Abstract: A demand prediction device derives a first exponential function indicating the time-series transition of the number of bookings until a service provision time point for a first customer group based on the transition of the number of bookings until a time point t1 for the first group. A demand prediction device derives a second exponential function indicating the time-series transition of the number of bookings until a service provision time point for a second customer group based on the transition of the number of bookings until a time point t2 for the second customer group different from the first group. The demand prediction device generates information supporting a service providing entity based on the time-series transition of the number of bookings until an analysis target time point for the first customer group indicated by the first exponential function and that for the second customer group by the second exponential function.
