A Method for Deriving Technical Requirements of Digital Twins as Industrial Product-Service System Enablers

Industrial Product-Service Systems (IPSS) are increasingly dominant in several sectors. Predominant value-adding services provided for industrial assets such as production systems, electric power plants, and car fleets remote asset maintenance, monitoring, control, reconfiguration. IPSS designers lack methods tools supporting them systematically deriving technical design requirements the underlying Cyber-Physical System (CPS) services. At same time, use of Digital Twins (DTs) digital representations CPS is becoming feasible thanks to powerful, networked information technology (IT) operation (OT) infrastructures ubiquity sensors data. This paper proposes a method guiding specification implementation DT instances serve key enablers The systematic mapping continuous IT design-build-deployment cycle concept OT domain at heart applied methodology, which complemented by stakeholder-driven elicitation. contribution structured IPSS. validated on real-world cases an evaluation environment distributed
