Abstract(s)
A otimização de rotas de veículos têm-se revelado importante em diversas áreas, desde a recolha de resíduos à entrega de correio, por exemplo. Os vários estudos já realizados mostram que é possível melhorar sistemas já implantados, com recurso a diferentes algoritmos e métodos computacionais. A abordagem deste problema direcionado à recolha de resíduos urbanos já demonstrou serem possíveis poupanças significativas, tanto financeiramente como em redução de tempo por percurso.
Posto isto, surgiu a proposta da Câmara Municipal de Silves em otimizar o atual sistema de recolha de resíduos urbanos, tendo em conta os vários percursos estabelecidos no concelho.
Este relatório apresenta então o trabalho desenvolvido no âmbito da otimização de circuitos de recolha de resíduos, aplicado ao concelho de Silves.
Usou-se como ferramenta uma extensão do ArcGIS, designada Network Analyst. Foram obtidos circuitos para toda a área de estudo, sendo que o foco da otimização foram os circuitos de resíduos indiferenciados destinados a recolher contentores de superfície.
Foram modelados dois cenários que geraram diferentes percursos, com base em vários pressupostos inicialmente estabelecidos para a otimização. Ainda foi simulado um terceiro cenário que avaliava as consequências dum presumível aumento na quantidade de resíduos a recolher, de forma a perceber até que ponto o sistema otimizado seria resiliente à mudança.
The vehicle routing optimization has proven to be important in many areas, from waste collecting to mail delivery, for example. A couple of studies already carried out show that it is possible to improve already deployed systems, using different algorithms and computational methods. The approach to this problem, aimed to urban waste collection, has already shown that significant savings are possible, both financially and in reducing journey time. Hereupon, the proposal of Câmara Municipal de Silves arose to optimize the current urban waste collection system, considering the several routes established in the municipality. This exposition presents the work developed within the scope of the waste collecting routes optimization, applied to the municipality of Silves. An ArcGIS extension, called Network Analyst, was used as tool. Routes were obtained for the whole study area, with the focus on the optimization process being the undifferentiated waste routes which collect specifically surface containers. Based on several assumptions initially established for the optimization, two scenarios were modeled which generated different routes. A third scenario was also simulated to evaluate the consequences of a presumed increase in the amount of waste to be collected, in order to understand how resilient the optimized system would be to change.
