  Citation × Citation Citation Abstract Copy Title: Statistical comparison of methods used in harvesting work studies Author: Oregon State University. Forest Research Laboratory, Miller, Mark E., Hossain, Mohammad M., Olsen, Eldon D. Work-study guidelines were developed using field data from thinning sites in the Oregon Cascade Range. Regression of detailed time study and shift-level data predicted harvesting production rates. Statistical analysis showed the relative difference in the discriminating power between shift-level studies versus detailed time studies. Indicator variables tested if there were significant differences between harvesting treatments. Confidence intervals demonstrated the improved effect of longer study lengths for both shift-level and detailed time studies.

  Citation × Citation Citation Abstract Copy Title: Logging incentive systems Author: Oregon State University. Forest Research Laboratory, Olsen, Eldon D. The use of crew incentives in logging operations in the western United States is an effective way to reduce costs and provide attractive wages. However, such systems require a reliable method of setting the price, a good estimate of the daily costs of labor and equipment, and a method of tracking production output. The introduction of an incentive system requires a substantial initial investment of company managerial time as well as the goodwill and trust of workers. The cost and wage behaviors, as well as the advantages and disadvantages, of five incentive systems are described in this paper. Calculations for the systems are demonstrated. The principles described can be applied to cutting, hauling, yarding and loading, or road construction. They are applicable to the operations of independent contractors or large companies and to union or nonunion crews. Title: Logging incentive systems Author: Oregon State University.

Forest Research Laboratory The production rates and costs of harvesting smallwood were determined for a small yarder (Koller K-300) operating under variable conditions: the size of the crew, the addition of a skidder to swing logs from the landing, and the type of harvest method-employed, either conventional or hot thinning (simultaneous felling and yarding of whole trees). Regression equations are presented for the felling, yarding, swinging, and loading cycles of each harvest method.

  Citation × Citation Citation Abstract Copy Title: Optimal bucking : two trials with commercial OSU BUCK software Author: Pilkerton, Stephen J., Stringham, Bennett, Oregon State University. Forest Research Laboratory, Olsen, Eldon D. Trials to achieve optimal bucking were made with updated OSU-BUCK software in an eastern and a western Oregon location during the summers of 1993 and 1994. The commercial version of the software allows tagging of each log with bar-code identification numbers and therefore provides tracking from stump to customer. Data management is enhanced by automatic creation of input and output files in spreadsheet format. The software allows a choice of scaling rules, and accommodates multiple species while increasing measurement accuracy. The trials showed that, as with previous software, preferred-length requirements are a stumbling block to achieving the most effectiveness. Value and volume increases achieved with OSU-BUCK were moderate. Pairing a Log-Quality Technician with a faller appears to be a promising method for users of optimal-bucking software.
