1. A method for generating a process model modeling a manual mode procedure instance of a plant process, the procedure instance comprising a related sequence of operational actions, including the steps of:
providing a plurality of log events of a plurality of operational actions of the plant process;
selecting a plurality of related sequences of manual mode operational actions from the plurality of log events;
filtering the plurality of related sequences of manual mode operational actions according to an individual plant section;
identifying a sequential order from the plurality of filtered related sequences of the manual mode operational actions;
determining statistical properties of values of related process variables and/or statistical properties of values of related set point changes to each sequential ordered manual mode operational action from the plurality of filtered related sequences of the manual mode operational actions;
generating the process model of the manual mode procedure instance by arranging related manual mode operational actions with the sequential order of each operational action assigned with the statistical properties of the values of related process variables and/or assigned with the statistical properties of the values of the related set point changes,
wherein the process model is configured to provide guidance through execution of corresponding manual procedures using the generated process model.
