Abstract

An operation-draft-plan creation apparatus according to an embodiment of the present invention includes an acquirer, a simulator, and an operation-draft-plan creator. The acquirer acquires a deterioration model regarding performance of a similar measurement target. The similar measurement target is a measurement target considered to be similar to an operation target. The deterioration model is calculated on the basis of a measurement value of the similar measurement target. The simulator performs a simulation concerning deterioration of the performance of the operation target on the basis of the deterioration model regarding the performance of the similar measurement target and a use case example assumed for the operation target. The creator creates an operation draft plan on the basis of a result of the simulation. The operation draft plan indicates an implementation period of maintenance work performed on the operation target.
