  2. 1. Prognostics and Health Management of Engineering Systems for Operation and Maintenance Optimisation

    Author : Madhav Mishra; Matti Rantatalo; Kai Goebel; Kalevi Huhtala; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Prognostics and Health Management PHM ; Diagnostics; Prognostics; Bayesian; Hierarchical; L10; Prediction; Bearing; Li-ion battery; RUL; Particle filter; Model-based; Data-driven; Algorithms; Railway track geometry; Operation and Maintenance Engineering; Drift och underhållsteknik;

    Abstract : Prognostics and health management (PHM) is an engineering discipline that aims to maintain system behaviour and function and ensure mission success, safety and effectiveness. Prognostics is defined as the estimation of remaining useful life. READ MORE

  4. 2. Continuous improvements of complex technical systems : aspects of stakeholder requirements and system functions

    Author : Peter Söderholm; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kvalitetsteknik; Quality Technology and Management;

    Abstract : In today's society we are all strongly dependent on correct functions of technical systems. These systems tend to increase in both complexity and criticality, at the same time as they often have a rather long life. During this long life the stakeholders' requirements on the functions of the systems change. READ MORE

  5. 3. Data-driven battery aging diagnostics and prognostics

    Author : Yizhou Zhang; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; battery management system; remaining useful life; Lithium-ion batteries; machine learning.; state of health;

    Abstract : Lithium-ion (Li-ion) batteries play a pivotal role in transforming the transportation sector from heavily relying on fossil fuels to a low-carbon solution. But, as an electrochemical device, a battery will inevitably undergo irreversible degradation over time. READ MORE

  6. 4. Hybrid digital twins: A co-creation of data science and physics

    Author : Antonio Galvez; Diego Galar; Uday Kumar; Dammika Seneviratne; Dimitrios Kyritsis; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hybrid modelling; physics-based model; data-driven model; HVAC system; Railway; Drift och underhållsteknik; Operation and Maintenance;

    Abstract : Safety is more important than reliability or efficiency in railway, aerospace, oil & gas, and chemical industries. Regulations are very restrictive in sectors where safety is paramount. READ MORE

  7. 5. Model-based Prognostics for Prediction of Remaining Useful Life

    Author : Madhav Mishra; Jyoti Kumar Sinha; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance Engineering;

    Abstract : Prognostics and healthmanagement (PHM) is an engineering discipline that aims to maintain the systembehaviour and function, and assure the mission success, safety andeffectiveness. Health management using a proper condition-based maintenance (CBM)deployment is a worldwide accepted technique and has grown very popular in manyindustries over the past decades. READ MORE
