Data-based energy performance root cause analysis methodology

The automotive industry aims to achieve continual improvement in energy performance to reduce emissions and costs. High complexity in manufacturing systems makes comprehensive analyses economically infeasible thus a root cause analysis (RCA) methodology is required to identify and quantify subsystems with a high energy saving potential. This allows targeted analyses and measures to be derived. For this purpose, a data-based benchmarking approach for identification and quantification of energy saving potential is developed. The methodology has proven to be suitable to derive significant energy savings in the validation based on a real use case of a globally operating car manufacturer.
