基于改进CREAM的无人机操作员人因可靠性分析

Analysis of Human Reliability on Unmanned Aerial Vehicle Operators Based on Improved CREAM

随着无人机的大量应用,无人机可靠性问题也被人们日益关注.目前关于无人机可靠性的研究主要集中在优化设计及整体系统可靠性,无人机操作员可靠性尚不多见.针对无人机操作的特点,分析建立了无人机操作员CPC因子集,并利用序关系分析法确定了CPC因子的贡献度,最后建立了CPC因子综合效应与控制模式之间的连续函数,对无人机操作员人因可靠性进行实例分析.结果表明,改进的CREAM方法更加科学合理,对无人机操作员可靠性研究具有一定指导意义.

With the wide application of Unmanned Aerial Vehicle(UAV), the reliability of UAV has received increasing attention. Currently, related research mainly focuses on the optimal design and the reliability of the whole system, studies on human reliability of UAV operators have rarely been reported. According of the features of the UAV system, the CPC factor set of UAV operators is established by CREAM method, and the contribution of CPCs is determined by rank correlation analysis. Using improved CREAM method, continuous function between CPC factors and control modes is constructed. The case results show that the improved method is more scientific and reasonable, and it has certain guiding significance for the human reliability of UAV operators.
