In order to improve the performance of the sensors for data acquisition, an aerosoljet 3D printing technology is adopted to print customized sensors in this research. Compared with conventional bulk sensors, the customized sensors have a smaller size, higher accuracy, faster response time and could be printed onto the surface directly. However, as the line morphology of printed patterns has significant influence on the electrical properties, we need to investigate the influence of the process parameters on the line morphology and optimize the printed line quality. In this paper, we consider sheath gas flow rate and carrier gas flow rate as the key process parameters. The line roughness and line overspray are considered as the line quality indices. Latin hypercube sampling is adopted to fully explore the entire design space. And, a hybrid machine learning approach is proposed to analyze the relationship between line morphology and the process parameters, and finally an optimal operating window is identified based on the proposed approach.","PeriodicalId":202415,"journal":{"name":"2018 International Conference on Intelligent Rail Transportation (ICIRT)","volume":"165 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120987409","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}

In some industrial fields, model-based systems engineering (MBSE) methods have been widely developed and applied in recent years. Alstom and Bombardier have also attempted to adopt MBSE methods in their rolling stock product design to improve design quality, improve efficiency and reduce development risk. An attempt to design EMU based on the MBSE approach in China was introduced, taking the door control system as an example. The design is divided into three stages including requirement analysis, function breakdown and system architecture generation, which are interrelated with four design loops. The requirement and use case model, function model, as well as logical and physical architecture model of the door control system were built with SysML. Nine kinds of diagrams represent various view of the model, demonstrate the applicability of the MBSE method in the EMU designing. The application of SysML and Modelica in system modeling and strengthening MBSE is prospected.","PeriodicalId":202415,"journal":{"name":"2018 International Conference on Intelligent Rail Transportation (ICIRT)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128508972","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 heavy wear, long lifetime and adverse conditions the infrastructure is subject to gives rise to malfunctions and failures of components. Failure processes of individual components are reasonably well understood and have been analyzed using formal methods including fault trees and failure mode and effect analysis. Still, the understanding of the effects of infrastructure failures on the capacity and the performance of the entire network in operations remains limited to special cases or scenario-based approaches. In the present paper, we elaborate how formal methods used in risk assessment of individual components can be transferred to the analysis of the performance of the network. By identifying trains with their train paths we introduce a coupling between train operations and infrastructure asset management. We also discuss how a pre-defined level of service can be used to classify failure states or degraded modes of the system. Apart from a redundancy-based resilience analysis of network design the method can be used to identify critical elements and relevant failure scenarios, which can be used in timetabling applications.","PeriodicalId":202415,"journal":{"name":"2018 International Conference on Intelligent Rail Transportation (ICIRT)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127427469","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}

We argue in favor of keeping the layer of resilience associated with the train driver in the system through a train operator workplace that enables remote supervision, diagnosis and intervention of automated rolling stock out of a control center. Firstly, results from a simulator study featuring a prototypical remote workplace, developed in an iterative user-centered design process, show positive feedback in a sample of active German train drivers (n}=textbf{{20) in terms of acceptance ratings, usability assessment and perceived benefit to system resilience. Secondly, lower than optimal workload ratings in two experimental conditions of varying task load indicated free capacity for additional operational tasks throughout periods without direct manual interventions. Further insights on task load and workplace design as well as their limits are discussed, pointing out the direction for the next steps to be taken in the following design iterations. Future research needs to generate measures suitable for comparing system resilience between different grades of automation.","PeriodicalId":202415,"journal":{"name":"2018 International Conference on Intelligent Rail Transportation (ICIRT)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132972654","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}
