“…The Knowledge Base pillar accumulates the base knowledge that can be used during the design process and provides technical tools and models. Examples of the Knowledge Base can be found in the literature [34], where it is used to support digital twins and containing domain ontology and its associated rules. In the current work this pillar is used to support the design of the whole Collaborative CPS including the DTs.…”

The growing smartification of devices and systems, combining physical and virtual parts, offers a great potential to improve the daily life of people through the establishment of context-rich environments. Cyber-Physical Systems (CPS), embedding collaborative features, can be considered as one of the key enablers of such environments, providing support for life quality improvement. Besides the general aim of the conventional CPS, further aspects related to co-existence and collaboration among different heterogeneous and autonomous components within a system, are in the scope of Collaborative CPS. These systems allow looking at the technical and organisational challenges from the perspective of interconnected and jointly acting entities. Such entities can be the physical devices or their virtual representations, which are called Digital Twins (DT), understood as digital replicas of physical assets. However, a DT provides more than just a digital simulation of the physical device or process, including reasoning and prediction mechanisms. This work is devoted to the discussion of how Digital Twins can be used in the design, development, and functioning of Collaborative CPS. As such, a design approach is suggested and illustrated with a smart home scenario.

“…After several years of in-depth research in the field of virtual modeling, simulation techniques, data analysis and visualization, and since the evolution of information and communications technologies digital twins saw their applications extended to several fields. Some of these fields are chiefly maintenance and product health management PHM [14], realtime monitoring [15], ergonomics [16], education [17], production systems management [18], smart grids [19], energy efficiency and more recently healthcare [20]. This multidisciplinary aspect that the concept acquired as a result of its exploitation for numerous and completely different purposes, and due to its combination with multiple concepts and technologies that included some of digital transformation major actors such as augmented reality, big data and industrial internet of things (IIOT) [21], new requirements and criteria were added for its successful implementation within industrial plants.…”

Industrial world today is experiencing its fourth industrial revolution. Predecessor of the automation industry, Industry-4.0 adds a layer of autonomy, intelligence and advanced connectivity to complex industrial systems. This layer creates an interactive and dynamic bridge between virtual systems and physical systems with their upward constraints and requirements in a constantly changing physical environment. Digital twins fall into the category of advanced concepts and technologies that enhance this connectivity. Several projects have been launched in Morocco by the government, industrialists and research communities, initiating the digital transformation of Moroccan industrial manufactories and companies. This paper comes within this framework, firstly to highlight the great potential that digital twins can offer for Moroccan industrial context enhancement, secondly to identify the challenges that can hinder the integration and development of digital twins in Moroccan industrial environment.

“…Digital twin technology is used to describe and model the characteristic, behaviour, formation process, and performance of physical entities. At the same time, advanced sensors, industrial network, IoT, big data analysis, machine learning, and other technologies are used to realize and complete production process monitoring, forecasting, data mining, and other functions [4][5][6][7].…”

Aiming at the problems of irrational allocation of resources, low efficiency caused by unbalanced production line layout, and slow production line upgrade of the smart factory, this paper builds a real physical smart factory platform through the optimal control strategy and uses the GRAFCET algorithm to optimize the logistics scheduling during the actual system operation. The genetic algorithm is used to optimize the layout effect of the production line; the digital twin technology is used to provide predictive analysis technical support for the upgrading and reengineering of the production line. Through the analysis and comparison of the production capacity and equipment utilization of the physical smart factory and the virtual smart factory processing scheme, practice shows that the design of the digital twin system can effectively improve the effect and accuracy of the lean production method in the production process reorganization. Quantitative analysis of manufacturing industry provides powerful theoretical and technical support.
