The classical Economic Order Quantity (EPQ) models consider that the production rate is fixed and constant. But in many manufacturing and production processes the production rate is a function of stock on hand. For this sort of situations we develop and analyze an EPQ model with the assumption that the production rate is a function of the on-hand inventory and demand is a function of selling pr...

Women with bulimia nervosa and controls were compared on their short-form Eysenck Personality Questionnaire-Revised (EPQ-R) scores. It was found that women with bulimia nervosa scored significantly higher on neuroticism and significantly lower on the Lie Scale. This latter result could not be explained by differentiation of the Lie Scale into its two components, social desirability and ‘faking ...

The EOQ and EPQ models with linear and fixed backorder costs are newly analyzed and all formulae are proven using only algebra. Two cases are identified, where backorders should and should not be allowed. The results are shown to include several known special cases. r 2004 Elsevier B.V. All rights reserved.

OBJECTIVE Disgust is a basic emotion associated with feelings of revulsion and withdrawal behaviors from dangerous situations. The aim of this study was to examine the psychometric properties of the Disgust Scale--Revised (DS-R), a tool designed to measure individuals' responses to various disgust-provoking situations, among Korean populations. METHODS A sample of 1117 healthy volunteers comp...

The algebraic arithmetic-geometric mean inequality method (the algebraic AGM method) is used to derive the optimal lot size and the optimal backorders level for the EOQ and EPQ models with backorders and defective items introduced by [6]. The method is easy to derive both the optimal lot size and optimal backorders level without derivatives. AMS Subject Classification: 90B05
