Evaluating the environmental efficiency of a two-stage system with undesired outputs by a DEA approach: An interest preference perspective.
European Journal of Operational Research(2016)
摘要
•We propose a new DEA model to evaluate two-stage system environmental efficiency.•Our model combines individual interest preference with efficiency evaluation.•We proof the relationships between individual interest preferences and efficiencies.•Our model has a good power of evaluating the efficiency of chain system.•The empirical results truly reflect the current environmental situation in China.
