Tutorials

One of the unique features of the PHM conferences is free technical tutorials on various topics in health management taught by industry experts. At the Second European PHM conference, tutorials will take place on Tuesday, July 8, and Wednesday, July 9. As educational events tutorials provide a comprehensive introduction to the state-of-the-art in the tutorial’s topic. Proposed tutorials address the interests of a varied audience: beginners, developers, designers, researchers, practitioners, and decision makers who wish to learn a given aspect of prognostic health management. Tutorials will focus both on theoretical aspects as well as industrial applications of prognostics. These tutorials reach a good balance between the topic coverage and its relevance to the community.

Tutorial Details

Tutorial Title: Consistency-Based Diagnosis

Anibal Bregon, Assistant Professor in Computer Science with the Department of Computer Science, University of Valladolid, Spain.
Abstract:The need for increased performance, safety, and reliability of complex engineering systems motivates the development of efficient fault diagnosis methodologies. Fault diagnosis is fundamental to reduce downtime and increase system availability through the life of the system. The process of fault diagnosis includes timely fault detection, quick fault isolation, and accurate fault identification. The focus of this tutorial is on model-based approaches to on-line fault detection, isolation, and identification (FDII) in complex dynamic systems. An advantage of using model-based techniques against other diagnosis approaches, like expert systems or machine learning, lies in the re-usability of models and the diagnostic algorithms. In particular, this tutorial will focus on the consistency approach to model-based diagnosis (known as consistency-based diagnosis, CBD), which has seen significant research activities from the Artificial Intelligence diagnosis (DX) community in the last two decades.

Tutorial Title: Particle Filters for Prognostics

Dr. Piero Baraldi, Assistant Professor of Nuclear Engineering at the department of Energy at the Politecnico di Milano, Italy
Abstract: Model-based prognostic methods use an explicit mathematical model of the degradation process to predict the future evolution of the degradation state and, thus, the RUL of the system. In practice, it is sometimes difficult to obtain an accurate RUL estimate since the degradation state of the system may not be directly observable and/or the measurements may be affected by noise and disturbances. In these cases, model-based estimation methods can be used to infer the dynamic degradation state and provide a reliable quantification of the estimation uncertainty on the basis of the sequence of available noisy measurements. Many approaches rely on Bayesian methods such as the exact Kalman filter, the Extended Kalman filter, Gaussian-sum filters, or the grid-based filters. Numerical approximations based on the Monte Carlo sampling technique, such as the Particle Filtering (PF) have gained popularity for their flexibility and ease of design. The aim of the tutorial is to illustrate the development and use of PF-based methods for the prediction of the Remaining Useful Life of a degrading component.
The first part of this tutorial will be devoted to the illustration of the theoretical basis of the PF method and its application to the prediction of the RUL of a degrading component.
In the second part of the tutorial, we will show different applications of the PF method to prognostics. The applications have differing degrees of knowledge about component behavior, and include different industrial components, such as structures, turbine blades, electric capacitors degrading, and nuclear power plant seawater.

Tutorial Title: Cyber-Physical Systems and Big Data Analytics for PHM Transformation

Dr. Jay Lee is Ohio Eminent Scholar, L.W. Scott Alter Chair Professor, and Distinguished University Professor at the University of Cincinnati, USA
Abstract: In today’s competitive business environment, companies are facing challenges in dealing with big data issues for rapid decision making for improved productivity. Many manufacturing systems are not ready to manage big data due to the lack of smart analytics tools. Germany is leading a transformation toward 4th Generation Industrial Revolution (Industry 4.0) based on Cyber-Physical System based manufacturing and service innovation. As more software and embedded intelligence are integrated in industrial products and systems, predictive technologies can further intertwine intelligent algorithms with electronics and tether-free intelligence to predict product performance degradation and autonomously manage and optimize product service needs,

The presentation will address the trends of industrial transformation in big data environment as well as the readiness of smart predictive informatics tools to manage big data to achieve transparency and productivity. First, industry transformation including Germany 4.0 and cyber-physical system will be introduced. Second, advanced prognostics technologies for smart product service systems with case studies will be presented. In addition, research advances in designing cyber-physical modeling for next-generation PHM will be discussed.

Abstract: The focus of this tutorial is on the area of prognostics of electronic systems. An overview of the state of the art will be presented. A review of the most common methods based on the data-driven prognostics approach will be presented. Special attention will be given to model-based prognostics methods for electronic components like power transistors and filter capacitors. This will include modeling of the degradation processes and how to make use of such models in order to assess the condition-based state of health and to predict remaining useful life. A discussion on how these model-based approaches relate to the electronics reliability tools will be presented making emphasis on difference and similarities but with the main objective of conveying how such approaches complement each other.
