چکیده

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.
