Abstract
Challenged by an unprecedented increase in product variety and demand variability, logistics systems are required to fulfill small customer orders at competitive costs and within short lead times, while keeping a high level of flexibility. In this context, companies are increasingly adopting flexible material handling solutions based on autonomous mobile robots (AMRs). This paper deals with AMR-based Automated Pick to Pallet Systems (APPSs), a novel solution for mixed-case palletizing that has never been studied in scientific literature. In these systems, palletizing robots pick boxes from single-item source pallets and place them on mixed pallets under construction. AMRs replenish the palletizing robots with source pallets and transport the mixed pallets to and from the different palletizers until completion. An agent-based simulation model for the estimation of AMR-based APPS performance is presented and validated. The developed model can be easily modified and adapted to test different layout configurations and management policies. Therefore, it provides support to companies evaluating the introduction of such systems and lays the grounds for further research on their suitability in different contexts, also in comparison with existing systems.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
