Once implemented, CPS will increase the efficiency of operations, improve product quality, reduce waste, and optimize the use of resources and assets. A critical element for the realization of CPSs is the Digital Twin (DT), a concept that bridges the gap between the physical and digital realms. Although significant strides have been made to establish the nature of DT, there is still a need for comprehensive reference models and test cases that can help guide the design and deployment of DT. This work presents a reference model for the development of DT. The model considers factors such as stage in the life cycle of a product, the purpose of the digital representation, and the use of the information that the digital representation provides. Cases are presented and analyzed in terms of the proposed model.
