The Third Methode to Explore the Boat Schedule of big Long River

In this paper we assumpt three groups of boats are supposed to launch each day, including, group 1 comprised of motorized boats of different durations, group 2 comprised of oar-powered rubber crafts of different durations and group 3 motorized boats of different durations. By following this schedule, no contact will take place. In this case, the carrying capacity of the river is 238, which means at least 238 campsites should be provided. Besides, the total visits in 6 months are 3163. In contrast, no one is more superior to the other. The former schedule will provide even spread of boat types in terms of propulsions; while the latter ensures the maximal visits to the river.
