This paper considers the situation of a retail store subject to inventory inaccuracies stemming from execution problems. We assume that inventory inaccuracies are introduced by misplacement type errors that occur within the store, i.e. the whole quantity of products that is ordered and received from the supplier is not available on shelf to satisfy(More)

A single-period, uncertain demand inventory model is analyzed under the assumption that the quantity ordered (produced) is a random variable. We first conduct a comprehensive analysis of the well known single period production/inventory model with random yield. Then, we extend some of the results existing in literature: our main contribution is to show that(More)

The inventory inaccuracy occurs when the inventory shown in the Information System is not in agreement with the actually available inventory.(More)
This paper is concerned with analysing and modelling the effects of judgmental adjustments to replenishment order quantities. Judgmentally adjusting replenishment quantities suggested by specialized (statistical) software packages is the norm in industry. Yet, to date, no studies have attempted to either analytically model this situation or practically(More)
One of the implicit assumptions considered in the majority of investigations performed in the area of inventory management is that the physical flow of products that passes through an inventory system as well as the associated information flow are free from defects, i.e. for a given type of product, the quantity received matches exactly the quantity ordered(More)
