Research on the Quantitative Analysis of the Timber Supply System for the Effective Utilization of Available Forest Resources

(1)由于日元汇率的上升，美国和加拿大木材的进口在日本市场的份额显著增加。另一方面，国外原木锯厂的规模比以前更大，更合理。(2)由于木匠的短缺，房屋木材的预切加工增加，木材的分配变得简单，如大的房屋制造商直接从锯木厂购买，而不区分国内或国外。(3)尽管有大量可利用的森林资源，但它担心用户能否不断得到家用原木和木材的供应。因为林业工人年事已高。(3)尽管有大量的可利用森林资源，但它担心用户能否不断地获得家用原木和木材。因为林业工人年事已高。(4)立木采伐成本与林地路径和采伐量相关。(5)由于优势切削条件在技术上没有得到充分体现，我们有必要在整个三川盆地进行精心布置的切削方案。(6)线性规划法分析在切割业务中的效果，通过改善切割地点和工作时间的分配，利润将大大增加。(7)运输成本是宫崎材扩大市场份额的障碍之一。然而，可以通过计划更多的合作运输和使用专用船来减少宫崎木材。(8)对林业的多重经营进行分析，其主要受工作能量因子消耗的影响，而不是受工作时间的影响。

(1) Since increasing the exchange rate of yen, imports of US and Canada lumber are increasing remarkably in the share of Japanese market. The other, a scale of saw mills of foreign logs become larger and more rationally than before.(2) According to the increase of machined precut of housing lumber for the deficiency of carpenters, the distribution of lumber became briefly, e. g., big housing makers purchasing, directly from sawmills without distinction of domestic or foreign.(3) In spite of the massive available forest resources, it worries that users can be constantly supplied with domestic logs and lumbers. Because forestry workers come to an advanced age.(3) In spite of the massive available forest resouces, it worries that users can be constantly supplied with domestic logs and lumbers. Because forestry workers come to an advanced age.(4) Cutting cost of stumpage timber is correlated to a wood land path and the cutting volume.(5) As the advantage cutting condition is not reflected enough in the technology, it is necessary for us to carry out on a well-laid cutting plan in the whole of Mimikawa basin.(6) The effect of Linear Programming Method analysis in the cutting business, the profit will be increased much more by improving the distribution of cutting places and working hours.(7) Transportation cost is one of the barriers to expand the market share of Miyazaki lumber. It, however, can be reduced by planning much more cooperative shipments and using exclusive ship for Miyazaki lumber.(8) Analyzing multiple management of forestry, it is powerfully affected by consumption of working energy factor rather than working hours.
