TL;DR: In this article, the authors proposed a new heuristic, Percentage Priority to Retrievals with Shortest Leg (PPR-SL), which is shown to consistently outperform all of the other heuristics.

TL;DR: In this paper, a traffic flow-based closed queuing network model is used to model the effect of vehicle congestion on the internal transport of containers at a terminal, and the model can also be used to determine the appropriate number of vehicles required to achieve the required terminal throughput.

TL;DR: A decision-tree heuristic is proposed to minimise the expected number of reshuffles when arriving containers should be stacked in a block of containers with an arbitrary number of piles to significantly outperform stacking policies commonly used in practice.

TL;DR: A travel time model and an algorithm that can be used for determining the optimal number and boundaries of storage classes in warehouses are developed and illustrate that commonly a small number of classes is optimal.

TL;DR: The state of the practice in OR and freight transportation is described, highlighting recent successful and widely used analytical techniques in oceanic transportation and port operations, and barge, freight rail, intermodal, truck load, less than truckload, and air freight transportation, as well as the use of OR techniques in third-party logistics.
