  In an ongoing project, a cooperation between the TU/e and the Dutch
Department of Waterways and Public Works (Rijkswaterstaat in Dutch, abbreviated
to RWS) is established. The project focuses on investigating applicability of
synthesis-based engineering in the design of supervisory controllers for
bridges, waterways and tunnels. Supervisory controllers ensure correct
cooperation between components in a system. The design process of these
controllers partly relies on simulation with models of the plant (the physical
system). A possible addition to this design process is digital twin technology.
A digital twin is a virtual copy of a system that is generally much more
realistic than the 2D simulation models that are currently used for supervisory
controller validation. In this report, the development of a digital twin of the
Swalmen tunnel that is suitable for supervisory control validation is
described. The Swalmen tunnel is a highway tunnel in Limburg, the Netherlands.
This case study is relevant, because the Swalmen tunnel will be renovated in
2023 and 2028. These renovation projects include updating controlled subsystems
in the tunnel, such as boom barriers and traffic lights, and updating the
supervisory controller of the tunnel. The digital twin might be useful to aid
the supervisory controller design process in these renovation projects.
