Validity and precision of estimates in the classical newsvendor model with exponential and rayleigh demand

Halkos, George; Kevork, Ilias - Volkswirtschaftliche Fakultät, … - 2012

In this paper we consider the classical newsvendor model with profit maximization. When demand is fully observed in each period and follows either the Rayleigh or the exponential distribution, appropriate estimators for the optimal order quantity and the maximum expected profit are established...

Evaluating alternative estimators for optimal order quantities in the newsvendor model with skewed demand

Halkos, George; Kevork, Ilias - Volkswirtschaftliche Fakultät, … - 2012

This paper considers the classical Newsvendor model, also known as the Newsboy problem, with the demand to be fully observed and to follow in successive inventory cycles one of the Exponential, Rayleigh, and Log-Normal distributions. For each distribution, appropriate estimators for the optimal...

Forecasting the optimal order quantity in the newsvendor model under a correlated demand

Halkos, George; Kevork, Ilias - Volkswirtschaftliche Fakultät, … - 2013

This paper considers the classical newsvendor model when, (a) demand is autocorrelated, (b) the parameters of the marginal distribution of demand are unknown, and (c) historical data for demand are available for a sample of successive periods. An estimator for the optimal order quantity is...

On the convexity of the cost function for the (Q,R) inventory model

Halkos, George; Kevork, Ilias; Tziourtzioumis, Chris - Volkswirtschaftliche Fakultät, … - 2014

In this paper we investigate the convexity of the annual total cost function for the Hadley & Whitin (1963) continuous review (Q,R) inventory model with backorders and fixed lead-time, when the reorder point is non-negative and the cost per unit backordered is used to calculate the expected...

Evaluating alternative frequentist inferential approaches for optimal order quantities in the newsvendor model under exponential demand

Halkos, George; Kevork, Ilias - Volkswirtschaftliche Fakultät, … - 2012

Three estimation policies for the optimal order quantity of the classical newsvendor model under exponential demand are evaluated in the current paper. According to the principle of the first estimation policy, the corresponding estimator is obtained replacing in the theoretical formula which...
