Analysis of heterogeneous feedback queue system with at most one revisit

In this paper a queuing model has been developed for a system in which a service channel commonly linked with two service channels which are heterogeneous. A customer is allowed to revisit the service channels one time and the probability of second visit has been taken different than the probability for the first visit. The arrival and departure process follows poisson distribution at each service channel. The main objective of the paper is to analyze the behaviour of the heterogeneous feedback queue system when probability of second visit has been changed and when customers arrive at different arrival rates at different service channels.
