Abstract
Complex product family design and optimization have been playing a critical role in today's mass personalization era to allow design changeability and upgrade in an adaptable manner. Nevertheless, existing studies have no context-aware testbed to aid stakeholders' design and optimization throughout engineering product life cycle. To overcome this challenge, digital twin (DT), as an emerging concept empowered by the cutting-edge information and communication technology, has been widely adopted to realize context-aware systems across many sectors. Motivated by its advantages of high-fidelity simulation and cyber-physical interconnectivity, a generic digital twin-enhanced approach is proposed in this chapter to support the in-context virtual prototyping and reconfiguration/redesign of the complex product family with life cycle considerations. The DT environment can facilitate the modular/scalable design of the physical products in the early design stage. Meanwhile, the product-level DT established can largely support the optimization of existing product family in the usage phase. To validate its feasibility and effectiveness, a case study featuring the design and optimization solutions of a tower crane family is presented, reinforcing DT's promising role to realize Smart PSS.
