The society’s main trend for globalisation requires the restructuring of the global transport system as a whole. The ‘Dnieper region’ is no exception, as it needs changes in its practice of organising and managing its process of cargo delivery in accordance with the current trends. This paper considered the main solution directions of this problem in the aspect of ‘container on barge system’ transportation in accordance with the potential of the region. Based on international experience, the competitiveness of the container on barge system can be ensured by applying the different forms of cooperation between the business-players. In the case of horizontal cooperation, it’s raising the problem of distribution of structural elements of the container on barge system during the container-flows adoption. So, the paper proposed the mathematical decision to maximise the use of the linear ship's characteristics by the barge’s loading capacity and by the tug’s engine power.

The paper considers the vessels operating on carriages of bulk cargoes to get the maximum profit for the shipowner as his main goal. The items in search are the long-term contracts of affreightment with some clauses indicated as indeterminate values, that can be described using a range of values. It leads to a range of voyage indicators. The vessels’ deployment for getting the maximum profit depends on the market situation that is to say possible changes in vessels' time-charter rates and freight rates. This paper presents the mathematical model, based on the fleet and volumes of carriages under a set of contracts of affreightment during the due time. It includes the necessity for the commitment fulfilment by owned and time-chartered vessels and takes into account possible changes in freight rates for cargoes carriages. The presented numerical example demonstrates the opportunity for practical implementation of the model.
