After finding the root causes behind the above mentioned critical points, the main defined countermeasures are: Mizusumashi approach and workload distribution to increase the orientation toward production; warehouse redesign to increase the space efficiency; TMS and EDI implementation to streamline the inbound process and decrease congestion; KPI dashboard implementation to monitor operator procedures and inventory status. The “Zero forklifts” project is currently on-going. The feasibility study on the proposed solutions will be performed once all data will be available.
L’obiettivo aziendale è di eliminare la circolazione di carrelli elevatori dall’impianto produttivo per ridurre il rischio di incidenti. Inoltre, lo spazio disponibile non permette l’espansione del business, di conseguenza è richiesta una analisi dell’efficienza dello spazio attuale. Questa tesina ha lo scopo di supportare il progetto “Zero forklifts” con un’analisi dello stato attuale e la definizione di possibili soluzioni. L’analisi è concentrate sul dipartimento Timing Systems Components (TSC) e sul magazzino, a causa del loro alto impatto sul progetto. Prima di tutto, è stato effettuato uno studio sui volumi disponibili nel magazzino, evidenziando l’occupazione dei vani e la saturazione delle unità di carico. È stata tracciata una mappa complete dei flussi all’interno dell’impianto produttivo, analizzando approfonditamente i primi 22 che compongono il 93% dei movimenti delle handling unit. Particolare attenzione è stata data ai flussi riguardanti il TSC: l’analisi tocca le linee e le stazioni più critiche, i materiali di input e output, le scorte e le procedure. Le principali criticità sono state trovate in: il disallineamento fra i lotti in scorta e quelli necessari alla produzione (31% dei flussi in uscita dal TSC sono resi di componenti input al magazzino); le basse occupazione dei vani e saturazione delle unità di carico in magazzino (rispettivamente 41% e 47% nel caso dei prodotti finiti); l’alta variabilità delle giacenze lungo i giorni del mese (35% dell’inbound è nella prima settimana, 35% dell’outbound è nell’ultima settimana); l’alto impatto delle attività non a valore aggiunto nei flusso del TSC e nella generale congestione. Dopo aver trovato le cause principali delle criticità menzionate, sono state ideate delle contromisure: l’approccio Mizusumashi e la distribuzione del carico di lavoro per incrementare l’orientamento verso la produzione; il ridisegno del magazzino per incrementare l’efficienza dello spazio; l’implementazione di TMS e EDI per velocizzare il processo di inbound e ridurre la congestione; l’implementazione di un cruscotto di KPI per monitorare le procedure degli operatori e lo stato delle giacenze. Il progetto “Zero forklifts” è tuttora in corso. Lo studio di fattibilità sulle soluzioni proposte verrà svolto quando tutti dati saranno a disposizione.

Abstract
The company aims at eliminating the forklift circulation inside the production plant to reduce accident risk. Moreover, the available space does not permit business expansion, so a current space efficiency study is required. This paper has the scope of supporting the “Zero forklifts” project with a current situation analysis and definition of possible solutions. This analysis is mainly focused on Timing Systems Components department (TSC) and the warehouse because of their high impact on the topics of the project. First of all, a study on the available warehouse volumes was performed, showing occupation of the bays and the saturation of loading units. A complete mapping of the flows in the production plant was designed, deeply analyzing the first 22 that compose 93% of the handling units movements. Great attention was given to the flows regarding TSC: the analysis regarded the most critical lines and stations, the input and output materials, their inventory and the procedures. The main critical points were found in: the misalignment between material lots in inventory and the lots needed for production (31% of the outflows from TSC are returns of input components to warehouse); the low occupation of the bays and saturation of the loading units in warehouse (respectively 41% and 47% in case of finished product); the high variability of stock levels along the days of a month (35% of inbound in the first week, 35% of outbound in the last week); the high impact of NVAA in TSC flows and general congestion. After finding the root causes behind the above mentioned critical points, the main defined countermeasures are: Mizusumashi approach and workload distribution to increase the orientation toward production; warehouse redesign to increase the space efficiency; TMS and EDI implementation to streamline the inbound process and decrease congestion; KPI dashboard implementation to monitor operator procedures and inventory status. The “Zero forklifts” project is currently on-going. The feasibility study on the proposed solutions will be performed once all data will be available.| File | Dimensione | Formato | |
