Currently, container shipping plays an important role in international logistics. Terminals handle containers between different modes of transport and are a key element in supply chains. The quality of transport services, in general, depends on the technical and technological parameters of container terminals. At the same time, the task is to optimize the operating mode of the container terminal to reduce logistics costs. This article presents the results of a study of the traffic flows of terminals adjacent to the Tashkent regional railway junction stations, obtained based on timing observations on the unloading of containers arriving at the terminal by road for shipment by container trains. Based on these observations, the regularities of the distribution of the probabilities of the arrival of containers at the terminal and the time of servicing vehicles by a gantry crane were established. With the help of the established patterns, the main indicators were selected that characterize the quality of the container terminal functioning. A mathematical model has been developed and an algorithm for finding the optimal operating mode of a container terminal when forming a container block train. As the results of calculations have shown, the volume of logistics costs for the operation of a container terminal depends on the type and quantity of used handling equipment and the number of supply of fitting wagons to loading and unloading routes.

Container terminals are the main hubs of the global supply chain but, conversely, they play an important role in energy consumption, environmental pollution and even climate change due to carbon emissions. Assessing the environmental impact of this type of port terminal and choosing appropriate mitigation measures is essential to pursue the goals related to a clean environment and ensuring a good quality of life of the inhabitants of port cities. In this paper the authors present a Terminal Decision Support Tool (TDST) for the development of a container terminal that considers both operation efficiency and environmental impacts. The TDST provides environmental impact mitigation measures based on different levels of evolution of the port’s container traffic. An application of the TDST is conducted on the Port of Augusta (Italy), a port that is planning infrastructural interventions in coming years in order to gain a new role as a reference point for container traffic in the Mediterranean.

В работе отмечается, что одной из наиболее актуальных задач имитационного моделирования в области морских контейнерных перевозок является взаимодействие между собой контейнерных терминалов одного порта или нескольких портов морского побережья (морского фасада хинтерленда).По этой причине в статье рассматриваются методы оценки производительности причала, основанные на статистических данных и методе Монте-Карло, преимуществом которых является возможность оценить производительность всех операций контейнерного терминала с учетом случайного характера продолжительности отдельных движений путем наблюдения лишь за некоторыми, наиболее часто встречающимися операциями. Эти методы могут использоваться для решения задачи о взаимодействующих терминалах, когда суда осуществляют погрузо-разгрузочные операции на нескольких терминалах порта в рамках одного судозахода. Информация о производительности причала позволяет промоделировать данную систему без учета внутренних процессов контейнерного терминала. В работе доказывается, что существует зависимость между производительностью причала и размером судозахода судна. Корреляционно-регрессионный анализ позволил выявить наиболее подходящие формы зависимости линейную и степенную. В работе также получены оценки разброса выявленных зависимостей для целей имитационного моделирования. Полученная зависимость доказывает адекватность аналитических рассуждений о производительности причала, представленных в предыдущих работах.The paper notes that one of the most important tasks of simulation in the field of container shipping is the interaction of container terminals of one port or several ports of the sea coast (sea front of the hinterland) .For this reason, the article discusses methods for assessing the performance of a berth based on statistical data and Monte Carlo method, the advantage of which is the ability to evaluate the performance of all operations of the container terminal, taking into account the random nature of individual movements by monitoring only for some of the most frequently used operations. These methods can be used to solve the problem of interacting terminals when ships carry out loading and discharging operations at several port terminals within the framework of a single call. Information about the berth productivity allows to simulate this system without taking into account the internal processes of the container terminal. The paper proves that there is a relationship between the berth productivity and the size of the ships call. Correlation-regression analysis revealed the most appropriate forms of dependence - linear and power-law. The paper also obtained estimates of the spread of identified dependencies for the purpose of simulation. The obtained dependence proves the adequacy of analytical reasoning about the performance of the berth presented in previous works.

The City

The growth of container transport places increasing demand on traffic, especially in situations where container terminals are located near the city centers. The main problem is traffic congestion on networks caused by the integration of Heavy-Duty Vehicles and urban traffic flows. The main objective is to identify the critical traffic parameters which cause negative organizational and environmental impacts on the existing and future traffic demand. A micro-level traffic simulation model was implemented for the testing of the proposed framework-based supply, demand, and control layers. The model was generated and calibrated based on the example of a mid-size Container Terminal “Brajdica” and the City of Rijeka, Croatia. The results indicate that the critical parameters are Queue Length on the approach road to the Container Terminal and the Stop Delay on the main city corridor. High values of these parameters cause negative effects on the environment because of increased fuel consumption and the generation of extra pollution. Due to this problem, a sensitivity analysis of the traffic system performance has been conducted, with a decrement of Terminal Gate Time distribution by 10%. After re-running simulations, the results indicate the impact of subsequent variation in Terminal Gate Time on the decrease of critical parameters, fuel consumption, and vehicle pollution.

Finding solutions for improving the safety and quality of loading and unloading operations has therefore become very important. In this article, a fuzzy grey quality function deployment approach was developed to identify solutions for improving the safety of container terminal loading and unloading operations in Taiwan. First, the fuzzy grey quality function deployment approach was presented. Second, this study employed a house of quality to facilitate investigation of the 18 safety needs’ attributes and 10 feasible technical solutions. Safety needs, and their importance and satisfaction, were then examined via an expert questionnaire. Subsequently, a fuzzy relationship matrix was constructed to link technical solutions and safety needs in a fuzzy decision environment. Finally, the fuzzy grey quality function deployment approach was applied to prioritize technical solutions regarding improving the safety quality of container terminal loading and unloading operations in Taiwan. This study’s results show that the top six most feasible technical solutions for improving the safety quality of loading and unloading operations are “implementing professional education and training,”“enhancing safety awareness and behavior of personnel,”“developing effective standard operating procedures,”“adequate safety equipment,”“establishing a good safety climate,” and “regular maintenance of hardware and equipment.” These top six technical solutions are also discussed in this article.

Mode Of Transport

Maritime transport moves a majority of the goods and global trade around the globe. This mode of transport involves loading and unloading of containers at ports. Upon arrival at a port, the ships remain inactive during the operations of loading and unloading. The terminal operator receives a schedule indicating the dates of loading and unloading of containers and their locations in the storage areas. Once berthing takes place, ships are unloaded by gantry cranes to the handling area, where the containers are then collected for transfer to storage areas or buffer zones. Container terminals are essential inter-modal interfaces for the worldwide transportation network. An optimal location for a container terminal is very important for the operators and companies as it can minimize the number of unnecessary movements within the storage area and the terminal, which can reduce transportation costs. In this work, the authors propose a container placement problem and a solution approach through a model for decision support that can solved and optimized for the storage space available. In other words, a model that minimizes the total number of unnecessary movements, while respecting the dynamic constraints of space and time.
