1. A method for monitoring a state of a physical passenger transport system using an updated digital double dataset (UDDD) which includes characterizing properties of components of the physical passenger transport system in a machine-processable manner, wherein:
the physical passenger transport system comprises a traveling conveyor belt;
the updated digital double dataset is constructed from component model data records which comprise data which were determined by measuring characterizing properties on the physical passenger transport system after the physical passenger transport system was assembled and installed in a building;
the physical passenger transport system comprises has at least one detection device that detects a load profile of the conveyor belt during operation;
this load profile is transmitted as measurement data to the updated digital double dataset and, using a set of rules, characterizing properties of the component model data records affected by the transmitted measurement data are redetermined;
the characterizing properties of the affected component model data records are then updated with the redetermined characterizing properties; and
based on the monitoring, changes and change trends in the updated characterizing properties of the traveling conveyor belt and their influence on components of the conveyor belt and on the components interacting with these components can be tracked and evaluated based on the updated digital double dataset by calculations and/or by static and dynamic simulations.
