Studies on the most suitable environment of a high proficient forestry machine workers

本报告的目的是使高熟练林业机械的可操作性和操作人员的工作负荷的关系清楚。研究了高熟练林业机械作业中操作人员的合理工作环境，并计划减轻操作人员的工作负荷。本报告研究了以下问题。(1)高效率林业机械的工作性能（2）高效率林业机械的工作性能和工作特性调查（3）各工作系统的工作负荷调查（4）林业工人工作时间分配和安排的规划（5）高效率林业机械的工作能力显示和最适宜工作环境的调查分析。指出了1998年林业工作中存在的工作负担问题。我们考虑了与工作环境和工作量的关系。去年检查了视力信息和工作量。对作业人员最适宜的工作环境进行了调查研究，认为取得了较好的效果。本研究的特点是从检测和作业比体侧负荷两方面对高效林业机械的作业特性进行了负荷评价。由于工作系统建设的必要性，它考虑到了一个工作特性，能力的发挥，通过考虑到操作人员的工作量评估。亚瑟考虑了一项建议，对建立工作制度，它采取了在最合适的工作环境的工作负荷的操作员。

The purpuse of this report to make operability of a high proficient forestry machines and relation with a work loads of an operators clearly. It examined reasonable work environment of operators in high proficient forestry machine work and was going to plan work loads reduction of an operator. This report studies the following problems. (1) Performance with a high proficient forestry machines (2) Work performance and work characteristic investigation with the high proficient forestry machine (3) Work loads investigation for each work systems (4) Planning of work time distribution and arrangement of a forest workers (5) Workability display in a high efficiency forestry machine and investigation analysis of most suitable work environment.The results are as follows : It pointed out problems of work burden caused from forest work in 1998. We considered relation with work environment and work load. The last year examined sight information and workoads. It enforces an investigation study about the most suitable work environment of an operator and thinks that it achieved. It was for the characteristic of this study to have arrested work load evaluation caused a work characteristic of a high efficiency forestry machine from examination and work than both sides' side of body burden load. As for the necessity of work systems construction that it took in a work characteristic, display of ability is achieved by taking in workload evaluation of operators. The Arthur considered a proposal toward establishment of the work system that it took in the most suitable work environment a work loads of an operators.
