1. An operation support apparatus comprising:
at least one memory configured to store instructions and time-series data obtained by measuring states of a target system controlled according to a plurality of operations performed by an operator, and operation information, the operation information being a set of at least one of the plurality of operations and a time, and
at least one processor configured to execute the instructions to:
specify a plurality of change points in a change trend of the states from the time-series data, and specify each of a plurality of time windows as one of a plurality of operating modes in the target system, the plurality of time windows being separated at at least one of the plurality of change points; and
extract, for each of the plurality of time windows, a set of operations performed at a time included in that time window from the operation information, generate an operating-mode operation set in which the operating modes corresponding to the respective time windows are associated with the extracted set of operations, and store the generated operating-mode operation set in the storage unit.
