| dc.description.abstract | The harvest scheduling problem customarily known as Model II is reformulated as a control theory problem, and two ways of solving it using the numerical methods of linear programming are discussed. Viewing the problem in this way offers many insights and makes extensions to the basic problem relatively easy to handle. Extensions discussed include the risk of catastrophic loss through fire including the possibility of partial salvage of volumes burnt; the problem of a changing land base; the imposition of area constraints on standing forest; the inclusion of multiple timber types; and the problem of accessibility. The last two extensions are discussed in the context of the presence of the risk of fire. The mathematical relationship between the standard Model II linear program, and the control theory formulation is discussed and the numerical efficiency of the various methods is examined for simple problems. | en |
