DEMAND PREDICTION APPARATUS, DEMAND PREDICTION METHOD, AND DEMAND PREDICTION PROGRAM |
| 摘要 |
A demand prediction apparatus (10) includes: an activity number acquisition unit (161a) that acquires the number of activities of a target that a demand is predicted; a replacement factor calculation unit (161b) that calculates a replacement factor of the target that a demand is predicted based on a first curve that expresses a change of a probability of occurrence of a failure in a time series and a second curve that expresses a change of a probability of occurrence of a failure in a time series; and a demand prediction unit (161c) that calculates a demand for the target that a demand is predicted based on the number of activities acquired at the activity number acquisition unit (161a) and the replacement factor calculated at the replacement factor calculation unit (161b). |

1. A demand prediction apparatus comprising:
an activity number acquisition unit being configured to acquire a number of activities of a target for which a demand is predicted; a replacement factor calculation unit being configured to calculate a replacement factor of the target for which a demand is predicted based on a first curve that expresses a change of a probability of occurrence of a failure in a time series and a second curve that expresses a change of a probability of occurrence of a failure in a time series; and a demand prediction unit being configured to predict a demand for the target based on a number of activities acquired at the activity number acquisition unit and the replacement factor calculated at the replacement factor calculation unit. |
