Design and Results of a Study Concerning Felling and Bucking Errors Item Info

Felling and bucking errors associated with timber harvesting operations have resulted in substantial dollar losses to logging operators. This thesis describes an attempt to quantify these losses and the effect of training upon the reduction of these losses. Three manuscripts are presented, each dealing with one aspect of the research. The first manuscript describes the computer model used to analyze the data and its structure on the University of Idaho’s IBM 1431 computer. The original model, developed by the U.S.F.S., is known as “Felling & Bucking Activity (FAB)”. This manuscript provides data input procedures and explains model output. A sample terminal session, using existing data files, is described in detail. The second manuscript quantifies the losses incurred in this study and the results of logger training upon reducing these losses. The University of Idaho’s Experimental Forest Logging Crew was studied and losses associated with felling and bucking errors “before training” and “after training” are presented. The third manuscript describes study design and sampling procedures used in this study. These procedures are contrasted to the “normal” approach used in felling and was statistically designed; a unique approach used in felling and bucking studies. Analysis of the results reveals that the “normal “ approach may not be accurate enough to base predictions of felling and bucking loss upon.
