Crewmembers play an important role in ensuring the efficiency of \"crew-spacecraft\" system. However, despite of the fact that crewmembers are well trained and highly motivated persons, extreme flight factors may influence negatively on their reliability, and lead to human error occurrence. Therefore, working out methods of human error prevention is very significant to increase crewmember's performance reliability. Human error can occur in the operation of systems for a number of reasons. Within the framework of the present investigation, with use the data collected during \"Mir\" station missions, the significant (p<0.05) positive correlation of crewmembers errors (CE) frequency with their psychophysiological state (PPS), and work and rest schedule (WRS) intensity has been revealed. Differently, the higher WRS intensity, the crewmember's PPS is worse, and CE frequency is higher. This finding has been based on substantiations of the approach to human reliability management. Its essence will consist of the following: reducing WRS intensity, we thus can improve a crewmember's PPS and, accordingly, reduce CE frequency. This approach is discussed in the paper. 相似文献

软件度量用于软件开发过程和软件产品质量的评定，在ＮＡＳＡ航天飞机指挥控制中心改造工程的测试阶段，采用了五种度量，除一种度量之外，其它度量均提供了很有用的信息，根据我们的经验，我们建议在软件开发的测试阶段使用这些度量，同时提出另外的侯选度量供进一步研究。 相似文献

The methods presently applied in the psychological training of astronauts are based on the principle of ensuring maximum performance of astronauts during missions. The shortcomings are obvious since those undergoing training provide nothing but the best ability to cope with Earth problem situations and add simply an experience of space problem situations as they are presently conceived. Earth attitudes and Earth behaviour remain and are simply modified. Through the utilization of interdisciplinary space knowledge a much higher degree of problem anticipation could be achieved and the astronaut be psychologically transformed into a space-being. This would at the same time stimulate interdisciplinary space research. The interdisciplinary space knowledge already available suggests that space requires not only physical and mental adjustments, but a profoundly new relationship with life. 相似文献
