摘要：In this paper, we do research on a new compact storage system which is an extension of conventional automated storage and retrieval system (AS/RS). The new system consists of the S/R machine which travels simultaneously in the horizontal and vertical dimension. At the same time, there is a conveyor system which is in charge of motion of depth dimension which means there are several storage cells near the aisle. With consideration of operating characteristic, a new travel time model is formulated for the single command cycle. In order to analyze performance and optimal rack dimension, we present the minimum expected travel time and optimal rack dimension. In the end, we verify the travel time model and optimal rack dimension design by a practical example. © 2014 SERSC.
