Digital Process Twins for Interleaving Requirements Elicitation and Design of Cyber-Physical Systems

Cyber-Physical Systems (CPS) are increasingly becoming part of organizations' digitalization efforts in many different domains. CPS are characterized by their heterogeneity and complexity, thus requiring the involvement of various experts throughout development. Digital Twins (DTs) were found to facilitate the acquisition of such technical knowledge required for effective designs. In particular, we pose that process-oriented model representations can help to account for various concerns (e.g.: privacy and security) across CPS components in a human-centered way, thereby enabling the active participation of relevant actors in requirements elicitation and design exploration. Our human-centered approach uses Digital Process Twins (DPTs) for eliciting and refining requirements for CPS design, and for supporting agile CPS development. Our ongoing project follows the design science method. We demonstrate results of the first design cycle and provide an example illustrating the modeling part of our methodology.
