Abstract: We correct the results by Wu et al. Although Wu et al. proposed an integer-valued data envelopment analysis (DEA) model, which is based on Charnes-Cooper-Rhodes (CCR) model, the displayed results are based on an integer-valued DEA model, which is based on Banker-Charnes-Cooper (BCC) model. Therefore, we introduce the true models and corresponding results.
