Abstract: A scheduling system according to the present disclosure includes a measurement unit that acquires at least brightness data indicating intensity of reflected light of a beam by performing measurement, a scheduler that schedules a measurement date on and time at which the measurement unit performs the measurement, and a measurement data evaluation unit that holds in advance reference brightness data, the reference brightness data being the brightness data acquired by the measurement unit in the past when weather was fine, and evaluate whether a difference between the brightness data acquired by the measurement unit and the reference brightness data is greater than or equal to a threshold value. When a result of the evaluation by the measurement data evaluation unit indicates that the difference is greater than or equal to the threshold value, the scheduler reschedules the measurement date on and time at which the measurement unit performs the measurement.
