Abstract: A scheduling result file (103) indicates that one or more processes are assigned to each of a plurality of process steps to be executed sequentially. A target specification section (120) specifies a target process that is a process performing computation and an identical-type process that is a process assigned to a process step executed after a process step to which the target process has been assigned and performing computation which is identical in type to the target process among processes in the scheduling result file. A destination specification section (130) specifies, as a destination step, a process step that enables a computing unit to be shared between the target process and the identical-type process when the target process is assigned. A scheduling change section (150) changes description of the scheduling result file to description in a state in which the target process has been assigned to the destination step.

Abstract: A tilting angle control device includes pressure sensors. Each of the pressure sensors outputs to a control unit a pressure command signal corresponding to an operation amount. The control unit outputs to an electromagnetic proportional control valve a pressure control signal corresponding to the pressure command signal, and the electromagnetic proportional control valve outputs to a tilt adjustment mechanism pilot pressure corresponding to the pressure control signal. The tilt adjustment mechanism adjusts a tilting angle of a variable displacement pump such that the tilting angle becomes an angle corresponding to the pilot pressure. A pilot pressure sensor detects the pilot pressure to output a pressure feedback signal to the control unit. The control unit calculates the pressure control signal based on the pressure feedback signal and the pressure command signal and performs feedback control of the pilot pressure.
