Available in PDF, EPUB and Kindle. Book excerpt: The research investigates the feasibility of modeling human performance errors in application to the reliability analyses of man-machine systems. The research addresses itself to time-continuous tasks with the derivation of a general mathematical model of the probability of errorless performance which is equated to human performance reliability. The application of this model and the implications of the time to first error concept were tested with a laboratory experiment using a vigilance task. The observed times to first miss error, times to first false alarm error, and times to first combined miss and false alarm errors were ordered and, through classical interference theory, the underlying density functions were isolated. A number of distributions were tested for goodness of fit with the data. The Weibull, Gamma, and log-normal distributions emerged as relevant paradigms. The normal and exponential distributions were rejected. It was concluded that the derived general mathematical model of human performance reliability and the expected value of the random variable, time-to-first-human-error, are meaningful ways to quantify human performance of time-continuous tasks.

This book was released on 2018-06-11 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: Humans play an important role in the overall reliability of engineering systems. More often accidents and systems failure are traced to human errors. Therefore, in order to have meaningful system risk analysis, the reliability of the human element must be taken into consideration. Describing the human error process by mathematical models is a key to analyzing contributing factors. Therefore, the objective of this research effort is to establish stochastic models substantiated by sound theoretic foundation to address the occurrence of human errors in the processing of the space shuttle.Elshamy, Maged and Elliott, Dawn M.

Download or read book Applications of Human Performance Models to System Design written by Grant R. McMillan and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 534 pages. Available in PDF, EPUB and Kindle. Book excerpt: The human factors profession is currently attempting to take a more proactive role in the design of man-machine systems than has been character istic of its past. Realizing that human engineering contributions are needed well before the experimental evaluation of prototypes or operational systems, there is a concerted effort to develop tools that predict how humans will interact with proposed designs. This volume provides an over view of one category of such tools: mathematical models of human performance. It represents a collection of invited papers from a 1988 NATO Workshop. The Workshop was conceived and organized by NATO Research Study Group 9 (RSG.9) on "Modelling of Human Operator Behaviour in Weapon Systems". It represented the culmination of over five years of effort, and was attended by 139 persons from Europe, Canada, and the United States. RSG.9 was established in 1982 by Panel 8 of the Defence Research Group to accomplish the following objectives: * Determine the utility and state of the art of human performance modelling. * Encourage international research and the exchange of ideas. * Foster the practical application of modelling research. * Provide a bridge between the models and approaches adopted by engineers and behavioral scientists. * Present the findings in an international symposium.
Download or read book Human Reliability written by K.S. Park and published by Elsevier. This book was released on 2014-06-28 with total page 355 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objectives of Human Reliability are to build reliability into the job, into the machine, and into the environment, and to let man perform naturally. In this book the author shows how these objectives can be achieved by concentrating on human reliability issues during the design stage. This is done by illustrating the relationships between various design features and some aspect of human performance, e.g. human errors.The book is designed as a practical guide to the daily performance of tasks in Human Reliability as well as a general reference and tutorial introduction to the field. It is therefore both practical and theoretical: the first four chapters focus on principles and ramifications relevant to human error prevention; the latter four are primarily concerned with human reliability analysis and prediction methodology. Throughout the book there are extensive references, numerous ready-to-use recommendations, formulas and mathematical models, and computer programs for human reliability work for analyzing, predicting and preventing human errors in a variety of situations. Though some of the material requires undergraduate training in engineering, the more difficult mathematical expositions can be omitted without loss of continuity, but are available for the reader who needs a more complete understanding of the relevant theory.

Available in PDF, EPUB and Kindle. Book excerpt: The development of the theory of fuzzy sets was motivated largely by the need for a computational framework for dealing with systems in which human judgement, behavior and emotions play a dominant role. Although there are very few papers on fuzzy sets in the literature of psychology and cognitive science, the theory of fuzzy sets provides a much better model for human cognition than traditional approaches.

Book excerpt: This book describes and evaluates existing models of human performance and their use in the design and evaluation of new human-technology systems. Its primary focus is on the modeling of system operators who perform supervisory and manual control tasks. After an introduction on human performance modeling, the book describes information processing, control theory, task network, and knowledge-based models. It explains models of human performance in aircraft operations, nuclear power plant control, maintenance, and the supervisory control of process control systems, such as oil refineries. The book concludes with a discussion of model parameterization and validation and recommends a number of lines of research needed to strengthen model development and application.
Download or read book Quantifying Human Performance Reliability written by William B. Askren and published by . This book was released on 1971 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human performance reliability for tasks in the time-space continuous domain is defined and a general mathematical model presented. The human performance measurement terms time-to-error and time-to-error-correction are defined. The model and measurement terms are tested using laboratory vigilance and manual control tasks. Error and error-correction data are ordered and the underlying density functions isolated. The Weibull distribution is best fit for time-to-first-error data, and the Log-Normal distribution is best fit for time-between-errors and time-to-error-correction data. Distribution parameter values are applied to the general mathematical model, and prediction made of human performance reliability for the tasks.

Download or read book Human Reliability And Error In Medical System written by B S Dhillon and published by World Scientific. This book was released on 2003-09-05 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human reliability and error have become a very important issue in health care, owing to the vast number of associated deaths each year. For example, according to the findings of the Institute of Medicine in 1999, around 100000 Americans die each year because of human error. This makes human error in health care the eighth leading cause of deaths in the US. Moreover, the total annual national cost of the medical errors is estimated at between $17 billion and $37.6 billion.There are very few books on this subject, and none of them covers it at a significant depth. The need for a book presenting the basics of human reliability, human factors and comprehensive information on error in medical systems is essential. This book meets that need.
Download or read book Human Factors in the Ground Control of Aircraft written by V. David Hopkin and published by . This book was released on 1970 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: The actual and potential contributions of human factors to the smooth and efficient functioning of systems for the ground control of aircraft are described and discussed. These systems are concerned with air traffic control or air defense, which fulfill different roles but share many human factors problems. The nature of the human factors contribution at each stage in the evolution of a ground control system is described. Much work has dealt with displays, controls, or communications, or with man's role in complex man-machine systems. Individual differences are considered in relation to selection, training, and screening procedures, and some of the differences which appear most relevant in systems are discussed. Both traditional and new methods for measuring operators are examined in terms of their merits and limitations. The factors of potential relevance to task performance are very numerous, and certain advances in other applied or academic contexts may be adapted with profit to ground control systems. Many of the proposed solutions to human factors problems have been based on limited evidence, mainly because man is treated primarily as a system component. Numerous studies have produced findings related to a specific task, but few widely applicable facts have emerged. Some probable future trends in the application of human factors to ground control systems are suggested. (Author).
Download or read book Human Factors Testing and Evaluation written by D. Meister and published by Elsevier. This book was released on 2014-06-28 with total page 437 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human factors measurement has characteristics that set it apart from psychological or engineering measurement and for that reason, human factors testing and evaluation deserves special treatment. The many excellent texts available in the behavioral area do not give an adequate picture of this topic, and this is particularly unfortunate because testing and evaluation (T&E) is an integral part of human-machine system design and operation. The emphasis in this book is on why and how to conduct such testing. One of its outstanding features is its pragmatism; based on his past experience in system testing, the author recognizes the difficulties that occur in testing and indicates how these may be overcome or minimized. Special attention has been paid to the context in which T&E is conducted. Although the book contains detailed procedures for performing T&E, the logic and the conceptual foundation of testing have not been overlooked. Comparisons are made with laboratory-centered experimentation. For those with research interests, the author points out the many research questions that can be answered by system testing. An illustrative case history of a T&E program for a fictional system has been included to provide ``real life'' context. Special problem areas in T&E are emphasized, in particular human error data collection, the evaluation of computerized systems and software, the measurement of maintenance technician and team performance; workload and training effectiveness testing. Special attention is also paid to environmental testing (e.g. temperature, lighting, noise, vibration, etc.). One chapter reviews all the relevant T&E literature including government documents that may not be readily available to the general reader. As part of the preparation for writing this text a survey was made of 45 distinguished T&E specialists in order to determine their characteristic T&E practices.The book will be useful not only to the human factors professional who specializes in T&E, but to all students and practitioners interested in human factors and work measurement.
