| Sumario: | This thesis explores Metrology as a Service (MEaaS) as a way to increase flexibility and resilience in the semiconductor industry through shared resources and standardized data exchange. The objective is twofold: first, to propose an implementation pathway for MEaaS using digital twins in the Asset Administration Shell (AAS) format and secure data sharing via the Eclipse Dataspace Connector (EDC); and second, to quantify the potential benefits of MEaaS through a discrete-event simulation. The methods combine business process modelling, the creation of AAS-based digital twins (with a focus on the Wafer AAS), and a simulation built in AnyLogic using real Infineon data. The model reproduces demand patterns, capacity constraints, and lead times to evaluate disruptions and the possible role of MEaaS. Results show that demand-driven disruptions are the most critical, while capacity disruptions have more localized effects. By rerouting late lots and monetizing idle capacity, MEaaS could generate economic benefits of about €497 million per year for Infineon. The conclusions are that MEaaS is technically feasible, economically relevant, and a promising step toward more resilient and sustainable semiconductor supply chains. |
