Este trabalho desenvolve um modelo, baseado em técnicas exploratórias de dados e de estatística multivariada, que permite identificar as variáveis mais relevantes associadas ao sucesso da implementação de programas de reciclagem de resíduos de construção e demolição (RCD) nos municípios brasileiros. Os resultados da pesquisa mostraram que existem diferenças marcantes entre as cidades que implantaram programas de reciclagem de RCD e aquelas que não implantaram. As variáveis mais significativas encontradas foram: percentual de funcionários de nível médio que trabalham na prefeitura, renda média anual do município, percentual de domicílios com água, existência de programas de coleta seletiva de lixo, programas de incentivo para geração de trabalho e renda e existência de áreas de recepção de entulhos, a maioria relacionadas à gestão municipal.
ABSTRACT. Logistics hubs affect the distribution patterns in transportation networks since they are flowconcentrating structures. Indeed, the efficient moving of goods throughout supply chains depends on the design of such networks. This paper presents a literature review on the logistics hub location problem, providing an outline of modeling approaches, solving techniques, and their applicability to such context. Two categories of models were identified. While multi-criteria models may seem best suited to find optimal locations, they do not allow an assessment of the impact of new hubs on goods flow and on the transportation network. On the other hand, single-criterion models, which provide location and flow allocation information, adopt network simplifications that hinder an accurate representation of the relationship between origins, destinations, and hubs. In view of these limitations we propose future research directions for addressing real challenges of logistics hubs location regarding transportation networks design.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
