1. A management device comprising:
a central processing unit (CPU); and
a memory storing a program,
the CPU executing the program to
acquire operating history data for an equipment device in a prescribed time period, and
classify, based on the acquired operating history data, an operating pattern of the equipment device in the prescribed time period and
the classifying the operating pattern including
calculating a first operating pattern in a first time period before a first time point that virtually splits the prescribed time period and a second operating pattern in a remaining second time period,
changing the virtual split time point to a second time point based on a unit time,
calculating a degree of change in the operating pattern using a third operating pattern in a third time period before the second time point and a fourth operating pattern in a fourth time period after the second time point in the prescribed time period when the virtual split time point is changed to the second time point,
calculating, as a split time point, a time point where the degree of change satisfies a prescribed condition for the prescribed time period, and
dividing and classifying the operating pattern of the equipment device at the calculated split time point.
