“…Afin de pallier cette absence, nous avons mis en place une méthodologie, intitulée SAMANTA (Situation Awareness Modeling & ANalysis for Transition Amelioration) et basée sur la modélisation des tâches et des éléments de conscience de la situation de l'opérateur. Cette méthodologie développée dans le cadre d'un doctorat en informatique au sein d'une équipe d'ergonomes, a fait l'objet d'une première évaluation théorique utilisant un jeu vidéo multi-joueurs comme étude de cas [14]. Afin de soutenir cette méthodologie et d'ainsi faciliter son usage par les ergonomes, un outil interactif a également été développé.…”

This article presents the methodology SAMANTA (Situation Awareness Modeling & ANalysis for Transition Amelioration) and its application to the analysis EPR nuclear power plants' operations. The methodology's key steps (modeling and transition analysis) are supported by a new web-based tool, which is described here. Its use is assessed through an expert analysis, leading to some recommendations regarding its improvement.

“…Meanwhile, two kinds of visualization tools were developed by [4][5][6], which indicated the network connectivity status and network traffic by using audit logs. [7][8][9][10] used the polar coordinate to show the connectivity status. All of these methods can not dynamically reinforce the most vulnerable node in real time.…”

To increase the security of network system, we propose a network security situation awareness method based on intercepting the threat spread. This method firstly merges security data from different sensors to get the normalization data of network nodes, threats and vulnerability. And secondly, the method intercepts the threat spread by the normalization data. Finally, the method constructs the game analysis among the attacker, defender and neutral. Then the system manager can reinforce the most vulnerable node in real time according to the analysis. Experiment results show that our method can stably improve the security performance of the network system with the system continuously running.

Task models produced from task analysis, are a very important element of UCD approaches as they provide support for describing users goals and users activities, allowing human factors specialists to ensure and assess the effectiveness of interactive applications. As user errors are not part of a user goal they are usually omitted from tasks descriptions. However, in the field of Human Reliability Assessment, task descriptions (including task models) are central artefacts for the analysis of human errors. Several methods (such as HET, CREAM and HERT) require task models in order to systematically analyze all the potential errors and deviations that may occur. However, during this systematic analysis, potential human errors are gathered and recorded separately and not connected to the task models. Such non integration brings issues such as completeness (i.e. ensuring that all the potential human errors have been identified) or combined errors identification (i.e. identifying deviations resulting from a combination of errors). We argue that representing human errors explicitly and systematically within task models contributes to the design and evaluation of error-tolerant interactive system. However, as demonstrated in the paper, existing task modeling notations, even those used in the methods mentioned above, do not have a sufficient expressive power to allow systematic and precise description of potential human errors. Based on the analysis of existing human error classifications, we propose several extensions to existing task modelling techniques to represent explicitly all the types of human error and to support their systematic task-based identification. These extensions are integrated within the tool-supported notation called HAMSTERS and are illustrated on a case study from the avionics domain. IntroductionTask analysis and modelling approaches have always focused on the explicit representation of standard behavior of users, leaving user error analysis for later phases in the design processes [2]. This is part of the rationale underlying task analysis which is to provide an exhaustive analysis of user behavior describing goals and activities to reach these goals. Clearly, errors, mistakes and deviations are not part of the users' goals and thus ...
