A Plate Stacking Method for Automatic Packing of Precut-Processed Lumber

Abstract

The precut-processed lumbers are carried from a precut factory to a construction site after cutting in a precut factory. To enhance the construction efficiency in the construction site, the precut-processed lumbers should sort in the order of the usage. On the other hand, for the efficiency of transportation, it is necessary to lower the height of the packaging lumber. In this research, therefore, we propose a heuristic method for stacking lumbers. In this method, we determine the position of lumbers without inclining while inserting supplement lumbers, according to the order of the usage of them.
