Abstract

ABSTRACT Objective: This study is to construct a model composed of multiple indices to measure astronaut teleoperation performance. Background: Teleoperation is a key operation during spaceflight. Comprehensive scientific evaluation techniques for teleoperation performance are important for astronaut selection and training. Method: Four categories of indices, i.e., completion performance, safety performance, subjective cognitive performance and physiological parameters, were adopted in this model. The fuzzy analytic hierarchy process (AHP) was used to compute the weight coefficients of the indices to construct the linear performance model. Sixty-four male subjects were recruited to complete three teleoperation tasks, including point aiming, line alignment, and obstacle avoidance, in simulated environments. Their performance was rated by the researchers after the tasks. Results: The safety performance index had the highest weight coefficient (0.5274) of the first level indices, and the weight coefficient of the collisions index (0.8227) was the highest of the second level indices for safety performance. The linear performance model was constructed to calculate comprehensive performance values. Conclusion: Safety considerations are the most important factors for astronauts to consider in teleoperation. The collision of the robotic arm is the most vital safety index. The comprehensive value derived from the model was significantly related to overall performance. The validity of our model was verified, and it is anticipated that the model will be used to evaluate the performance of remote robotic arm operations.
基于模糊层次分析法的遥操作性能评价模型
摘要目的:本研究旨在构建一个由多个指标组成的模型来衡量宇航员的遥操作性能。背景:遥操作是航天飞行中的一项关键操作。遥操作性能综合科学评价技术对航天员选拔和训练具有重要意义。方法:本模型采用完成感、安全感、主观认知能力和生理参数四类指标。采用模糊层次分析法(AHP)计算指标的权重系数,构建线性绩效模型。64名男性受试者在模拟环境中完成三项远程操作任务,包括点瞄准、直线对准和避障。研究人员在完成任务后对他们的表现进行了评分。结果:在一级安全性能指标中,安全性能指标的权重系数最高(0.5274),在二级安全性能指数中,碰撞指数的权重系数(0.8227)最高。建立了线性性能模型来计算综合性能值。结论:安全考虑是宇航员在遥操作中最重要的考虑因素。机械臂的碰撞是最重要的安全指标。从该模型中得出的综合价值与整体绩效显著相关。我们的模型的有效性得到了验证,预计该模型将用于评估远程机械臂操作的性能。
