This thesis investigates and optimizes the palletization process at SeaJet Warehouse & Tracking, a logistics company based in New Jersey. The project originates from the need to improve space utilization on pallets and within the work area, while reducing operational waste and variability in order-preparation practices. Following a detailed As-Is analysis—conducted through direct observations, interviews, and the application of Lean tools—a computational model based on 3D bin-packing techniques was developed to determine the optimal arrangement of heterogeneous boxes. The algorithm was integrated into a Python application capable of generating multiple solutions, evaluating occupied volumes, and producing 2D/3D visual simulations. The results demonstrate a significant increase in pallet volume utilization and a reduction in operators’ decision-making time. Finally, the work provides operational recommendations and a redesigned layout for the work area, outlining the To-Be configuration of the palletization process.
Questa tesi analizza e ottimizza il processo di palletizzazione presso SeaJet Warehouse & Tracking, azienda logistica con sede nel New Jersey. Il progetto nasce dall’esigenza di migliorare l’utilizzo dello spazio sui pallet e nell’area di lavoro, riducendo sprechi operativi e variabilità nelle modalità di preparazione degli ordini. Dopo un’analisi approfondita dello stato attuale (As-Is), condotta tramite osservazioni dirette, interviste e strumenti Lean, è stato sviluppato un modello algoritmico basato su tecniche di 3D bin packing per la disposizione ottimale di pacchi eterogenei. L’algoritmo è stato integrato in un’applicazione Python in grado di generare soluzioni multiple, valutare volumi occupati ed effettuare simulazioni grafiche 2D/3D. I risultati mostrano un incremento significativo dell’utilizzo del volume utile del pallet e una riduzione dei tempi di decisione degli operatori. Il lavoro fornisce infine raccomandazioni operative e un layout ottimizzato dell’area di lavoro, delineando il modello futuro (To-Be) del processo.

Abstract
This thesis investigates and optimizes the palletization process at SeaJet Warehouse & Tracking, a logistics company based in New Jersey. The project originates from the need to improve space utilization on pallets and within the work area, while reducing operational waste and variability in order-preparation practices. Following a detailed As-Is analysis—conducted through direct observations, interviews, and the application of Lean tools—a computational model based on 3D bin-packing techniques was developed to determine the optimal arrangement of heterogeneous boxes. The algorithm was integrated into a Python application capable of generating multiple solutions, evaluating occupied volumes, and producing 2D/3D visual simulations. The results demonstrate a significant increase in pallet volume utilization and a reduction in operators’ decision-making time. Finally, the work provides operational recommendations and a redesigned layout for the work area, outlining the To-Be configuration of the palletization process.| File | Dimensione | Formato | |
