Port efficiency remains a critical area of study within maritime economics, with Data Envelopment Analysis (DEA) emerging as a pivotal methodological tool. DEA provides a non-parametric framework for ...

Data envelopment analysis methods classify the decision making units into two groups: efficient and inefficient ones. Therefore, the fully ranking all DMUs is demanded by most of the decision makers.
