U.S. import/export container flow modeling and disruption analysis

International containerized freight movement is a vital part of the supply chain for many companies, and a critical element of moving consumer goods to points of retail sale within the U.S. Containerized imports also present a clear security concern (e.g., terrorists attempting to ship “dirty bombs,” chemical, biological or even nuclear weapons, into the U.S. in a shipping container). The goal of the research presented here is to create a modeling tool for analyzing flows of U.S. imports and exports of containerized freight, and the potential changes in those flows under a variety of conditions (e.g., port disruptions, extensive security-related delays, etc.). Our focus is on movements through maritime container ports, and not overland movements between the U.S. and Canada or Mexico.The network model, referred to as the System for Import/Export Routing and Recovery Analysis (SIERRA), represents container movements between the U.S. and 46 other countries that account for the vast majority of U.S. imports and exports. The SIERRA model is a network equilibrium model that predicts flows between foreign countries and North American ports, the total volumes handled (import and export) by each port, the modal volumes (truck and rail) moving domestically into and out of each port, and volumes between each port and a set of transportation analysis zones within the U.S.     

Marketing management at the world's major ports

Recent technological developments in maritime transport, particularly in container shipping and larger vessels, are having major repercussions at ports the world over. The latest wave of innovations has increased the level of competition in maritime transport, in particular in port activities. Shippers have many more alternatives available, something that tends to increase the hinterland of each port, precisely by reducing captive hinterlands. Ports are now generally moving towards formulas in which private initiative has a bigger role to play. Increases in competition combined with growth in private initiatives highlight the usefulness of marketing tools in two ways. Externally, because they help to achieve throughputs from remote points of origin and destination, and internally, by aiding the proper coordination of business and organizational activity at a commercial port. The present paper is a transversal study of the current situation of marketing and quality tools at major ports, including the opinions of a range of port commercial and marketing managers. We have also tried to describe the differentiated groups to be found at ports, as a useful methodology for identifying the nearest competition or ports with similar characteristics.

Port privatization under Cournot vs. Bertrand competition: a third-market approach

By incorporating port competition into a third-market model consisting of two exporting firms and one importing country, we demonstrate the endogenous choice of port structures (i.e. privatization or public ownership) under either Bertrand or Cournot competition. In contrast to previous studies on port competition, we analyze the port strategy in view of all trading countries (i.e. importing country and exporting countries). We find that regardless of transport cost, the port ownership strategy alters according to exporting firm’s competition mode. Under Bertrand competition, the choice of port ownership structure depends on the degree of imperfect substitutability. However, under Cournot competition, all trading countries choose same ownership structures of each port. By comparing equilibrium of each competition mode, we show that welfare of exporting country under Cournot competition is higher than under Bertrand competition if goods are sufficiently substitutes. In contrast, importing country prefers Bertrand competition to Cournot competition when the competitive pressure is sufficiently high.

The impact of port choice on inland transportation

The Belgian government intends to shift part of its funding away from Antwerp and towards other seaports, particularly Ghent and Zeebrugge. In the long run, this policy change will undoubtedly influence the port choice and probably cause a traffic diversion at the expense of Antwerp. This will have a great influence on the structure of inland transportation.

The impact of port choice on inland transportation is the central theme of this paper. To this end a disaggregated model of the demand for freight transport is constructed.     

Impact of politics,economic events and port policies on the evolution of maritime traffic in Chinese ports

The Chinese government has been exploring various paths to find a direction that better suits China’s national conditions during the past 60 years. Meanwhile, a series of political and economic events and policy transformations have had different effects on the port industry. This article attempts to ascertain how these events and port policies have influenced Chinese port traffic through an empirical study on data covering 1952–2009. The findings suggest that foreign trade has been the prime driver of the throughput of Chinese ports. The increase in the ports’ throughput has enabled an increase in domestic demand and the urgent need for further port investment. Chinese port throughput has been subject to multiple shocks. The Great Leap Forward¹ is found to have had the largest, but only a short-term impact. China’s accession to the World Trade Organization, however, led to a longer and exclusive effect on ports, with little observed effect on the other variables. The reform of port governance is shown to have had a more lasting positive effect on port throughput than physical investment. However, these latter effects are minor, the economic and political factors remain the primary driving factors of port throughput.     

Competitiveness between short sea shipping and road freight transport in mainland port connections; the case of two Greek ports

While road freight transport is essential to any modern economy, short sea shipping (SSS) offers a competitive alternative mode of freight transport in terms of private and social costs, when applied in the connection of mainland ports. This mainly stems from the fact that within the context of the latter costs, accidents and environmental impacts in many road links constitute undesirable externalities with which road freight transport is heavily burdened. This paper compares the aforementioned economics of road and sea transport with reference to the connection of the port of Patra (the main western freight gate of Greece) with West Attica (the biggest Greek industrial centre), aiming at providing a viable solution towards the promotion of SSS in the transport chain between mainland ports.     

Competitive status of US ports in the mid-1980s

Competition among US ports has heightened significantly in the 1980s, in large part due to the rising importance of intermodal transportation systems. This paper measures the shares of national waterborne imports and exports for the eight largest US ports and their changes between 1985 and 1987. It examines the decline of East-Coast ports, especially New York, and the ascendancy of their West-Coast counterparts, notably Los Angeles and Seattle, on the basis of 42 commodity groups. Finally, it documents the minibridge and reverse minibridge systems as they pertain to the emerging pattern of winners and losers.     

Tanzanian coastal and inland ports and shipping: crises and policy options

This paper explores the current state of coastal and inland shipping in Tanzania. It provides an overview of the state of ports and shipping in Tanzania, and the reasons underlying the present crisis of competitiveness in terms of both global pressures and national and regional dynamics. Problems of competitiveness are at least partially due to under-investment, management failures, skills shortfalls and difficulties in interfacing with the railway network. Less easy to resolve structural problems include the great imbalance between imports and exports, heightened regional competition and ongoing political instability in the Great Lakes region.     

Development of ocean carriers' behaviour model focusing on their 'cost and tariff' based on the spatial general equilibrium

Spatial computable general equilibrium (SCGE) theory has been applied to an international trade model to evaluate tariff and fiscal policies of a country. Those models can not be applied for the evaluation of transport policies such as port development and tax/subsidy policy against transportation sectors, since they do not deal with ocean freight and ocean carriers explicitly in the model. Ocean freight often varies with the changes of competitive conditions and/or demand/ supply balances in the short run, while it should reflect the actual expenditure of the carriers in the long run. The model proposed here considers the profit maximization behaviour of ocean carriers, and deals with ocean freight explicitly. The model is applied to four major economic regions; Japan, USA, EU and Asia. A multi-level function composed of the Cobb-Douglas function is adopted to produce reliable parameters of the production function for many industries.

The implications of increased competition among ports for port policy and management

The increased competition faced by ports is more focused than previously on the performance of logistics systems of which the individual terminals in ports are critical hubs. The changes in competitive conditions raise issues about appropriate public port policies and strategies of port managements. This paper argucs that the port industry should (and is) moving in the direction of more harmonized policies based on economic principles. Port policies based on cost recovery from users of port facilities and services need to be adopted as the international standard. The competitive environment favours considerable local autonomy. Port management, in addition to possible direct responsibility for terminal management, needs to focus on activities with economies of scale or scope. Such activities, which span the requirements of terminals and may even warrant inter-port cooperation, enhance the services available for many port users.     

Development of a methodology for estimation of ballast water operation in UK ports

To avoid or mitigate risks associated with introduction of non-indigenous species, it is necessary to monitor and understand the quantity and origin of foreign and domestic ballast water discharged into territorial waters. It is not yet compulsory to report a ships ballast water operations in any ports within the UK. 38 ports have been contacted and their shipping operations from 2003 to 2008have been collected. Despite the diverse nature and format of the data, it has been possible to develop a correlation between the amount of cargo and ballast water operations for every port and hence estimate the potential amount of ballast water discharged. The proposed methodology has been used to estimate the total amount of ballast water discharged in UK waters and at individual ports. Based on this estimation, 20 UK ports with the highest amount of imported ballast water from foreign origins have been identified.     

The ports of the Russian Far East: a management strategy

The recent breakupof the former Soviet Union and the Russian Republic's movement towards a market economy wil require a considerable improvement and expansion of present port facilities in order to handle increasing cargo throughputs effectively. The Russian Far East is expected to increase trade dramatically through imports of foreign goods, exors of natural resources from Siberia and container traffic traversing teh Trans-Siberian landbridge. The ports of the region will be competing with each other to atract foreing investment and to increase central government assistance in order to facilitate development. This article examines;(1) the more important ports of the Far East and the problems they face as they compete to atract investment; (2) the establishment of a Regional Port Authority as a possible management alternative; (3)advantages of a Port Authority in developing the region' ports and fostering future growth. By analysing these data, a management and development strategy can be formulated for the optimum utilization of present resources and the benefi of reginal modernization and development.     

Data processing and telematic work and projects in Western Mediterranean ports

This report which is the object of this summary is the result of Western Mediterranean cooperation both in origin and in execution, during which interviews with over 100 people working in port areas in seven countries were carried out. This has led to a working group involving several professions to promote data processing and electronic data interchange in transport within the area.

CETMO which takes part in these cooperative tasks as an international centre of the United Nations, has drawn up the report. The aim is to provide the group of interested companies and institutions with data on the realities, projects or intentions to develop data processing and telematic systems in the ports of Algiers, Barcelona, Casablanca, Genoa, Lisbon, Marseilles, Tunis and Valencia.

The report presents the results seen from the point of view of the user; the transport operator. Emphasis is therefore placed on system functions and on organizational aspects in order to point out the leaders in port computerization and also the obstacles encountered. The data collected refer to the last nine months of 1988.     

Testing port choice models using physical and monetary data: a comparative case study for the Spanish container trades

ABSTRACT

Transport costs are useful explanatory variables in port choice research. Nevertheless, the availability of such information usually poses a problem. Thus, the formulation of an alternative approach, to be used as a proxy of these variables, would be desirable. The objective of this study is to improve the analysis of container port choice using logit models by adopting physical non-monetary indicators based on maritime distance and ship size. The statistical tests of logit models on port choice using these new variables are compared with the result of using cost variables for the same data set of choice positions. The statistical outcome is good and allows us to present this new approach as a contribution to the literature on port choice modeling.     

Do port security quality and service quality influence customer satisfaction and loyalty?

ABSTRACT

This study uses Kaohsiung Port as a case study to evaluate the relationships between port security quality, port service quality, customer satisfaction, and customer loyalty. For this purpose, a survey was conducted with shipping companies and freight forwarders in Taiwan. The results indicate that port security quality has a direct and positive impact on both port service quality and customer satisfaction; port service quality has a direct and positive impact on both customer satisfaction and customer loyalty; and customer satisfaction has a direct and positive impact on customer loyalty. However, the impact from port service quality is more significant than that of port security quality. Accordingly, this study suggests that Kaohsiung Port should concentrate on improving its service quality in order to enhance customer satisfaction and customer loyalty.     

Inter-firm relationships and shipping services: the case of car carriers and automobile importers to the United States

This paper is an initial exploration of inter-industry relationships and linkages in the context of automobile imports to the United States. It is our contention that the nature and structure of the engagement between automobile importers and shipping lines is central to understanding the evolution of the car carrier trade. Building on the literature on transactions costs, and supply and value chains, we show that the regimes currently governing car carriage services range from markets to vertical integration via network forms of engagement. We illustrate this through a detailed discussion of Japanese inter-firm networks and an examination of automobile import data to the US from 1980 to 2000. The findings raise important questions for future research on the impact of inter-industry relationships in various strategic decisions of steamship lines, shippers and port authorities including port entry, port choice and routeing, technological and investment choices, and trajectories of supply chain development.
