UdZ 2-2013

22 Unternehmen der Zukunft 2/2013 UdZ Informationsmanagement logy shown in Figure 2. The following phases of the project are based on the gathered require- ments to develop a Sense&React platform, which can be used in all application scenarios. The role of the FIR during the requirements analysis was primarily the requirement elicitation and accumulation in cooperation with the diffe- rent application partners, allowing for bundled requirements catalogue for the Sense&React platform to be created. Special attention was paid to the requirements regarding optimisation of energy efficiency in real time. In this particular area of the project, a de- tailed energy efficiency concept is created by FIR to support the manufacturing company beyond energy management standards and guidelines. The concept will support companies to define a specific objective function with respect to the optimisation of energy efficiency (this may vary depending on the focus on economic or technical aspects) and will describe the necessary sensor readings that must be available to determine relevant indicators regarding the objective func- tion. Based on the identification of non-energy- efficient states, the concept will further assist in the evaluation of the relevance and urgency of these deficits in energy efficiency and finding measures to optimise energy efficiency. Non-energy-efficient conditions were investigated based on the lean principles and studies on energy efficiency in production environments. A total of six types of energy wastage were found, four of which can arise during production and can thus be identified by a system operating in real-time: • Inefficient operating mode of the machine • Malfunction • Wear • Outdated Components The two other types of energy wastage are caused in strategic planning and design of pro- duction processes, namely inefficient process mo- delling and oversized components. However, this cannot be monitored by the planned IT platform. As part of the Sense&React platform, this the- oretical concept will be automated, so energy- inefficient states are identified in real time, the urgency and magnitude is determined and relevant decision makers will be informed about possible actions to address these conditions. The elaborate and detailed approach to the requirements elicitation and the development of a detailed energy efficiency concept should ultimately serve to develop this extensive and complex platform within the project as practice oriented as possible in order to assist manufactu- ring companies in addressing and mastering the challenges described here.
