A Steady State Analysis of Tri-Cum Biseries Feedback Queue Model

This paper presents a system of tri-cum biseries feedback queue models linked with a common server. The arrival of customers follows a Poisson distribution with the facility of at most two visits to any of the servers. If any customer is unsatisfied or any job required feedback then he may revisit the system for satisfaction. A customer will enter the system or exit the system with different probabilities in every visit. Various queue parameters are computed with the help of generating function technique and other statistical methods. The implementation of the model in a practical situation has also been studied. Validation study of the model is done with the help of a numerical and particular case.
