Abstract
A state estimation method includes a first step of preparing a plurality of first estimation models estimating a state of an object to be monitored based on a state variable measured with respect to the state of the object to be monitored, a second step of preparing a second estimation model estimating, from among the plurality of first estimation models, which one of the first estimation models estimates the state of the object to be monitored with the highest accuracy based on the state variable measured with respect to the object to be monitored or a state variable measured with respect to a utilization device that runs by using the object to be monitored, and a third step of outputting a result of estimation of the state of the object to be monitored of the one first estimation model estimated by the second estimation model.
