A Multi-Server Heterogeneous Queuing-Inventory System with Class-Dependent Inventory Access

A finite source multi-server inventory system with service facility

A single server perishable inventory system with N additional options for service

This article presents a perishable (s; S) inventory system under continuous review at a service facility in which a waiting hall for customers is of nite size M. The arrival instants of customers to the service station constitutes a Poisson process. The life time of each items is assumed to be exponential. All arriving customers demand the rst "essential" service, whereas only some of them dema...

State Dependent Multi channel Queuing System with Ordered Entry

In the present study, we analyze the multi-channel service system with ordered entryfrom finite-source and finite-storage at each channel. The arrival and service rates are assumedto be state dependent. The steady state probabilities of the system are obtained by usingChapmann-Kolmogorov equations. Some other performance indices viz. utilization of servers,expected number of units in the system...

A multi-objective inventory model for deteriorating items with backorder and stock dependent demand

Classical deterministic inventory models consider the demand rate to be either constant or time-dependent but independent from the stock status. However, for a certain type of inventory, the demand rate may be in-fluenced by the stock level. Also in many real-life problems, some products such as fruits, vegetables, phar-maceuticals and volatile liquids continuously deteriorate to evaporation, o...

A Perishable Inventory System with Repeated Customers and Server Interruptions

In this article, we present a continuous review perishable inventory systemwith a service facility. The service facility consists of a single server and a finite waiting room. If the arriving primary customer finds the waiting hall is empty and the server is idle, he immediately joins the service. The demanded items are issued by a server after some random time due to service on it. We assume t...
