- Abstract
Criteria weights formulation is the most essential component of a multi-criteria prioritization scheme. The research reported in this paper sought to critically compare a recently developed multi-criteria optimization criteria weights method to the well-known analytic hierarchy process (AHP) as well as the method employed by the bridge management software BrM (formerly Pontis), which is licensed to all 50 State Departments of Transportation in the United States. Using four criteria for demonstration (bridge performance, utility, vulnerability to climate-triggered extreme events, and vulnerability to climate-triggered extreme loads), the new method clearly separates the concept of prioritization from the concept of optimization. The study demonstrates that there is an important and practical difference between a suitable criteria weight formulation for asset management optimization, on one hand, and the type of formulation required for a general selection problem, on the other hand. More importantly, the new method performs better than both the AHP and the BrM on all the important measures.
