Consider an airport security system. Determine the system model considering that there are two classes of customers – regular an
d VIP (business, elite…), and considering the bag check, personal check, extra checking when something triggers it at the X-ray machine, etc. The objective of the simulation for such a system would be the delay experienced in the system.a. Determine the system entities - draw a block diagram of the system. b. What are the main attributes of the system?

The logical expressions are
- (X NOR Y ) OR Z ⇒
- (A NAND B) AND NOT C ⇒
<u>Logical expression 1</u>
X and Y are linked by the NOR gate.
So, we have:
X NOR Y
The X NOR Y is linked to Z by the OR gate.
So, we have:
(X NOR Y) OR Z
Hence, the logical expression is (X NOR Y ) OR Z ⇒
<u>Logical expression 2</u>
A and B are linked by the NAND gate.
So, we have:
A NAND B
The A NAND B is linked to C by the AND gate.
So, we have:
(A NAND B) AND C
Hence, the logical expression is (A NAND B) AND NOT C ⇒
