Safety culture is broadly recognized as important for operational safety in various fields, including air traffic management, power plant control and health care. Previous studies addressed characterization and assessment of safety culture extensively. Nevertheless, relations between safety culture and formal and informal organizational structures and processes are yet not well understood. To a...

The effectiveness of a Navigation Agent has been evaluated, which determines a path through course material tailored to the individual student. Lesson selection by the agent showed an advantage for students who were unable to monitor their own learning process. Initiative by the agent --where the agent also chooses the moment for selecting another lesson-reduced the time needed to finish the ta...

ethods of creating Plan Patches to update the plans separately held by each of the parties l b involved to keep them in step as they each react to changing circumstances in real-time wil e investigated. This will involve the specification of plan patch Attachment Points that can d be understood by the recipient. We will also investigate transaction based methods for coor inating the activities ...

We are developing an agent-based intelligent middleware for the Grid. It is based on agent teams as resource brokers and managers. Our earlier work resulted in a prototype implementation. However, our recent research led to a complete redesign of the system. Here, we discuss the new and main technical issues found during its implementation.

An agent-based simulation model representing a theory of the dynamic processes involved in innovation in modern knowledge-based industries is described. The agent-based approach allows the representation of heterogeneous agents that have individual and varying stocks of knowledge. The simulation is able to model uncertainty, historical change, effect of failure on the agent population, and agen...
