One of the unique features of the PHM conferences is a full day of free technical tutorials on various topics in health management taught by industry experts. At the first European PHM conference, tutorials will take place on day one, Tuesday July 03. 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: Model Based Diagnosis

Tutorial Presenter: Peter Struss, Technical University of Munich

This tutorial will present theoretical foundations of consistency-based problem solving, principles and techniques of compositional modeling, and illustrative examples and industrial applications of the technology. The tutorial is intended towards researchers interested in knowledge-based technologies that are applicable to real-world problems and representatives from industry interested in innovative applications. Model-based systems are knowledge-based systems that are grounded in an explicit representation of this kind of 1st principles knowledge in terms of a behavior model of the system which is subject to problem solving. Tasks addressed by this technology include design, diagnosis and fault analysis, testing, and decision support. Important principles are representing the knowledge about a class of real-world systems as a library of models with a maximum of versatility and re-use to different system instances and for different tasks, and providing model-based problem solving engines that support or automate the exploitation of such models. The session will start with an Introduction to the Model-based Systems. Component-oriented (Qualitative) Modeling will be introduced next, followed by Consistency-based Diagnosis, and Test Generation. Other Tasks during the Product Lifecycle will also be presented with summary and presenter’s perspectives on the technology.

Peter Struss is a Professor of Computer Science at the Technical University of Munich since 1992, where he heads the Model-based Systems and Qualitative Modeling (MQM) group. Prior to that he worked in the Corporate R&D division of Siemens Corp., where he was in charge of the knowledge-based systems group. He stayed as a guest researcher at the Xerox Palo Alto Research Center several times and also at the International Computer Science Institute in Berkeley. His research interest is in Artificial Intelligence with a focus on the development of foundations and environments for modeling and model library building (qualitative modeling and multiple modeling, automated model abstraction), model-based problem solvers, esp. automated diagnosis, testing, failure-modes-and-effects analysis (logical foundations, inference engines, modeling of work processes), and model-based systems applications (such as in the automotive industries as a major focus, aeronautics, food packaging systems, structures (buildings), water treatment, ecological systems).Among various other professional activities, he is a member of the editorial board of the Journal of AI Research, the Artificial Intelligence Journal, and the International Journal of Prognostics and Health Management.

Tutorial Title: Fundamentals of Prognostics

Tutorial Presenters: Kai Goebel, NASA Ames Research Center, Abhinav Saxena, Research Scientist, SGT at NASA Ames Research Center

This Tutorial will focus on the concepts and basics of prognostics from condition-based systems health management viewpoint. Participants will be introduced to a prognostic framework that will contrast the differences with other techniques and philosophies of prognostics used in other domains. Examples will be used to illustrate various types of prediction scenarios and what does it take to set up a desired prognostic system. This will include discussions on significance of run-to-failure data, requirements and specifications generation for prognostics, prediction algorithms, post prognostic reasoning, etc. The session, then, will go into the details of setting up a prognostics problem and algorithm development using data-driven and model based approaches including data preprocessing and feature extraction steps. Discussion on prognostic performance evaluation and performance metrics will conclude the technical discussion followed by a general discussion on open research problems and challenges in prognostics.

Tutorial Title: State-of-the-Art Realization of Prognostics in Industry

Tutorial Presenters: Michel Schieber (Cassidian T&S, EADS company, France), Jean Baptiste Léger (Predict company, France), Benoît Iung (Lorraine University, France)

This tutorial will focus on prognostics considerations from an industrial viewpoint. Participants will be introduced to the prognostics framework in general (taking in consideration material already presented at the tutorial on prognostics fundamentals) which will underline key elements that are required to enable prognostics use as a main element in support of the maintenance challenge within the industrial community. The session will then present the results of an industrial survey conducted in France by the French PHM association DIAG21. It will provide practical insights into the following points, issued from different application domains:
- why companies are (or are not) currently deploying prognostics system
- What the methodological and technological hurdles against better deployment of prognostics in industry are
- What the expected added-value and benefits are.
Those experiences will be illustrated with both success stories and “non-optimal cases” on prognostics industrial implementation. Two complementary viewpoints, a theoretical one vs. a pragmatic one, will lead to a discussion on the degree to which prognostics can be realized within industry. The session will conclude with a discussion on future R&D work in industry and the scientific community needed to help improve the prognostic footprint in industry.
