Calculation method to determine the throughput and the energy consumption of S/R shuttle systems

Abstract

Shuttle systems are used in high performance automated storage/retrieval unit load systems. Each storage level is serviced by one shuttle. On the front side of the rack there is a lift for storage and retrieval. A different number of buffer slots can be located between the lifts and the respective levels. These systems are already treated in various scientific papers. In this paper, the calculation of the throughput of a shuttle system and, more particularly, the calculation of the energy consumption for the handling of a tote in such a system is presented. The results of these calculation methods are shown.
