A system for handling a production disturbance/opportunity event includes a network having data processing units running a MES software for controlling/monitoring a production process operating production components. A production modeler defines a plant model of the production process, and a production scheduler generates an executable production schedule for the execution of operating procedures for the production components. A production executor executes the production process following the generated executable production schedule, and a production disturbance/opportunity event identifier detects a production disturbance event and identifies a production opportunity event which allows to maintain an efficiency of the production process at least as close as possible to an efficiency given by the executable production schedule as originally generated by the production scheduler. The production scheduler re-calculates an amended executable production schedule incorporating the identified production opportunity event, and the production executor executes the production process now following the re-calculated executable production schedule.
