The Facility Location Problem in a Reverse Logistic Network: Weeenmodels Project in the City of Genoa

In this paper a multi-stage multi-commodity facility location problem for a reverse logistic network is proposed. In particular, this problem is applied to the city of Genoa, Italy, which is the test case for the Weeenmodels project, co-financed by the European Commission, started in 2013 and lasting until 2016. This project aims at defining and developing innovative logistic solutions for collection, reuse and recycle of waste deriving from electric and electronic equipment, according to the recent European Directive 2012/19/EU. For this problem, a MILP formulation is proposed in the paper. Some interesting results about the development of the waste collection system in the city of Genoa are presented and discussed.
