In a Two-Level Reverse Distribution Network, products are returned from customers to manufacturers through collection and refurbishing sites. The costs of the reverse chain often overtake the costs of the forward chain by many times. With some known algorithms for the problem as reference, we propose a hybrid memetic algorithm that uses linear programming and a heuristic for defining routes. Mo...

Supply chain network design (SCND) is a challenging strategic issue for any company since it involves long-term decisions and high capital investment (see e.g. (Owen & Daskin, 1998) and (Melo, et al., 2009) for an overview of network design and facility location literature).

Recognition of clinical syndromes in returned travelers is an important part of providing care to international travelers. The first step is to take a history with attention to pre-travel preventive measures, the patient's itinerary, and potential exposure to infectious agents. The patient should then be examined to document physical signs, such as fever, rash, or hepatosplenomegaly, and to hav...

The global demand for consumer electronic products has been phenomenal in the last two decades. The negative environmental effects of the growing consumption of electronic hardware are most visible in the end-of-life (EOL) stage. Remanufacturing is a viable option in electronic waste management as it reduces e waste generation and increases reuse of equipment and components. Inventory control i...
