Paper Title
Comprehensive Analysis of Multi-Dimensional Port Performance Efficiency of Port Efficiency Assessment Models with the Help of a Complex Model

Abstract
The transport sectors are developing dynamically. The volume of conveyances is increasing not only in the interior of certain countries, but also in the international traffic. The global transport system encompasses all types of long-distance transport and international conveyances form the basis for the functioning of the global market. The increase in the turnover of international goods leads to relevant increase in freight traffic. The efficiency of port performance is an important requirement to survive in the fiercely competitive freight sector, where every port struggles to attract and handle as much freights as possible.The aim of this study is to improve the methodology for assessing the efficiency of port performance by identifying the positive aspects and weaknesses in the port performance efficiency assessment model, as well as to develop suggestions for improving the port performance efficiency assessment model.The following tasks are set to achieve the goal:based on selected literature, to explore port performance efficiency assessment models and calculation methods, as well as the latest scientific conclusions on the researched problem; to study the role of ports in the economic growth of the transport sector; to identify key performance indicators of the efficiency of ports that could be used to analyse the efficiency of ports; to develop options for improving the port performance efficiency model. Theoretical and methodological basis of the study. When developing the study, research by S. Esmer, K. Bichou, W. C. Huang, J. Tongzon, P. Langen, M. were used. Also the results of the research carried out independently by the Author were used in the study, as well as information available on the Internet and in the international scientific databases.In order to successfully achieve the goal of the study and to meet the set goals, the Author uses Data Envelopment Analysis (DEA) and Stochastic Frontier Analysis (SFA) in the study.
