A Study of Evaluation Model of Human Errors at Risk for the Petroleum Operation

Abstract

Because the petroleum production is larger investment, higher risk, and the traditional risk evaluation tools usually gave an evaluated value only, which being not in accord with the actual, the paper introduces the ideas of Value at Risk into the Human Errors (HEs) quantification for the petroleum operation, and develops the the model of Human Errors at Risk (HEaR) to quantify the HEs. The model can in detail depict the actual risk statuses of production system under different risk conditions.
