A management system includes a storage unit that stores schedule information that indicates schedules of a plurality of tasks to be performed by the same flight vehicle. The schedule information includes types of the plurality of tasks, date/times of the plurality of tasks, and locations at which the plurality of tasks are to be performed. When the types, the date/times, and the locations that are included in the schedule information stored in the storage unit satisfy an integration condition, an integration unit integrates the schedules of the plurality of tasks. An output unit outputs integrated schedule information indicating the schedules of the integrated tasks.
