These challenges can critically impact assets in the distribution grid—e.g., switchgears—intensifying the need to plan, conduct, and manage the maintenance of such assets. Predictive maintenance strategies that analyze assets' current and historical condition data have been discussed as promising approaches toward that end. However, the extant research focuses on designing and improving analytical algorithms or information technology (IT) artifacts while not considering how a maintenance service is cocreated by companies with IT. This research article posits that IT and service must be aligned closely, presenting an ensemble artifact comprising a digital industrial platform and a smart service system for predictive maintenance on the distribution grid. The artifact is evaluated by conducting a willingness-to-pay analysis with asset operators, documenting their demand for condition monitoring and predictive maintenance as an integrated solution, although they still struggle with even getting the condition data of their assets. Building on these results, we formalize the knowledge in the form of design principles and implications for managing the maintenance of critical assets in the distribution grid.","lang":"eng"}],"publication":"IEEE Transactions on Engineering Management","title":"Predictive Maintenance on the Energy Distribution Grid—Design and Evaluation of a Digital Industrial Platform in the Context of a Smart Service System","date_created":"2024-01-19T11:47:56Z","publisher":"Institute of Electrical and Electronics Engineers (IEEE)","year":"2024","quality_controlled":"1","file_date_updated":"2024-04-18T12:26:27Z","article_type":"original","user_id":"82872","_id":"50649","project":[{"grant_number":"03E16012F","name":"FLEMING: FLEMING - Flexible Monitoring- und Regelsysteme für die Energie- und Mobilitätswende im Verteilnetz durch Einsatz von Künstlicher Intelligenz","_id":"651"}],"status":"public","type":"journal_article","doi":"10.1109/tem.2024.3352819","volume":71,"author":[{"first_name":"Philipp","full_name":"zur Heiden, Philipp","id":"64394","last_name":"zur Heiden"},{"first_name":"Jennifer","full_name":"Priefer, Jennifer","id":"82872","last_name":"Priefer"},{"first_name":"Daniel","id":"59677","full_name":"Beverungen, Daniel","last_name":"Beverungen"}],"date_updated":"2024-11-11T09:50:34Z","intvolume":"        71","page":"3641-3655","citation":{"mla":"zur Heiden, Philipp, et al. “Predictive Maintenance on the Energy Distribution Grid—Design and Evaluation of a Digital Industrial Platform in the Context of a Smart Service System.” <i>IEEE Transactions on Engineering Management</i>, vol. 71, Institute of Electrical and Electronics Engineers (IEEE), 2024, pp. 3641–55, doi:<a href=\"https://doi.org/10.1109/tem.2024.3352819\">10.1109/tem.2024.3352819</a>.","short":"P. zur Heiden, J.

The aim of this thesis is the development of a condition monitoring system of rubber-metal-elements. Due to the viscoelasticity and the complex degradation behavior of the elements, they are currently maintained preventively. During lifetime tests of the rubber-metal-elements, three measurement quantities are acquired. Thereby, temperature is identified as the most suitable measurement quantity to describe the rubber-metal-elements state. The accuracy of a condition monitoring system is generally influenced by various uncertainties. To consider available uncertainties within the behavior and the degradation of the elements, the particle filter, a state-of-the-art model-based method for predicting remaining useful life, is enhanced and employed. The results prove that the developed condition monitoring system enables an increased utilization of rubber-metal-elements in real applications through predictive maintenance. This thesis provides the basis for future concepts of predictive maintenance for rubber-metal-elements. Moreover, it is recommended to take uncertainties into account at an early stage of the development process of condition monitoring systems.","lang":"eng"}],"author":[{"first_name":"Amelie","last_name":"Bender","full_name":"Bender, Amelie","id":"54290"}],"date_created":"2021-04-15T10:29:53Z","supervisor":[{"id":"21220","full_name":"Sextro, Walter","last_name":"Sextro","first_name":"Walter"},{"first_name":"Stefan","full_name":"Bracke, Stefan","last_name":"Bracke"}],"date_updated":"2023-09-15T12:22:50Z","publisher":"Shaker","doi":"10.17619/UNIPB/1-1084","title":"Zustandsüberwachung zur Prognose der Restlebensdauer von Gummi-Metall-Elementen unter Berücksichtigung systembasierter Unsicherheiten","citation":{"ama":"Bender A. <i>Zustandsüberwachung zur Prognose der Restlebensdauer von Gummi-Metall-Elementen unter Berücksichtigung systembasierter Unsicherheiten</i>.

Due to the ease of implementation, interpretation and transparency to both domain experts and non-experts, a rule-based method is proposed in this paper, for prognostics and health management (PHM) and specifically for diagnostics. The proposed method utilizes the most relevant sensor signals acquired via feature extraction and selection techniques and expert knowledge. As a case study, the presented method is evaluated on data from a real-world quality control set-up provided by the European prognostics and health management society (PHME) at the conference’s 2021 data challenge.

This can be used to assure reliability by controlling system behavior to reach a pre-defined lifetime. By using such closed loop control, the margin of error of useful lifetime of an individual system is lowered. It is also possible to change the pre-defined lifetime during operation, by adapting system behavior to derate component usage. When planning maintenance actions, the remaining useful lifetime of each individual system has to be taken into account. Usually, stochastic properties of a fleet of systems are analyzed to create maintenance plans. Among these, the main factor is the probability of an individual system to last until maintenance. If condition-based maintenance is used, this is updated for each individual system using available information about its current state. By lowering the margin of error of useful lifetime, which directly corresponds to the time until maintenance, extended maintenance periods are made possible. Also using reliability-adaptive operation, a reversal of degradation driven maintenance planning is possible where a maintenance plan is setup not only according to system properties, but mainly to requirements imposed by maintenance personnel or infrastructure. Each system then adapts its behavior accordingly and fails according to the maintenance plan, making better use of maintenance personnel and system capabilities at the same time. In this contribution, the potential of maintenance plan driven system behavior adaptation is shown. A model including adaptation process and maintenance actions is simulated over full system lifetime to assess the advantages gained."}],"status":"public","_id":"9949","user_id":"55222","department":[{"_id":"151"}],"keyword":["Adaptive systems","Reliability analysis","Availability","Adaptive control","Maintenance","Self-optimizing systems","Self-optimizing control","Stochastic Petri-nets"],"language":[{"iso":"eng"}]},{"publication":"International Journal of Prognostics and Health Management","type":"journal_article","abstract":[{"lang":"eng","text":"This study presents the methods employed by a team from the department of Mechatronics and Dynamics at the University of Paderborn, Germany for the 2013 PHM data challenge.

Due to close correlation of parametric data of different problems, this approach produced high misclassification rate. Event-based decision trees were then constructed to identify problems associated with particular events. To distinguish between problems associated with events that appeared in multiple problems, support vector machine (SVM) with parameters optimally tuned using particle swarm optimization (PSO) was employed. Parametric data was used as the input to the SVM algorithm and majority voting was employed to determine the final decision for cases with multiple events. A total of 165 SVM models were constructed. This approach improved the overall score from 21 to 48. The method was further enhanced by employing an ensemble of three data driven methods, that is, SVM, random forests (RF) and bagged trees (BT), to build the event based models. With this approach, a score of 51 was obtained . The results demonstrate that the proposed event based method can be effective in maintenance action recommendation based on events codes and parametric data acquired remotely from an industrial equipment."}],"status":"public","_id":"9808","department":[{"_id":"151"}],"user_id":"55222","keyword":["maintenance decision","Bagged trees","Decision trees","PSO-SVM","Random forests"],"language":[{"iso":"eng"}],"quality_controlled":"1","issue":"2","year":"2013","intvolume":"         4","citation":{"bibtex":"@article{Kimotho_Sondermann-Wölke_Meyer_Sextro_2013, title={Application of Event Based Decision Tree and Ensemble of Data Driven Methods for Maintenance Action Recommendation}, volume={4}, number={2}, journal={International Journal of Prognostics and Health Management}, author={Kimotho, James Kuria and Sondermann-Wölke, Chritoph and Meyer, Tobias and Sextro, Walter}, year={2013} }","mla":"Kimotho, James Kuria, et al. “Application of Event Based Decision Tree and Ensemble of Data Driven Methods for Maintenance Action Recommendation.” <i>International Journal of Prognostics and Health Management</i>, vol. 4, no. 2, 2013.","short":"J.K.
