In today’s competitive scenario of increasingly faster deliveries and smaller order sizes, material-handling\udproviders are progressively developing new solutions. A recent, automated material-handling technology for\udunit load storage and retrieval consists of an autonomous vehicle storage and retrieval system (AVS/RS). The\udpresent paper presents an analytical model to estimate the performances (the transaction cycle time and\udwaiting times) of AVS/RS for product tote movement. The model is based on an open queuing network\udapproach. The model effectiveness in performance estimation is validated through simulation.
