How to use virtual prototyping to design Product-Service Systems

Numerous companies all around the world are shifting from traditional products to product-service solutions, thanks to the increased “intelligence” and “ connectivity” of modern products and the more deep integration among mechanics, electronics, Information and Commutation Technologies (ICT) and Internet of Things (IoT). Such Product- Service Systems (PSSs) are usually designed and developed by considering product and service as separated entities with the consequent increase of design and validation difficulties. In addition, a final physical prototype has to be realized to validate the overall solution. In this context, Virtual Prototyping can support PSS design to reduce process iterations and time to market. However, actual virtual prototypes are usually conceived for product validation, and are not so effective for PSS. The paper defines a set of requirements for PSS simulation on digital models, and defines a set of tools for successful PSS prototyping.
