Sea freight transportation involves moving huge amounts of freights among maritime locations widely spaced by means of container vessels. The time required to serve container vessels is the most relevant indicator when assessing the competitiveness of a maritime container terminal. In this paper, two main logistic problems stemming from the transshipment of containers in the seaside of a maritime container terminal are addressed, namely, the Berth Allocation Problem aimed at allocating and scheduling incoming vessels into berthing positions along the quay and the Quay Crane Scheduling Problem, whose objective is to schedule the loading and unloading tasks associated with a container vessel. For solving them, two Migrating Birds Optimization (MBO) approaches are proposed. The MBO is a recently proposed nature-inspired algorithm based on theV-formation flight of migrating birds. In this algorithm, a set of solutions of the problem at hand, called birds, cooperate among themselves during the search process by sharing information within aV-line formation. The computational experiments performed over well-known problem instances reported in the literature show that the performance of our proposed MBO approaches is highly competitive and presents a better performance in terms of running time than the best approximate approach proposed in the literature.

This research proposes two optimization models to deal with the berth allocation problem. The first model considers the berth allocation problem under regular vessel arrivals to minimize the flow time of vessels in the marine container terminal, minimize the tardiness penalty costs, and maximize the satisfaction level of vessels’ operators on preferred times of departure. The second model optimizes the berth allocation problem under emergency conditions by maximizing the number of assigned vessels, minimizing the vessel’s waiting time, and maximizing the satisfaction level on the served ships. Two real examples are provided for model illustration under regular and emergent vessel arrivals. Results show that the proposed models effectively provide optimal vessel scheduling in the terminal, reduce costs at an acceptable satisfaction level of vessels’ operators, decrease the waiting time of vessels, and shorten the delay in departures under both regular and emergent vessel arrivals. In conclusion, the proposed models may provide valuable assistance to decision-makers in marine container terminals on determining optimal berth allocation under daily and emergency vessel arrivals. Future research considers quay crane assignment and scheduling problems.

Modeling unloading operations at maritime container terminals has increasingly become crucial to container terminal planners. This paper presents the multistage flexible flowshop scheduling problem (MFFSP). The objective of the MFFSP is to determine a schedule that minimizes the schedule length for a given number of containers and handling equipment over a finite planning horizon. Since the MFFSP is NP-hard in the strong sense, metaheuristic solution method is employed. A global lower bound to measure the efficiency of the metaheuristic procedure is derived. The optimization procedure is based on Genetic Algorithm (GA) which is used to estimate the minimum schedule length for a number of problem instances. Computational experiments validate the developed MFFSP.

Key Aspects

The COVID-19 pandemic had a serious impact on global trade in 2020. The interruption of the supply chains due to various restrictions influenced the rapid drop in the transport demand. In the last decade, the global containerized trade has noted the growth of approximately 55,5%, with an average pace of growth of about 5% yearly. Container shipping, as one of the industries vulnerable to economic shocks, has noted a significant drop in trade. The role of maritime container terminals as an integrator and facilitator of global trade in the global supply chains is undisputed. Therefore, the role of services provided by the maritime container terminals has grown in importance. This situation generates the necessity to adapt to these circumstances in a way that expresses the need of improving the service quality, as one of the key aspects of competitiveness. The purpose of this paper is to determine the possibility to verify the relation between COVID-19 impacts on maritime container transport and maritime container terminal service quality. Based on the findings the suggested actions for service quality improvement are proposed.

Sea container terminals are an important infrastructure element in the global supply chain. An increase in the number and size of container ships, as well as an increase in container traffic, led to the expansion of sea container terminals and an increase in their capacity. Extra-large container vessels require more handling equipment, as well as more storage space for containers, and increased throughput capacity for supporting infrastructures. To solve these complex problems in a global competition, the search for integrated effective solutions is required. The article proposes a solution to the integrated digitalization of the sea container terminal.

Container terminals help countries to sustain their economic development. Improving the operational efficiency in a container terminal is important. In past research, genetic algorithms (GAs) have been widely used to cope with seaside operational problems, including the berth allocation problem (BAP) and quay crane assignment problem (QCAP) individually or simultaneously. However, most GA approaches in past studies were dedicated to generate time-invariant QC assignment that does not adjust QCs assigned to a ship. This may underutilize available QC capacity. In this research, three hybrid GAs (HGAs) have been proposed to deal with the dynamic and discrete BAP (DDBAP) and the dynamic QCAP (DQCAP) simultaneously. The three HGAs supports variable QC assignment in which QCs assigned to a ship can be further adjusted. The three HGAs employ the same crossover operator but a different mutation operator and a two-stage procedure is used. In the first stage, these HGAs can generate a BAP solution and a QCAP solution that is time-invariant. The time-invariant QC assignment solution is then further transformed into a variable one in the second stage. Experiments have been conducted to investigate the effects of the three HGA and the results showed that these HGAs outperformed traditional GAs in terms of fitness value. In particular, the HGA3 with Thoros mutation operator had the best performance.

Different Characteristics

The growth of containerization and transporting goods in containers has generated capacity and equipment allocation problems in maritime ports. Container terminals represent complex systems with dynamic interactions between the various handling, transportation and storage units, and uncertainties about future events. Maritime container terminal operates at full capacity if the arrival of vessels to berth is uniform according to its capacity and equipment operating at constant parameters. Since there are random factors both on the arrival of ships and on the operation of equipments, the paper analyzes the influence of these factors on the terminal capacity. Therefore, we proposed a generic simulation model structure for the comparative assessment of the measures of performance of maritime terminal in ideal conditions (without perturbations in the terminal operation) and in different statistical assumptions of vessels inflows to berth and number of containers to unload per vessel. Based on event driven and virtual reality technology, the handling technology simulation model is developed using ARENA simulation software. The model is set-up by combining three basic functions: transport, transfer, and stacking. The transport activity is assumed by the flows of the container vessels and trucks. Different characteristics of the arrival flows are assumed (intervals between transport units, number of containers to unload). Quay cranes provide the container transfer. The stacking areas consist in one capacity area on the quay for the quick transfer on trucks. The simulation results lead to the conclusion that it can be achieved berth high occupancy and minimization of vessels waiting time at the port if the vessels inflows follow a distribution with small variance around the ideal value.

Truck Appointment System

In this paper a new approach for designing a truck appointment system (TAS) at container terminals is proposed. While the vast majority of published research analyzes the TAS from the perspective of drayage companies and terminal operations, in this work this topic is centered around truck drivers. The objective of this approach is to show that it is possible to increase the satisfaction of drivers which will maintain the positive effects that the TAS provides to the port. To be more precise, the focus is on exploiting the fact that individual truck drivers perform multiple visits to the container terminal in a day. Based on this information, a scheduling problem is defined and the corresponding integer programming model is developed. The potential benefits of the proposed approach are evaluated for the ports of Los Angeles and the port of Seattle. This has been done by generating problem instances based on the distribution of the number of daily truck visits to the port, number of daily working hours of drivers, and distances (lengths) of individual dray moves for the corresponding ports. The results of the conducted computational experiments show that using the proposed approach can positively affect gate waiting times and truck driver satisfaction. Further, it is shown that this type of approach favors more experienced drivers, which has a potential to provide additional benefits to the port.

Dendritic Shape

The maritime container terminal is no longer a spatially coherent object. Functionally it ends, where their most external components are located. The process of location splitting of container terminals (ger. Standortspaltung) can be treated as next stage of their discrete growth. The new container facilities are being built to improve the containers’ flow, passing from port terminals to cities situated in their hinterland and vice versa. The external components of container terminals have a very diverse program, are functionally complex, and due to advanced technologies of information and logistics they are interconnected into one system. The structure of the functional bindings of a maritime container terminal could be compared to the dendritic shape of a neuron, the kernel of which is a terminal, and the arms are transportation corridors ended with distant land intermodal terminals. The physical feature of this system is the logistics landscape with vast areas and large cubature. The aim of the paper is to present the graphical model explaining the changes in distribution and hierarchy of container terminals’ external elements in relation to the network of cities and transportation.

Maritime Container Terminal

The article describes a proposed planning organization and productivity simulation tool, with a special emphasis on orientations to the optimization of operations in a maritime container terminal. With the application of an adequate model frame for traffic and technical‐technologic forecasting, infrastructure and manpower planning and productivity simulation are possible to measure and increase the productivity in the whole subsystem of the maritime container terminal. The emphasis is mainly put on setting up planning organization in order to collect important information and consequently to raise productivity. This is the main task and goal of terminal management that must develop elements and strategies for optimal operational and financial production. An adequate planning structure must use simplified but efficient simulation tools enabling owners and management to take a vast number of adequate financial and operational decisions. Considering all important and very dynamic facts in container and shipping industry, the proposed simulation tool gives a helpful instrument for checking productivity and its time variation and monitoring a competitive position of a certain maritime terminal with the terminals from the same group. Therefore, the management of every maritime container terminal must establish an appropriate internal planning system as a mechanism for strategic decision support relating basically to the assessment of the best development and optimization solutions for the infrastructure and suprastructure of the entire system.
