Bilge Atasoy of Delft University of Technology will present a seminar to the Management Science Department

Abstract: Waste collection is one of the challenging problems in urban areas and needs even more attention due to increased urbanization. Different developments are being carried out in order to improve the operations including decision support tools for routing of the vehicles, smart containers with sensors or the use of multiple transport modes in an integrated way. In this talk, three different case studies will be covered with the corresponding methodologies. First, a large scale waste collection problem is dealt with territory planning making use of clustering methods. Each cluster is then solved with an ALNS algorithm that takes into account multiple objective functions including the convenience to the users and drivers. Secondly, a smart waste collection system is considered where sensor information from the containers is used in different ways to decide on which containers to be collected including predictive methods. Finally, a two-echelon vehicle routing problem is presented where an integrated water- and land-based system is envisioned for waste collection. The methodologies under different case studies are benchmarked against real-life solutions and/or algorithms in the literature.
