Fleet deployment in liner shipping: a case study

The fleet deployment problem is an important planning problem in liner shipping. It deals with optimally assigning voyages to available vessels in the fleet and determining vessel routes and schedules in a way that minimizes costs or maximizes profit. This paper presents a new model for a fleet deployment problem in liner shipping, and we also propose a multi-start local search heuristic to solve the problem. The heuristic has been embedded in a prototype decision support system (DSS) that has been implemented and tested at Höegh Autoliners, a major global provider of ro-ro (roll-on roll-off) vehicle transportation services. The heuristic was able to produce high-quality solutions within a few minutes to a real planning problem with more than 55 vessels and 150 voyages over a planning horizon of 4–6 months. Tests indicated that the solutions suggested by the DSS gave between 2 and 10% improvements compared with solutions from manual planning. What is almost equally important is that using the DSS can ease the planning process.

Opportunities for increased profit and reduced cost and emissions by service differentiation within container liner shipping

This paper investigates opportunities for increased profit and reduced emissions and cost by service differentiation within container shipping. Traditionally the strategy among the container lines has been profit maximization by utilizing economies of scale through the building of larger and faster vessels. In 2008, the financial crisis in combination with higher fuel prices put an end to this progress and in today’s market operators are basically trying to survive by providing standardized services at the lowest possible cost. This study investigates alternative strategies and the results indicate that container lines should provide two different services instead of one standardized service. A fast service to be more competitive versus air freight for fast-moving goods and a slow service to be more competitive versus traditional shipping types for transport of minor bulk, break bulk, liquid bulk and project cargo.

Green Maritime Logistics and Sustainability

Abstract The environmental consequences of international trade and transport have gained importance as a result of the current climate debate. Products are increasingly being produced in one part of the world, transported to another country and then redistributed to their final country of consumption. Since more than 80% of world trade tonnage measured in metric tons is carried by seagoing vessels, maritime transport will continue to be a core part of most supply chains while rail and road mainly are used for hinterland transport and to and from ports. This chapter presents a methodology for assessing the environmental impact of maritime transport and transport in general, with a specific focus on greenhouse gas emissions. The first section gives an introduction to why Green Maritime Logistics and Sustainability are important topics, while the second offers a framework for measuring greenhouse gas emissions (GHG) for transport systems. The third section presents a model for measuring seaborne transport and its greenhouse gas emissions, and in the fourth section we compare greenhouse gas emissions from different modes of transportation.

Information Technology in Maritime Logistics Management: A Case-Based Approach from CoA to SLA

Abstract A trend in modern supply chain management has been to substitute information for inventory. In this chapter, an approach to how information and communication technology can be used to achieve this in a maritime logistics context is outlined and described based upon a bulk shipping case. The approach used is based on data-driven modeling and analysis, in which current logistics and commodity storage costs are benchmarked against a “best possible solution.” To make a new solution operative, a change should be made based upon an analytical decision-making approach, ICT infrastructure development, and inter-organizational development. Thus, the proper use of analytical and transactional information and communication technology in maritime logistics would enable logistics chain stakeholders to track stock levels and ultimately allocate vessels to move cargo when that is logistically most cost effective. Further, this could support a development in the contractual relationships between producer and shipping line changing from a Contract of Affreightment to a Service Level Agreement relationship. There is room for enhanced use of information and communication technology to provide decision and operational support at strategic, tactical, and operational levels within maritime logistics. This chapter explains some of the driving forces for this, together with a tested approach and method for this, given into a specific, practical case.
