A Preemptive Priority Queue with Accessible Batch Service and Heterogeneous Arrivals and with Vacation
In this paper a single server preemptive priority queuing system consisting of two types of customer units with Poisson arrival, exponential service time distribution and exponential vacation is analyzed. Two type of customer units of which higher priority units of unlimited Poisson input are served by bulk service rule and limited Poisson input of low priority units served singly. The bulk ser...
متن کاملA Preemptive Priority Queue as a Model with Server Vacations
We derive the performance measures for non-priority customers in a priority single-server queue with two types of Markovian arrival processes (MAPs). One type of customers has preemptive resume (or repeat) priority over the other. We regard the model with two types of MAP arrivals as an MAP/SM/l queue with only non-priority customers arrivals, semi-Markovian service times and some server vacati...
متن کاملNotes on ‘ Performance Analysis Of The System Contents In A Discrete - time non - preemptive Priority Queue With General Service Times
2. The server is busy serving a class 2 packet during slot k. This can only be the case if at the beginning of the last “start slot” (this is start slot l, in which the service of the currently served packet started) there were no class 1 packets in the system. Otherwise, a class 1 packet would have gone into service at that time instead of a class 2 packet, because of the priority scheduling. ...
متن کاملInfinite-server Queues with Batch Arrivals and Dependent Service Times
Motivated by large-scale service systems, we consider an infinite-server queue with batch arrivals, where the service times are dependent within each batch. We allow the arrival rate of batches to be time-varying as well as constant. As regularity conditions, we require that the batch sizes be i.i.d. and independent of the arrival process of batches, and we require that the service times within...
متن کاملWorking Vacation Queue with Second Optional Service and Unreliable Server
An M/M/1 queueing system with second optional service and unreliable server is studied. We consider that the server works at different rate rather than being idle during the vacation period. The customers arrive to the system according to Poisson process with state dependent rates depending upon the server’s status. All customers demand the first essential service whereas only some of them dema...
