  • a maintenance plan generating unit that determines a maintenance date and time on and at which a throughput of a manufacturing system is maximum from among possible maintenance dates and times based on a result of a simulation in which the manufacturing apparatus that is specific on the manufacturing system is stopped at a specified maintenance date and time;

    a completion-delayed-lot calculating unit that specifies a lot whose completion is predicted to be delayed due to maintenance on the determined maintenance date and time; and

    a priority calculating unit that calculates a priority of the lot whose completion is predicted to be delayed so as to prevent waiting time of the lot during maintenance.
