Abstract
An acquisition unit is configured to acquire a measurement value of a first state quantity of a target device. A model determination unit is configured to determine a model for estimating a value of a second state quantity of the target device for each evaluation item for management of the target device. An estimation unit is configured to estimate the value of the second state quantity on the basis of the measurement value using the model determined by the model determination unit. A management unit calculates a value of the evaluation item using the value estimated by the estimation unit.

1-10. (canceled)
A management system comprising a communication device and an information processing device,
- wherein the communication device comprises:
- an acquisition unit that is configured to acquire measurement values of state quantities of a target device, the state quantities containing a first state quantity and a second state quantity which correspond one to one;
- an extraction unit that is configured to determine to transmit the measurement value of the first state quantity to the information processing device when a change of the second state quantity is less than a change of the first state quantity, to determine to transmit the measurement value of the second state quantity to the information processing device when a change of the second state quantity is greater than a change of the first state quantity, and
- a transmission unit that is configured to transmit the measurement value of the first state quantity to the information processing device when the extraction unit determines to transmit the measurement value of the first state quantity,
- wherein the information processing device comprises:
- a measurement value acquisition unit that is configured to acquire a measurement value of a first state quantity;
- a model determination unit that is configured to determine a model for estimating a value of a second state quantity of the target device for each evaluation item for management of the target device;
- an estimation unit that is configured to estimate the value of the second state quantity on the basis of the measurement value using the model determined by the model determination unit;
- and
- a management unit that is configured to calculate a value of the evaluation item using the value estimated by the estimation unit.
