摘要

PROBLEM TO BE SOLVED: To realize an accurate prediction of an interval between a service delivery and a next service delivery.SOLUTION: An interval prediction device performs the steps of: calculating a cumulative probability of an interval between a service delivery and a next service delivery; generating normal-time probability distribution in which the cumulative probability becomes equal to or more than a reference probability and abnormal-time probability distribution in which the cumulative probability becomes less than the reference probability; calculating a prediction value of the interval using the normal-time probability distribution; and recalculating the interval using the abnormal-time probability distribution if a reference interval has elapsed after a service delivery.
