PRIORITY DETERMINATION DEVICE

PROBLEM TO BE SOLVED: To provide a priority determination device capable of calculating priority whose accuracy is high. SOLUTION: The priority determination device 10 is provided with a priority setting means 11. (a) As for works, among works as targets of processing whose excess number of days is equal to or smaller than a prescribed value, the excess number of days calculated by subtracting a residual working time predicted to be spent until the completion of works from the number of days until the term of delivery of the works, and whose residual working time is equal to or shorter than the prescribed value, the priority setting means 11 highly sets the priority of the works in the order of the small residual working time, and as for the works which are not pertinent to conditions of (a) among the works as the targets of processing, (b) the priority setting means highly sets the priority of the works in the order of the small excess number of days.
