Against the background of a globally increasing resource consumption, the Adaptive Remanufacturing approach in ReLIFE aims at increased resource efficiency by extending the life cycle of capital goods. Therefore, the usage of maintenance measures is optimized in technical, economic and ecological terms. The measures are controlled based on evaluations of sensor applications with the aim of maintaining a defined productivity level of the machine.
Resource-efficient life cycle extension
The research project ReLIFE aims at increasing resource efficiency by extending the life cycle of capital goods. Therefore, the innovative approach of Adaptive Remanufacturing is developed. It describes an adaptive maintenance strategy which determines the optimal time and scope of maintenance measures based on sensor technology evaluations under technical, economic and ecological aspects. In the course of ReLIFE, a prototype application is developed on an existinginvestment good. Furthermore, business models based on Adaptive Remanufacturing are developed enabling companies to generate competitive advantages. Thus, the prerequisites for the successful implementation of the approach in industry are created.
Innovation of adaptive remanufacturing
The innovative character of Adaptive Remanufacturing lies in the adaptability of the process in terms of time and content. Based on the sensor-monitored wear condition of components, preventive remanufacturing measures are proposed situation-specifically. The performance assurance of capital goods forms the basis for innovative business models to ensure long-term productivity. For example, wear parts such as filters or bearings can be monitored by sensors and maintained if necessary to maintain the agreed minimum performance level.
The research project is carried out within seven work packages. Remanufacturing approaches are developed on the basis of methodological and theoretical principles. In parallel, product design guidelines with a focus on integrated digital sensor technologies are developed and implemented within a physical demonstrator. Based on these guidelines, an evaluation model is designed and implemented in a software application to support decision-making regarding the optimized use of maintenance and remanufacturing measures. Simultaneously, remanufacturing-based business models are developed. The results obtained will be validated by means of the demonstrator.
Consortium from research and industry
The developed maintenance and remanufacturing measures are scaled and consolidated in a catalogue. For the prototypical application of Adaptive Remanufacturing, a production machine is upgraded to a demonstrator by implementing digitally networked sensor technology. The decision model to be developed is implemented in a software application. The combination of physical demonstrator and a software application enables the validation of the concept of Adaptive Remanufacturing. The affiliated business models are simultaneously developed and documented within a business model canvas.
The results will be jointly developed by the consortium partners. The Laboratory for Machine Tools and Production Engineering (WZL) of the RWTH Aachen University is the consortium leader and mainly responsible for the development of remanufacturing measures and the decision model for the application of these measures. The Chair of International Production Engineering and Management (IPEM) of the University of Siegen focuses on the development of remanufacturing-based business models. Achenbach Buschhütten GmbH & Co. KG is significantly involved in the construction of the demonstrator with integrated sensor technology.
The results of the project can be utilized within research as well as by national, international and in particular small and medium-sized companies in order to raise economic potentials through the proactive life cycle optimization of capital goods.
