Abrégé

In order to monitor the condition of a machine, current operating data relating to the machine are continuously captured and are taken as a basis for continuously simulating a current operating behavior of a machine component by a concurrent simulation module. Furthermore, performance values quantifying a current performance of the machine component are continuously derived from the simulated operating behavior and are stored over time. In addition, a performance normal value is regularly determined on the basis of a multiplicity of performance values which were derived earlier. The operating data and/or the performance values are monitored in order to determine whether a predefined first change pattern occurs. Detection of the first change pattern then causes a performance reference value to be updated with the current performance normal value. In addition, the respective current performance values are continuously compared with the current performance reference value in each case.
