We consider the route planning problems in large-scale automatic storage and retrieval systems (AS/RS), with a focus on the interaction of shipments. First, we propose a strategic flow model to spread out the flow of shipments over the K shortest paths in the long term. Secondly, based on the dynamic stochastic shortest path model, we develop an adaptive routing strategy with advantages in facilitating dynamic routing fashion with real-time information. Numerical experiments show that the two proposed routing strategies achieve 12.8% and 28.8% improvement on travel time respectively.
