Il magazzino è un componente fondamentale in una supply chain competitiva. Nonostante la crescente necessità di ridurre i tempi delle principali attività nei magazzini, la letteratura non fornisce una metodologia concreta per identificare e ridurre perdite di tempo nelle attività relative al magazzino. Pertanto, l'obiettivo di questa tesi è fornire un approccio, basato su pratiche appartenenti alla lean management, per aumentare le prestazioni delle operazioni di magazzino. L'approccio proposto integra diverse pratiche del lean management come Value Stream Map, Gemba walk, Ishikawa diagram e analisi di Pareto seguendo l’A3 problem solving. La metodologia proposta è stata validata attraverso un caso studio riguardante il magazzino dell’azienda di distribuzione di componenti microelettronici Sge-Syscom. Tale analisi ha fornito vantaggi qualitativi e quantitativi per l'azienda. I principali risultati della ricerca hanno evidenziato una riduzione del 50% del tempo impiegato durante le attività di prelievo e stoccaggio svolte nel magazzino, migliorando così le prestazioni di esso. Inoltre, lo studio contribuisce a organizzare le SKUs in modo strutturato consentendo opportunità di crescita per l'azienda. Pertanto, lo studio effettuato contribuisce ad aumentare la conoscenza e la ricerca sulla riduzione dei tempi nei magazzini di distribuzione, eseguendo una metodologia lean per aiutare le aziende a raggiungere prestazioni più elevate riducendo le attività non a valore aggiunto. Infine, l'approccio proposto potrebbe essere implementato in contesti simili per aumentare la robustezza della metodologia e dei risultati ottenuti in un singolo caso di studio.

Abstract
A distribution warehouse is a fundamental component of a competitive supply chain. For warehouses, the literature doesn’t provide a concrete methodology for identifying and decreasing waste in warehouse operations. Therefore, this thesis aims to provide an approach, based on lean management practices, for increasing warehouse operations’ performances. The proposed approach integrates different lean practices such as Value stream map, Gemba walk, Ishikawa Diagram and Pareto analysis following the A3 problem-solving technique. The proposed methodology was validated via a case study in the SGE-Syscom distribution warehouse providing qualitative and quantitative benefits for the company. The main findings of the research showed a 50% reduction in time spent during picking and storing activities performed in the warehouse thus improving warehouse performance. Furthermore, the study contributes to organizing SKUs in a structured way allowing growth opportunities for the company. As a result, the study contributes into increasing knowledge and research on reducing operational waste in distribution warehouse by executing a lean methodology for helping companies reach higher performances by reducing non-value-added activities. Finally, the proposed approach could be implemented in similar contexts to increase the robustness of the methodology and results achieved in a single case study.| File | Dimensione | Formato | |
