Abstract

Selection of items to fill customer orders from systems of pallet rack or shelving arranged in rows with access by means of narrow aisles is becoming commonplace in many distribution centers.Such systems offer significant advantages in terms of space savings and utilization of the “cube” in distribution facilities. Narrow-aisle high-density order selection systems may tend, however, to have an adverse effect on selection productivity if not planned properly.This paper is a case study in the use of simulation as a tool for making informed decisions about the design of a narrow-aisle order selection system. Using hypothetical data, and a set of models developed in the SIMAN simulation language for one of the world's largest parts distribution centers, it examines the effect on selection productivity of three key factors in the design of a selection system:System ConfigurationStocking policySelection policy
