| Summary | This paper provides critical remarks and remedies to a recent article pub-lished in this Journal, volume 35, number 4, page 391-414, by Lin, Yu and Yang (2006). In their article, the authors employed the data envelopment analysis (DEA) and assurance region (AR) approaches to investigate the operational ef-ficiency for three major ports in Taiwan. The present paper points out the faults or errors found in their article in terms of variable selection, scale efficiency measurement, window analysis, and some erroneous statements in literature re-views. It is hoped that this will make more appropriate and much clearer the DEA applications to port’s performance evaluation. |
