An analytical approach for a performance calculation of shuttle-based storage and retrieval systems with multiple-deep and class-based storage

This paper presents a method for determining the performance of shuttle-based storage and retrieval systems (SBS/RS) with tier-captive, single-aisle shuttles serving tiers multiple-deep using class-based policy. approach is used in design process SBS/RS upgrading existing SBS/RS. With this approach, it possible to evaluate improvement system by applying The basis calculation continuous-time, open-queueing limited capacity. cycle times lifts shuttles, as determined spatial value combined probability-based mention To take into account, another applied. A European material handling provider had given data publication. Through an example, influences policy depth are depicted.
