Computer Control and Human Error presents accounts of various incidents at computer-controlled plants. These incidents include equipment and software faults; treating the computer as a "black box"; misjudging the way operators respond to the computer; errors in the data entry; failure to inform operators of changes in data or programs; and unauthorized interference with peripheral equipment. The discussion then turns to the use of hazard and operability studies (Hazops) to prevent or reduce errors in computer-controlled plants. The book describes the conventional Hazop as used in the process industry and an overview of the different Chazop frameworks/guidelines suggested by engineers and researchers. It then presents new Chazop methodology which is based on incident analysis. The final chapter presents reasons for failures in computerized systems, each of which is illustrated with an example. Most of the examples did not cause an actual safety problem, simply because they occurred within systems that are not safety-related. Some of these examples appear in the literature; others are from personal experience or from private communications.

Safety of Computer Control Systems 1983: Achieving Safe Real Time Computer Systems contains the proceedings of the Third IFAC/IFIP Workshop held at Cambridge, UK on September 20-22, 1983. Composed of 36 chapters, separated into the eight sessions of the workshop, this book begins with a discussion of the safety and reliability of computer control systems. Subsequent chapters explore the systems design for safety and reliability; fault tolerance, recovery, and use of redundancy; and aspects of fault tolerance for system reliability. Other chapters detail specification techniques; system development and quality assurance; verifications and validations; case studies; as well as scheduling, networks, and communications.

The User-Computer Interface in Process Control: A Human Factors Engineering Handbook is a handbook of human factors engineering guidelines for the design of the user-computer interface in process control applications. It describes the principles and practice of human factors engineering in the design, development, and acquisition of computer systems for process control, with emphasis on visual display use and design. This book consists of 10 chapters and begins by explaining what human factors engineering is, along with its role in computerized process control and some of the factors that contribute to deficient user-interface design. The discussion then turns to the principles of systems development and how they relate to human factors issues during the design process. The following chapters focus on the application of human factors guidelines to visual display units (VDUs); the strategy, method, and format for selection and organization of variables that may have an effect on human performance with specific application to user-computer interface issues such as brightness, contrast, and flicker; and various hardware aspects of VDUs. Controls and input devices, control/display integration, and workplace layout are also considered. This monograph will be a useful resource for software engineers, system designers, and project managers.

Human error is so often cited as a cause of accidents. There is perception of a 'human error problem'. Solutions are thought to lie in changing the people or their role. The label 'human error', however, is prejudicial and hides more than it reveals about how a system malfunctions. This book takes you behind the label. It explains how human error results from social and psychological judgments by the system's stakeholders that focus only on one facet of a set of interacting contributors.

The proceedings of the fifth workshop in this subject continue the trend set by the previous four and discusses some of the current problems involved in the design and production of safe real-time computer systems. Topics covered include software quality assurance, software fault tolerance, design for safety, and reliability and safety assessment. Every paper details the theoretical and practical problems involved in the development of safe systems and should therefore be of interest to all those involved in systems design.

th HESSD 2009 was the 7 IFIP WG 13.5 Working Conference in the series on Human Error, Safety and Systems Development which looks at integration of usability, human factors and human–computer interaction within system - th velopment. This edition was jointly organized with the 8 TAMODIA event on Tasks, Models and Diagrams for User Interface Development. There is an obvious synergy between the two previously separated events, as a rigorous, - gineering approach to user interface development can help in the prevention of human error and the maintenance of safety in critical interactive systems. Following the tradition of HESSD events, the papers in these proceedings address the problem of developing systems that support human interaction with complex, safety-critical applications. The last 30 years have seen a signi?cant reduction in the accident rates across many di?erent industries. Given these achievements, why do we need further research in this area? Recent accidents in a range of industries have increased concern over the design, management and control of safety-critical systems. Therefore, any system that involves human lives in its functioning is subject to safety-criticalaspects. Contributions such as the one by Holloway and Johnson (2004) report that over 80% of accidents in aeronautics are attributed to human error.
