“…Most of the existing literature on agent-based CPSs and DTs in manufacturing is limited to conceptual models [25,44,63], top-down approaches [46,51,54,62], static complexity for optimal routing strategies without considering uncertainty in lead times or resources (i.e. dynamic complexity) [2] and data-driven approaches [59,20].…”

“…A multi-agent system component and a semantic engineering component are integrated for the development of the DT approach. Moreover, in the area of dynamic scheduling for smart manufacturing, conceptual models [44] and top-down approaches [12,62] for the development of DTs using agents have been proposed. Similarly, in the context of production systems, Dittrich & Fohlmeister [6] proposed a cooperative multi-agent system using reinforcement learning to handle the complexity of order scheduling and overcome the local optimisation problem.…”

“…This means the development of a DT must commonly satisfy these features which are aligned with the generic definition of DTs. Some examples on that, Zhang et al [18] present a dynamic scheduling application based on digital twin agents for scheduling and optimizing workshop tasks. Fang et al in [19] present research on scheduling job shop tasks using digital twins.…”

The rapid emerging technologies in various fields permitted the creation of simulation tools. These tools are designed to replicate physical systems in order to provide faster, cheaper and more detailed illustrative analysis of the physical system. In this regard, the concept of digital twins has been introduced to generally define these simulation tools. In fact, and according to the creator of the digital twin term Micheal Grieves, a digital twin is defined as a physical system, a digital replica of the physical system and information flow between the former parts. This definition is simple and generic for describing digital twins and yet, holistic. This broad definition creates a challenge for developers who target the development of such applications. Therefore, this paper presents a paradigm for architecting digital twins for manufacturing processes. The approach is inspired by the definitions of the ISA95 standard and the onion concept of computer applications to create multi-layer and multi-level concepts. Furthermore, and to satisfy the different required features by industries, the approach considers a multi-perspective concept that allows the separation of the digital twin views based on functionality. This paradigm aims at providing a modular, scalable, reusable, interoperable and composable approach for developing digital twins. Then, an implementation of the approach has been introduced using an ontology-based system and the IEC61499 standard. This implementation has been demonstrated on a discrete manufacturing assembly line.

“…However, production practice requires more information, especially the semantic correlation between key elements such as landscapes, forests, and fields [4][5][6]. The DTs model is becoming more and more popular in the infrastructure industry [7][8][9]. It can drive changes in our way of life, and not just the technological advantages that people talk about, the DTs model will also drive the development of the entire infrastructure industry [10][11][12].…”

To understand the current application and development of 3D modeling in Digital Twins (DTs), abundant literatures on DTs and 3D modeling are investigated by means of literature review. The transition process from 3D modeling to DTs modeling is analyzed, as well as the current application of DTs modeling in various industries. The application of 3D DTs modeling in the elds of smart manufacturing, smart ecology, smart transportation, and smart buildings in smart cities is analyzed in detail, and the current limitations are summarized. It is found that the 3D modeling technology in DTs has broad prospects for development and has a huge impact on all walks of life and even human lifestyles. At the same time, the development of DTs modeling relies on the development and support capabilities of mature technologies such as Big Data, Internet of Things, Cloud Computing, Arti cial Intelligence, and game technology. Therefore, although some results have been achieved, there are still limitations. This work aims to provide a good theoretical support for the further development of 3D DTs modeling.
