为了准确表述能够诱发人为差错的情景环境,对人因可靠性分析(HRA)中的行为形成因子(PSF)进行归纳整理,构建一种新的系统化的PSF分类方法。对现有人因可靠性文献中的PSF进行分析,明确PSF的定义及其内涵。通过分析人机交互过程,指出PSF应该包含:操作者,机器,任务,组织,环境和辅助系统等6个方面,分别从上述6个方面对PSF进行细致分解,最终构建包括6个方面38个元素的PSF分类方法。 In order to accurately describe the scenario environment that can induce human error, this paper constructs a new systematic PSF classification method to summarize the behavior formation factor (PSF) in Human Reliability Analysis (HRA). The analysis of PSF in existing human reliability literature clarifies the definition and connotation of PSF. By analyzing the process of human-computer interaction, it is pointed out that the PSF should include six aspects: operator, machine, task, organization, environment and auxiliary system. The PSF should be carefully decomposed from the above six aspects, and the final construction includes 38 Elements of the PSF classification method.
