Introduction
My research interests primarily lie on the field of Applied Probability and Stochastic Processes and Operations Research. More precisely, Mathematical Modelling and its Analysis of Queueing/Stochastic Storage Systems, Applications of Game Theory in Queues, Communication Systems, and Computer Networks.

Article
We consider a single server queueing-inventory system under (s,Q) replenishment strategy with working vacations, vacation interruptions and lost sales. The server provides service at a lower rate during working vacations than while in normal mode of service. If a working vacation realizes while providing service in that mode, then the server contin...

We consider a correlated queueing-inventory system with Markovian arrival of customers, phase type distributed service time and Markovian lead time. Items in each cycle have a common life time. Before the realization of this, a purchased item in a cycle can be cancelled in that cycle itself provided inventory level has not dropped to zero. Common l...
Article
This paper considers an M/M/1/1 queueing-inventory system with retrial of unsatisfied customers. Arrivals taking place when server is busy, proceed to an orbit of infinite capacity. From the orbit, the head of the queue alone retires to access the server. Failed attempts to access an idle server with positive inventory results in the retrial custom...

We attempt to derive the steady-state distribution of the queueing-inventory system with positive service time. First we analyze the case of servers which are assumed to be homogeneous and that the service time follows exponential distribution. The inventory replenishment follows the policy. We obtain a product form solution of the steady-state dis...

In this paper we analyze a two-stage queueing-inventory system, wherein the first stage is an infinite capacity, queue. Customers arrive in a Poisson fashion; service rendered in batches of maximum size K. The second stage has a finite capacity buffer. Each stage is managed by one single server. If the number of customers in the first queue is less...

A production inventory system, with the item produced being admitted (added to the inventory) with probability δ as well as an item from the inventory supplied to the customer with probability γ at the end of a service, is considered in this paper. The control policy followed is of the (s, S) type. We obtain joint distribution of the number of cust...

A queueing-inventory system, with the item given with probability γ to a customer at his service completion epoch, is considered in this paper. Two control policies, (s,Q) and (s,S) are discussed. In both cases we obtain the joint distribution of the number of customers and the number of items in the inventory as the product of their marginals unde...

A detailed review of inventory models involving positive service time is given. These include classical and retrial cases. A detailed review of inventory models involving positive service time is given. These include classical and retrial cases. Also contributions to production inventory with service time is indicated towards the end. In addition d...

I'm currently working on game theoretic queueing models with attached inventory. Main objective of this project is to explore the strategic behavior of customers and social optimization of queueing-inventory systems.
