Zusammenfassung: | PROBLEM TO BE SOLVED: To appropriately select survey respondents. SOLUTION: An survey system 10 determines initial survey respondents based on recovery rate prediction model information showing a correspondence relationship between an elapsed time from the start of survey and a predicted recovery rate showing the rate of the number of recovery with respect to the number of survey respondents. Furthermore, on the basis of the actual number of recovery after the lapse of a predetermined time from the start of survey and the predicted number of recovery corresponding to the predetermined time in the recovery rate prediction model information, the survey system 10 subtracts the actual number of recovery from the predicted number of recovery to calculate the insufficient number of recovery, and determines the additional survey respondents corresponding to the insufficient number of recovery.
