Ports are widely recognised as crucial nodes in international trade and transport. However, for various reasons, capacity does not always match demand: sometimes there is overcapacity, whereas in other cases, demand exceeds capacity and there is a shortage of the latter. This chapter therefore looks at where port congestion occurs, both globally and in the port-calling chain; it analyses actual responses by various chain actors, and it sheds some light on potential future evolution and reaction patterns.

Congestion, in general, can feature various forms of appearance: it can be more or less hidden, featuring congestion costs, or it can be visually present, featuring queues which are building up. The chapter discerns eight zones in the port-calling chain where congestion may emerge. As a result of a wide literature search, supplemented with a survey, it can first of all be observed that quite some congestion seems to occur, globally spread, and hitting larger as well as smaller ports. Most of the congestion is generated at the terminals, hinterland connection points and hinterland transport itself.

In terms of reaction patterns, one would assume that pricing throughout the system is adapted in such way that demand equals capacity. In practice, prices are hardly making any effort to make marginal revenue equal marginal cost. The reason is mainly that the power balance is quite strongly in favour of shipping companies, who impose on port and port operators the need to expand capacity at low fees. Port operators, in turn, apply various kinds of technical and procedural adaptations. The same is true for hinterland operators.

Looking towards the future, it seems that with the increase in world trade, the risk of port congestion will be even more outspoken, be it in some parts of the world more than in others. It is also very much likely that most problems will occur landside, as this is the part of the chain where solutions are least easy: who is going to take the initiative, how will co-ordination take place and where will the funding come from? Most actors seem to be aware of this trend, and seek for solutions like dedicated terminals and vertical integration or co-operation.

With the above observations, the chapter sheds some light on where the future needs and trends in the abatement of capacity will lie. It is therefore useful from a scientific point of view as well as with an eye on policy-making and operational port management.

There is significant amount of literature tackling different issues related to the port industry. The present chapter focuses on a single business unit of seaports aiming at the documentation of works related to container terminals.

An effort to review, collect and present the majority of the works present in the last 30 years, between 1980 and 2010, has been made in order to picture the problems dealt and methods used by the authors in the specific research field. To facilitate the reader, studies have been grouped under five categories of addressed problems (productivity and competitiveness, yard and equipment utilization, equipment scheduling, berth planning, loading/unloading) and four modelling methodologies (mathematics and operations research, management and economics, simulation, stochastic modelling).

The analysis shows that most works focus on productivity and competitiveness issues followed by yard and equipment utilisation and equipment scheduling. In reference to the methodologies used managerial and economic approaches lead, followed by mathematics and operations research.

In reference to future research, two fields have been identified where there is scope of significant contribution by the academic community: container terminal security and container terminal supply chain integration.

The present chapter provides the framework for researchers in the field of port container terminals to picture the so far works in this research area and enables the identification of gaps at both research question and methodology level for further research.

Brazil has been increasing its participation in the international trade market, mainly due to agricultural and forestry products, as in the case of soybeans and cellulose. This growth led to the expansion of the logistics infrastructure and its use. An important example of this trend is the port of São Luís, MA, in northern Brazil, which saw an increase in exports via rail (more than 200% growth in 6 years) and, consequently, an increase in the circulation of trains within its port complex.

This work proposes a mixed-integer linear programming model for the daily train scheduling problem at this port. All trains operated by VLI, a logistics company, are scheduled to minimize the departure times in order to improve the dwell time of freight train cars.

The railroad system in this Brazilian port consists of two classification yards, five terminals and a double-track railway for circulation. Different products such as grains, minerals, cellulose, and fuels are transported. The model also incorporates different operations at terminals and occupation restrictions due to maintenance and the physical flow of other third-party logistics companies. These features are modeled through a preprocessing step. In this phase, a series of auxiliary sets are defined to simplify constraints, circulation options are mapped, and the double-track is divided into segments based on the transit time with the objective to control track occupation.

This preprocess step also reduces the model complexity and, consequently, the computational time to solve it, as shown in the numerical tests using real-world operational data.

The main gains of the project were a reference train timetable for peak days, standardization of train crossing options, and a support tool for traffic adjustments with other rail operators.

Based on our experience related to the passenger terminal re-design at Sydney airport and its impact on belly-hold freight chains at the airport, this chapter takes a more general view on managing freight chains at large international airports. We aim to review literature and documents related to this area and also to undertake a fleet/traffic analysis of the 100 largest multi-function airports (when measured in terms of scheduled cargo traffic) to get a better understanding of current practice, particularly in the light of potential conflicts or benefits of the joint production of passenger and freight services. While most literature has focused on hub-and-spoke aspects of international hubs, relatively little has been done on economies of scale and scope of passenger and freight airline operations (including timing) at such hubs. This chapter explores to what extent terminal organisation of international airports impacts on the use of dedicated freighter of combination airlines and hence airline efficiency. A key finding in terms of airline efficiency is that economies of scale of air cargo operation appear to exist at the aircraft level as dedicated freighters are used more often if a sufficient threshold of air freight demand is observed at the airport level.

Container liner shipping companies started expanding their business by investing in container port terminals in the late 1990s. This market entry results in an extensive presence of vertically integrated liners and terminals. This study aims to explore the competition effects of this vertical integration trend based on a regional (European) analysis. In particular, it extracts lessons from the European Commission (EC) cases on the competition effects of vertical integration. The critical analysis of the cases examined at the institutional level intends to reach conclusions on whether liner–terminal vertical integration harmed or advanced competition in the relevant markets and/or the extent that there is a need to revise the current policy practices.

This study critically assesses the EC’s decisional practices in port container terminal vertical mergers in the last 25 years (1997–2021). Based on a literature review comparing maritime and competition economists' perspectives, it reviews the types of mergers examined, the methodology followed for relevant market definition and calculation of market shares and the estimated competition effects. The Hamburg–Le Havre area is the port range used as a case study for comparing the decisional practice with actual market developments. These container ports serve the greatest consuming market of final and intermediate goods in Europe and are gateways to Central and Eastern Europe.

The assessment identifies a need for expanding the investigation as a precondition for reaching conclusions on both the anti- and pro-competitive effects. First, only a limited number of transactions have been notified to the EC. Second, the empirical research identified a gap in this process, as there were no decisions (phase I) on vertical mergers between 2008 and 2016. Third, the exante assessment has not applied a phase II in-depth analysis to any case due to the absence of competition concerns. Finally, due to the absence of complaints, there is a lack of any ex post assessment of the effects of vertical integration.

This assessment is important for understanding the current and emerging features of intra-port and inter-port competition and the potential effects that the continuation and expansion of liner companies' vertical integration strategies will have along maritime supply chains. It also contributes to the broader discussion on liner companies' strategies, such as the research and policy-making efforts around the globe to understand the impact of both vertical and horizontal integration.

These discussions are critical for a diversity of businesses that use liner shipping services or provide facilities and services to container shipping lines or ports. They are important for the interests of customers and consumers as they could inform any needed re-visiting of competition policy to protect from the dominance of any market developments that would lead to conditions limiting competition. Expanding analysis on the competition effects of non-notified mergers would help a better understanding of market changes.

Enhancing competition and limiting monopolies is valuable from a consumer's perspective. This is more so in the case of maritime trade that serves the needs of societies. The study contributes by generating a better understanding of how decision-makers have worked towards that direction and what realignments are worthy.

There are no previous comprehensive reviews and analyses of the ways that policy-makers at the regional level have addressed the competition effects of vertical integration strategies of liner shipping companies when enhancing competition is valuable from a consumer perspective. Comparing maritime economists and competition, the study, via its literature review, also offers a comparison of maritime and competition perspectives on these competition effects, allowing positioning of how effective decisional-making practices have been.
