- In-depth analysis of organisational structures for digital twin ecosystemsPublication . Melo, Victória; Pires, Flávia; Barbosa, José; Prieta, Fernando de la; Leitão, PauloThe Digital Twin (DT) plays a crucial role in the digital transformation era by providing a bidirectional synchronized digital representation of an asset, capable of performing real-time monitoring, simulation, and data analysis. Generally, DTs are designed as single units following a centralised approach. However, this paradigm is evolving towards DT ecosystems, consisting of a network of multiple interconnected DTs. The benefits of such ecosystems depend on their intended purpose and application, which are strongly influenced by the design and structural configuration adopted during implementation. This paper aims to analyse different organisational structures, namely centralised, hierarchical, heterarchical, and holonic, for the design, development, and implementation of DT ecosystems, assessing their benefits and challenges across a set of aspects. A case study of a modular conveyor transfer system was used to test the different organisational structures, supporting the comparative analysis and the discussion of the research challenges related to this topic.
- Ten years of asset administration shell: developments, research opportunities, and adoption challengesPublication . Sakurada, Lucas; Prieta, Fernando de la; Leitão, PauloOver the past decade, the Asset Administration Shell (AAS) has emerged as a cornerstone of digital transformation in Industry 4.0 (I4.0), providing a standardized approach to managing digital representations of industrial assets. With 2025 marking approximately ten years since its introduction, this article aims to provide a comprehensive analysis and discussion of AAS development over the past decade, potential research opportunities, and the challenges associated with its adoption. To this end, the study combines a literature survey with an examination of specifications from key organizations, such as the Plattform Industrie 4.0 and the Industrial Digital Twin Association (IDTA), which play a central role in the AAS standardization and development. A key insight from this survey is that AAS is progressing toward becoming a game-changer in realizing I4.0. Unlike a decade ago, AAS has now reached a level of maturity that enables its increasing adoption, supported by specifications and standards, dedicated development platforms for its implementation, and several examples in the literature showing a wide range of applications. Additionally, research opportunities for AAS align with emerging industrial trends and contribute to addressing them. However, several challenges must still be addressed to facilitate the widespread adoption of the AAS.
