Annual timber procurement planning with bucking decisions
The problem we consider is a practical multiple-period wood procurement planning problem in the Eastern Canadian context. The forest cut blocks are large and heterogeneous; they have different densities and the diameter of the trees varies. This is a difficult forest management problem because it integrates two related problems: the forest bucking problem with a cut-to-length (CTL) bucking syst...
متن کاملTemporal Decay in Timber Species Composition and Value in Amazonian Logging Concessions
Throughout human history, slow-renewal biological resource populations have been predictably overexploited, often to the point of economic extinction. We assess whether and how this has occurred with timber resources in the Brazilian Amazon. The asynchronous advance of industrial-scale logging frontiers has left regional-scale forest landscapes with varying histories of logging. Initial harvest...
متن کاملContributions of community and individual small-scale logging to sustainable timber management in Cameroon
In Cameroon, sustainable timber management relies on the model of large logging concession. However, over the past fifteen years, small-scale logging has become a common activity, with two different forms. First, the creation of community forests in the late 1990s allowed village associations to legally harvest, process and trade timber, almost always with the support of external actors such as...
متن کاملEstablishing Workload Manipulations Utilizing a Simulated Environment
Research seeking to improve the measurement of workload requires the use of established task load manipulations to impose varying levels of demand on human operators. The present study sought to establish task load manipulations for research utilizing realistically complex task environments that elicit distinct levels of workload (i.e. low, medium, and high). A repeated measures design was used...
متن کاملRelationship between workload and mind-wandering in simulated driving
Mental workload and mind-wandering are highly related to driving safety. This study investigated the relationship between mental workload and mind-wandering while driving. Participants (N = 40) were asked to perform a car following task in driving simulator, and report whether they had experienced mind-wandering upon hearing a tone. After driving, participants reported their workload using the ...
