Abstract: A cycle-time model for class-based storage policies is proposed for automated unit load Storage and Retrieval (S/R) systems that use autonomous vehicle technology. The model is based on a queuing network approach to achieve sufficient accuracy and computational efficiency for system design conceptualisation applications. It is illustrated through a series of realistic case problems.

Keywords: unit load storage and retrieval; autonomous vehicles; class-based storage; queuing networks; performance modelling; automated guided vehicles; AGVs; AS/RS.
