Erratic demands have traditionally shown complexity in inventory management and forecasting. Several organisations, especially in multi-product manufacturing systems with intermittent demand high level of variability and uncertainty, assume suitable estimators are put in place to forecast demand. This forces them to pay attention to controlling the inventory of a system. The forecasted demand i...

This paper develops a stochastic general equilibrium inventory model for an oligopoly, in which all inventory constraint parameters are endogenously determined. We propose several systems of demand processes whose distributions are functions of all retailers’ prices and all retailers’ service levels. We proceed with the investigation of the equilibrium behavior of infinite horizon models for in...

In this study we empirically estimate the e¤ect of local market conditions on inventory performance of U.S. automobile dealerships. We show that the in‡uence of competition on a retailer’s inventory holdings can be separated into two mechanisms. First, the entry or exit of a competitor can change a retailer’s demand (a sales e¤ect). Second, the entry or exit of a competitor can change the amoun...

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...

We consider a continuous review (s ;S ) inventory system at a service facility with two types of service and finite waiting hall. The maximum inventory level is S units. The waiting hall of size is N . We assume that the demands arrive according to a Poisson process with rate λ(> 0) and demands only single unit at a time. The demanded item is delivered to the customer after a random time of ser...

Nowadays, competitive market creates the necessity of quality improvement in different levels of supply chains (SCs). This paper contributes to the SC coordination literature and proposes a bilateral coordination contract for optimizing pricing decisions along with quality improvement decisions in different echelons of a real case of a cell phone SC. The SC comprises a manufacturer who deals wi...

This article presents a perishable inventory system under continuous review at a service facility in which a waiting area for customers is of finite size M . The authors assume that the replenishment of inventory is instantaneous. The items of inventory have exponential life times. It is assumed that demand for the commodity is of unit size. The service starts only when the customer level reach...
