Digital Twin Models in CBM Apps. Functionality Description and Features Analysis

The goal of digital twins (DT) is to replicate physical equipment and systems in the digital world by effectively integrating data, models, and decision support systems, promising a step change in productivity and sustainable performance. Despite recent developments in DT solutions, several issues remain to be addressed before the benefits of this technology for maintenance can be realized. For example, it is necessary to generate a better conceptual basis, to facilitate the functional description of the applications, etc. This paper contributes to explain, in a practical way, the functionality and structure of these applications within digital configurations for maintenance management. It proposes a generic framework for the functional description of a DT designed for intelligent maintenance and, in addition, lists a series of characteristics that must be fulfilled when developing these tools, according to the relevant scientific literature. This paper is an excerpt from different contributions of the authors on this topic.
