To effectively utilize work information acquired by maintenance of an instrument in a plant, an apparatus is provided, which includes an acquisition unit that acquires work information about at least one of a calibration or an adjustment performed on the instrument in a plant; an extraction unit that extracts a plurality of data elements to be included in output information having a predetermined output format from the work information; and a generation unit that generates the output information from the plurality of data elements.

A method for automatic calibration of a device for actuating at least one element to be actuated in a structure, the actuation device comprising at least one actuator configured to actuate at least one corresponding element to be actuated. The method comprises the steps of: controlling the movement of each actuator to place each element in a predetermined reference position; and for each actuator: controlling the movement of the actuator in a first direction; if the value of a parameter associated with the actuator exceeds a first reference value, controlling the movement of the actuator in a second direction, opposite to the first direction; if the value of the parameter exceeds a second reference value, recording the position occupied by the actuator as the position of a first mechanical stop of the actuator.
