John is a Co-Chair of the Through-life Engineering Services Council, Member of the Team Defence Information - Digital Twin Working Group, Council Member of the Digital Twin Hub, Chartered Engineer with IET, Fellow of the Higher Education Association, Associate Member of CIRP, Former Chair of the CIRP Research Affiliates and a Member of IET. He is also the Programme Director for the MSc in Digital and Technology Solutions. This presentation will provide an overview of digital twin applications across the manufacturing sector. The talk will be structured to cover the following topics. Firstly, an overview of the most prominent areas of interest for digital twins in manufacturing will be presented. The will cut across opportunities across design teams, manufacturing processes, and maintenance interventions. This will be followed with how to design and build digital twins considering alternative challenges around data, models, and interoperability. As part of this, the emerging methods and solutions will be discussed with some insights on future directions. The presentation will close with a reflection on the potential benefits from digital twins across manufacturing.
