This thesis explores the strategic role of buffer inventory positioning in the current economic environment, characterized by high levels of uncertainty. The first part adopts a theoretical perspective, explaining the rationale behind Demand Driven Resource Planning (DDMRP), a supply chain method focused on flexibility and efficiency. Subsequently, a review of the current literature on DDMRP and buffer positioning follows. The second part focuses on the analysis of the Material Requirements Analyzer software, developed by the start-up Qantica in collaboration with the Venice School of Management at Ca’ Foscari University. A series of simulations is conducted to perform a what-if analysis, assessing the program’s performance and providing managerial insights. The evaluation emphasizes the role of inventory cost components and the trade-off between customer satisfaction and cost efficiency. Simulation results show that the software serves as a valuable decision-support tool, enabling planners to assess inventory strategies ex ante. This work offers a practical perspective on the use of buffers to improve firms’ responsiveness and operational efficiency. The adoption of software tools such as the Material Requirements Analyzer supports decision-making, leading to better outcomes in terms of service levels, resource allocation efficiency and resilience.
La presente tesi esplora il ruolo strategico del posizionamento di buffer di magazzino nell’attuale contesto economico, caratterizzato da elevati livelli di incertezza. La prima parte adotta una prospettiva teorica, illustrando la logica del Demand Driven Resource Planning (DDMRP), un metodo di gestione della supply chain orientato alla flessibilità e all’efficienza. Successivamente, una revisione della letteratura esplora quella più recente in materia di DDMRP e di posizionamento di buffer. La seconda parte è dedicata all’analisi del software Material Requirements Analyzer, sviluppato dalla start-up Qantica in collaborazione con la Venice School of Management dell’Università Ca’ Foscari di Venezia. Attraverso una serie di simulazioni, viene condotta un’analisi di tipo what-if, per valutare le prestazioni del programma e sviluppare considerazioni manageriali. L’analisi pone particolare attenzione all’impatto dei costi di magazzino e al trade-off tra soddisfazione del cliente ed efficienza dei costi. I risultati mostrano come il software rappresenti un valido strumento di supporto alle decisioni, permettendo ai pianificatori di valutare ex ante le strategie di magazzino. Il presente lavoro propone una prospettiva pratica nell'utilizzo dei buffer per migliorare la reattività e l’efficienza operativa delle imprese. L’adozione di strumenti come il Material Requirements Analyzer rappresenta un valido supporto alle decisioni, contribuendo ad ottenere migliori risultati in termini di livello di servizio, efficienza nell’allocazione delle risorse e resilienza.

Abstract
This thesis explores the strategic role of buffer inventory positioning in the current economic environment, characterized by high levels of uncertainty. The first part adopts a theoretical perspective, explaining the rationale behind Demand Driven Resource Planning (DDMRP), a supply chain method focused on flexibility and efficiency. Subsequently, a review of the current literature on DDMRP and buffer positioning follows. The second part focuses on the analysis of the Material Requirements Analyzer software, developed by the start-up Qantica in collaboration with the Venice School of Management at Ca’ Foscari University. A series of simulations is conducted to perform a what-if analysis, assessing the program’s performance and providing managerial insights. The evaluation emphasizes the role of inventory cost components and the trade-off between customer satisfaction and cost efficiency. Simulation results show that the software serves as a valuable decision-support tool, enabling planners to assess inventory strategies ex ante. This work offers a practical perspective on the use of buffers to improve firms’ responsiveness and operational efficiency. The adoption of software tools such as the Material Requirements Analyzer supports decision-making, leading to better outcomes in terms of service levels, resource allocation efficiency and resilience.File | Dimensione | Formato | |
