ABSTRACT
Bridges in Bhutan are prioritized for maintenance based on their priority score derived from the inventory and condition score. The inventory criteria, which includes the bridge attributes, remain consistent, while the condition criteria, which assess structural damage, vary across bridge types. This disparity in the condition scores influences the weights on the inventory and condition criteria across bridge types, which leads to differences in bridge rankings. To examine the degree of these differences, this study constructs a hierarchy based on the current weighting scheme, back calculates the weights, and then applies equal weighting across all bridge types to observe the effect on the rankings. This study offers insights into how non-uniform weighting schemes can alter the bridge rankings for maintenance priority, highlighting the impact of weight allocation on bridge prioritization.
