During the last decade, the smart grid (SG) concept has started to become a reality, mainly thanks to the technical progress achieved in telecommunications, informatics and power electronics, among other domains, leading to an evolution of the traditional electrical grid into an intelligent one. Nowadays, the SG can be seen as a system of smart systems that include cyber and physical parts from different technologies that interact with each other. In this context, intelligent buildings (IBs) constitute a paradigm in which such smart systems are able to guarantee the comfort of residents while ensuring an appropriate tradeoff of energy production and consumption by means of an energy management system (EMS). These interconnected EMSs remain the objective of potential cyber-attacks, which is a major concern. Therefore, this paper conducts a survey, from a multidisciplinary point of view, of some of the main security and privacy issues related to IBs as part of the SG, including an overview of EMS, smart meters, and the main communication networks employed to connect IBs to the overall SG. Future research directions towards a security enhancement from both technical and human perspectives are also provided.

“…Furthermore, SG can be seen as a cyber-physical system of systems (CPSoS), due to the diversity and complexity of its components, whose interoperability must be ensured [11]. The varied interactions among the elements inside the SG must be managed through interdisciplinary and integrated systems engineering approaches [12].…”

“…MBSE can play an important role in describing complex systems and their relevant lifecycle and integration when combined with Systems Modeling Language (SysML, which is a systems engineering adaptation of unified modeling language originated by software development) 6 or any other modeling language. MBSE can facilitate communication by connecting all the information produced during the system development 7 . In addition, a noticeable number of complex systems that are going to be developed may be exposed to cyber‐attacks in the future and MBSE can be implemented to alleviate the probable risks existing in this regard.…”

Currently, a wide range of newly designed devices are based on high-end quantum technologies. To successfully design a quantum system, it is necessary to appropriately address the increasing complexity which exists in the development procedure of the system. A suitable approach to deal with this problem is to employ systems engineering models and integrate them with domain engineering tools. The model-based systems engineering (MBSE) methodology is commonly used to analyze, design, manufacture, and test various complex systems. In this paper, the MBSE approach is chosen for the development of quantum dot solar cells as a typical quantum system and to deal with the complexity existing in this procedure. The analysis, manufacturing, and verification, validation, and testing (VV&T) for this system are described using SysML in Cameo Systems Modeler software to represent the role of models in this regard. Then a detailed design is performed in MATLAB and integrated with SysML to identify how changing various parameters during the system development process affects the overall system performance. This technique facilitates the communication between different engineering teams and helps to manage the complexity in the entire system lifecycle.

Hierarchical scheduling frameworks are a new scheduling paradigm where multiple system schedules are integrated (one-within-another). HSFs presents a multi-layered complexity problem that system engineers are struggling to contain. A promising trend in the aerospace and defense industry is to employ Digital Engineering’s Model-Based Systems Engineering (MBSE) to deal with the complexity of HSFs. MBSE permits the abstraction of application-specific details that can radically speed up system design exploration. Thus, this paper investigates how the output from an HSF algorithm can be converted into an MBSE modeling language that enables architectural exploration for resource allocation. The Unified Modeling Language (UML) Modeling and Analysis of Real-Time and Embedded Systems (MARTE) Profile is the chosen unified modeling language of MBSE. The modeling language is used with an HSF application for demonstration purposes. The approach in this paper seeks to limit tool use by combining an inline verification method (Genetic Algorithm) with a new MBSE workflow.
