Abstract: This paper deals with the steady state analysis of unreliable batch arrival feedback retrial queue with k stages of service and Bernoulli vacation policy, where the busy server is subjected to breakdown due to the arrival of negative customers. After completion of the i^th, (i = 1, 2, ..., k) stage of service, the customer may have the option to choose (i + 1)^th stage with probability θ_i, with probability pi may join into orbit as feedback customer or may leave the system with probability 1 − θ_i − p_i = q_i, if the service is successful. The server takes Bernoulli vacation after the service completion. Arriving positive customers may balk (or renege) the system at particular times. After completion of the service, vacation or repair, the server searches for the customer in the orbit or remains idle. The system is solved by using the supplementary variable method and numerical illustrations are discussed.

Keywords: Bernoulli vacation; feedback; retrial; balking; reneging; negative customer; k stage service; orbital search.
