Zusammenfassung:In the present invention, a maintenance strategy presentation device (1) has: a simulation unit (50) for inputting cumulative damage derived from the predicted value of operation data of an object to be maintained to a service life model that defines a reliability index for each cumulative damage to the object to be maintained, and thereby calculating the current reliability index and determining, in each period and according to the magnitude relationship between the current reliability index and the reliability index of an execution criteria parameter (91), whether or not to execute preventive maintenance with the current reliability index; an optimization calculation unit (70) for evaluating simulation result data (51) outputted by the simulation unit (50) using a prescribed evaluation index and updating the execution criteria parameter (91) so as to optimize the evaluation result; and a display control unit (80) for displaying the simulation result data (51) or the evaluation result thereof on a display device.
