The objective of this research is to design and demonstrate an agent-based modeling and analysis tool for evaluating General Aviation (GA) pilot situation awareness under free flight air traffic management (ATM). A computational tool is developed to assess free flight’s potential effect on GA operators, by combining an agent-based representation of the overall pilot/vehicle/ATM system with quan...

The goal of this research is (a) to investigate the effects of task practice on situation awareness (SA); (b) to investigate how cognitive ability – in particular, working memory – moderates this practice effect on SA; and (c) to investigate effects of the SA measurement procedure (covering or uncovering the display while queries are answered). Task practice and working memory influence SA. How...

In a corporate network, the situation awareness (SA) of a security analyst is of particular interest. The current work describes a cognitive Instance-Based Learning (IBL) model of an analyst’s recognition and comprehension processes in a cyber-attack scenario. The IBL model first recognizes network events based upon events’ situation attributes and their similarity to past experiences (instance...

The simulation of the behaviour of autonomous entities in space is an interesting research method to advance our understanding of the interaction of human beings with the environment. Although rather complex cognitive models of human-level Situation Awareness (SA) in dynamic environments exist, computational approaches to represent the same remain at best ad-hoc – cognitively inadequate or bear...

Data Fusion System should maximize throughput during the complex fusion analytics in order to extract the critical information from a huge amount of data. Therefore, there is an immediate need to leverage efficient and dynamically scalable data processing infrastructure for the analysis of the Big Data streams from multiple sources in a timely and scalable manner. This is necessary for establis...

The notions of ‘‘situation’’ and ‘‘situation awareness’’ have been formulated by many authors in various contexts. In this paper, we present a formalization of situations that is compatible with the interpretation of situation awareness in terms of human awareness as well as the situation theory of Barwise and Devlin. The purpose of this paper is to capture the situation theory of Barwise in te...

This paper presents the concept of unmanned vehicle situation awareness and provides a discussion of how unmanned vehicle situation awareness can be defined based upon human situation awareness. A broadly accepted human situation awareness definition is directly applied to the notion of unmanned vehicle situation awareness. The paper also discusses unique unmanned vehicle aspects that will infl...

This paper explores the relationship between Situation Awareness, Common Operating Pictures and Data Fusion to expose the need for Situation and Impact Assessments. A framework for Situation Assessments is then proposed and illustrated through reference to footage from the movie, “The Hunt for Red October”
