Sustainability evaluation of the supply chain with undesired outputs and dual-role factors based on double frontier network DEA
The performance analysis of supply chain is a very complicated problem. The network DEA can be used to calculate efficiency of decision-making units with multiple stages. In this paper, a new network DEA model is proposed. This model includes undesired outputs and dual-role factors. It can calculate optimistic and pessimistic efficiency. The supply chain can be ranked in terms of the overall efficiency scores. A case study is presented to demonstrate the applicability of our model.
