摘要

This paper discusses the concept of using quantitative risk assessment (QRA) techniques to make specific decisions regarding competing risks associated with specific maintenance policies. This paper is based on a project performed for a major international airline to assess the risk trade-off between a potential catastrophic event occurring during a maintenance procedure versus the possibility of inadvertently leaving a safety device in place following plane takeoff. The paper demonstrates the use of simplified event trees, human reliability analysis, and risk-based decision making.
