A digital twin, by definition, requires a physical duo for data acquisition and context-based interaction. The virtual system model in the digital duo can change in real-time as the state of the physical system changes (during operation). Today, a digital duo consists of connected products, typically using the IoT, and a digital thread. The digital thread provides connectivity throughout the life cycle of the system and collects data from the physical twin to update the models in the digital twin. Figure 1 shows the concept of digital duplication in the context of model-based systems engineering (MBSE) (Madni et al., 2019).

Looking even further, MES-PLM-ERP integration is crucial to the notion of a digital enterprise, where the real-world environment—from concept design to physical production of a product through customer usage in the field—is connected and simulated in a virtual world. By weaving a digital thread throughout all phases of a product’s lifecycle and by connecting core systems, manufacturers can gain insights to help optimize the product and key processes to achieve higher levels of productivity.

At the onset, the most fundamental question and goal of this work was to understand the capabilities and limitations of implementing a standards-based information integration throughout the lifecycle of a product. From design, through production, and final inspections, what are the hurdles that a manufacturer would face during the development of a fully linked and integrated information chain? How can these obstacles be overcome or mitigated? What benefits or incentives can be gained from tracing or linking information through multiple stages of a product lifecycle – thus, creating a “digital thread” across the lifecycle? A digital thread is an integrated information flow that connects all the phases of the product lifecycle using accepted authoritative data sources (Kraft, 2016; Hedberg Jr et al., 2016; Wardhani and Xu, 2016). The digital thread focuses on integrating all phases of the product lifecycle for making efficient and effective measurements of the lifecycle in support of data-driven methods (Hedberg Jr, Bajaj, and Camelio, 2020).

During product design, an AM digital thread makes it possible to integrate data from the design (usually using CAD software), product requirements, material information, and simulations (structural analysis, assembly analysis, etc.). New smart design phases are also achievable because of iterative developments with prototypes equipped with embedded sensors and/or the collection of end-user data. One example is the development of the Pure Strike tennis racket by Babolat. The development and design of the racket were done with end-user collaboration, and the adoption by and satisfaction of users increased in comparison with previous products of the brand.
MSDD 10.0: a design pattern for sustainable manufacturing systems

This section describes three insights gained from this research and a requirements derivation example regarding the digital thread. The digital thread with regard to this work provides a lifecycle view regarding the design, development, operation, and disposal of a manufacturing system, and its constituent processes, elements, and information. The digital thread enables the inter-connection of entities and classes of information that were previously isolated.
