Human Error Models for Structural Reliability

This paper presents models for human errors to be used along with reliability analyses. The models account for the occurrence of errors, their magnitude, and the detection of the errors. The magnitude of the errors are separated into gross errors and cumulative errors. It is assumed that a single gross error is sufficient to cause failure, and the cumulative errors must accumulate in order to cause failure. Statistics for the models were acquired by surveying undergraduate engineering students. Monte Carlo simulations are used to arrive at quantitative results.
