Vacation models deal with a very important class of real life congestion situations
encountered in day-to-day as well as in industrial scenario. A vacation in queueing context …

This paper considers a finite-buffer discrete-time GeoX/GY/1/K+ B queue with multiple
vacations that has a wide range of applications including high-speed digital …

We present a model for assigning server time slots to different classes of patients. The
objective is to minimize the total expected weighted waiting time of a patient (where different …

In the past, many researchers have analyzed queueing models with batch service. In such
models, the server typically postpones service until the number of present customers …

In Bulk service queueing models, customers are served in batches, the batches may be of
fixed length or variable length. Sometimes, the service rate may depend on the number of …

Classification of items as good or bad can often be achieved more economically by
examining the items in groups rather than individually. If the result of a group test is good, all …

Over the last two decades there has been considerable growth in digital communication
systems which operate on a slotted system. In several applications, transmission of packets …

In most of the service systems considered so far in queuing theory, no fresh customer is
admitted to a batch undergoing service when the number in the batch is less than a …

This paper analyzes a discrete-time single-server infinite-(finite-) buffer bulk-service queues.
The inter-arrival times of successive arrivals are assumed to be independent and …

It is well known that discrete-time queues are more appropriate than their continuous-time
counterparts for modelling computer and telecommunication systems. This paper is …
