A Systematic Method for Increasing the Energy and Resource Efficiency in Manufacturing Companies

SME appropriate concept for continuously improving the energy and resource efficiency in manufacturing companies

“…3; more detailed information can be found in Ref. [33]. While using available data on nominal values and operating times, the idea is to derive distinctive classifications of consumers which lead to different strategies and priorities for further procedure.…”

A methodology for customized prediction of energy consumption in manufacturing industries

“…5 vs. 6 active heaters be seen, that even with the massive simplifications the right magnitude can be predicted which is notable because the effort necessary is quite small. The benefit can be seen by comparing this predicted value of 181.01 Wh to the prediction based on power ratings as proposed in [4]: The machining centre has a rated power of 20 kVA. The whole process takes 420 sec including the idle time for re-clamping.…”

“…Moreover, lack of transparency in relation to energy consumption and energy hot spots further hinders implementing improvement measures with an adequate leverage effect. 4 Energy consumption is driven by production machines, technical building equipment, as well as office areas etc. in the form of various energy carriers such as electricity, gas and diesel.…”

“…These values are generally too high since they reflect the maximum operational power. 4 He et al devised a method to estimate energy consumption of NC machining that uses the correlation between NC codes and energy consuming components. Based on specific NC tags (M, S, G, F, T), the machine components show a characteristic behavior that can be linked to their energy consumption.…”

“…This follows the idea of establishing energy portfolios proposed by Thiede et al. 4 There are generally two options to determine the relevance of a hotspot. The selection of these two options depends on the number of different products or product families being produced in the company.…”
