Purpose: This paper discusses the current state of research on tactical planning in tramp shipping problems. The constantly changing demands in operative tramp shipping make tactical or strategical, i.e. longer-term planning, in comparison to op-erative planning more complex. The purpose of this paper is to describe solutions to tactical planning difficulties in tramp shipping and to point out future research direc-tions. Methodology: For this paper, a systematic literature review of journal articles and book chapters of the last ten years is conducted. The findings of this search are ana-lyzed and reviewed. Thus, different planning problems and their solutions are iden-tified. Findings: Planning problems in tramp shipping are clearly distinct from planning problems in liner shipping as tramp shipping is subject to considerably more uncer-tainties. Due to the high degree of uncertainties in tramp shipping longer-term plan-ning is challenging. Consequently, the results of research on tactical planning prob-lems in liner shipping cannot be transferred directly to tramp shipping. Originality: This paper provides a comprehensive overview of strategic and tactical planning in tramp shipping as presented in the literature.

Purpose: The sustainable development of Arctic maritime supply chains requires an effective balance between economic growth, environmental protection and social relations. Existing Arctic development projects are often distinguished by single-cri-terion decision making - economic growth to the detriment of other components. The paper aims to analyze existing approaches and practices of Arctic supply chains development from a sustainable development viewpoint. Methodology: Best practices of other industries are identified by a thoroughly liter-ature research of relevant publications and developing a model for sustainability is-sues in Arctic maritime supply chains. The model compromises relevant indicators in regard to economic, social and environmental performance for the Arctic region. Findings: The result of this paper will be a thoroughly overview over current sustain-ability issues in the Arctic framework (economic, social and environmental). Findings for example will be how companies adjust to the ban of using heavy Sulphur fuel in the Arctic or social and economic changes in remote areas due to more shipping in the Arctic. Originality: The originality of the research is defined by the sustainability viewpoint on the problem: the combination of social, economic as well as environmental issues is the main focus of this paper especially with a focus on remote areas of the Arctic.
