Optimization of waste collection through the sequencing of micro-routes and transfer station convenience analysis: an Argentinian case study

Municipal solid waste management is a paramount activity in modern cities due to the environmental, social and economic problems that can arise when mishandled. In this work, the sequencing of micro-routes in the Argentine city of Bahía Blanca is addressed, which is modeled as a vehicle routing problem with travel time limit and the vehicle's capacity. Particularly, we propose two mathematical formulations based on mixed-integer programming and we solve a set of instances of the city of Bahía Bl...
