Abstract

The traditional analytic hierarchy process (AHP) method can only compare a very limited number of decision alternatives. When there are hundreds or thousands of alternatives to be compared, the pairwise comparison manner is obviously infeasible. In this paper we propose a hybrid AHP/DEA methodology to facilitate the risk assessment of hundreds or thousands of bridge structures, where pairwise comparisons are impossible.
