Data envelopment analysis (DEA) can convert fractional linear efficiency into a linear programming model for decision analysis. DEA evaluates decision-making units (DMUs) using a nonparametric method. It is a mathematical programming method for assessing DMU performance. This method does not identify general relationships between all units. DEA is a frontier-based statistical regression method. In this chapter, two examples of DEA application in civil engineering are provided. Two of the applications relate to structural design engineering and earthquake engineering, respectively.
