This paper has the aim to evaluate and improve the benefits of re-allocation and reshaping of zones belonging to the manual-crane area in the warehouse of Hilti Company located in Italy. The analysis is focused on the warehouse that works as a distribution center located in Carpiano. The main objectives of the Warehouse management and the Warehouse Team are to avoid waste of space and inefficiencies in the products’ picking operations and eliminate the errors in the storage process with the final aim of increasing the number of daily orders processed. Inside the manual-crane area, is applied a class-based storage allocation policy that operates in a non-stable environment: the demand of some products presents peaks and very significant fluctuations. Therefore, the inefficiencies are caused by a combination of internal factors, as methodologies used, and external ones, as non-flat demands. In the area in which the analysis is focused, are managed 46.000 different products stored into 12 shelves, 7 corridors with seven machines. Indeed, the process is articulated in the assembly of the customers’ orders, which is constituted by products stored in different areas of the warehouse, the control of the order assembly and finally the automated packaging of the orders. Past analyses revealed how the storage and picking processes in the manualcrane area were critical operations, creating a bottleneck for the order’ assembling process. Analyses performed during our thesis are supported by SAAP, that includes a simulation environment in which is possible to test the results. Simulation software could reduce risks through testing the changes applied to a process before implementing them in the real environment. The program can show results of “What if” scenarios that allow to make an evaluation on the proposed process changes. As result, it is shown how performances of the new organized warehouse will change, as well as the benefits the company will reach due to the investments and due to our proposals developed during the thesis
Questo documento ha lo scopo di valutare e migliorare i benefici della riassegnazione e della riformulazione delle zone appartenenti all'area Traslo-Manuale nel magazzino di Hilti Company, situato in Italia. L'analisi è focalizzata sul magazzino e centro di distribuzione che sono localizzati a Carpiano. Gli obiettivi principali della gestione del magazzino e del team di magazzino sono: evitare lo spreco di spazio e le inefficienze nelle operazioni di prelievo dei prodotti ed eliminare gli errori nel processo di stoccaggio con l'obiettivo finale di aumentare gli ordini giornalieri elaborati. All'interno del Traslo-Manual, nell'area viene adoperata una politica di allocazione dello stock basata su classi di prodotti che operano in un ambiente non stabile: la domanda di alcuni oggetti presenta picchi e fluttuazioni molto significative. Pertanto, le inefficienze sono causate da una combinazione di fattori interni, quali metodologie utilizzate e di fattori esterni come una domanda di mercato non stabile. Nell'area in cui si concentra l'analisi, sono gestiti più o meno 46.000 prodotti diversi immagazzinati in 12 scaffali, 7 corridoi con 7 macchine. In dettaglio, il processo è articolato nell'assemblaggio degli ordini, i quali sono costituiti da prodotti immagazzinati in diverse aree del magazzino, dal controllo dell'assemblaggio ordini e infine dall'imballaggio automatico degli stessi. Le analisi passate hanno rivelato come lo stoccaggio e il processo di prelievo nell'area Traslo-manuale rappresentavano un collo di bottiglia per il processo di creazione dell'ordine. Le ipotesi perseguite durante la nostra tesi sono supportate dal software SAAP che include un ambiente di simulazione in cui è possibile testare i risultati. Il software di simulazione potrebbe ridurre il rischio testando le modifiche dei processi prima di implementarli. Il programma può anche mostrare i risultati di possibili scenari per valutare le modifiche al processo proposte. Come risultato finale, viene mostrato come cambieranno le prestazioni del "nuovo magazzino organizzato" e i benefici che l’azienda raggiungerà grazie agli investimenti e alle nostre proposte, sviluppate durante la tesi

Abstract
This paper has the aim to evaluate and improve the benefits of re-allocation and reshaping of zones belonging to the manual-crane area in the warehouse of Hilti Company located in Italy. The analysis is focused on the warehouse that works as a distribution center located in Carpiano. The main objectives of the Warehouse management and the Warehouse Team are to avoid waste of space and inefficiencies in the products’ picking operations and eliminate the errors in the storage process with the final aim of increasing the number of daily orders processed. Inside the manual-crane area, is applied a class-based storage allocation policy that operates in a non-stable environment: the demand of some products presents peaks and very significant fluctuations. Therefore, the inefficiencies are caused by a combination of internal factors, as methodologies used, and external ones, as non-flat demands. In the area in which the analysis is focused, are managed 46.000 different products stored into 12 shelves, 7 corridors with seven machines. Indeed, the process is articulated in the assembly of the customers’ orders, which is constituted by products stored in different areas of the warehouse, the control of the order assembly and finally the automated packaging of the orders. Past analyses revealed how the storage and picking processes in the manualcrane area were critical operations, creating a bottleneck for the order’ assembling process. Analyses performed during our thesis are supported by SAAP, that includes a simulation environment in which is possible to test the results.
