Abstract In this work, we consider a novel single-server retrial queue with event-dependent arrival rates. Contrary to other related works, the primary customers’ rates depend on last realized event, which refers either departure, or an of type, when customer arrives during busy period, compared others. Our motivation stems from modeling service systems, in customers express their willingness j...

A compound exponential-server timing channel consists of a number of infinite-buffer single-server queues in tandem. The message is coded in the sequence of arrival times to the first queue. We consider the performance of a structurally simple mismatch decoder that is the maximumlikelihood decoder for a single queue.

This paper presents a model for a discrete time single server G-queue with two types of independent arrivals, namely positive and negative. The arrival of negative customer to queueing system removes one customer from the head of the queue (RCH), which causes server breakdown. The repair of the server is noninstantaneous and after repair server is assumed as good as new. The interarrival times ...

This investigation deals with single server queueing system wherein the arrival of the units follow Poisson process with varying arrival rates in different states and the service time of the units is arbitrary (general) distributed. The server may take a vacation of a fixed duration or may continue to be available in the system for next service. Using the probability argument, we construct the ...

This paper analyzes a renewal input  working vacations queue with change over times and Bernoulli schedulevacation interruption under (a,c,b) policy.The service and vacation times are exponentially distributed.The server begins service if there are at least c units in the queue and the service takes place in batches with a minimum of size a and a maximum of size b (a
