Abstract
The paper presents an optimisation method for selective waste collection
services in university campuses in Bucharest. Based on geographic information
system (GIS) procedures and algorithms, an optimisation method for selective
waste collection services is developed. The area of Bucharest City, the road
network, the location of the selective waste collection points in the main
university campuses and the location of the collection station are organized in
GIS format. Complex geodatabase structures that allow solving the large scale
selective waste collection problem are designed. The routing solution that
minimises the total travel time is determined taking into consideration the local
road network properties and the location of the collection station for each
category of waste (glass, paper and plastic). The methodology is applied for the
main University Campuses in Bucharest. The map with the routing solution, the
required number of vehicles and the schedule for each category of waste and for
each vehicle are obtained. The developed method provides informational and
technological support for public authorities and selective waste collection
operators.
Keywords: selective waste collection, optimisation, vehicle routing, scheduling,
geographic information system.
1 Introduction
The problem presented in this paper is from a study carried out for the selective
waste collection management system in university campuses in Bucharest. With
over 250000 students, Bucharest is the greatest national university centre of
Romania. There are over 15 important universities with academic, administrative
and residential activities organized in campuses spread out in different areas of
the city. The campuses have different organization systems, according with the
structure, location, tradition and evolution of each university. Due to the large
Keywords
selective waste collection, optimisation, vehicle routing, scheduling,
geographic information system.
