Stress and Ergonomic Design and Evaluation of Person-Machine Systems

摘要

This report was written to make system designers and developers more stress-conscious and more alert to sources of potentially harmful operator stress. They are then more capable of designing person-machine systems in which stress is optimized, in which equipment and operating procedures are a good fit to system operators. In such systems, worker morale and performance are maintained, and the lifecycle system costs are less. Despite careful design efforts aided by preproduction tests and evaluations, person-machine systems often come into wide use with unanticipated and potentially harmful stress-related operator problems. How this can happen is made evident by examining stress in general and stress in and out of the workplace. Examples of stress and strain are given. Stress from inadequate visual conditions is given special emphasis. The presentation is from ergonomic or application viewpoint. A stress checklist is given in the appendix.
