Human Reliabilty in the Performance of Maintenance

Abstract

A method for estimating the reliability of maintenance performance is developed and applied to tasks involved in scheduled maintenance for Titan II engines. The approach involves the combined use of ratings and empirically derived reliability figures. A modification of the design engineer's redundancy formula is developed for estimating the increase in human reliability achieved when two mechanics work together in the performance of a single maintenance task. This study demonstrates that highly consistent ratings of task-element- reliability can be obtained from groups of qualified raters. Plans for validating the human reliability estimates obtained during Category II testing at Vandenberg Air Force Base are described. Suggestions for further research and application of the findings are given.
