| Abstract: | This paper presents a brief, critical review and a comparative study of some design aspects of automated storage/retrieval systems with special emphasis on travel time models. These aspects include improving throughput rate, changing retrieval sequencing rules, using order batching algorithms, applying various dwell point strategies and increasing the storage/retrieval machine capacity. Some of the results and discussions used in this paper have been adopted from available sources and the rest have been compiled and/or calculated from the recent literature as mentioned therein. A conclusion is made on the salient issues prevailing in the design of automated storage/retrieval systems. |
