Modelo Integrado para Colheita Florestal e Planejamento Viário

Abstract

The correct modeling of forestry problems is crucial for obtaining applicable solutions. This work, part of a broader research in forest harvest optimization, presents the process of creating an integrated model for forest harvesting and road planning using Mixed Integer Linear Programming. The study focuses on integrating harvest scheduling and sequencing with the construction and maintenance of access roads. The main objective is to improve forest harvesting efficiency, aiming to maximize profit, meet periodic demand, and comply with environmental constraints. To this end, the model addresses the formation of harvest blocks, the logistics of trips required for each plot, and the management of road infrastructure, including the costs of opening and maintaining roads. The constraints detail harvest planning, the use of the road network, and vehicle flow, culminating in an objective function that seeks to optimize these processes. It is emphasized that the applicability of mathematical solutions depends on the accuracy of modeling and the availability of field data to ensure the model’s feasibility.
