The current paper develops three different ways to measure the multi-period global cost efficiency for homogeneous networks of processes when the prices of exogenous inputs are known at all time periods. A multi-period network data envelopment analysis model is presented to measure the minimum...

This study evaluates the overall efficiency of aeronautical and non-aeronautical production process. Moreover, it investigates the each stage efficiency using network data envelopment analysis and compares the results with tradition DEA to find out the causes of inefficiency and analyze its...
