Decomposition weights and overall efficiency in two-stage additive network DEA.
European Journal of Operational Research(2017)
摘要
•We investigate the factors in influencing the variations in overall efficiency of additive network DEA approach.•Variation in overall efficiency can be associated with constant stage efficiencies.•We examine relation of overall efficiency to the stage efficiencies and weights.•We propose a new of overall efficiency to reflect entirely on the stage efficiencies.
