Closed loop supply chains aim at closing material flows thereby limiting emission and residual waste, but also providing customer service at low cost. We study 'traditional' and 'new' design principles known in the literature. It appears that setting up closed loop supply chains requires some additional design principles because of sustainability requirements. At the same time however, we see that traditional principles also apply. Subsequently we look at a business situation at Honeywell. Here, only a subset of the relevant design principles is applied. The apparent low status of reverse logistics may provide an explanation for this. To some extent, the same mistakes are made again as were 20 years ago in, for instance, inbound logistics. Thus, obvious improvements can be made by applying traditional principles. Also new principles, which require a life cycle driven approach, need to be applied. This can be supported by advanced management tools such as LCA and LCC. http://repub.eur.nl/res/pub/1697/ 2001-11-01T00:00:00Z Closed Loop Supply Chains include operations for physical collection of end-of-use products, selection based on their configuration and/or condition and decision making for reuse, remanufacturing or recycling. Uncertainty factors regarding the time, place of origin, and status of returns introduce many difficulties in planning these operations. With the aim to minimize such problems, this paper presents an architecture for virtual reverse logistics networks and an implementation for end-of-use PCs. The virtual reverse logistics network for PCs relies on E-commerce and WWW technologies for remote monitoring and benchmarking, instead of physical transportation and inspection. A configuration monitoring and benchmarking agent screens the computer that is about to enter the end-of-use stream and registers the data in the system’s databases. The virtual reverse logistics network regards all incoming PCs as submitted offers. Also, users or agents may explicitly register requests for PCs or modules. Offers are matched to requests with a decision support system to provide recommendations for reuse, remanufacturing or recycling of end-of-use PCs. An electronic marketplace matches requests and offers. The proposed architecture diminishes the uncertainty factors and provides us with an understanding on what is missing and it is likely to have a positive impact to the development of virtual reverse logistics networks for computers and other equipment with embedded logic. http://repub.eur.nl/res/pub/1662/ 2001-02-19T00:00:00Z Reverse logistics, that is, all operations related to the reuse of used products, excess inventory and packaging materials, gain increasing attention globally both for their promising financial potentials, the sustainable growth alternative they offer and the environmental positive impact they have. In this paper, we introduce reverse logistics and we explain how the adoption of e-commerce provides new possibilities to existing business models and what are the new e-business models in reverse logistics that have emerged. We compare these three new e-business models, namely, returns aggregators, specialty locators and integrated solution providers on a number of aspects and identify keys for their competitive advantage. Finally, we discuss conceptual and actual opportunities for these e-business models to thrive and advance and present some e-commerce tools that are being developed with the aim to address the distributed, dynamic and knowledge-intensive aspects of applications that contribute to the advancement of e-businesses in the field of reverse logistics. http://repub.eur.nl/res/pub/729/ 1999-12-22T00:00:00Z In this paper we consider the role Electronic Commerce plays and can play for Reverse Logistics. After short introductions to electronic commerce and reverse logistics, we give an overview of existing internet sites for reverse logistics. These sites can be classified as electronic markets, supply of used parts and complete reverse logistic solutions. Finally we draw some lines to the future.
