Port choice by intra-regional container service operators : an application of decision-making techniques to liner services between Malaysian and other Asian ports

Intra-regional container service operators are challenged to design regular and reliable liner services connecting regional ports at the lowest cost and shortest transit time while considering customer demand. This paper focuses on the selection of ports of call in regular intra-regional container services, an under-researched part of the container shipping market. A combination of decision-making techniques (i.e. Analytical Hierarchy Process, fuzzy link-based and Evidential Reasoning) are presented to assist intra-regional container service operators in selecting ports of call. The proposed methodology is empirically applied to container services between Malaysian and other nearby Asian ports. While Port Klang is the main gateway to Malaysia, the results show that other Malaysian ports should play a more prominent role in accommodating intra-Asian container services. This research can assist maritime stakeholders in evaluating intra-regional port-to-port liner service configurations. Furthermore, the novel mix of decision-making techniques complements and enriches existing academic literature on port choice and liner service configuration

Modelling the impact of liner shipping network perturbations on container cargo routing: Southeast Asia to Europe application

Understanding how container routing stands to be impacted by different scenarios of liner shipping network perturbations such as natural disasters or new major infrastructure developments is of key importance for decision-making in the liner shipping industry. The variety of actors and processes within modern supply chains and the complexity of their relationships have previously led to the development of simulation-based models, whose application has been largely compromised by their dependency on extensive and often confidential sets of data. This study proposes the application of optimisation techniques less dependent on complex data sets in order to develop a quantitative framework to assess the impacts of disruptive events on liner shipping networks. We provide a categorization of liner network perturbations, differentiating between systemic and external and formulate a container assignment model that minimises routing costs extending previous implementations to allow feasible solutions when routing capacity is reduced below transport demand. We develop a base case network for the Southeast Asia to Europe liner shipping trade and review of accidents related to port disruptions for two scenarios of seismic and political conflict hazards. Numerical results identify alternative routing paths and costs in the aftermath of port disruptions scenarios and suggest higher vulnerability of intra-regional connectivity

Transshipment port selection in the strait of Gibraltar

JEL Classification System: L920; R420The purpose of this study is to understand which factors impact more in the transshipment container port selection process in Gibraltar range. Analytical Hierarchy Process is applied through a survey. A random sample of 27 respondents ranked criteria based on pairwise comparisons and evaluated transshipment container ports through a 5-point Likert scale. The results suggest that vessel turn-around time, the proximity to the main navigation routes and the handling and storage cost of containers are the criteria that most impact in the transshipment port selection process. Further analysis could also extend to the switching costs in the transshipment business through previous cases, framing a cost-benefit analysis. Another future direction for research is a study in transshipment port selection with a higher number of respondents, comparing different perspectives, from maritime carriers to terminal managers, amongst others stakeholders. The results suggest that Port of Algeciras is the one that most fulfills productive criteria; Port of Tanger is the most competitive regarding costs; Port of Valencia has been able to balance transshipment and gateway services. This study is one of the first attempts to demonstrate the theoretical concepts of transshipment in one of the busiest bottleneck areas. The value of this study relies that academics and professionals may have supporting evidence that costs and productivity are the most valuable transshipment port criteria. The current situation in the transshipment in Gibraltar range could also be valued by port managers to define and prioritize new investments.O objetivo deste estudo é perceber quais os fatores mais relevantes na tomada de decisão de um porto de contentores de transshipment na zona do Estreito de Gibraltar. O método Analytical Hierarchy Process é utilizado através da construção de um questionário. Os 27 inquiridos hierarquizaram um conjunto de critérios através de comparações aos pares e avaliaram os portos através de uma escala de Likert de 5 níveis. Os resultados obtidos sugerem que o tempo de transbordo, a proximidade com as principais rotas marítimas e o custo de transbordo e armazenagem de contentores são os critérios mais relevantes aquando a tomada de decisão. É recomendada uma maior investigação, abrangendo os custos de troca de um porto transshipment, através do estudo de casos anteriores, construindo uma análise custo-benefício. Outra possibilidade passa pelo estudo do processo de seleção de um porto transshipment com um maior número de inquiridos, comparando perspetivas de diferentes intervenientes. Os resultados sugerem que o porto de Algeciras é o que melhor preenche os critérios de produtividade; o porto de Tanger é o mais competitivo em termos de custos; o porto de Valência tem sido capaz de apresentar um equilíbrio como porto de transshipment e como porto gateway. Este estudo é um dos primeiros a aplicar os conceitos teóricos associados ao transshipment a uma das áreas geográficas mais relevantes para o negócio. Académicos e profissionais dispõem assim de evidência prática de que os custos e a produtividade são dos critérios mais relevantes no processo de decisão, ajudando-os a definir e priorizar novos investimentos
