This is a collection of codes for data envelopment analysis (DEA) computation based on Julia programming language and JuMP modeling language, which is as fast as AMPL and faster than any other modeling tools such as GAMS and Pyomo (see this).
example.jl is a simple JuMP code for the input-oriented CRS (CCR) model.
basicDEAmodel.jl is the code for computing DEA models based on input- or output- orientation and different returns to scale.
outlierDetection.jl implements the model to detect efficient and inefficient outliers (Chen and Johnson, 2010).
