Dynamic Warehouse Environments for Crane Stacking and Scheduling

Dynamic optimization is of high practical relevance for many production and logistics processes. Often however, in research, the dynamics are neglected and an algorithm or optimization is presented for a static decision scenario. The effects that occur with implementing decisions one by one in a dynamic environment subject to other dynamic events have not received as much attention as static problem scenarios. We think this is in part due to the increased complexity of describing a dynamic environment and parameterizing it in a meaningful way. In this publication we present three dynamic environments in the context of warehouse logistics where manipulation occurs by gantry cranes. Our scenarios are heavily inspired by real-world steel logistics operations. We provide free open source implementations of these dynamic environments. (C) 2022 The Authors. Published by Elsevier B.V.
