N1  - In this paper, we study the effect of sequencing storage and retrieval requests on the performance of automated storage and retrieval systems (AS/RS) where a storage request is assigned a predetermined storage location. By exploiting this unique operating characteristic, we present several optimum and heuristic sequencing methods under static and dynamic approaches. Applications of such sequencing methods include unit-load AS/RS with dedicated storage, miniload AS/RS, and potentially unit-load AS/RS with randomized storage. We find that the sequencing methods can significantly reduce travel time by a storage and retrieval machine, thereby, increasing throughput, and that the dynamic heuristic method is simple and fast, yet considerably outperforms the others
