Arc Routing Using a Geographic Information System: Application in Recyclable Materials Selective Collection
This study aims to utilize a Geographic Information System (GIS) as an arc routing tool (door-to-door model) for a recyclable materials selective collection program. The investigation uses real data from material gatherers association in the city of Itajubá, Minas Gerais, Brazil. The research method is modeling and simulation. TransCAD 4.8 is used because it possesses an arc routing routine. Scenarios were simulated in which the most efficient routes were sought (shortest and fastest) in comparison with the associations real trajectories, which were collected in the field of study by means of a Global Positioning System (GPS) device. The results obtained, when compared to the current system, showed better performance (distance, time and volume of material). Thus, by using a GIS, it can be said the main logistics problems in the gatherers association are direct consequences of poor structuring.
