Process control system of bus ticket booking (closed loop)

 Introduction :
Udankhatola is a domestic privatized transportation company that
runs the Buses all over the country. This is an web application
which provides Booking of tickets all over the world.
 Problem statement :
System that are using by the staff at the counter currently is an
internal system and just used to sell the bus ticket at the counter.
Customer has to go to the counter to buy bus ticket or ask for bus
schedule. Furthermore, customers need to pay cash when they buy
the bus ticket and sometimes needs to queue up long time to get the
bus ticket. Besides that, customer also not allowed to buy bus ticket
through telephone and the bus company's telephone always-busy
line .

SOLUTION
The method to solve this problem is to create
an online booking bus ticket system . Customer can buy
the book ticket over the Internet, 24 hours a day, 7 days a
week and the bus ticket can't be lost, stolen or left
behind. In addition, the online system lets the customers
check the availability of the bus ticket before they buy
bus ticket. Furthermore, customers no need to pay cash
to buy bus ticket because they can pay the bus ticket on
the traveling time.
