Abstract
PROBLEM TO BE SOLVED: To improve accuracy in predicting deterioration of a battery.
SOLUTION: An information processing device 100 acquires time sequential data indicating temporal changes of battery deterioration amounts of a terminal device A and a terminal device B. The information processing device 100 generates models 101, 102 or the like concerning the terminal device A and generates models 103, 104 or the like concerning the terminal device B. The information processing device 100 generates one or more patterns where a use form 1 is associated with a use form 2, for each line segment included in straight lines or polygonal lines indicated by the models 101-104 or the like. The information processing device 100 generates combinations 111-114 or the like by combining the patterns. The information processing device 100 predicts deterioration of a battery for each terminal device based on a dispersion of inclinations of line segments for each use form in the respective combinations such as the combinations 111-114 or the like.
