Development of a 3d Log Sawing Optimization System for Small Sawmills in Central Appalachia, Us
A 3D log sawing optimization system was developed to perform log generation, opening face determination, sawing simulation, and lumber grading using 3Dmodeling techniques. Heuristic and dynamic programming algorithms were used to determine opening face and grade sawing optimization. Positions and shapes of internal log defects were predicted using a model developed by the USDA Forest Service. L...
متن کاملA Three-dimensional Optimal Sawing System for Small Sawmills in Central Appalachia
—A three-dimensional (3D) log sawing optimization system was developed to perform 3D log generation, opening face determination, sawing simulation, and lumber grading. Superfi cial characteristics of logs such as length, large-end and small-end diameters, and external defects were collected from local sawmills. Internal log defect positions and shapes were predicted using a USDA Forest Service ...
متن کاملSimulation of Hardwood Log Sawing
Preface Abstract Mathematical modeling computer programs for several hardwood sawing systems have been developed and are described. One has judgment capabilities. Several of the subroutines are common to all of the models. These models are the basis for further research which examines the question of best-grade sawing method in terms of lumber value yield. This Research Paper is one in a series...
متن کاملEffect of Curve Sawing on Lumber Recovery and Warp of Short Cherry Logs Containing Sweep
—It has been estimated that approximately one-third of hardwood sawlogs have a significant amount of sweep and that 7 to nearly 40 percent of the yield is lost from logs that have greater than 1 inch of sweep. While decreased yield is important, for hardwood logs the loss of lumber value is likely more significant. A method that produced lumber while accounting for log curvature (sweep) would a...
متن کاملSAWing on Symmetry
In this paper we investigate the behavior of mutation-based evolutionary algorithms on highly symmetric binary constraint satisfaction problems. With empirical methods we study why and when these algorithms perform better under the stepwise adaptive weighting of penalties (SAWing) than under the standard penalty function. We observe that SAWing has little effect when the local optima of the sym...
