ORLANDO LEAL, Robert  and  AMILCAR LOPEZ, César. Methodology for logistic planning of forest roads for harvesting Eucalyptus globulus Labill. using optimization tools. Colomb. for. [online]. 2011, vol.14, n.1, pp.51-67. ISSN 0120-0739.

Using an uncapacitated and nondirected network model, we propose a methodology for the preliminary design of second order forests roads to extract products from Eucalyptus globulus plantations using an aerial cable system to minimize road network construction costs. The model takes into account topographical conditions and road construction costs related to the terrain slope. In order to solve the problem the Dijstrak algorithm was used, in which the minimum cost of the shortest paths that connect all the stockyards are defined. In addition, the Kruskal algorithm was used to obtain the minimum spanning tree. Finally, the network was connected to an open road for the timber to be taken to consumption centers. In order to develop the algorithms mentioned above, an application on Matlab was designed, which gave an easier handling of the cartography data obtained from these algorithms.
