Abstract :
In a recent paper in this journal, Yang et al. [Feng Yang, Dexiang Wu, Liang Liang, Gongbing Bi & Desheng Dash Wu (2009), supply chain DEA:production possibility set and performance evaluation model] defined two types of supply chain production possibility set which were proved to be equivalent to each other. They also proposed a new model for evaluating supply chains. There are, however, some shortcomings in their paper. In the current paper, we correct the model, the theorems, and their proofs.
