1. A method for monitoring a state of a physical passenger transport system using an actualized digital replica dataset (ADRD) which includes characterizing properties of components of the physical passenger transport system in a machine-processable manner after assembly and installation thereof in a building, wherein at least one detection device is arranged in the physical passenger transport system and detects changes in at least one characterizing property that is caused by wear on a traveling physical component of the physical passenger transport system, wherein the ADRD is generated by:
creating a commissioning digital replica dataset from component model datasets with target data which reproduce characterizing properties of components of the passenger transport system in a target configuration;
creating a production digital replica dataset based on the commissioning digital replica dataset by measuring actual data which reproduce characterizing properties of components of the physical passenger transport system in the actual configuration of the passenger transport system immediately after assembly and installation thereof in a building and replacing target data in the commissioning digital replica dataset with corresponding actual data; and
creating and continuously updating the ADRD based on the production digital replica dataset by modifying the production digital replica dataset during the operation of the physical passenger transport system, taking into account measured values acquired by the detection device which reproduce changes in characterizing properties of traveling components of the physical passenger transport system during its operation; in that these changes are transmitted to the ADRD as measurement data and the characterizing properties of the component model datasets affected by the transmitted measurement data are updated accordingly.
