Travelers arrive at the main entrance door of an airline terminal according to an exponential interarrival-time distribution with mean 1.6 minutes, with the f rst arrival at time 0. The travel time from the entrance to the check-in is distributed uniformly between 2 and 3 minutes. At the check-in counter, travelers wait in a single line until one of f ve agents is available to serve them. The check-in time (in minutes) follows a Weibull distribution with parameters ! 5 7.78 and " 5 3.91. Upon completion of their check-in, they are free to travel to their gates. Create a simulation model, with animation (including the travel time from entrance to check-in), of this system. Run the simulation for a single replication of 16 hours to determine the average time in system, number of passengers completing check-in, and the time-average length of the check-in queue. Put a text box in your model with the numerical results requested. kel01315_ch04_121-206.indd 194 05/12/13 3:29 PM Modeling Basic Operations and Inputs 195
