% on data set- Medical. Results of another data sets are similar to that of the Medical. Experiment results show that these approaches can not only decrease the dimension of the construct features, but also gain an effective classification performance compared with three well-established multi-label learning approaches.","PeriodicalId":403595,"journal":{"name":"2019 International Conference on Sensing, Diagnostics, Prognostics, and Control (SDPC)","volume":"95 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124741834","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}

According to the historical data of the monitoring parameters, the degradation trend of the gas turbine and parameters can be obtained to achieve the purpose of predicting the remaining useful life, and provide the basis for subsequent fault diagnosis and maintenance work. Firstly, the fuzzy analytic hierarchy process (FAHP) is used to construct the calculation model of gas turbine HD. Secondly, the acceleration change point analysis method is combined with the kernel density estimation method to determine the gas turbine fault threshold. On this basis, this paper proposes a new prediction algorithm-- the splicing prediction algorithm based on HD and establishes the RUL prediction model of the gas turbine. Finally, the test data set in C-MAPSS is used for case analysis, and the predicted RUL is compared with the real value to obtain the prediction accuracy. The results show that the proposed prediction algorithm can predict the RUL of some data that meets the degradation detection, and the prediction accuracy is 86.67%, which proves the validity and feasibility of the proposed method.","PeriodicalId":403595,"journal":{"name":"2019 International Conference on Sensing, Diagnostics, Prognostics, and Control (SDPC)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124800002","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}

The machine learning algorithm of support vector classifier is used to predict the fault of the fire control computer and sensor subsystem. In order to better carry out the fire control system health management, the fault prediction of the fire control system not only stays in the identification of the \"normal\" and \"fault\" states, but also distinguishes different types of fault states. The least squares support vector multiclassifier based on decision directed acyclic graph is selected for prediction. The improved separation measure is introduced to improve the decision directed acyclic graph, which reduces the error caused by improper initial sequence. The particle swarm optimization algorithm is used to optimize the parameters of the least squares support vector classifier, which improves the classification accuracy.

However, the calculation of gas path parameter deviations is complicated and the calculation models are also mastered by the original equipment manufacturer (OEM), which makes it burdensome for airlines to independently analyze the gas path performance of the aeroengine. At present, airlines have accumulated a large number of samples of gas path parameter deviations, which makes it possible to establish a regression model between gas path parameters and its deviations by data-driven method. In order to enhance the analysis capability of airline in gas path performance, we apply the residual learning blocks to the back propagation (BP) neural network based on the learning mechanism of the residual networks (ResNets). According to the solution characteristics of gas path parameter deviations, the regression models for the gas path parameter deviations are established based on Res-BP neural network. The screening for nonlinear independent variables of regression model is carried out by mean impact value (MIV) method, and then the input and output of Res-BP neural network can be determined. After the regression model training, the test set is tested by the proposed regression model. By comparing with BP neural network regression model and traditional regression model, the proposed regression model manifests higher prediction accuracy and generalization performance on the three key gas path parameter deviations, which is of great guiding significance for the aero-engine condition monitoring.","PeriodicalId":403595,"journal":{"name":"2019 International Conference on Sensing, Diagnostics, Prognostics, and Control (SDPC)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128987098","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}
