ABSTRACT
Bulk arrival general service retrial queueing system is analyzed in this paper. Server provides two phases of service-essential and optimal. After each service completion, the server searches for customers in the orbit. Customers may balk or renege at particular times. Accidental and active breakdown of the server is considered. The repair of the failed server starts after a random amount of time known as delay time. After repair the server continues the service of the interrupted customer or waits for the same customer. The necessary and sufficient condition for the system to be stable is presented. By applying supplementary variable technique, the steady state distributions of the server state and the number of customers in the orbit are obtained. Numerical examples are presented to illustrate the influence of the parameters on several performance characteristics

    In this paper we discuss a queueing system with service interruption. The service gets interrupted due to different environmental factors. Here it is assumed that interruption due to only one factor is allowed at a time. Further we assume that while in interruption no other interruption befalls...

    Optimal control of many-server heterogenous service systems with service times that have a special hyper-exponential distribution, denoted by $H_{2}^{*}$, which is a mixture of an exponential distribution and a unit point mass at 0, is considered. A static priority policy that assigns priorities...

    We study a queueing network with a single shared server that serves the queues in a cyclic order. External customers arrive at the queues according to independent Poisson processes. After completing service, a customer either leaves the system or is routed to another queue. This model is very...

    We propose a static service differentiation policy for a single-server queueing system serving homogeneous customers. We show that by randomly assigning customers different service grades with different service rates, the average waiting time can be reduced without affecting the mean service...

    This work considers a many-server retrial queueing system in which nonpersistent (impatient) customers with i.i.d., generally distributed service times and independent sequences of i.i.d., generally distributed inter-attempt times. A newly arrived customer attempts to obtain service immediately...

    Whereas the buffer content of batch-service queueing systems has been studied extensively, the customer delay has only occasionally been studied. The few papers concerning the customer delay share the common feature that only the moments are calculated explicitly. In addition, none of these...
