Energy efficiency benchmarking concepts for different automated storage and retrieval systems
The purpose of this paper is to present a new way in comparing and evaluating the energy efficiency of fully automated storage and retrieval systems. Due to the very different nature of miniload systems, horizontal carousel systems and shuttle systems, a new approach was elaborated to provide comparability.In a first step, the equivalency of the three systems was to be established. This was achieved by using the storage capacity as base parameter. In case that the real rack systems are not equal, virtual rack dimensions are calculated. Further, a representative operating cycle was defined, which includes three different operating states. Another step in providing comparability is to define specific reference points. These storage compartments were chosen in accordance with standard guidelines. The specific energy demand can be measured and energy efficiency indicators can be calculated.
