This thesis describes the project carried out within the Manufacturing Dryers team at Ceccato Aria Compressa, a leading company in the compressed air and air treatment systems sector, part of the multinational Atlas Copco Group. The aim of the project was to develop a standard model to support and rationalize decision-making processes related to the relocation of a product from one assembly line to another. To achieve this goal, the theoretical framework was first explored, with particular focus on the Analytic Hierarchy Process (AHP) decision-making method and the criteria typically used for evaluating alternatives in the industrial context considered. Subsequently, a decision-making procedure based on the AHP method was developed and adapted to the specific industrial setting. This model required the definition and detailed analysis of several decision criteria, identified in collaboration with the manufacturing engineers team: assembly time, ergonomics, costs, line efficiency, saturation, precedence and tasks, materials and equipment, space and layout. The model was then applied to a real case: the need to free up production capacity on a particularly saturated line in order to introduce a new product family. Thanks to the AHP model, it was possible to evaluate the opportunity to shift some products to alternative lines, selecting the most advantageous solution and contributing to workload balancing across the ten assembly lines in the Dryers division. In addition to providing a concrete solution to an operational issue, the work also aims to serve as a reusable decision-making tool, useful in future contexts such as the introduction of new products or the rethinking of production capacity.
La presente tesi di laurea descrive il progetto svolto presso il team Manufacturing Dryers di Ceccato Aria Compressa, azienda leader nel settore dell’aria compressa e dei sistemi di trattamento dell’aria, parte del gruppo multinazionale Atlas Copco. Il lavoro ha avuto come obiettivo lo sviluppo di un modello standard per supportare e razionalizzare i processi decisionali relativi allo spostamento di un prodotto da una linea di assemblaggio a un’altra. Per raggiungere tale obiettivo, è stato inizialmente approfondito il quadro teorico di riferimento, con particolare attenzione al metodo di analisi decisionale AHP (Analytic Hierarchy Process) e agli aspetti utilizzati per le valutazioni delle alternative nel contesto industriale considerato. Successivamente, è stata sviluppata una procedura decisionale basata sul metodo AHP, opportunamente adattata al contesto industriale. Tale modello ha richiesto la definizione e l’analisi dettagliata di diversi criteri decisionali, individuati in collaborazione con il team dei manufacturing engineers: tempi di assemblaggio, ergonomia, costi, efficienza delle linee, saturazione, precedenze e task, materiali e attrezzatura, spazio e layout. Il modello è stato infine applicato a un caso reale: la necessità di liberare capacità produttiva su una linea particolarmente satura per introdurre una nuova famiglia di prodotti. Attraverso il modello AHP, è stato possibile valutare l'opportunità di spostare alcuni prodotti su linee alternative, selezionando la soluzione più vantaggiosa e contribuendo al bilanciamento del carico tra le dieci linee di assemblaggio presenti nella divisione Dryers. Oltre a fornire una soluzione concreta a un problema operativo, il lavoro si propone come strumento decisionale riutilizzabile, utile anche in contesti futuri come l’introduzione di nuovi prodotti o il ripensamento della capacità produttiva.
