Analysis of classical retrial queue with differentiated vacation and state dependent arrival rate.

open access: yesRatio Mathematica, 2021
In present paper we have introduced the concept of differentiated vacations in a retrial queueing model with state dependent arrival rates of customers. The arrival rate of customers is different in various states of the server.
