In a thermal load estimation device, a process in which a state estimating unit estimates a state amount indicating a state of a target area at an estimation target time by using measurement data obtained by measuring a state amount of the target area, air conditioner operation data indicating an operation state of an air conditioner disposed in the target area, and a thermal load of the target area estimated by a thermal load estimating unit, and a process in which the thermal load estimating unit estimates the thermal load of the target area by using the measurement data, the air conditioner operation data, and an estimation value of the state amount of the target area estimated by the state estimating unit are alternately performed, so that a thermal load likely to be the thermal load of the target area at the estimation target time is estimated.

A machining condition searching method includes: generating a machining condition to be set in a machining device; collecting a machining state; collecting the machining result performed under the machining condition; calculating an evaluation value of the machining on the basis of the machining result; constructing an evaluation value prediction model predicting, on the basis of the machining condition, the machining state, and the evaluation value, an evaluation value corresponding to the machining condition that has not been tried; and constructing the evaluation value prediction model on the basis of a change degree in the relationship between the machining condition and the evaluation value, and performs weighting based on the machining state on the evaluation value prediction model. The machining condition to be tried next is generated using a predictive value of the evaluation value. Each of the above processes is repeatedly performed until it is determined to end a search.
