Behaviorial analysis of a heterogeneous feedback queue system

The paper studies the behavior analysis of a network of queue system having two heterogeneous service channels wherefeed-backing are allowed for defective items. The arrivals and departures at each channel follows poissonlaw. Connectingthe various probabilities, the differential difference equations have been formed. The marginal mean queue size for each channel and for the entire system has been explored. On the basis of graphical study the behavior of the system has been studied. An effort has been made to analyze how the system behaves on changing the parameter.
