Prioritizing management issues of moving dangerous goods by air transport

This paper presents an expert survey-based approach for prioritizing management issues of dangerous goods transportation faced by air-transport-related sectors in Taiwan. A two-stage survey process is used to ask the experts to first identify and then evaluate the management issues. To develop effective-management priorities, these issues are evaluated in terms of their importance, urgency, achievability, and effectiveness, based on experts’ comparative and absolute judgments. A pairwise comparison process is used to help the experts make comparative judgments, while a linguistic rating method is used for absolute judgments. To reflect the inherent imprecision involved in the survey process, experts’ assessments are represented by triangular fuzzy numbers. To obtain an overall priority value, a fuzzy multiattribute decision-making method is used.
