Human Performance: What Improvement from Human Reliability Assessment

Abstract

The increasing technological complexity and scale of process plants demands proportionate attention to the contribution of human performance if public safety and capital investment are not to be jeopardised. In some industries there exists a strong long-term commitment to human factors engineering to maximise human reliability and to ensure that the generally good engineering reliability inherent in most plants is not to be frustrated by human error which now provides a major contribution to unreliability. This unreliability results from activities in design, construction, operation, but predominantly in maintenance and testing.
