Draw the business process flow chart for the given process below.

EYAH airport operates 24 hours a day, 7 days a week, but there is a passenger density between 08:30 to 18:30 in the system. There are inter-arrival times, first security check point, process times for passengers who check in or not, and second security check point.

Arrivals to the system are possible with 3 different transportation vehicles (car, taxi and bus).

1-3 people by car, 1-2 people by taxi and 15-30 people by bus enter the system. The interarrival times of the vehicles are as follows; every 2.5 minutes a car, every 5 minutes a taxi, and every 30 minutes a bus.

It has been determined that 1/6 of the arrivals to the airport is to the international terminal and 5/6 to the domestic terminal.

Passengers are divided into three types: (i) elderly (or disabled), (ii) VIP, and (iii) normal passengers based on their status. Transaction times for the elderly and VIP passengers are 30% less.

5% of all those who come by car or taxi are counted as VIP passengers and 8% of all arrivals are elderly or disabled passengers.

If there is a VIP or old passenger, they are put forward in the queue, and also the priority of the queue is aligned as VIP, old or disabled and normal passenger. Since VIP and elderly passengers are dealt with fast track, their processing time is 30% less than a normal passenger.

The last ticket check (final check point) before boarding to the plane was determined as exponentially distributed with rate 3 seconds.

Passengers arriving at domestic and international flights must firstly pass through an external security check point which is the first check point before entering to the airport.

There are 4 x-ray devices at the external security control point. First, passengers come to security point 1. If the number of passengers waiting in this first X-Ray line is more than 6, the 2^nd X-ray device is put into use. If the number of passengers waiting in this line is more than 8, and if there are less than 6 passengers waiting in the first X-Ray, passengers are directed to the 2^nd X-Ray. If it is full, the 3^rd X-Ray device is opened. The capacity of each X-Ray is 10 people. External security transaction time is distributed as 36 + 124 * beta (1.35, 0.946) sec. 5% of the people come to the airport are not passengers and come to the airport for different purposes.

Not to check-in	38+93*Beta(0.719,1.01) sec.
Check-in	23+27*Beta(0.678,0.797) sec.

2 counters are reserved for people who have Check in at domestic flights and 8 counters for those who do not check-in but do different operations. For international flights, 2 counters are reserved for international flight passengers and 4 counters for those who do not check-in but do other operations.

For domestic lines: There are 3 internal security checkpoints. Security-1 has a capacity of 3 passengers, security-2 has a capacity of 5 passengers. Internal security transaction time is distributed with Gamma distribution and the function is 34 + GAMMA (27.7, 1.15) sec. As in the external security point, if the number of waiting passengers exceeds the amount of capacity given, the third security point is put into service.

For international flights, 2 internal security control point is available. The first security point has a capacity of 3 passengers. If more than 3 passengers are waiting in the first security check point, then, second security point is put into service.

People who finish all their required processes and wait for the flight boarding time, spend their waiting time in 3 different ways. (i) in the waiting hall, (ii) cafe, and (iii) duty free. Moreover, the time that a passenger spend at the waiting area is distributed with exponential distribution with mean 5 minutes. People, whose boarding time comes, exit the system after the last ticket check control. It is assumed that there is one last ticket control point for each line.
