  text: "Predicting the remaining useful life of technical \r\nsystems has gained
    significant attention in recent years due to \r\nincreasing demands for extending
    the lifespan of degrading system \r\ncomponents. Therefore, already used systems
    are retrofitted by \r\nintegrating sensors to monitor their performance and \r\nfunctionality,
    enabling accurate diagnosis of their condition and \r\nprediction of their remaining
    useful life. One of the main \r\nchallenges in this field is identified in the
    missing data from the \r\ntime where the retrofitted system has already run but
    without \r\nbeing monitored by sensors. In this paper, a novel approach for \r\nthe
    combined diagnostics and prognostics of retrofitted systems is \r\nproposed. The
    methodology aims to provide an accurate diagnosis \r\nof the system’s health state
    and estimation of the remaining useful \r\nlife by a combination of a machine
    learning and expert knowledge. \r\nTo evaluate the effectiveness of the proposed
    methodology, a case \r\nstudy involving a retrofitted system in an industrial
    setting is \r\nselected and applied. It is demonstrated that the approach \r\neffectively
    diagnose the current system’s health state and \r\naccurately predict its remaining
    useful life, thereby enabling \r\npredictive maintenance and decision-making.
    Overall, our \r\nresearch contributes to advancing the field of condition \r\nmonitoring
    for retrofitted systems by providing a comprehensive \r\nmethodology that addresses
    the challenge of missing data."

  text: "Aufgrund der Fortschritte der Digitalisierung finden Systeme zur Zustandsüberwachung
    vermehrt Einsatz in der Industrie, um durch eine zustandsbasierte oder eine prädiktive
    Instandhaltung Vorteile, wie eine verbesserte Zuverlässigkeit und geringere Kosten
    zu erzielen. Dabei beruhen Zustandsüberwachungssysteme auf den folgenden Bausteinen:
    Sensorik, Datenvorverarbeitung, Merkmalsextraktion und -auswahl, Diagnose bzw.
    Prognose sowie einer Entscheidungsfindung basierend auf den Ergebnissen. Jeder
    dieser Bausteine erfordert individuelle Einstellungen, um ein geeignetes Zustandsüberwachungssystem
    für die jeweilige Anwendung zu entwickeln. Eine offene Fragestellung im Bereich
    der Zustandsüberwachung ergibt sich aufgrund der Unsicherheit der Zukunft, die
    sich in den zukünftigen Betriebs- und Umgebungsbedingungen zeigt. Diese Unsicherheit
    gilt es in allen Bausteinen zu berücksichtigen.\r\nDieser Beitrag konzentriert
    sich auf den Baustein Merkmalsextraktion und -selektion, mit dem Ziel anhand geeigneter
    Merkmale eine Prognose der nutzbaren Restlebensdauer mit hoher Genauigkeit realisieren
    zu können. Daher werden geeignete Merkmale aus dem Zeitbereich und daraus abgeleitete
    Zustandsindikatoren für die Restlebensdauerprognose von technischen Systemen vorgestellt.
    Dabei sind Zustandsindikatoren Kenngrößen zur Beobachtung des Zustands der kritischen
    Systemkomponenten. Anhand dreier Anwendungsbeispiele wird ihre Eignung evaluiert.
    Dabei werden Daten aus Lebensdauerversuchen unter instationären Betriebs- und
    Umgebungsbedingungen ausgewertet. Die auftretenden Unsicherheiten der Zukunft
    werden somit berücksichtigt. Die Beispielsysteme beruhen auf Gummi-Metall-Elementen
    und Wälzlagern. Aus den generierten Ergebnissen lässt sich schließen, dass die
    Zustandsindikatoren aus der betrachteten Zeitreihen-Toolbox auch unter unbekannten
    Betriebs- und Umgebungsbedingungen robust sind.\r\n"

  text: "Due to the advances in digitalization, condition monitoring systems have
    found numerous applications in the industry due to benefits such as improved reliability
    and lowered costs through condition-based or predictive maintenance. Condition
    monitoring systems typically involve elements, such as data acquisition via suitable
    sensors, data preprocessing, feature extraction and selection, diagnostics, prognostics
    and (maintenance) decisions based on diagnosis or prognosis. For the application-specific
    development of a suitable condition monitoring system, each of these elements
    requires individual settings. Due to the uncertainty of the future, an open question
    arises in the condition monitoring field, which is reflected in unknown future
    operating and environmental conditions. This uncertainty needs consideration in
    all elements of a condition monitoring system.\r\nThis article focuses on feature
    extraction and selection, building on the hypothesis that the remaining useful
    life of a technical system can be predicted with high accuracy utilizing suitable
    features. In this article, health indicators derived from time-domain features
    that permit the monitoring of the health of critical system components are presented
    for predicting the remaining useful life of technical systems. Three distinct
    application examples based on rubber-metal elements and rolling-element bearings
    are evaluated to validate the suitability of the presented methods. Experimental
    data from accelerated lifetime tests conducted under non-stationary operating
    and environmental conditions are considered to take possible future uncertainties
    into account. It can be concluded from the acquired results that health indicators
    derived from the presented time series toolbox are robust to varying operating
    and environmental conditions.\r\n"

  text: <jats:p>While increasing digitalization enables multiple advantages for a
    reliable operation of technical systems, a remaining challenge in the context
    of condition monitoring is seen in suitable consideration of uncertainties affecting
    the monitored system. Therefore, a suitable prognostic approach to predict the
    remaining useful lifetime of complex technical systems is required. To handle
    different kinds of uncertainties, a novel Multi-Model-Particle Filtering-based
    prognostic approach is developed and evaluated by the use case of rubber-metal-elements.
    These elements are maintained preventively due to the strong influence of uncertainties
    on their behavior. In this paper, two measurement quantities are compared concerning
    their ability to establish a prediction of the remaining useful lifetime of the
    monitored elements and the influence of present uncertainties. Based on three
    performance indices, the results are evaluated. A comparison with predictions
    of a classical Particle Filter underlines the superiority of the developed Multi-Model-Particle
    Filter. Finally, the value of the developed method for enabling condition monitoring
    of technical systems related to uncertainties is given exemplary by a comparison
    between the preventive and the predictive maintenance strategy for the use case.</jats:p>

  text: 'Remaining useful lifetime (RUL) predictions as part of a condition monitoring
    system are focused in more and more research and industrial applications. To establish
    an efficient and precise estimate of the RUL of a technical product, different  uncertainties  have  to  be  handled.  To  minimize  the  uncertainties  of  the  RUL  estimation,  a  reliable
    and accurate prognostic approach as well as a good failure threshold are important.
    Regarding the failure threshold, most often  an  expert  sets  a  fixed  failure  threshold.  However,  neither  the  a  priori  known  failure  threshold  nor  a  fixedthreshold
    value are feasible in every application. Especially in the case of varying characteristics
    of the monitored system, an adaptive failure threshold is of great importance
    concerning the accuracy of the RUL estimation.  Rubber-metal-elements, which are
    used in a wide range of applications for vibration and sound isolation, are mon-itored
    by thermocouples to allow for lifetime predictions. Therefore, the element’s state
    is described by its temper-ature during its service life. Aiming to establish
    accurate RUL predictions of a rubber-metal-element, uncertainties due to nonlinear
    material characteristics and changing operational conditions have to be considered.
    Consequently, different temperature-based failure threshold definitions are implemented
    and compared within a particle filtering approach. '

  text: This paper presents a comparison of a number of prognostic methods with regard
    to algorithm complexity and performance based on prognostic metrics. This information
    serves as a guide for selection and design of prognostic systems for real-time
    condition monitoring of technical systems. The methods are evaluated on ability
    to estimate the remaining useful life of rolling element bearing. Run-to failure
    vibration and temperature data is used in the analysis. The sampled prognostic
    methods include wear-temperature correlation method, health state estimation using
    temperature measurement, a multi-model particle filter approach with model parameter
    adaptation utilizing temperature measurements, prognostics through health state
    estimation and mapping extracted features to the remaining useful life through
    regression approach. Although the performance of the methods utilizing the vibration
    measurements is much better than the methods using temperature measurements, the
    methods using temperature measurements are quite promising in terms of reducing
    the overall cost of the condition monitoring system as well as the computational
    time. An ensemble of the presented methods through weighted average is also introduced.
    The results show that the methods are able to estimate the remaining useful life
    within error bounds of +-15\%, which can be further reduced to +-5\% with the
    ensemble approach.

  text: Application of prognostics and health management (PHM) in the field of Proton
    Exchange Membrane (PEM) fuel cells is emerging as an important tool in increasing
    the reliability and availability of these systems. Though a lot of work is currently
    being conducted to develop PHM systems for fuel cells, various challenges have
    been encountered including the self-healing effect after characterization as well
    as accelerated degradation due to dynamic loading, all which make RUL predictions
    a difficult task. In this study, a prognostic approach based on adaptive particle
    filter algorithm is proposed. The novelty of the proposed method lies in the introduction
    of a self-healing factor after each characterization and the adaption of the degradation
    model parameters to fit to the changing degradation trend. An ensemble of five
    different state models based on weighted mean is then developed. The results show
    that the method is effective in estimating the remaining useful life of PEM fuel
    cells, with majority of the predictions falling within 5\% error. The method was
    employed in the IEEE 2014 PHM Data Challenge and led to our team emerging the
    winner of the RUL category of the challenge.
