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

(1)自日元升值以来，美国和加拿大进口木材在日本市场的份额显著增加。另一方面，国外原木厂的规模比以前更大、更合理。(2)随着木工不足的住宅木材加工预切量的增加，木材的分布短暂地变成了大型住宅制造商直接从锯木厂采购，不分国内和国外。(3)尽管有大量的可用森林资源，但它担心国内原木和木材可以源源不断地供应给用户。因为林业工作者进入了高龄。(3)尽管有大量的可用森林资源，但它担心用户可能会不断地获得国内的原木和木材。林木采伐成本与林地路径和采伐量相关。(5)由于采伐条件的优劣在技术上没有得到充分的体现，因此有必要在整个三川流域内进行合理的采伐计划。(6)线性规划方法在采伐业务中的作用，通过改善采伐地点的分布和工时的分配，利润将会大大增加。(7)运输成本是扩大宫崎材市场份额的障碍之一。然而，可以通过计划更多的合作发货和对宫崎材使用专属船舶来降低。(8)分析林业的多重经营，它受到工作能源消耗因素的强烈影响，而不是工作时间。

(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.
