Evaluating Airlines Safety Using Fuzzy Simulation Technique

In this paper, a model based on fuzzy simulation technique and hierarchical structure analysis is developed to evaluate the airlines safety. With the use of linguistic terms, subjective assessments of qualitative safety measures are represented with fuzzy variable. The relative weights of safety attributes are assessed using a pairwise comparison process. Based on the concept of optimality, fuzzy simulation approach is employed to dispose of the evaluation model and compute the expected values of the airline. Then the shortcoming of the traditional analytic hierarchy process (AHP) is made up. Finally, an empirical study on Chinese three major domestic airlines is conducted to demonstrate the effectiveness of the approach.
