The case study airline has established a Flight Operation Risk Assessment System (FORAS) to evaluate the risk of a flight two hours before its departure; nevertheless, the function of critical risk factor identification and its corresponding adjustment suggestion is absent in the system. The present study proposes a search algorithm that is based on FORAS and its fuzzy reasoning mechanism to carry out the function of critical risk factor identification and adjustment suggestion. The algorithm is triggered when the risk of a flight is beyond the warning line. A target risk value in the safety zone is given, and the algorithm traces backward along the fuzzy rules in FORAS and finds the critical factors and the required changes of these factors to meet the target risk value. To justify the performance of the proposed algorithm, the real flight data from the case study airline are used, and the results are compared with that by a genetic algorithm.
