Formal methods are one of the efficient tools to verify and validate designs for different kinds of systems. Smart systems are attracting researchers' attention due to the rapid spread of new technologies all over the world. Modeling a smart system requires connecting heterogeneous subsystems together to build it. Our contribution to this work is in focusing on using formal methods to prove that a design model meets its specifications. We have chosen to design a smart school building system due to the lack of research in this particular area, and to prove that formal methods are appropriate for different systems applications. In this paper, we have used UML diagrams and the formal specification language TLA+ to design a smart school building system. We validate our design using the TLC model checker. The smart school system has many subsystems connected together including a secure access system, lighting control system, climate control system, and smoke detection system. Safety is a very important attribute in this system. Our goal is to have a smart system that satisfies its functional requirements as well as any non-functional requirements like safety. The system provides safety for employees and students in the smart school.

Current infrastructures in modern cities are highly dependent on complex software-intensive systems, which are composed of many elements, including software, sensors, actuators, and processes. Citizens and managers are also important stakeholders in these systems, as they provide data, provide and retrieve information and also manage the many systems that control the city infrastructures’. UML has been often considered for designing these types of systems, mostly with focus only on designing the software elements of the system. However, these infrastructures systems are composed of many more elements than software, including processes, constraints, sensors, networks, laws and further documents. SysML is a UML profile that has gained attention in past years, as SysML also models systems elements that are not software. In this paper, the main idea is to describe a SysML profile for modeling smart cities applications, which is useful as it specifies common elements of a city as native elements of system design. The profile, named SmartCitySysML, extended from SysML Requirements, Sequence and Block Definition diagrams in order to model system and software elements for smart cities. Design of a road traffic control system regarding a group of intersections is used as a case study. As a result, SmartCitySysML facilitates the use of common elements in smart city infrastructures and provides a visual representation to assess quality of diagrams from a practical point of view.
