In this article, the queuing theory is applied to study the problem of journey arrangements. Primarily, with the analysis of stochastic processes, we draw the conclusion that the arrival of tourists conforms to the Poisson distribution and the camping time also complies with the general independent and identically distributed law. As each camp can be seen as the selectable service counter, we determine the M / G / s / s model in the premise of the queuing theory. Then, a higher precision simulation model is established which makes fewer assumptions to ensure the practicability. So when the camp sites have been determined before, this model exhausts all possible situations, and solves the problem of occupied camp by adopting the semaphore mechanism. Finally based on the simulation model program, we get the maximum group which can be accepted after provided with camping spots.
