Design and Process Metamodels for Modelling and Verification of Safety-Related Software Applications in Smart Building Systems

Smart building is an example of a cyber-physical system that adopts the internet of things in order to every component, each person, and every process can be accessed from everywhere. This paper proposes a novel software engineering approach for the design of the smart building systems, namely, the metamodels for modelling and verification of smart building safety-related software applications. Two different metamodels are proposed: the design metamodel and the process metamodel. Their use allows not only to define a design structure and safety properties of smart embedded devices but also to model and validate corresponding safety scenarios. To demonstrate an effectiveness of the proposed approach, a case study is done to model and verify a prototype of a safety-related software system in a smart building.
