Airport Safety Risk Evaluation for Bureaucrats Using Fuzzy ANP and the Generalized Choquet Integral Method

Yavuz Ozdemir


Abstract. Assessment and management of risks in the aviation sector is a difficult problem. There are many variables and uncertainties that affect aviation risk process. Implementing verbal security systems are not enough for today’s world security level and there are requirements to apply qualitative methods in order to deal with problems. Also bureaucrats, who use airports much more than civilian population, must deal with their own safety issues as airport safety, transportation safety, etc. For this reason, in this paper the evaluation of airport safety risks for bureaucrats using fuzzy numbers is studied. Besides ensuring bureaucrats’ safety, the aim of this paper is to determine the interdependency among main criteria and subcriteria, the nonlinear relationship among them and the environmental uncertainties. Multi criteria-decision making techniques, fuzzy Analytic Network Process (ANP) and Choquet integral methods are used for evaluation and the results of both algorithms are compared. As a result, it is fair to say that selecting Alternative A3 is the most reasonable and the most feasible outcome among 3 alternative location. The main advantage of the proposed model is to indicate the impact of the interactivity. The main contribution of this paper is to determine the interdependency, the nonlinear relationship and the environmental uncertainties. To the author’s knowledge, this will be the first study for airport safety risk evaluation for bureaucrats which compares the results of fuzzy ANP and Choquet integral methods.
