Use of the Dominance Concept for Matching Raw Material Grades of Douglas-fir to Lumber Production Objectives
Keywords:Product line planning, value added, technology assessment, multiple objectives, product policy
AbstractThe concept of dominance, adopted from game theory, was applied to the problem of determining the most feasible Douglas-fir log grades for producing a given lumber product mix. Three sets of multiple objectives, representing three different broad categories of mills, were analyzed to assess how changes in the primary product mix affected the log buying and trading decisions. The mill categories examined were integrated mills producing both structural and nonstructural lumber, cutting mills producing nonstructural specialty lumber, and dimension mills producing structural lumber. In general, peeler log grades were most suitable for nonstructural lumber, while sawlogs were most suitable for structural lumber. Feasible log grades for the integrated mills included both peeler logs and sawlogs, but were predominantly second growth. Repeating the analyses with 1960 data indicated little change in log grade selections over time.
