Optimizing reverse logistics scenarios: a cost-benefit study using IBM´s WIT tool

This paper presents an overview of a conceptual study designed to examine the costs and benefits of product end-of-life disposition decisions for used electronics equipment. The study utilizes a reverse logistics supply chain model to examine these decisions. The model was created using the IBM supply chain optimization tool known as WIT (Watson Implosion Technology) developed by IBM´s TJ Watson Research Center. The WIT tool automates the decision making process used to determine the optimal mix of equipment that should be refurbished for resale versus dismantled for parts thereby greatly improving the information available for determining end of life disposition solutions.
