Buffer_Reshuffling_and_Retrieval_Integer_Programming_Instances_and_Results

However, current labor shortages highlight the urgent need to automate these tasks. This paper addresses the Buffer Reshuffling and Retrieval (BRR) problem, which aims to optimize the reshuffling and retrieval of unit loads within a buffer zone.

The buffer zone is assumed to be a designated area on the floor where items are stored without the use of shelves or other intermediary structures. We extend the static BRR model, which assumes a fixed set of items, to address the complexities of modern, dynamic production logistics. Specifically, we introduce two extensions: (1) a dynamic variant that accounts for new items requiring storage in the buffer, and (2) a dynamic multi-AMR variant that utilizes multiple Autonomous Mobile Robots (AMRs).
