Situation awareness of operators plays a key role in the safety of a nuclear power plant. The establishment of a situation awareness assessment model (SAAM) is the foundation of an advanced HRA method. The paper firstly ascertains the relation between situation awareness and human reliability analysis and then forms an organization-committed cause-effect conception model. On the basis of the above,...
Human-computer interaction (HCI) is greatly influenced by findings in psychological research concerning interaction with complex technical processes. Psychological concepts like perception and comprehension of information, as well as projection of future system states can be summarized as situation awareness. Poor situation awareness can increase the probability of human error during interaction,...
Medication management process in a hospital includes all the work that is done concerning to a certain patient's medical treatment. According to international studies, the process is very prone to errors, which can cause adverse drug events and endanger the patient safety. In this paper, we will show how medication management process can be improved by a user-centric and computer-based automated dose-dispensing...
This paper deals with the integration of multiple advanced driver-assistance systems (ADAS) and in-vehicle information systems (IVIS) in a holistic driver-support system. The paper presents the results of a project named Integrated Safety Systems (INSAFES), which was part of PReVENT: an integrating project carried out under the European Framework Programme 6. Integration in INSAFES is tackled at three...
We extend techniques for a reachability-based abstraction to continuous systems under shared control, that is, systems which have both inputs controlled by the automation and inputs controlled by the human, to account for potential interactions between the human and the automation that affect safety. We broadly classify human input as assisting the automated input, neutral, or fighting against the...
Human-Machine-Interfaces are with no doubt one of the constitutive parts of an automation system. However, it is not till recently that they have received appropriate attention. It is because of a major concern about aspects related to maintenance, safety, achieve operator awareness, etc has been gained. Even there are in the market software solutions that allow for the design of efficient and complex...
This paper presents work in progress on a project to develop a process for integrating human reliability analysis (HRA) into the design process used in nuclear power plant modernization and upgrade projects. Human factors, probabilistic risk, and human-system interface design experts were interviewed, resulting in six principles for the use of HRA in design. These principles are: (i) early implementation,...
In the context of crises in which emergency services or the general population are of different languages, effective interoperability requires not only that translations of messages and alerts be done rapidly but also, being safety critical, that there be no errors. We have developed a methodology based on linguistic norms and a supporting mathematical model for the construction of a single source...
Efforts are underway to optimize the roles of man and machine in the control of liquid-metal-cooled fast breeder reactors. The work reported here describes: 1) a methodology for the decomposition of the control process into a hierarchical structure, 2) an explicit methodology, Sequencing Established States, to limit the state space search for process control and, 3) the Procedure Prompting System...
