While the net present value (NPV) approach is widely accepted as the right framework for studying production and inventory control systems, average cost (AC) models are more widely used. For the well known EOQ model it can be veri_ed that (under certain conditions) the AC approach gives near...

An important difference between both manufacturing and wholesaling vs. retail is the information available concerning inventory. Typically, far less information characterizes retail. Here, an extreme environment of information shortfall is examined. The environment is technically termed...

In this paper, we assess the need for logistics information and knowledge management in humanitarian aid organizations. To do so, we combine literature sources with an extensive case study that we conducted at Médecins sans Frontières–Holland, which is following a trajectory to improve...

In this paper we investigate recent initiatives with respect to extended producer responsibility in the aviation sector. We compare those with the existing practices in the automobile sector and the emerging regulations in the shipping sector. We describe the challenges and the lessons to be...

The Net Present Value (NPV) approach is considered to be the right approach to study inventory and production systems. But, approximate average cost (AC) approach is widely used in both practice and theory. However, the opportunity cost interpretation of AC framework is not that straightforward...

In this paper we extend the PUCH and PULL control strategies defined in Van der Laan et al. (1995) to evaluate empirically the effect of lead-time duration and lead-time variability on total expected costs in production/inventory systems with remanufacturing
