  • Combining in-house Pooling and Sequencing for Product Regeneration by Means of Event-driven Simulation 
    Denkena, Berend; Dittrich, Marc-André; Georgiadis, Alexander (Amsterdam : Elsevier BV, 2017)
    The condition of complex products in the transport industry, such as train couplings or aircraft turbines, is not exactly determinable before their disassembly and diagnosis in a maintenance plant. Thus, planning and control ...
  • Competence-based Personnel Scheduling through Production Data 
    Denkena, Berend; Dittrich, Marc-André; Winter, Florian (Amsterdam : Elsevier BV, 2017)
    Personnel scheduling closes the missing link between personnel and production planning in manufacturing companies. Personnel scheduling has a significant impact on the development of employee competencies and the achievement ...
  • Continuous modelling of machine tool failure durations for improved production scheduling 
    Denkena, Berend; Dittrich, M.-A.; Keunecke, L.; Wilmsmeier, S. (Heidelberg : Springer, 2020)
    Unforeseen machine tool failures due to technical issues can cause downtimes leading to delays during production. To reduce delays, rescheduling of the production is, in most cases, necessary. However, warranting such a ...
  • Correlation between process load and deep rolling induced residual stress profiles 
    Denkena, Berend; Grove, Thilo; Breidenstein, Bernd; Abrão, A.; Meyer, K. (Amsterdam : Elsevier B.V., 2018)
    Deep rolling is often used as a finishing step after cutting because of its beneficial influence on surface and subsurface properties, which lead to an increase in performance and lifecycle behavior. This manufacturing ...
  • Dynamic Bid Pricing for an Optimized Resource Utilization in Small and Medium Sized Enterprises 
    Denkena, Berend; Dittrich, Marc-André; Stamm, Siebo (Amsterdam : Elsevier B.V., 2018)
    Sales revenues of small and medium-sized enterprises are subject to seasonal fluctuation. This leads often to overloaded or underutilized manufacturing resources. Either way, this results in revenue losses. Therefore, ...
  • Energy Efficiency in Machining of Aircraft Components 
    Denkena, Berend; Dittrich, Marc-André; Jacob, Stefan (Amsterdam : Elsevier, 2016)
