Assessing the operational efficiency of Danube ports within the trans-European transport network

The paper analyzed 16 ports on the Danube that are part of the Trans-European Transport Network with the aim of calculating their efficiency, using the DEA method. The indicators included in the analysis, which represent the input indicators, are the number of operators, the total port area, the maximum depth of the river in the observed port, the number of terminals, the length of the quay, the maximum capacity of the anchorage area, and the storage capacity, while the output indicator is the amount of cargo handled. The results of the analysis showed that out of 16 analyzed ports, 6 ports are efficient, which enabled further evaluation of efficient ports using SWARA and WASPAS methods. After the analyze, the port that is ranked as the best is the port of Giurgiu, which has the largest number of operators and the largest number of terminals. The port of Dunajvaroš has the lowest efficiency, because of the smallest storage capacity and the smallest port area. The testing of the developed model showed the exceptional convenience of its practical application. The contribution of the paper is distinguished by the development of a model that is unique in terms of methods and variables included in the calculation.
