Optimizing the Passenger Throughput at an Airport Security Checkpoint

We consider the problem how to optimize the passenger throughput at an airport security checkpoint. Generally speaking, for an arrival passenger to board the flight, she/he must receive security check. First, check his/her identification and then check his/her baggage and body in a queue according to the FIFO rule. By applying the queue theory we model the security check process as a two-chase multi-server series and parallel queue model with two input queue and use the computer simulation to evaluate the performance of current queue system. Furthermore, we obtain the improved queue system by modifying the parameters of current queue system.
