This work addresses a forest management problem for timber production while considering fire risks. It employs a simulation-optimization approach, refining decisions based on fire spread simulations. The goal is to select one management plan per stand while meeting constraints, including ecosystem service limits, to maximize net present value.
Fire travel times depend on fuel, wind, and slope, with fire spread simulated from ignition points. Fire paths exceeding a spread rate threshold are identified, adding constraints to prevent selecting their associated plans together.
Computational experiments in a Portuguese forest compute trade-offs between economic returns and fire risk. The method identifies fire breaks under strict fire constraints and assesses the influence of surrounding forests and ecosystem service limits.
