Queing Theory

Background Notes for Solving the Case Queuing Quandary Queuing system is angiotensin converting enzyme of the quantitative techniques that is in most demand in alteration of business sectors like computer nedeucerking, telecom industry, share trading, melodic line industry, banking, call centers and so on. What you have studied in lectures is uncomplicated Poisson Arrival- Exponential Service queues with single server or multi servers, finite or infinite population queues. These are very round-eyed queues where you have seen few algebraically simplified formulae. These are not the cases in real life. The probability distributions could be different for reaching as well as service (you need to usance probability formulae learnt in SMRM); queues could be combination of parallel and serial queues; there could be priority customers; holding capacity in queue could be limited; balking (you may not join long queues), jockeying (jumping between queues) or reneging (leave queue if you call in its taking long time) of the queue may be common. In many cases you need to develop the model and solve part fundamental theory of Birth-Death process of queue. However, many common situations could be approximated to Poisson Arrival- Exponential Service queues.

As discussed above, many times probability of waiting beyond certain time could be a decision factor. This is the case in Queuing Quandary. We need to use probability formulae. These are provided to you by faculty. Purpose of this note is to inform theoretical basis for these formulae. Now there are two events that determine your waiting and associated probability in a queue. unitary is arrival of the customer and other is completing service to a customer. If there are two independent events; one at an exponential graze ? and another at an exponential rate ?. In such a case by theory of probability of joint distributions we can show that these two events overtake together at an exponential rate ? + ?. (I wont trouble you with the proof.
