An efficient specification and solution method of the even-aged rotation and thinning problem

Creator:: Paredes-Veloso, Gonzalo L.
Abstract:: The problem of determining an optimal sequence of decisions in even-aged stand management is analyzed and solved with an alternative to the traditional dynamic programming network. The new method is derived independently from two different approaches to the problem: Network optimization and generalized LaGrange multipliers. Both derivations are presented. It...

A stochastic analysis of erosion and economic impacts associated with timber harvests and forest roads

Creator:: McNutt, James Allen
Abstract:: A complex and sometimes serious problem facing modern day forest managers is that of estimating and analyzing potential on-site impacts which result from forest activities. A major type of adverse impact is man-Initiated forest erosion. This consequence can be substantially magnified when forest harvest and road activities are implemented in...

The potential contribution of a diameter class matrix model to predict growth of mixed tropical forests

Creator:: Ebaa-Atyi, Richard
Abstract:: The study presents two main parts: first, a review of tropical silviculture and forest management systems and, second, the investigation of a growth and yield model which has some potential for application in the tropical region. The presentation of tropical silviculture includes: (1) an overview of the biological characteristics of...

A comparison of prediction models for cover type transitions and their effects on harvest schedules in coastal Oregon

Creator:: Eng, Helge
Abstract:: There is considerable uncertainty associated with stand establishment in coastal Oregon. Several species can gain control of the site depending on stand conditions as well as management practices. In this study, three cover type transition models were developed using data from the Siuslaw National Forest to predict stand establishment patterns...

Optimizing the primary forest products supply chain : a multi-objective heuristic approach

Creator:: Hamann, Jeff D.
Abstract:: This thesis is a collection of four submitted manuscripts that present methods to assist forest ecosystem service managers wanting to develop operational sampling, monitoring, and production plans for a set of specific quantifiable ecosystem services, which are formulated as a series of general multi-objective optimization problems. The problems are solved...

Trees : timber resource economic estimation system

Creator:: Tedder, Philip L., Schmidt, James S., Gourley, Jonna, and Oregon State University. Forest Research Laboratory
Abstract:: Volume I: TREES (Timber Resource Economic Estimation System), a forest management and harvest scheduling model, is comprehensively described in the first of a four-volume series. Even- or uneven-aged forest inventories form basic resource units (BRUs), entered by age class or size and diameter classes; stocking level; and management intensity. Management...

Model III : a sequential approach to joint optimization of the stand treatment and forest level harvest scheduling problem

Creator:: Barber, Richard L.
Abstract:: Harvest scheduling and stand level optimization have generally been regarded as separable problems. Some studies have attempted to jointly optimize a wide range of stand treatments and a forest wide harvest schedule using combinations of mathematical programming techniques. The mathematical programming forest level techniques presume perfect information on production, costs...

Economic analysis of integrating spatial concerns into harvest scheduling

Creator:: Yoshimoto, Atsushi
Abstract:: An analytical algorithm to formulate a sparser set of adjacency constraints than the conventional algorithm is proposed. Utilizing matrix algebra applied to an adjacency matrix, constraints are systematically and efficiently derived by the proposed algorithm. The proposed algorithm is proved to provide a true set of adjacency constraints in the...

Spatially explicit inter-temporal forest management decision under the risk of fire

Creator:: Konoshima, Masashi
Abstract:: This paper presents a framework for analyzing efficient spatial allocation of forest management efforts - fuel treatment and harvest - under the risk of fire. The framework integrates a fire behavior model and a spatially-explicit stochastic dynamic optimization model. I investigate the effects of spatial interaction across plots during forest...
