Purpose – In spite of the benefits of virtual models in the building and construction industry, the full potential of these models, especially in the construction and operation phases, remains largely unrealized. With the increasing developments in information and communication technology, a number of attempts have been made to extend the use of these models, through the development of integration approaches and technologies. However, the issue of integrating the virtual model and the physical construction such as to enable bi-directional coordination, has not been adequately addressed. Thus, the purpose of this paper is to investigate the application of a cyber-physical systems (CPS) approach in enhancing bi-directional coordination between virtual models and the physical construction. Design/methodology/approach – This research employs scenario development rapid prototyping to illustrate CPS integration in the construction industry, with a particular focus on facilitating bi-directional coordination. The proof-of-concept prototype systems developed were validated using a focus group consisting of industry practitioners. Findings – Bi-directional coordination between virtual models and the physical construction has the potential to improve real-time progress monitoring and control of the construction process, tracking of changes and model updates, information exchange between the design office and the job site, real-time documentation of the as-built status of high-value components and improved sustainability practices. Originality/value – This paper adds value to the construction industry by demonstrating the application of the CPS approach in enhancing bi-directional coordination between virtual models and the physical construction through the development of system architectures, scenarios and prototype systems.

Purpose: development of a methodology for automating the process of analyzing security threats in cyberphysical systems, which is based on the study and analysis of the system architecture and possible risks of threat implementation, as well as the capabilities of the intruder. Method: the developed methodology is based on structuring information about the architectural features of cyberphysical systems. Structuring information and presenting it in the form of directories that are interconnected allows to determine the list of threats, vulnerabilities and attacks that are relevant to it based on structural and functional characteristics. When designing the database, an ontological approach was applied, which allows you to highlight concepts and their properties. Results: methodological recommendations for analyzing the security of cyber-physical systems have been developed, based on the study and assessment of vulnerabilities and security threats. The analysis of the structural and functional characteristics of the cyber-physical system is carried out and the main features from the point of view of information security are highlighted. Integration of new methods for assessing risks, identifying current threats, and developing effective recommendations for cyber-physical systems made it possible to create a knowledge base about threats, attacks, vulnerabilities of CPS. New threats to CPS have been identified, which are associated with their specific properties: mobility, use of wireless networks, location outside the controlled area. The result of the study is a product presented in the form of a knowledge base that allows you to determine the degree of threat of a threat for a given structural and functional characteristics of a cyber-physical system. Implemented automatic updating of information about vulnerabilities from open databases.

Share Information

Cyber-physical systems (CPS) extensively share information with each other, work collaboratively over Internet of Things, and seamlessly integrated with human society. Designing CPS requires the new consideration of design for connectivity where security, privacy, and trust are of the main concerns. Particularly trust can affect system behavior in a networked environment. In this paper, trustworthiness is quantitatively measured by the perceptions of ability, benevolence, and integrity. Ability indicates the capabilities of sensing, reasoning, and influence in a society. Benevolence measures the genuineness of intention and reciprocity in information exchange. Integrity captures the system predictability and dependability. With these criteria, trust-based CPS network design and optimization are demonstrated.

The Impact

Information security has been growing steadily in recent times. Every organization depends on information technology and information security of cyberphysical systems to successfully perform its work. This has become not just a condition for the stability of doing business, but the most important strategic factor for its future development, even in the current, very turbulent environment. Cyberphysical systems can contain a wide variety of entities, ranging from office networks, financial and personnel systems to highly specialized systems. The rapid development of cyber-physical systems has become due to the large number of cyberattacks, which have become one of the most powerful threats to the security of cyber-physical systems. Many studies have been conducted on the risk assessment method, and limited work has been published on quantifying the security risk of cyber-physical systems. In this paper, a technique for the risk assessing of the cyber-physical systems’ information security based on the vulnerabilities’ interconnect is proposed. Technique operates with two indicators to quantify the risk: the probability of attack success and the index of the consequences of the attack based on the graph of the vulnerability. The first indicator - the index of the probability of a successful attack is calculated taking into account the interdependencies between vulnerabilities, the second indicator when calculating the index of the consequences of the attack takes into account the impact on the physical area resulting from cyberattack. A quantitative experimental example showed whether a system risk and an optimal attack target are possible.

Different Levels

At present, an increasing number of researchers and specialists in the construction industry come to the opinion that it is advisable to use a number of technologies (BIM, Smart City, Big Data, IOT and others) in the practice of construction (in the broad sense of this concept), which are united by the concept of the Fourth Industrial Revolution. The result of the implementation of these technologies in the construction should be the transition to the widespread use of cyber-physical systems. The problem of using information technologies in construction today is not due to the lack of this process as such, but to the lack of consistency and consistency in it. Fragmentary nature of the application, inconsistency of the applied technologies at different levels of management and at different stages of the life cycle of construction projects sharply reduce the potential positive effect of informatization and building automation. At the same time, the concept of cyber-physical systems, that is, the integration at the system level of physical processes and controls has proven effective in industrial production. The approaches to ensuring the processes of designing cyber-physical building systems through the development and application of General mathematical models for the processes of data exchange and management are considered. The presented models of data exchange and management of cyber-physical building systems describe the processes implemented at each stage of the life cycle of cyber-physical building systems. Functional blocks of the considered models allow to describe the processes of data collection, storage and processing on the current and past stages of the life cycle of cyber-physical construction systems. The presented models are the elements of mathematical support of the processes of designing cyber-physical building systems, which determine the processes of information exchange and management between the structures of cyber-physical building systems of different levels of hierarchy in the full life cycle.
