Abstract:
The special position of container terminals in the freight chain, has made evaluating the relative efficiency of container terminals one of the most essential tools of managers. In this study, we will evaluate the performance of these terminals by developing a network data envelopment analysis model tailored to the container terminal structure. So in the second chapter of this study, we present a comprehensive definition of processes, the parts, operations and services that are running at a container terminal. The relationship between processes and departments was also clearly identified. Eventually the structure of the container terminals was defined as a five-step network model, which consists of three main processes implemented in five steps. In this model, based on the container inlet and outlet flow at the container terminal, the relationship of the various segments is considered to be a complex one (a combination of series and parallel inter-segments). In this study, in order to evaluate the performance of container terminals according to the network structure which was introduced, the analysis of the network data envelopment was the most appropriate method of performance evaluation. Using the network data envelopment analysis technique requires a set of appropriate indicators. For this purpose, we used the Delphi method and presented the most effective indicators from the perspective of a panel of academics and port managers for each section of the container terminals. Finally, we developed a network data envelopment analysis model for container terminals into a five-step model. Also, a case study was used to investigate the model presented by optimization software, GAMS, and problem solving operator, cplex, on the data of Iran's eight port container terminals. The results of the problem solving show the accurate identification of efficient and inefficient parts of each container terminal using the proposed model.
