Chapter
Since the 1980s society has been largely satisfied with modern manufacturing’s production practice. We are able to develop supply chains that can produce today’s highly complex and advanced products and are able to scale mass production to meet much of society’s demands.
Article
Models of distributed agent-based Additive Manufacturing (AM) systems have suggested that considerable productivity, reactivity, and resiliency gains can be realised. However, there remains scepticism and real-world validation is required to demonstrate the benefits, practicalities, and challenges of implementing agent-based manufacturing systems....
Article
COVID-19 and global crises/events are driving governments to rethink their national manufacturing strategies. The drastic change of societal conditions has exposed our reliance on a constrained set of production practices. Furthermore, the future manufacturing landscape indicates - supply chain crises, trade agreements and natural disasters - a hig...
Chapter
Workshops are vital to product development, supporting prototyping, research & development, bespoke and small-batch production, and education. They are composed of diverse manufacturing capability that needs to meet varied, rapid, diverse and often random changes in demand. The diversity in both composition and demand continues to challenge the opt...

Classifying shape and form is a core feature of Engineering Design and one that we do this instinctively on a daily basis. Matching similar components to then reduce unique component counts, determining whether a competitors design infringes on copyright and receiving market feedback on product styling are all examples where shape and form comes in...
Article
Full-text available
The importance of prototyping is unanimous with numerous studies into the media, types, roles and properties of prototypes. However, no recent papers have sought to examine and characterise industry practice and if and how this has changed since the early 2000s. To address this, a snapshot of industrial prototyping practice with particular attentio...

Full-text available
Combinatorial Design such as configuration design, design optioneering, component selection, and generative design, is common across engineering. Generating solutions for a combinatorial design task often involves the application of classical computing solvers that can either map or navigate design spaces. However, it has been observed that classic...
