Allocation of bridge maintenance costs based on prioritization indexes

Abstract Prioritization indexes (PI) are a need-based bridge maintenance approach, which allows making short-term maintenance decisions. They generally use just the bridge condition as an explanatory variable, therefore, prioritizing is easy to do. When these indexes are multidimensional, prioritiza...
