ON a  QUEUEING SYSTEM WITH GENERALIZED COXIAN-2 SERVICE AND OPTIONAL GENERALIZED COXIAN-2  VACATION

Abstract. We study the  steady state behaviour of  a batch arrival single server queue in which the first service with  general service times  is compulsory and the second service with general service times  is optional. We term such a two phase service as generalized Coxian-2 service. Just after completion of a service the server may take a vacatiosn of random length of time with general vacation times . After completion of the first phase of vacation the server may or may not take the second optional vacation with general vacation times . We term this two phase vacation as optional generalized Coxian-2 sever vacation. We obtain  steady state probability  generating functions for the queue size at a random epoch of time in explicit and closed forms. Some particular cases of interest  including some known results  have been derived.
