Forest Monitoring and Harvesting Policies [PDF]
Applied Mathematics and Computation, 1983 This paper considers the problem of what information must be measured in a forest management model in order to generate optimal feedback harvesting policies. Together with this question, the paper also addresses the issue of how LP-based models can be embedded within the dynamic programming framework, so that feedback rather than open-loop decisions ...
