The interrelationship between the productivity of helicopter yarding operation and various operational conditions was investigated, using the quantification method, on Japanese National Forests in the three-year-period following 1983. It was confirmed that the kinds of helicopters had the greatest effect on the productivity of helicopter yarding operations, and the tree species, average volume per log, payload, and so forth followed. The productivity under different operational conditions could be predicted by the results of this quantification method analysis.Also the interrelationship between the cost of helicopter yarding operation and various operational conditions was investigated, using the quantification method, on Japanese National Forests in 1986. It was confirmed that the average yarding distance had the greatest effect on the cost of helicopter yarding operations, and the tree species, average height above sea level in the yarding area, and average volume per log followed, but on the other hand, the kinds of helicopters and average payload per cycle had little effect on the cost. The cost under different operational conditions could be predicted by the results of this analysis.

在1983年的三年期间，使用量化方法研究了直升机码运行的生产力与各种操作条件之间的相互关系。证实，这些直升机的种类对直升机院子的生产力最大，对直升机院子的生产力以及平均数量，平均数量，每货物，每款付费载荷和下载量。 The productivity under different operational conditions could be predicted by the results of this quantification method analysis.Also the interrelationship between the cost of helicopter yarding operation and various operational conditions was investigated, using the quantification method, on Japanese National Forests in 1986. It was confirmed that the average yarding distance had the greatest effect on the cost of helicopter yarding operations, and the tree species, average height above sea level in the yarding area, and average volume per log紧随其后的是，但另一方面，每周周期的直升机和平均有效载荷对成本的影响很小。本分析的结果可以预测不同操作条件下的成本。
