A Standards-based Approach for Cross-Domain Modelling of Smart City System Architectures

The inherent complexity of systems in the domain of smart cities demands a suitable modelling framework to facilitate development and interdisciplinary communication. In the domain of smart grids, the Smart Grid Architecture Model (SGAM) framework provided means for coping with complexity whilst supporting a cross-disciplinary understanding of modelled systems. Similar approaches exist for the automotive and industry domains. As a complex smart city system may combine various application domains, interoperability between applied modelling frameworks is imperative to simplify cross-domain collaboration. Therefore, to be suitable, a modelling framework needs to target the concerns of stakeholders from the smart city, whilst simultaneously enabling interoperability between all connected application domains. The presented approach is a standards-based systems engineering framework, implemented as Domain Specific Language (DSL) and based upon the Smart City Reference Architecture Methodology (SCRAM). Moreover, the DSL is used to model a particular system solution to evaluate its applicability.
