The paper considers a forest management problem, which consists of decisions on investment, silvicultural and harvesting activities for an existing forestland over a long time horizon, while guaranteeing sustainability, maximizing the expected profit, referring to ecological objectives and the public's acceptance of decisions. In order to solve this problem, several decision support systems and models were developed. Here, we present a fuzzy, dynamic and multi-objective model for optimal forest management, which determines the sequence of decisions that jointly maximizes economic, ecological and social objectives, respects prescribed constraints and imprecision, and takes the forest system from its existing state to the goal state. The idea of fuzzy analytic hierarchy process is introduced within a discrete dynamic programming process to evaluate the conflicting objectives.
