Introduction: Cranes are of the major causes of accidents in the construction industries. As human error mostly causes crane accidents, this study aims to investigate the human errors of tower crane operators in the construction projects using SHERPA and CREAM techniques. Material and Method: In this research, first, all of the tasks of the tower crane operator were identified and analyzed. Th...
The design of interactive systems for use in complex dynamic domains often leads to new technology that is introduced into evolving and ongoing operational practice. It could be said that in this new technology system builders design primarily for data availability, not necessarily operability. Operability is taken to be the responsibility of the operator: it is (s)he who must find the right da...
Human-machine systems have become more and more risky and tightly coupled. Component failures can result in unacceptable disasters that not only affect workers and plants, but also neighbours and the environment. System Reliability Analysis has made noticeable progress in assessing technical component reliability, but the introduction of Human Reliability Analysis is more of difficult task. Thi...
Background and Objectives: Despite contribution to catastrophic accidents, human errors have been generally ignored in the design of human-machine (HM) systems and the determination of the level of automation (LOA). This paper aims to develop a method to estimate the level of automation in the early stage of the design phase considering both human and machine performance. Methods: A quantita...
Introduction: Human factors studies have shown that about 80% of the root causes of major accidents affecting safety, the environment or ergonomics are related to human error. The purpose of this study was to identify human errors using the HFACS method and the FAHP theory in cement industry. Methods: The present study was a retrospective study carried out in the cement industry. At first, R...
Introduction: Considering the accreditation of international standards of hospitals and the necessity to improve the safety and quality of patients’ care, this study aimed at evaluating reliability among nurses using predictive analysis of cognitive errors and human event analysis techniques. Material and Methods: The analysis of nurses̓ tasks was done by HTA method. Then, the types of errors a...
Human Reliability Analysis aims at identifying, quantifying and proposing solutions to human factors causing hazardous consequences. Quantifying the influence of gives rise error probabilities, whose estimation is a cumbersome problem. Since these are usually related other organisational or technological factors, it has been proposed apply probabilistic graphical models, such as Bayesian credal...
