Abstract This thesis consider some queuing models to determine the measures of performance of a model. The most important measures are the waiting time in the queue and the size of the queue. The queue we are studying is the Beit-eba crossing check-point for both people arriving and people departing from Nablus City. A comparison is made in order to determine the best fit model among two assumed models and the one under study(real one)using a suitable tool of simulation “SimQuick” which performs process simulation within the Excel spreadsheet environment. To prove that we got good results for our study. We started by an assumed queue model and solve it analytically by the known formulas of queuing theory. Next, we use simulation by "SimQuick" to compare results, which showed a good agreement between analytical solution and simulation. The study showed that the single-channel queue is more efficient than the multiple-channels queues. |
