Data Envelopment Analysis for Efficiency Measurement of Bridge Resilience

The resilience of a bridge is computed using different quantitative and qualitative assessment methodologies. However, the score obtained by these approaches insufficient for decision-makers setting priority level bridges in need improvement. To address this issue, present study develops methodology data envelopment analysis (DEA) approach. A total 12 are selected as decision-making units DEA model. This considers variables such age, area, design high flood level, finish road inputs, index output variable. Based on variables, three frameworks developed to compute efficiency resilience. variable return scale with output-oriented formulation all frameworks. Thus, proposed enables owners set improvement based scores methodology.
