YIELDS OF RUBBERWOOD SAWN TIMBER

Abstract

Yields of sawn timber from rubber trees were studied in a processing mill. Significant differences were detected when yields were categorized by diameters of logs and sizes of sawn timber produced. A relative frequency weighted approach was proposed as a better estimation technique to assess the average yields. Yields categorized by log diameters and sawn timber sizes, and weighted with relative frequencies would be a more accurate and useful input for planning and controlling of the sawmilling operation.
