Human Error Assessment and Management in Port Operations using Fuzzy AHP

This study proposes a new method of human error assessment and management using fuzzy set theory and analytical hierarchy process (AHP). The paper begins with a brief discussion of human reliability assessment (HRA) before presenting the new method. In assessing the human error risk using the proposed method, the steps in each mission are compared to each other in terms of the likelihood, failure consequence probability, and severity criteria to determine the relative importance and overall risk priority. The method is demonstrated using a test case of an oil cargo handling process in port. The method appears to be effective for evaluating the effectiveness of the risk control options identified and avoids some of the drawbacks of traditional HRA techniques.
