Abstract

The occurrence of probabilistic common cause errors (PCCEs) in man‐machine systems can lead to multiple human errors being affected by common causes and will contribute greatly to the reliability of the system. In this paper, A reliability modeling method based on event tree (ET)‐fault tree (FT) model for man‐machine systems subjected to PCCEs is proposed. Under the influence of PCCEs, risk factors in the system are not independent, and human errors affected by the same common cause will occur with different probabilities. To describe the dependencies among risk factors, a PCCE gate is proposed to extend FTs in the ET‐FT model. To analyze the impact of common causes on the human error probabilities and quantify the extended FT, an explicit method and an implicit method based on the Cognitive Reliability and Error Analysis Method are proposed. The proposed quantification methods consider the different relationships among multiple common causes in a single model. Finally, the proposed methods are validated in the reliability assessment of the emergency response system under malfunction of the solar wing mechanism.

受概率共同原因错误影响的人机系统的可靠性评估

人机系统中发生的概率共因错误（PCCEs）会导致多个人为错误受到共因影响，从而极大地影响系统的可靠性。本文提出了一种基于事件树（ET）-故障树（FT）模型的可靠性建模方法，用于受 PCCEs 影响的人机系统。在 PCCEs 的影响下，系统中的风险因素并不是独立的，受相同共同原因影响的人为错误会以不同的概率发生。为了描述风险因素之间的依赖关系，提出了一个 PCCE 门，以扩展 ET-FT 模型中的 FT。为了分析共同原因对人为错误概率的影响并量化扩展的 FT，提出了基于认知可靠性和错误分析方法的显式方法和隐式方法。所提出的量化方法考虑了单一模型中多个常见原因之间的不同关系。最后，提出的方法在太阳翼机构故障情况下的应急系统可靠性评估中得到了验证。

期刊介绍： Quality and Reliability Engineering International is a journal devoted to practical engineering aspects of quality and reliability. A refereed technical journal published eight times per year, it covers the development and practical application of existing theoretical methods, research and industrial practices. Articles in the journal will be concerned with case studies, tutorial-type reviews and also with applications of new or well-known theory to the solution of actual quality and reliability problems in engineering. Papers describing the use of mathematical and statistical tools to solve real life industrial problems are encouraged, provided that the emphasis is placed on practical applications and demonstrated case studies. The scope of the journal is intended to include components, physics of failure, equipment and systems from the fields of electronic, electrical, mechanical and systems engineering. The areas of communications, aerospace, automotive, railways, shipboard equipment, control engineering and consumer products are all covered by the journal. Quality and reliability of hardware as well as software are covered. Papers on software engineering and its impact on product quality and reliability are encouraged. The journal will also cover the management of quality and reliability in the engineering industry. Special issues on a variety of key topics are published every year and contribute to the enhancement of Quality and Reliability Engineering International as a major reference in its field.
