Airline safety measurement using a hybrid model

Abstract

Although air transport has a good safety record, public perception often focuses excessively on accidents. Safety is affected by many factors such as management, operations, maintenance, environment, aircraft design, and air traffic control. Quantitative measurement of the airline safety index is the goal of this paper. Some previous efforts to measure aviation safety have assumed the criteria to be independent, but this is not the case in the real world. Here a hybrid multiple criteria decision-making model to address dependent relationships among criteria, using a decision-making trial and evaluation laboratory along with an analytical network process, to decide the relative weights of criteria, showing inter-dependence and feedback.
