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 piece and data representing geometric and grade characteristics. A subset of parts characterized by predetermined grade value and associated with a predetermined group of dimension values is defined, as well as an arrangement of subdivided 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 from 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 yield value for the arrangement is estimated, and the optimization sequence repeated for new arrangements to estimate basic yield values, to select the best arrangement.
