“…Smart factories digitize the physical layout, business processes, and products, and integrate them in the digital world [3,4]. This improves the efficiency of processes [5], create better products [6], and enables data-driven decisions [7]. Smart manufacturing encompasses recent technologies such as the Internet of Things (IoT), artificial intelligence (AI), augmented reality (AR), big data analytics, and so on to enable the digital transformation of factories [8][9][10][11].…”

Due to the fourth industrial revolution, manufacturing companies are looking to implement digital twins in their factories to be more competitive. However, the implementation of digital twins in manufacturing systems is a complex task. Factories need a framework that can guide them in the development of digital twins. Hence, this article proposes a small-scale digital twin implementation framework for manufacturing systems. To build this framework, the authors gathered several concepts from the literature and designed a digital twin subsystem model using a model-based systems engineering (MBSE) approach and the systems engineering “Vee” model. The systems modelling defines the digital twin components, functionalities, and structure. The authors distribute most of these concepts throughout the framework configuration and some concepts next to this general configuration. This configuration presents three spaces: physical, virtual, and information. The physical space presents a physical layer and a perception layer. The information space has a single layer called middleware. Finally, the virtual space presents two layers: application and model. In addition to these layers, this framework includes other concepts such as digital thread, data, ontology, and enabling technologies. This framework could help researchers and practitioners to learn more about digital twins and apply it to different domains.

The article considers the main methods for increasing the efficiency of aviation maintenance and repair (MRO) processes organization. A brief overview of these methodologies is presented and their key principles are highlighted. Based on the analysis of existing methodologies, a management decision-making technique based on the Stage-Gate project management technology and simulation modeling methods was proposed. This technique makes it possible to ensure the information availability for the after-sales services organization from other processes in a single information environment and make decisions on the transition to the next gate based on simulation models of aircraft maintenance at various gates.
