The use of relaxation to solve harvest scheduling problems with flow, wildlife habitat, and adjacency constraints

Creator:

Torres-Rojo, Juan Manuel

Abstract:

Lagrangean relaxation is presented as a solution technique to solve flow constrained area-based harvest scheduling problems. The best set of multipliers in the Lagrangean approach is obtained through the subgradient method. Guidelines to set some parameters to compute the step size in the subgradient algorithm are provided. An additional procedure...

An economic analysis of hardwood treatment in loblolly pine plantations--a whole rotation dynamic programming approach

Creator:

Valsta, Lauri

Abstract:

To accomplish an economic evaluation of vegetation management in loblolly pine (Pinus taeda L.) at regeneration and a subsequent release time, two existing growth models were linked together in a dynamic programming analysis. The first model (Burkhart and Sprinz, 1984) provides a projection of stands regenerated with varying hardwood components...
