Situation Awareness With Systems Of Systems

This book discusses various aspects, challenges, and solutions for developing systems-of-systems for situation awareness, using applications in the domain of maritime safety and security. Topics include advanced, multi-objective visualization methods for situation awareness, stochastic outlier selection, rule-based anomaly detection, an ontology-based event model for semantic reasoning, new methods for semi-automatic generation of adapters bridging communication gaps, security policies for systems-of-systems, trust assessment, and methods to deal with the dynamics of systems-of-systems in run-time monitoring, testing, and diagnosis. Architectural considerations for designing information-centric systems-of-systems such as situation awareness systems, and an integrated demonstrator implementing many of the investigated aspects, complete the book.

Enhancing Situation Awareness (SA) is a major design goal for projects in many fields, including aviation, ground transportation, air traffic control, nuclear power, and medicine, but little information exists in an integral format to support this goal. Designing for Situation Awareness helps designers understand how people acquire and interpret information in complex settings and recognize the factors that undermine this process. Designing to support operator SA reduces the incidence of human error, which has been found to occur largely due to failures in SA. Whereas many previous human factors efforts have focused on design at the perceptual and surface feature level, SA-oriented design focuses on the operator's information needs and cognitive processes as they juggle to integrate information from many sources and achieve multiple competing goals. Thus it addresses design from a system's perspective. By applying theoretical and empirical information on SA to the system design process, human factors practitioners can create designs to support SA across a wide variety of domains and design issues. This book serves as a helpful reference to that end.

During natural disasters, disease pandemics, terrorist attacks, and other public health emergencies, the health system must be prepared to accommodate a surge in the number of individuals seeking medical help. For the health community, a primary concern is how to provide care to individuals during such high demand, when the health system's resources are exhausted and there are more patients than the system can accommodate. The IOM's Forum on Medical and Public Health Preparedness for Catastrophic Events held a workshop June 10-11, 2009, to assess the capability of and tools available to federal, state, and local governments to respond to a medical surge. In addition, participants discussed strategies for the public and private sectors to improve preparedness for such a surge. The workshop brought together leaders in the medical and public health preparedness fields, including policy makers from federal agencies and state and local public health departments; providers from the health care community; and health care and hospital administrators. This document summarizes the workshop.

The Annual (ICGS) International Conference is an established platform in which se- rity, safety and sustainability issues can be examined from several global perspectives through dialogue between academics, students, government representatives, chief executives, security professionals, and research scientists from the United Kingdom and from around the globe. The 2009 two-day conference focused on the challenges of complexity, rapid pace of change and risk/opportunity issues associated with modern products, systems, s- cial events and infrastructures. The importance of adopting systematic and systemic approaches to the assurance of these systems was emphasized within a special stream focused on strategic frameworks, architectures and human factors. The conference provided an opportunity for systems scientists, assurance researchers, owners, ope- tors and maintainers of large, complex and advanced systems and infrastructures to update their knowledge with the state of best practice in these challenging domains while networking with the leading researchers and solution providers. ICGS3 2009 received paper submissions from more than 20 different countries around the world. Only 28 papers were selected and were presented as full papers. The program also included three keynote lectures by leading researchers, security professionals and government representatives. June 2009 Hamid Jahankhani Ali Hessami Feng Hsu

Having an accurate understanding of what is going on is a key commodity for teams working within military systems. 'Situation awareness' (SA) is the term that is used within human factors circles to describe the level of awareness that operators have of the situation that they are engaged in; it focuses on how operators develop and maintain a sufficient understanding of 'what is going on' in order to achieve success in task performance. Over the past two decades, the construct has become a fundamental theme within the areas of system design and evaluation and has received considerable attention from the human factors research community. Despite this, there is still considerable debate over how SA operates in complex collaborative systems and how SA achievement and maintenance is best supported through system, procedure and interface design. This book focuses on the recently developed concept of distributed situation awareness, which takes a systems perspective on the concept and moves the focus on situation awareness out of the heads of individual operators and on to the overall joint cognitive system consisting of human and technological agents. Situation awareness is viewed as an emergent property of collaborative systems, something that resides in the interaction between elements of the system and not in the heads of individual operators working in that system. The first part of the book presents a comprehensive review and critique of existing SA theory and measurement approaches, following which a novel model for complex collaborative systems, the distributed SA model, and a new modelling procedure, the propositional network approach, are outlined and demonstrated. The next part focuses on real-world applications of the model and modelling procedure, and presents four case studies undertaken in the land warfare, multinational warfare and energy distribution domains. Each case study is described in terms of the domain in question, the methodology employed, and the findings derived in relation to situation awareness theory. The third and final part of the book then concentrates on theoretical development, and uses the academic literature and the findings from the case study applications to validate and extend the distributed SA model described at the beginning of the book. In closing, the utility of the distributed SA model and modeling procedure are outlined and a series of initial guidelines for supporting distributed SA through system design are articulated.

This book examines the human factors issues associated with the development, testing, and implementation of helmet-mounted display technology in the 21st Century Land Warrior System. Because the framework of analysis is soldier performance with the system in the full range of environments and missions, the book discusses both the military context and the characteristics of the infantry soldiers who will use the system. The major issues covered include the positive and negative effects of such a display on the local and global situation awareness of the individual soldier, an analysis of the visual and psychomotor factors associated with each design feature, design considerations for auditory displays, and physical sources of stress and the implications of the display for affecting the soldier's workload. The book proposes an innovative approach to research and testing based on a three-stage strategy that begins in the laboratory, moves to controlled field studies, and culminates in operational testing.

A comprehensive overview of different approaches to the measurement of situation awareness in experimental and applied setting, this book directly tackles the problem of ensuring that system designs and training programs are effective at promoting situation awareness. It is the first book to provide a all-inclusive coverage of situation awareness and its measurement. Topics addressed provide a detailed analysis of the use of a wide variety of techniques for measuring situation awareness and situation assessment processes. It provides a rich resource for engineers and human factors psychologists involved in designing and evaluating systems in many domains.
