We study a single product two-period production/inventory model, in which the demands at each period are independent random variables. To optimally satisfy these random demands, quantities can be produced at the beginning of each period using slow or fast production mode, under capacity...

Research on sustainability performance has considerably enriched operations management literature in recent years. However, work with quantitative models is still scarce. This paper contributes by revisiting classical inventory methods taking sustainability concerns into account. We believe that...

In this paper, we consider a two-stage supply contract model for advanced reservation of capacity, with payback option at the beginning of the selling season. Between the two decision stages, external information is collected that serves to update the demand forecast and permits to adjust the...

A proposed single-product, stochastic, two-period inventory control model combines demand forecast updating with the flexibility of two supply sources. Demand is modeled by two independent, random variables over a two-period selling season. At the beginning of the first period, two quantities...

We consider a finite-horizon, single-stage, single-product periodic review store inventory in which inventory records are inaccurate. We assume that inventory inaccuracies are introduced by theft type errors that arise within the store. We propose a comparison between three approaches based on...

This paper examines a Newsvendor framework in which a wholesaler who sells products to retailers is subject to inaccuracies in inventory data. The wholesaler's decision regarding the management of his warehouse inventory is based on inventory data recorded in the information system. We assume...

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...

This paper investigates the impact of product perishability on the known (r,Q) inventory review policy and the benefits of using Time Temperature integrator technology (TTI) on inventory management. We first formulate an (r,Q) inventory model for perishables having a fixed lifetime. Then, we...
