    Abstract: A work machine rental management device, a work machine rental management method, and a work machine rental program that can appropriately determine a rental cost of a work machine. A controller of a rental management device acquires a total operating time and a maintenance record of a work machine during a rental period, a cumulative operating time of the work machine at the start of the rental period, and maintenance management information including a content of maintenance required for the work machine and a cost required for the maintenance from a ROM. The controller determines a maintenance cost required for the maintenance required during the rental period based on the total operating time, the cumulative operating time, and the maintenance management information, and determines the rental cost during the rental period based on the determined maintenance cost, the total operating time, and the maintenance record.

    Abstract: A control device, a control method, and a control program of a propeller for ship that enable the ship to move accurately in parallel are provided. When a joystick is tilted in a predetermined direction, a system controller performs a second control to make a ship move in parallel in accordance with corrected control parameters while correcting control parameters of outboard motors for moving the ship in the predetermined direction, on condition that wave height at a current position of the ship is equal to or higher than a threshold value, determines whether the control parameters are appropriate from a moving state of the ship when the ship is moved in accordance with the control parameters, on the condition that the wave height is lower than the threshold value, and rewrites the control parameters so that the ship moves in parallel when the control parameters are not appropriate.
