Abstract: A loading work assistance system includes a loading-progress-degree calculation unit that calculates a degree of progress of loading work performed on a transport vehicle located in a construction site by a loading vehicle, a determination unit that determines whether or not the degree of progress is equal to or more than a degree-of-progress determination threshold value, and a transport vehicle starting instruction unit that instructs the transport vehicle standing by to be started in a case where the degree of progress is equal to or more than the degree-of-progress determination threshold value.

Abstract: A work machine management apparatus includes: a working element identification information acquiring unit acquiring working element identification information indicating replacement of a working element; a flow rate setpoint acquiring unit acquiring a flow rate setpoint of a hydraulic oil for the working element; a pressure setpoint acquiring unit acquiring a pressure setpoint of the hydraulic oil for the working element; a working element operation information acquiring unit acquiring the acquired flow rate setpoint, the acquired pressure setpoint and operation information of the working element; and a working element actual operation information calculator calculating actual operation information containing an actual operation duration of the working element based on the information acquired by each of the working element identification information acquiring unit, the flow rate setpoint acquiring unit, the pressure setpoint acquiring unit and the working element operation information acquiring unit.
