L’avvento delle nuove linee guida dettate dall’implementazione della Circular Economy e il recente cambiamento del trend di mercato manifatturiero verso una produzione orientata al cliente hanno evidenziato notevoli criticità sotto il punto di vista della flessibilità dei sistemi di produzione. Queste problematiche sono ancora più evidenti considerando le fasi di de e re-manufacturing, poiché la variabilità delle condizioni dei prodotti è determinata dalla variazione dei prodotti realizzati in fase di manufacturing, a cui si aggiunge una componente non prevedibile e specifica per ciascun prodotto in fase di rientro dovuto al consumo e alla dispersione delle caratteristiche nominali durante il ciclo di vita operativo. Questo, in caso di sistemi di produzione rigidi, comporterebbe problemi in fase di production planning e notevoli inefficienze durante le fasi di de e remanufacturing. Al fine di contrastare le limitazioni attuali dei metodi di Short Term Production Planning, questo lavoro di tesi propone un sistema Knowledge-Based per la generazione di planning di attività, con l’obiettivo di garantire la flessibilità necessaria per rispondere alle esigenze di mercato nel contesto del de e remanufacturing. La soluzione proposta garantisce un’applicabilità estensibile e modulabile attraverso l’utilizzo di un Knowledge Shell. Successivamente, verrà trattato un caso studio applicato alle attività di de e remanufacturing per motori elettrici al fine di testare e validare il metodo proposto.

Abstract
The advent of the new guidelines dictated by the implementation of the Circular Economy and the recent shift in the manufacturing market trend toward customer-oriented production have highlighted significant critical issues from the standpoint of flexibility in manufacturing systems. These issues are even more pronounced considering the de and remanufacturing phases, as the variability of product conditions is driven by the variation of products made in the manufacturing phase, to which is added an unpredictable and product-specific component in the remanufacturing phase due to consumption and dispersion of nominal characteristics during the operational life cycle. This, in the case of rigid manufacturing systems, would lead to problems during production planning and significant inefficiencies during de and remanufacturing. In order to counter the current limitations of Short Term Production Planning methods, this thesis proposes a Knowledge-Based system for generating activity schedules to provide the flexibility to meet market needs in the context of de and remanufacturing. The proposed solution ensures extensible and scalable applicability through a Knowledge Shell. Next, a case study will be conducted to de and remanufacturing activities for electric motors to test and validate the proposed method.File | Dimensione | Formato | |
