PROBLEM TO BE SOLVED: To easily recognize the time band of a high working rate and the time band of a low working rate in each machine kind at a glance. SOLUTION: A management device 140 is provided with a working rate calculation means 142 for calculating the working rate of each machine kind for each prescribed time band, a working rate storage means 145 for storing the calculated working rate for each machine kind, and output means 147 and 148 for outputting the transition conditions of the working rates of the plurality of machine kinds based on stored information together. A time band specifying means 142 for specifying the time band in which the working rate is equal to or higher than a prescribed working rate and/or equal to or lower than the prescribed working rate for each machine kind on the basis of the stored information of the working rate storage means 145 is provided. The output means 147 and 148 make the output form of the time band specified in the time band specifying means 142 different from the output form of the time band other than the specified time band and output the transition conditions of the working rate.
