The rapidly developing technology of command and control and decision support systems requires improvement in the way the human element is integrated into the system. The limitation of human cognitive capacity must not be exceeded, or the system will fail. A properly designed decision support system should include provision for the heuristics that are likely to be employed by a decision maker when faced with a rapidly changing and and information intensive situation and incomplete or questionable data. Many measures to effectiveness have bee proposed for battle management and C2 systems. In this paper, where system consist of an integrated combination of a human decision maker and his decision support system, three measures of effectiveness are proposed and discussed. Improvements in performance of the total system can be made by improving the efficiency of information exchange between the DM and the support system. The KOALAS architecture has been shown to be an effective implementation of a simulation and rule based expert system which can increase the efficiency of information exchange between the human decision maker and the decision support system. Potential improvements in KOALAS' architecture are discussed with recommendations for improving its employment and utility.
The choice to include the human in the decision process affects four key areas of system design: problem representation, system analysis and design, solution technique selection, and interface requirements specification. I introduce a design methodology that captures the necessary choices associated with each of these areas. In particular I show how this methodology is applied to the design of an actual decision Support system for satellite operations scheduling. supporting the user's ability to monitor the actions of the system and to guide the decision process of the system are two key considerations in the successful design of a decision support system. Both of these points rely on the correct specification of human-computer interaction points. Traditional, computer-centered system design approaches do not do this well, if at all, and are insufficient for the design of decision support systems. These approaches typically leave the definition of human-computer interaction points till after the component and system level designs are complete. This is too late however since the component and system level design decisions can impose inflexible constraints on the choice of the human-computer interaction points. This often leads to the design of human-computer interaction points that are only "good enough." These approaches result in ill-conceived problem representations and poor user-system interaction points because the system lacks the underlying architecture to support these constructs efficiently. Decision support systems require a new, human-centered design approach rather than the traditional computer-centered approaches.
A succinct guide to a Human Factors programme of work This book provides a reference for project managers to assist in identifying the key rudiments of good Human Factors design. It is intended to be used in conjunction with an appointed Human Factors manager as part of a detailed design programme, read by all engineers and designers in order to establish a wide understanding across the whole team of the importance of Human Factors. Human Factors in Military and Industrial Control Room Design offers succinct advice, tailored for rapid injection into complex Human Factors programmes, together with applicability to any control room design, military or industrial. Applications include warship control rooms, command centres, fire and accident response centres, chemical plants, nuclear installations, oil rigs, refineries and other similar industries. Key features: A template for a thorough Human Factors programme of work. Applicability to any control room design. Aims to address operator workload and optimise system performance, comfort and safety. Can save significant costs by optimised system integration and enhanced system operation. It is advised that project managers use Human Factors in Military and Industrial Control Room Design as a template to develop a control room "Operating Philosophy" and "Human Computer Interface (HCI) Style Guide" for their own purposes within the constraints of their specific industry.
In April 1991 BusinessWeek ran a cover story entitled, "I Can't Work This ?#!!@ Thing," about the difficulties many people have with consumer products, such as cell phones and VCRs. More than 15 years later, the situation is much the same-but at a very different level of scale. The disconnect between people and technology has had society-wide consequences in the large-scale system accidents from major human error, such as those at Three Mile Island and in Chernobyl. To prevent both the individually annoying and nationally significant consequences, human capabilities and needs must be considered early and throughout system design and development. One challenge for such consideration has been providing the background and data needed for the seamless integration of humans into the design process from various perspectives: human factors engineering, manpower, personnel, training, safety and health, and, in the military, habitability and survivability. This collection of development activities has come to be called human-system integration (HSI). Human-System Integration in the System Development Process reviews in detail more than 20 categories of HSI methods to provide invaluable guidance and information for system designers and developers.
There is no shortage of available human factors information, but until now there was no single guide on how to use this information. Human Factors Methods for Design: Making Systems Human-Centered is an in-depth field guide to solving human factors challenges in the development process. It provides design and human factors professionals, sys
