Das Bestandsmanagement von Ersatzteilen stellt Hersteller langlebiger Industrie- und Konsumgüter insbesondere in der Nachserienphase vor große Herausforderungen, da nach Abschluss der Serienproduktion die zur einer effizienten Bedarfsbefriedigung notwendige Flexibilität nur noch in...

The efficient supply of spare parts is of prime concern for OEMs. Next to the traditional spare parts sources in form of final order and remanufacturing, the option to buy back broken products prevents the OEM from fulfilling his spare parts availability obligation in the end-of-life phase and...

This article analyzes a discrete time lost sales inventory system with partially observed demand and unobserved shrinkages which happen both before and after the demand realization. When the demand exceeds the remaining inventory, the unmet demand is lost and unobserved. This problem in general...

In reverse logistics networks, products (e.g., bottles or containers) have to be transported from a depot to customer locations and, after use, from customer locations back to the depot. In order to operate economically beneficial, companies prefer a simultaneous delivery and pick-up service....

We present a new model formulation for a multi-product lot-sizing problem with product returns and remanufacturing subject to a capacity constraint. The given external demand of the products has to be satisfied by remanufactured or newly produced goods. The objective is to determine a feasible...

We investigate firms' re-manufacturing strategies in the case of a Cournot duopoly. On one hand, re-manufactured products cannibalize sales of new products by the same firm and hurt its profits. On the other, re-manufacturing can be a profitable marketing strategy to target different customer...

Inventory policies for joint remanufacturing and manufacturing have recently received muchattention. Most efforts, though, were related to (optimal) policy structures and numericaloptimization, rather than closed form expressions for calculating near optimal policy parameters.The focus of this...

Most recommerce providers have moved to a quality-dependent process for the acquisition of used products. They acquire the products via websites at which product holders submit upfront quality statements and receive quality-dependent acquisition prices for their used devices. Motivated by this...

Sustainability has become a major issue in most economies, causing many leading companies to focus on product recovery and reverse logistics. This research is focused on product recovery, and in particular on production control and inventory management in the remanufacturing context. We study a...
