Mobile assistance for energy-efficient production
Scenario parameters and system impact
Increasing scarcity of resources and high energy costs have led to an increasing relevance of energy-efficiency over the last few years. While a lot of efforts are already being made to optimize energy-efficient production in large companies, there is still a lack of practicable support for small and medium enterprises (SMEs). The supply of mechanical energy accounts for 64% of the overall industrial energy consumption in Germany. While new equipment is mostly designed according to energy-efficiency requirements, feasible action is needed to decrease energy consumption of existing equipment on the shop-floor level. As actions on this small scale rely on dependable information and its use at the right time and place, involvement of ICT devices becomes evident. To contribute to the overall goal of energy efficiency, this paper describes scenarios as well as a derived system design to integrate mobile and stationary devices for energy-efficient dimensioning and energy-optimized operation within the framework of order-related manufacturing. The approach is based on role definitions of stakeholders, who may influence energy-efficiency measures in a manufacturing context. Scenarios are used to identify promising energy-efficiency measures. The scenarios include parametric estimates for production plans, order sequences and workload. Emphasis is placed on the consolidated consideration of various individual measures. The scenarios provide a basis for further requirements analysis and evaluation of the assistant system.
