1. A method for monitoring a process engineering installation, the method comprising:
measuring actual value(s) of at least one operating parameter of the process engineering installation occurring during operation of the process engineering installation,
determining values of the at least one performance parameter of the process engineering installation, using a model of the process engineering installation, from the actual value(s) of the at least one operating parameter of the process engineering installation measured during operation of the process engineering installation,
determining comparative values of the at least one performance parameter of the process engineering installation, using the model, from setpoint values of the at least one operating parameter, and
determining at least one performance gap of the operation of the process engineering installation based on mutually corresponding values and comparative values of the at least one performance parameter,
wherein the at least one operating parameter is selected from flow of a medium in the process engineering installation, a temperature of a component of the process engineering installation, a temperature of a medium in the process engineering installation, a composition of a medium in the process engineering installation, and/or a pressure of a medium in the process engineering installation;
determining an improvement measure for the at least one performance gap; and
providing the improvement measure via a communication means.
