1. A mobile tower yarder, RME200T, RME300TC operated by running skyline system was set on different sits of experimental area in the Funyu training forest. On each setting the geometric variables and haul line pulling out time by chorker setters have been measured. The study showed that choker setters could reduce the force exerted by about 20 to 50% when using the carriage equipped with self line extraction mechanism.2. Method for estimating the productivity of a logging system using data-mining program C4.5 was discussed its possibilities and limitations in o the detailed planning of a logging operation in the Funyu training forest. The results obtained clarified that the highest productivity of cable logging was found in yarding with a clear-cut operation or a thinning operation with 2 operators over a 30% thinning rate and under a 78m yarding distance.3. Cable layout method for mobile tower yarder was studied in a clear-cut logging operation. A time-study analysis of mobile tower yarder was used to estimate the machine productivity and operating cost. Analysis indicates that optimizing method using neural network model can be used to improve productivity of tower yarder system. Further result suggest that system productivity of clear cut area is highest when operation site is constructed in small blocks, average 100 to 150m main line cable distance.4. Optimizing method for forest road density using machine power was made up and studied. In this process, result of a time-study analysis of tower yarder, cable yarder and forwarder were used to estimate machine productivity indices and construction cost of forest road. Analysis indicates that optimizing method using machine power can be effectively used to improve the forest road density. Further result suggest that forest road density is highest when using small size yarding machine, and it rapidly decrease after 20 to 100PS.

1。通过运行天际线系统操作的RME200T，RME200T的移动塔院子设置在Funyu培训森林中的不同实验区域。在每个设置上，都测量了Chorker Setter的几何变量和拖拉线。该研究表明，使用配备自线提取机制的托架时，cho子设置器可能会降低约20％至50％的力。2。讨论了使用数据挖掘程序C4.5估算记录系统生产率的方法C4.5，在Funyu培训森林中对伐木操作的详细规划中的可能性和局限性进行了讨论。获得的结果澄清说，电缆记录的最高生产率是在码中发现的，具有清晰的操作或稀疏操作，有2个操作员以30％的稀疏速率和78m码以下的距离。3。在清晰的伐木操作中研究了移动塔院子的电缆布局方法。对移动塔院子进行了时间研究分析来估计机器的生产率和运营成本。分析表明，使用神经网络模型的优化方法可用于提高塔架系统的生产率。进一步的结果表明，当操作站点以小块为单位，平均100至150m主线电缆距离时，清除区域的系统生产力最高。4。使用机器功率进行了优化的森林道路密度方法，并进行了研究。在此过程中，使用了对塔架，电缆码和转发器进行时间研究的结果来估计机器生产率指数和森林路的建设成本。分析表明，使用机器功率的优化方法可有效地用于提高森林道路密度。进一步的结果表明，使用小尺寸码机时森林道路密度最高，并且在20至100ps后迅速降低。
