This thesis is based on a curricular internship experience at the Reggiolo (RE) headquarters of Comer Industries, within the central Manufacturing Engineering & Industrial Integration and Lean Manufacturing function. The activity was primarily oriented towards an in-depth study of the Lean logic and methodologies integrated into the World Class Manufacturing (WCM) model adopted by the Group. Subsequently, the research focused on the analysis of the new production line built in Rockford (Illinois, USA): a plant for the production of axles for CNH Industrial, with direct supply to the Fargo (North Dakota, USA) plant. The thesis has the dual objective of analyzing the WCM pillars rooted in Comer Industries' corporate culture and conducting a sensitivity analysis on the Rockford line. The analysis was conducted to test the system's logistics performance and was performed using the AnyLogic simulation software. This thesis is structured with an initial section dedicated to presenting the relevant business and industrial context. This is followed by an overview of the WCM model, which serves to further explore its technical pillars, describing their objectives, tools, and operational steps. For each pillar covered, the concrete application on the Rockford line is examined, highlighting how Lean standards and practices influenced the layout, production flows, and work organization. Finally, the aforementioned analysis of the logistics flow and the line's material procurement methods is explored in greater depth. A simulation model was built to reproduce the system's behavior to test the replenishment logic. Specifically, the simulation was used to size the optimal number of logistics carriers needed to ensure delivery continuity, minimizing the risk of potential production downtime. By varying the model's parameters, different system configurations were evaluated, analyzing the impact of the number of carriers on delivery punctuality and overall line performance. To complete the investigation, an economic evaluation was conducted to correlate logistics costs with the operational benefits obtained.
Il presente elaborato di tesi nasce dall’esperienza di tirocinio curriculare svolta presso la sede di Reggiolo (RE) di Comer Industries, all’interno della funzione centrale di Manufacturing Engineering & Industrial Integration and Lean Manufacturing. L’attività è stata orientata, in primo luogo, all’approfondimento delle logiche e delle metodologie Lean integrate nel modello World Class Manufacturing (WCM) adottato dal Gruppo. Successivamente, la ricerca si è focalizzata sull’analisi della nuova linea produttiva realizzata a Rockford (Illinois, USA): un impianto destinato alla produzione di assali per CNH Industrial, con fornitura diretta allo stabilimento di Fargo (North Dakota, USA). L’elaborato si pone il duplice obiettivo di analizzare i pilastri del WCM radicati nella cultura aziendale di Comer Industries e di condurre un’analisi di sensitività sulla linea di Rockford. L’analisi è stata condotta per testare le performance logistiche del sistema ed è stata svolta attraverso l’ausilio del software di simulazione AnyLogic. La struttura di questa tesi prevede una sezione iniziale dedicata alla presentazione del contesto aziendale e industriale di riferimento. In seguito, è riportata una panoramica sul modello WCM, funzionale a un approfondimento dei suoi pilastri tecnici, dei quali vengono descritti obiettivi, strumenti e step operativi. Per ogni pilastro trattato, si esamina l’applicazione concreta sulla linea di Rockford, evidenziando come gli standard e le pratiche Lean abbiano influenzato il layout, i flussi produttivi e l’organizzazione del lavoro. Infine, viene approfondita la sopracitata analisi del flusso logistico e delle modalità di approvvigionamento dei materiali della linea. Attraverso la costruzione di un modello di simulazione, è stato riprodotto il comportamento del sistema per testare le logiche di rifornimento. Nello specifico, la simulazione è stata utilizzata per dimensionare il numero ottimale di trasportatori logistici necessari a garantire la continuità delle consegne, minimizzando il rischio di possibili fermi produttivi. Attraverso la variazione dei parametri del modello, sono state valutate diverse configurazioni del sistema, analizzando l’impatto del numero di trasportatori sulla puntualità delle consegne e sulle prestazioni complessive della linea. A completamento dell’indagine, è stata condotta una valutazione economica per mettere in relazione i costi logistici con i benefici operativi ottenuti.
