Determining the Relative Efficiency of Container Terminals in Turkey Using Fuzzy Data Envelopment Analysis

Abstract

In this study, fuzzy data envelopment analysis (FDEA) was conducted to determine the relative efficiency of the container terminals operating in Turkey. For this purpose, the data from the container terminals were converted into fuzzy values using the “set of α cuts approach” and the upper and lower limit values for each terminal were determined. The lower and upper limit efficiency values were calculated using the input-oriented CCR-FDEA method. The minimax regret approach was used to sort and compare the relative efficiency of terminals. According to the resulting efficiency scores, one container terminal was effective at all α cutting levels. It was calculated that the four container terminals had the lowest values at all α cutting levels regarding the maximum efficiency loss values of other container terminals.
