Incorporating financial analysis into timber harvest scheduling models
… and adapted to a forest products firm’s timber harvest scheduling model in an attempt to increase its net present value of harvest returns, using alternative harvest criteria. The firm’s original harvest scheduling model was used as a control model for the study. A net present value financial …

Maximizing wildlife benefits through hardwood timber harvest scheduling
A computerized system for planning timber harvest to maximize habitat quality over time for a specified group of wildlife species was developed for upland oak forests of the Eastern United States. This system, called WILDWOOD for WILDiife/WOOD optimization system, is designed to run on a …

Special versus standard algorithms for large-scale harvest scheduling problems
… the design of algorithms for solving large-scale harvest scheduling problems. We discover that the harvest scheduling problem involving area constraints possesses a network structure. In Model I-Form 1, the network constraints form a separable block diagonal structure, which permits one to solve …

Analysis of timber harvest scheduling under alternative levels of land aggregation: an application to a hypothetical Mexican forest ownership
… and area volume constraints for timber harvest scheduling. Then, the present value-maximizing timber harvest schedules for each level of land organization was found by using LP Model 1 formulations. Results showed that timber harvesting net benefits varied between 1.3% and 7.0% across …

A spatial stochastic programming model for timber and core area management under risk of stand-replacing fire
Forest harvest scheduling has been modeled using deterministic and stochastic programming models. Past models seldom address explicit spatial forest management concerns under the influence of natural disturbances. In this research study, we employ multistage full recourse stochastic programming …

Development of a prototype model for optimizing silvicultural investment on a diverse forest ownership in central Maine
… Maine. The model was based on the Model I harvest scheduling formulation of Johnson and Scheurman (1977). The linear programming based model incorporated a choice of three objective functions (cost minimization, present net worth maximization, and woodflow maximization) subject to limited …

Modeling, Analysis, and Exact Algorithms for Some Biomass Logistics Supply Chain Design and Routing Problems
… encountered in the Southeast, and a corn stover harvest scheduling problem faced in the Midwest Unites States, both pertaining to the production of cellulosic ethanol. The main contributions of our work have been in introducing new problems to the literature that lie at the interface of the …
