Abstract
In an information processing device according to the present invention, a statistics estimation unit estimates a value of a state quantity by using a statistical model constructed based on values of past state quantities of a target device. A physical estimation unit estimates a value of a state quantity by using a physical model constructed based on design data of the target device. A specification unit specifies a value to be used to manage the target device from the value estimated by the statistics estimation unit and the value estimated by the physical estimation unit based on deterioration of the target device with time.
Claims8
An information processing device comprising:
- a statistics estimation unit configured to estimate a value of a state quantity by using a statistical model constructed based on values of past state quantities of a target device;
- a physical estimation unit configured to estimate a value of a state quantity by using a physical model constructed based on design data of the target device;
- and
- a specification unit configured to specify a value to be used to manage the target device from the value estimated by the statistics estimation unit and the value estimated by the physical estimation unit based on an amount of values of the past state quantities used to construct the statistical model.
An information processing method comprising:
- estimating a value of a state quantity by using a statistical model constructed based on values of past state quantities of a target device;
- estimating a value of a state quantity by using a physical model constructed based on design data of the target device;
- and
- specifying a value to be used to manage the target device from the value estimated using the statistical model and the value estimated using the physical model based on an amount of values of the past state quantities used to construct the statistical model.
A non-transitory computer readable medium comprising a program causing a computer to:
- estimate a value of a state quantity by using a statistical model constructed based on values of past state quantities of a target device;
- estimate a value of a state quantity by using a physical model constructed based on design data of the target device;
