摘要： A management device includes a memory and a processor coupled to the memory. The processor is configured to collect measurement data from sensors installed in respective measurement locations including outside an installation room in which an information processing device is installed, in a gas path in an air-conditioning system of the installation room, and inside the installation room, the measurement data being data measured by the respective sensors. The processor is configured to store the measurement data in the memory. The processor is configured to delete unnecessary data from the measurement data stored in the memory. The processor is configured to calculate a predicted value in at least one measurement location of the measurement locations on basis of the measurement data from which the unnecessary data is deleted. The predicted value is a value of data predicted to be measured by any of the sensors.
