in today's competitive market, quality has an important role in manufacturing system. the manufacturers attempt to maintain their production system in a proper condition to produce high quality products. one of the key factors to achieve this goal is maintenance policy. most studies on maintenance focused on machines and less attention has been paid to human resources as the most important...

human factors are among the main elements affecting the reliability of nondestructive examinations (nde). in a man-machine system, human reliability is affected by many factors (performance shaping factors) whose influence on reliability cannot be easily expressed quantitatively. this paper identifies and ranks 59 perform-ance shaping factors by using a fuzzy reasoning method and proposes a pro...

In a large-scale study of how people find topical shifts in written text, 27 annotators were asked to mark topically continuous segments in 20 chapters of a novel. We analyze the resulting corpus for inter-annotator agreement and examine disagreement patterns. The results suggest that, while the overall agreement is relatively low, the annotators show high agreement on a subset of topical break...

The increasing complexity of industrial systems requires the adoption of adequate approaches to manage emergency situations in case of accidents and disasters. In this context the analysis of human reliability represents a crucial task [2]. In fact, the human factor is a predominant element in the study of accidents/disaster, both in probability level, but also in terms of severity of the expec...

Although considered as not safety critical (safety function being performed by other sub-systems), railway supervision systems can contribute to hazardous scenarios. It is of primary importance to identify this type of scenarios and evaluate the behaviour of human operators. A state of the art in human reliability is presented. This article presents an experimental protocol based on an automati...
