The paper deals with the design of storage systems. The focus is on storage racks that are accessed in a Last-In-Fist-Out manner (e.g. 'drive-in' racks). Such a type of rack storage is more space-efficient than, e.g., single deep selective racks (less aisle space is required per pallet location); on the other hand, pallets are not independently accessible and replenishing/emptying cycles are required. This leads to a reduction of a performance measure called here storage efficiency. The aim of the study is to present a methodology for computing the storage efficiency with respect to different production/delivery patterns of the allocated items. Then, the overall system performance can be assessed by investigating the trade-off between storage efficiency and space utilization. Moreover, the benefit of integrating LIFO storage with automated guided vehicles (AGVs) is discussed. The methodology is finally applied to a case study.

Abstract
The paper deals with the design of storage systems. The focus is on storage racks that are accessed in a Last-In-Fist-Out manner (e.g. 'drive-in' racks). Such a type of rack storage is more space-efficient than, e.g., single deep selective racks (less aisle space is required per pallet location); on the other hand, pallets are not independently accessible and replenishing/emptying cycles are required. This leads to a reduction of a performance measure called here storage efficiency. The aim of the study is to present a methodology for computing the storage efficiency with respect to different production/delivery patterns of the allocated items. Then, the overall system performance can be assessed by investigating the trade-off between storage efficiency and space utilization. Moreover, the benefit of integrating LIFO storage with automated guided vehicles (AGVs) is discussed. The methodology is finally applied to a case study.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
