METHOD OF OPTIMIZING A LAYOUT OF SELECTED PARTS TO BE CUT

摘要

A method of optimizing a layout of selected parts to be cut from a piece of wood uses data representing geometric and defect-related characteristics pie ce and data representing geometric and grade characteristics. A subset of parts characterized by predetermined grade value and associated with a predetermin ed group of dimension values is defined, as well as an arrangement of subdivide d piece surface sections to be obtained through primary cutting operation. Subsections included in each section are defined according to geometric and defect-related characteristics, and a plurality of arrangements selected fro m the subset of parts to be obtained through secondary cutting operation, are defined. Yield values associated with the arrangements are estimated and compared to select the arrangement having a highest yield value. A basic yie ld value for the arrangement is estimated, and the optimization sequence repeat ed for new arrangements to estimate basic yield values, to select the best arrangement.
