A Review of Current Human Reliability Assessment Methods Utilized in High Hazard Human-System Interface Design

摘要

This paper has three objectives. The first is to discuss the role that human reliability assessment implemented in human systems interface design. The second is to present significant characteristics of available HRA techniques. The third is to provide our viewpoints of the applicability of HRA methods in HIS design. Generally, HRA approaches advocate seven stages, problem definition, performances shaping factors analysis, task analysis, human error analysis, effect analysis, error reduction strategies, and evaluation of recommendations. The most difficult technique is the human error probability estimation and prediction. There are four shortcomings of past human error probability estimation and prediction methods. First, the reliable data is deficient. Second, there are insufficient criteria for choosing PSFs. Third, there is a limited capacity for evaluating cognitive behavior. Finally, possible causes are ignored. To look into the above-described problems, this study reviewed present HRA methods and proposed several aspects for future HRA method development.
