Simulation-based Assessment and Optimization of the Energy Consumption in Multi Variant Production

Two influences are decisive in today's industrial production: a significant increase of variants and an upwards trend of energy costs. Therefore it is necessary to clarify, if and in which dimensions the energy consumption is influenced by variety and how it can be handled. For this reason a si...

Description
Summary:Two influences are decisive in today's industrial production: a significant increase of variants and an upwards trend of energy costs. Therefore it is necessary to clarify, if and in which dimensions the energy consumption is influenced by variety and how it can be handled. For this reason a simulation-based model is developed, which allows the examination of the effects of variety on energy consumption (electricity, compressed air, gas). The benefits of this model are that interdependencies within the production can be considered and that it is possible to quantify the potential for improvement. Starting points to increase the energy efficiency can be identified. The model was implemented in a discrete event simulation environment and verified in a case study in the metalworking industry. The results show, that an efficient variant management allows a significant improvement of the energy efficiency without compromising in matters of produced variants.
