Bottleneck Detection of Security Checking Process for Airport Throughput Optimization

Abstract

There exists a trade-off between high throughput of passengers at airport security checkpoints and passenger safety. Our task is to optimize the throughput with the constraint of safety. First we define a couple of assumptions for a typical security checking system. Second, we create a bottleneck-finding model to predict the probability of congestion using grey system theory. Finally, we find that belongings-removal step is the bottleneck of security checking process by applying apagoge on each possible step.
