Lean Production is recognized as an organizational method based on the principle of continuous improvement. Specifically, it provides a set of principles and methods that are aimed at eliminating waste and bringing business processes to excellence. This thesis presents the case study carried out at DAB Pumps, a company specialized in water treatment and management technologies. The main objective of the project was the reduction of raw material and semi-finished product warehouse space and its related value. This thesis shows how through the application of lean philosophy, the company has been able to achieve greater performance. After an initial analysis phase, flow mapping was done which showed that the most significant source of waste was the lack of synchronization of lines along the value creation process. The line producing semi-finished products was acting as an independent department aimed at achieving maximum efficiency, without considering the real need to produce or not. The thesis shows how through the application of the kanban it was possible to synchronize the two production lines, reasoning from a "pull" rather than a "push" perspective. Taking into account all the constraints currently present and the subject of the subsequent improvement projects, kanban sizing was done in order to ensure the continuous feeding of the downstream line and, at the same time, to control the production of the upstream line, avoiding the creation of an excessive stock of semi-finished products. Comparing the performance achieved in 2021 before the project with the performance in 2022, year in which it was implemented, it is highlighted how through the application of lean principles and tools, companies can gradually improve their performance.
La Lean Production è riconosciuta come un metodo organizzativo che si basa sul principio del miglioramento continuo. In particolare, fornisce un insieme di principi e metodi che mirano a eliminare gli sprechi e a portare i processi aziendali all'eccellenza. In questa tesi viene presentato il caso studio effettuato presso l’azienda DAB Pumps, un'azienda specializzata nel settore delle tecnologie per il trattamento e la gestione dell’acqua. L'obiettivo principale del progetto era la riduzione dello spazio di magazzino materie prime e semilavorati ed il relativo valore. Questa tesi mostra come attraverso l’applicazione della filosofia lean, l’azienda è riuscita ad ottenere maggiori performance. Dopo una prima fase di analisi, è stata fatta una mappatura del flusso attraverso la quale è subito emerso che la maggiore fonte di spreco era la mancata sincronizzazione delle linee lungo il processo di creazione del valore. La linea che produce semilavorati ragionava come reparto indipendente volto a raggiungere la massima efficienza, senza considerare la reale necessità di produrre o meno. Nell’elaborato viene mostrato come attraverso l’applicazione del kanban si sia riusciti a sincronizzare le due linee di produzione, ragionando con un’ottica “pull” anziché “push”. Tenendo conto di tutti i vincoli attualmente presenti e oggetto dei successivi progetti di miglioramento, è stato fatto un dimensionamento del kanban in modo da garantire il continuo asservimento della linea a valle e, allo stesso tempo, controllare la produzione della linea a monte, evitando di creare un eccessivo magazzino di semilavorati. Confrontando le performance ottenute nel 2021 prima del progetto con quelle del 2022 anno nel quale è stato implementato, viene messo in evidenza come attraverso l’applicazione dei principi e strumenti lean, le aziende possano migliorare gradualmente le proprie performance.

Abstract
Lean Production is recognized as an organizational method based on the principle of continuous improvement. Specifically, it provides a set of principles and methods that are aimed at eliminating waste and bringing business processes to excellence. This thesis presents the case study carried out at DAB Pumps, a company specialized in water treatment and management technologies. The main objective of the project was the reduction of raw material and semi-finished product warehouse space and its related value. This thesis shows how through the application of lean philosophy, the company has been able to achieve greater performance. After an initial analysis phase, flow mapping was done which showed that the most significant source of waste was the lack of synchronization of lines along the value creation process. The line producing semi-finished products was acting as an independent department aimed at achieving maximum efficiency, without considering the real need to produce or not. The thesis shows how through the application of the kanban it was possible to synchronize the two production lines, reasoning from a "pull" rather than a "push" perspective. Taking into account all the constraints currently present and the subject of the subsequent improvement projects, kanban sizing was done in order to ensure the continuous feeding of the downstream line and, at the same time, to control the production of the upstream line, avoiding the creation of an excessive stock of semi-finished products. Comparing the performance achieved in 2021 before the project with the performance in 2022, year in which it was implemented, it is highlighted how through the application of lean principles and tools, companies can gradually improve their performance.File | Dimensione | Formato | |
