1. An apparatus for determining a maintenance plan, comprising:

  • a maintenance action and cost database to store a plurality of maintenance actions executable for a system and a plurality of maintenance costs each differently corresponding to each of the plurality of maintenance actions;

    a reference strategy database to store a reference strategy determining a maintenance action to be executed for the system, based on a degradation or an output of the system;

    a fault model database to store a fault model stochastically representing an occurrence of the degradation;

    a simulation unit configured, if the system is respectively maintained by each maintenance action at a first timing, if the system is degraded by the fault model from the first timing to a predetermined timing, and if the system is maintained by the reference strategy from a second timing after passing a predetermined period from the first timing to the predetermined timing, to set at least one search timing in a search period from the first timing to the second timing, and to calculate a maintenance action value of each maintenance action at the search timing, based on the output and a maintenance cost corresponding to the maintenance action by which the system is maintained from the first timing to the predetermined timing; and

    a maintenance plan search unit configured to select an optimum maintenance action from the plurality of maintenance actions, based on the maintenance action value of each maintenance action.
