“…The secondgeneration methodologies that have appeared on the basis of former category and are still being developed, put stress on cognitive information-processing to explain causes of human error. The relatively salient techniques are CREAM [22,23], MERMOS [24], and ATHEANA [25]. The third-generation, known as next-generation methodologies, is emerging to bridge the gaps of the both previous HRA generations.…”

Investigation reveals that a high percentage of incident causes are ascribed to some forms of human error. To effectively prevent incidents from happening, Human Reliability Analysis (HRA), as a structured way to represent unintentional operator contribution to system reliability, is a critical issue. Human Error Reduction and Assessment Technique (HEART) as a famous HRA technique, provides a straightforward method to estimate probabilities of human error based on the analysis of tasks. However, it faces varying levels of uncertainty in assigning of weights to each error producing condition (EPC), denoted as assessed proportion of affect (APOA), by experts. To overcome this limitation and consider the confidence level (reliability or credibility) of the experts, the current study aimed at proposing a composite HEART methodology for human error probability (HEP) assessment, which integrates HEART and Z-numbers short for, Z-HEART. The applicability and effectiveness of the Z-HEART has been illustrated in the de-energization power line as a case study. Furthermore, a sensitivity analysis is fulfilled to investigate the validity of the proposed methodology. It can be concluded that Z-HEART is feasible for assessing human error, and despite the methodological contributions, it offers many advantages for electricity distribution companies.

From its first applications to the military domain, HRA progressed to applications in Nuclear Power Plants (NPPs) operations, when development and validation of methods mainly targeted their use in Probabilistic Risk Assessments. In recent years, advances in HRA include the extension to various application fields, the development of new methods or enhancement of existing ones, data collection efforts, among others. These advances are possible due to the increasing number of authors on HRA and collaboration between them. Systematic literature reviews have been increasingly used for understanding various aspects of a research field. While recent reviews have provided an overview of the topics addressed by HRA research, the social structure of the field has not yet been fully explored. This paper discusses the social structure of HRA through 70 years of literature. The review aims at responding to how the links between different authors groups were created, that is, which large-scale projects, geographical proximity, or research topics contributed to these connections. The results indicate that (1) while the research on HRA was mostly based in the U.S.A. before 2000, China, Japan, and South Korea are significant contributors to the recent literature; (2) despite the increasing diversity of application fields, such as applications to the maritime and offshore industry, the main focus on NPPs operations is persistent since the 1980s; (3) due to large research projects, favored by a connected world, the physical workspace does not limit current collaboration among authors.

“…Their main tasks include the explora tion of marine geology, the investigation of submarine environments, indepth sea exploration, highprecision topographic surveying of oceans, and the detection and capture of new materials on the seabed. The manned sub mersible cabin is the space where the oceanauts operate, and it is usually designed as a small and spherical hull [2] and sampling, and high-definition video photography. Because of the complexity of the system, the psychologi cal quality and the physical function of oceanauts are very important for the safe and efficient operation of the sub mersible.…”

Objectives:The proper porthole angle contributes to relieving the operation fatigue and improving the efficiency of oceanauts. In this study, the au thors explored the effect of 3 different porthole longitudinal positions on the oceanauts' back muscles using surface electromyography (sEMG) analysis, and the characteristics of the perceived body comfort was obtained. Material and Methods: Overall, 40 healthy participants were recruited to perform tasks in a simulated cabin environment. Electromyographic (EMG) signals were recorded from the trapezius medius, lower trapezius, and erector spinal muscles for porthole angles of -5°, -15°, and +15°, relative to the horizontal line of sight during a 21-minute experiment. The subject comfort scores were collected at 7, 14 and 21 min. The integrated electromyogram (iEMG) and the root mean square (RMS) of EMG signals, as well as the mean power frequency (MPF), and the mean frequency (MF) were calculated. Results: The subjective scores of the +15° porthole at each stage of work are higher than those of the -15° and -5° portholes. The results of iEMG, RMS, MF and MPF all indicated that the +15° porthole design was more conducive to lowering the rate of muscle fatigue, while the -5° and -15° portholes increased the muscle fatigue rate and led to greater fatigue. It was found that the lower trapezius was more prone to fatigue than the trapezius medius and erector spinal muscles. The height, weight and body mass index of the participants were found to negatively correlate with muscles at the +15° porthole, which is highly consistent with the actual situation. Conclusions: The findings suggested that the +15° position was optimal for delaying the muscle fatigue of the participants and for improving the work efficiency of oceanauts.
