Measure the arrival and service distributions. Describe the queue discipline and the operating characteristics. The queuing paper should be two to three typed pages plus any tables or graphs. Choose a real queuing system to observe. Common examples involving people are lines in stores, banks, restaurants, and theaters.
Cars do the waiting in common situations like drive up windows and freeway on ramps.
Carefully define the arriving population and what constitutes an arrival. Define the server, which may actually be several people or machines working together. Define when service begins and ends. Your observations should cover at least twenty arrivals and ninety minutes or at least forty arrivals over a shorter period. Make a trial run before collecting your final observations.
