“…Thus, a digital twin is a digital representation of a product, process or service used to monitor, analyze, and improve its performance; "a bridge between the physical and digital world". The drivers of the development of the city's digital twins are technologies of "Big Data" and the "Internet of Things" (IoT) [15].…”

The development of digital twins of the urban ecosystem is gaining popularity and is the mainstream of the digital development of the territories of the world. Already today, there are domestic developments for the creation of digital twins, including the urban ecosystem. The aim of the article is to provide a theoretical description of the essence of the digital twin of a city and an overview of existing platforms for creating digital twins of an urban ecosystem to ensure the quality of life of the population. Research objectives: to identify the prerequisites for the creation of digital twins; to determine the essence of the definitional basis of the digital twin in the context of existing theoretical analogs; to characterize the conceptual foundations of creating digital twins of the urban ecosystem in Russia and the world, to identify the advantages of their development to maintain the quality of life of the population; to give an idea of the methodology for the development and functioning of digital twins of the urban ecosystem; to conduct a comparative analysis of the capabilities and functionality of digital platforms and technologies for the development of digital twins of the urban ecosystem; to conduct a comparative analysis of the existing digital twins of the urban ecosystem of the world. As a result of the study, data on existing domestic digital platforms and technologies for the development of digital twins of the urban ecosystem were obtained, their comparative analysis was carried out, advantages were identified, and the possibility of achieving technological leadership and competitiveness in this area in the world market was determined. Descriptive, analytical, and comparative methods were used as research methods. The results of the study showed that the use of digital twins of the urban ecosystem will allow municipal authorities to obtain effective levers of management, and the population -to ensure a high quality of their own life.

“…This approach aims at achieving equivalence by directly replicating sensor data into the model. The sensor data may be used to update the state of the model either at a fixed frequency [2] or dependent on the availability of data or event [14,37]. The aim is to ensure the state of the model reflect that of the real system.…”

A digital twin contains up-to-date data-driven models of the physical world being studied and can use simulation to optimise the physical world. However, the analysis made by the digital twin is valid and reliable only when the model is equivalent to the physical world. Maintaining such an equivalent model is challenging, especially when the physical systems being modelled are intelligent and autonomous. The paper focuses in particular on digital twin models of intelligent systems where the systems are knowledge-aware but with limited capability. The digital twin improves the acting of the physical system at a meta-level by accumulating more knowledge in the simulated environment. The modelling of such an intelligent physical system requires replicating the knowledge-awareness capability in the virtual space. Novel equivalence maintaining techniques are needed, especially in synchronising the knowledge between the model and the physical system. This paper proposes the notion of knowledge equivalence and an equivalence maintaining approach by knowledge comparison and updates. A quantitative analysis of the proposed approach confirms that compared to state equivalence, knowledge equivalence maintenance can tolerate deviation thus reducing unnecessary updates and achieve more Pareto efficient solutions for the trade-off between update overhead and simulation reliability.

“…Finally, a previous work of co-authors [9] builds agent-based DTs for the healthcare domain. In [8] instead, a whole MAS is used to implement the DT of a whole city transportation system. A similar approach is taken in reference [40] to realise the concept of "communicating material" in the energy supply business domain.…”

Digital Twins (DTs) are rapidly emerging as a fundamental brick of engineering cyber-physical systems, but their notion is still mostly bound to specific business domains (e.g. manufacturing), goals (e.g. product design), or application domains (e.g. the Internet of Things). As such, their value as general purpose engineering abstractions is yet to be fully revealed. In this paper, we relate DTs with agents and multiagent systems, as the latter are arguably the most rich abstractions available for the engineering of complex socio-technical and cyber-physical systems, and the former could both fill in some gaps in agent-oriented engineering and benefit from an agent-oriented interpretation-in a cross-fertilisation journey.
