Um modelo otimizador para organização dos compartimentos de exploração em floresta tropical

Abstract: Existe a necessidade de garantia de um fluxo constante de madeira com potencial comercial para a viabilidade da pequena propriedade, porém nem sempre isto é possível, pelo fato de os talhões serem pequenos e, principalmente, a distribuição das espécies de interesse na floresta nativa ser irregular, por serem os ecossistemas heterogêneos e pela variedade de tipologias florestais que formam um complexo mosaico. Este trabalho teve como finalidade principal apresentar um modelo matemático que auxilie no planejamen… Show more

“…The GPS technology and remote sensing are used to control and evaluate field work or mitigate forest damages (Marvin et al 2016). Due to the high operational complexity and costs of selective logging, mathematical programming models are effetive aids in planning and executing logging routines (Braz et al 2004;Gomide et al 2010, Fernandes et al 2013, but have yet to be implemented as widespread optimization tools in selective logging enterprises in the Brazilian Amazon. Thus, the objective of this study was to develop integer linear programming (ILP) models to minimize the distance between harvested trees and the planned log landings, integrating the BDq method, economical aspects, adjacency constraints and wood production parameters.…”

“…Para seu controle tem-se estimulado a adoção de tecnologias adequadas, como aquelas que são aplicadas em áreas de manejo florestal sustentável (Leite & Resende, 2010). A viabilidade do manejo sustentável está em garantir um fluxo constante de madeira com potencial comercial (Braz et al, 2004), sem interromper de maneira irreversível os processos de sustentação do ecossistema (Higman et al, 2015).…”

“…Therefore, to address such problems, researchers used operational research methods. Several examples of this method can be found in existing studies on the planning of forest production operations (Contreras and Chung, 2007;Karlsson et al, 2004;Murray and Snyder, 2000;Shahi and Pulkki, 2013;Søvde et al, 2013) but also related to issues of traditional communities, non-timber forest products and forest fragmentation (Arima et al, 2008(Arima et al, , 2005Braz et al, 2004;Kelley et al, 2013;Lopes, 2018;Munaretti, 2016;Walker et al, 2013). More specifically, Silva et al (2018a) presented a theoretical study that discussed the relationship between forest road infrastructures, storage yards, and skid trails, and reported the need for more detailed analysis to be planned.…”
