2. Airport baggage screening system

 2.1. System overview Every bag originated from check-in counters or early-baggage storages is transferred to a screening subsystem to receive mandatory (level-1) security inspection. The layout of a typical screening subsystem is illustrated in Fig. 1(a). A screening subsystem consists of several homogeneous screening lines. The arrived bags are distributed to each screening line according to a load balancing strategy. Each screening line, indexed by l2L ¼ f1; …; mg where m is the total number of lines, is normally comprised of one EDS machine and several queue conveyors. The system state observed by the k-th arriving bag is denoted by qk ¼ ðqk;1; qk;2; …; qk;l ; …; qk;mÞ, where qk;l is the number of bags waiting in EDS line l. We let Nl Q denote the number of queue conveyors (limited waiting space) at the l-th line. It is obvious that physical constraint qk;l Nl Q must hold. Screening is carried out on a FCFS basis for each queue. Jockeying amongst queues is not possible. If the screening machine outputs a safe signal, the X-rayed bags are transported to the sortation area. Otherwise, it can be cycled back for a second checking, or transferred to another checkpoint with more stringent inspection (level-2) (Blejcharova et al., 2012). We assume that all checking results are “pass” and only level-1 screening is applicable, i.e., no recycle for questionable bags. In principle, the control logic of any subsystem within a BHS is dealt with by a PLC. The PLC communicates with sensors and actuators to fulfil all the necessary functionalities of baggage handling (Dai and Vyatkin, 2012; Wu et al., 2013). In the case of screening subsystem, the PLC performs a load balancing algorithm to divert each bag to screening line l based on the system states collected from sensors. The start and stop of each queue conveyor is also controlled by the PLC.
