In maritime transportation of automobiles, roll-on/roll-off (ro–ro) shipping companies operate liner shipping services across major trade routes. Large ro–ro shipping companies are well placed to offer end-to-end integrated logistics services to auto manufacturers engaged in international trade of vehicles. Therefore, we present a new mixed integer programming model for fleet deployment including inventory management at the ports along each trade route. Due to the complexity of the problem, a rolling horizon heuristic (RHH) is proposed. The RHH solves the problem by iteratively solving sub-problems with shorter planning horizon. Computational results based on real instances are presented.

Transportation Research Part E: Logistics and Transportation Review

This paper analyses the modal shift from a primary road-based to coastal shipping-based freight distribution. A mathematical model is developed to optimize the coastal shipping route planning under a multimodal distribution scenario. The model is applied to a case study of the outbound automotive logistics in India. Exploratory insights on the enablers and challenges to adopting coastal shipping-based distribution are presented along with the route configuration and the level of modal shift achievable based on the model results. The results of the study suggest that the current business and regulatory environment is appropriate to achieve almost one-third shift to intermodal coastal shipping, although investments in infrastructure and substantial cost reductions in ship and port operations need to be implemented to ensure further modal shift. This article is a revised and expanded version of a paper entitled Enhancing the role of coastal shipping in finished vehicle distribution—a viability study presented at The International Association of Maritime Economists (IAME) Conference, Kyoto, Japan; 27–30 June 2017.

Analysing the modal shift from road-based to coastal shipping-based distribution – a case study of outbound automotive logistics in India

This paper addresses the fleet deployment problem and in particular the treatment of inventory in the maritime case. A new model based on time-continuous formulation for the combined maritime fleet deployment and inventory management problem in Roll-on Roll-off shipping is presented. Tests based on realistic data from the Ro-Ro business show that the model yields good solutions to the combined problem within reasonable time.

A new formulation for the combined maritime fleet deployment and inventory management problem

We present a tactical maritime fleet deployment problem in roll-on roll-off (ro-ro) liner shipping scenario, which deals with optimally assigning planned voyages to the available vessels in a fleet to determine the routing and scheduling of vessels across the given trade routes, in order to maximize profit or minimize cost. This paper presents a new model for a fleet deployment problem in liner shipping that considers inventory constraints at ports for vendor managed cargo in each route and determines optimal shipment sizes for those cargoes, between corresponding origin and destination ports. We present an MILP formulation for the problem described above, a scheme to generate appropriate datasets, and computational results for the problem.
