A Two-Stage Model Queueing with No Waiting Line between Channels [PDF]

open access: yesMathematical Problems in Engineering, 2013
We consider a new queuing model with sequential two stations (stages), single server at each station, where no queue is allowed at station 2 and with no restriction at station 1. There is a FCFS service discipline in which the input stream is Poisson having rate . The service time of any customer at server () is exponential with parameter .
