Chart3 Schedule where Y=425<br />

(ⅲ)Arrangement of separate campsite sets if <strong>the</strong> proportions of all trip types are<br />

given<br />

As shown above in chart3, <strong>the</strong> number of “forgone loss” can be ignored compared<br />

with <strong>the</strong> <strong>to</strong>tal number of days available of all campsites, namely180 ∗ Y. In o<strong>the</strong>r<br />

word, <strong>the</strong> <strong>schedule</strong> enables <strong>the</strong> trips <strong>to</strong> occupy nearly all campsites for all days in a<br />

six months period, and obviously it can be regarded as <strong>the</strong> best s chedule.<br />

Fur<strong>the</strong>rmore, if we ignore <strong>the</strong> “forgone loss” and <strong>the</strong> <strong>to</strong>tal number of a specific trip<br />

180∗n i<br />

type i can be calculated asm i = [<br />

]. Therefore n duration of type i ican be determined<br />

by m i .<br />

We can now design a <strong>schedule</strong> with given proportions of all trip types. This is<br />

because:<br />

Given proportions of all trip types→<strong>the</strong> ratio of <strong>the</strong> <strong>to</strong>tal number of any two trip<br />

types m i<br />

m j<br />

→<strong>the</strong> ratio of <strong>the</strong> campsites n i<br />

n j<br />

→combine with ∑ i n i = Y → n i<br />

(Note this makes sense because <strong>the</strong> river agency is supposed <strong>to</strong> provide with a<br />

variety of trip types and <strong>the</strong> flexibility <strong>to</strong> control <strong>the</strong> proportions of all trip types is<br />

even more meaningful, since <strong>the</strong> river agency can refer <strong>to</strong> his<strong>to</strong>rical data and design a<br />

<strong>schedule</strong> with proportions of all trip types compatible with previous demands of<br />

<strong>to</strong>urists.)<br />

Therefore we only need <strong>to</strong> design a <strong>schedule</strong> <strong>to</strong> allocate all Y campsites <strong>to</strong> n i orbits<br />

respectively.
