SDP diameter is 30cm and SDP are utilizing in Iran and world by wood product industries, because large diameter timber decreased. SDP had not the best application because Eastern Azarbayjan province factory situation are unsuited. Since the research was accomplished on the populus nigra, particleboard and plywood industries of Eastern Azarbayjan province. Therefore , the basic of questions as follow: will SDP of application in particleboard and plywood industries economical grading on the basis of account criterions? Since the research methodologies are analytic and approximate. Engineering estimate, account analysis, cost regression analysis are used by research. The result of: Account criterions were showed that increasing SDP diameter more production rate and safety limits is reliable. If the main purpose is core production, plywood industries must utilize little SDP.SDP economic grading are desirability arrangement as follow;No.1; 25.01 _ 30 cm diameterNo.2; 20.01 _ 25 cm diameterNo.4; 15 cm diameterNo.3; 15.01 _ 20 cm diameterNo.4; 15 cm diameterNo.3; 15.01 _ 20 cm diameter No.4; 15 cm diameterlittle poplar SDT will profit if native technology as example; small move product system that has enough ability and suitable efficiency and product rate are propagate.
