the determination of effective indicators in order to decide on the location of industrial units with the aim of optimizing the use of raw material, reduce costs and waste and marketing of products is very important. determining the effective indicators in optimal choice for seating block board unites (with use the back of scrap plywood, twigs little low diameter wood’s) in country was target o...

Dynamic game theory is applied to analyze the timber market in northern Iran as a duopsony. The Nash equilibrium and the dynamic properties of the system based on marginal adjustments are determined. When timber is sold, the different mills use mixed strategies to give sealed bids. It is found that the decision probability combination of the different mills follow a special form of attractor an...

Sawmills require specific information on the volume, the number and the diameter classes of different types of log assortments that could potentially be cut from a stand which the mill intends to tender for or harvest. Knowledge of the consequences of adopting a particular cross-cutting strategy would also enable mills to identify the optimum combination of products to be harvested from a stand...

At present, mills producing structural timber generally undertake strength grading at the end of the production process, i.e., after buying the material and sawing it into timber which is then dried. This means that any variation in wood stiffness between forest stands and between trees is unknown and unaccounted for until the end of the manufacturing process. Portable stress-wavebased tools pr...

Construction wastes have become the major source of solid wastes in Hong Kong. Thousands of tonnes of solid wastes are produced every year from construction and demolition activities. Increasing generation of these wastes has caused significant impacts on the environment and aroused growing public concerns. Therefore, the minimization of construction wastes has become a pressing issue. This pap...

It seems to the Inquiry that for much of its history the native forest sawn timber industry has been in disequilibrium with the supply of its raw material. In most years there seem to have been too many mills for the timber on offer. Milling capacity has almost always been greater than the supply of logs to the mills. Individual mills dependent on native forest, and the groups of such mills tha...

Over the last three decades the exportation rate of raw sawlogs from Illinois to neighboring states for processing has nearly doubled. While the exportation of sawlogs has adverse impacts on the Illinois wood products manufacturing sector and local forest landowners, little research has been conducted to understand how the spatial arrangement of timber mills affects sawlog exportation. This res...

The aim of this study was to determine the optimal cutting cycle in an uneven-aged beech forest in the North of Iran. First of all, a logistic growth model was determined for an uneven aged forest. Then, the stumpage price was predicted via an autoregressive model. The average stumpage price of beech was derived from actual timber, round wood, fire and pulpwood prices at road side minus the var...

The activity of the Russian timber processing industry is inextricably linked to constant generation wood waste. paper considers types waste as well possibility their integrated use in conditions plant. We present results experiments on production fibre boards with addition prepared waste: bark, sawmill waste, format-cutting trapped and hardwood determine optimum percentage studied total mass.
