Two-Commodity Markovian Inventory System with Compliment and Retrial Demand

Two-Commodity Markovian Inventory System with Set of Reorders

This article examines a two commodity substitutable inventory system—two different brands of super computers under continuous review. The demand points for each commodity are assumed to form independent Poisson processes. The reordering policy is to place orders for both the commodities when the total net inventory level drops to any one of the prefixed levels with prescribed probability distri...

Coordinated and Joint Ordering Policies for Two Commodity Inventory System

Markovian Retrial Queues with Two Way Communication

In this paper, we first consider single server retrial queues with two way communication. Ingoing calls arrive at the server according to a Poisson process. Service times of these calls follow an exponential distribution. If the server is idle, it starts making an outgoing call in an exponentially distributed time. The duration of outgoing calls follows another exponential distribution. An ingo...

A two-commodity perishable inventory system

We present a two-commodity perishable stochastic inventory system under continuous review at a service facility with a finite waiting room. The maximum storage capacity for the i–th item is fixed as Si (i = 1, 2). We assume that a demand for the i–th commodity is of unit size. The arrival instants of customers to the service station constitutes a Poisson process with parameter λ. The customer d...

A Tandem Queue with Two Markovian Inputs and Retrial Customers

A tandem retrial queue consisting of two stations is studied. The first station has a single server. An input flow at the first station is described by the Markovian Arrival Process ( MAP ). If a customer from this flow meets the busy server, it goes to the orbit of infinite size and tries its luck later on in exponentially distributed random time. The service time distribution at the first sta...
