anybody ? please
Hi,
may someone help me with an exercise ?
I give exams tommorow and this exercise is always fallen.
Let 2 classes of customers arrive in a queueing system with poisson with arrival rate l1 and l2.
Also there are 2 servers to serve these customers.
If a customer belongs to class a is served by server 1 or 2 in exponential time with mean service time 1/m.
If the customer belongs to class b , uses both servers and is served with m mean serving time.
A customer who does not find free server , go out from the system.
I have to make the markov diagram and to write the equations which describe the system.
Thanks a lot
PS: I apologise for my english. I hope to understand.
