In the literature, mostly, under the heading of maritime logistics, classical sea transportation issues have been studied. In actual fact, with broader scope, maritime logistics is a different field under the logistics theme and sea transportation is just one of the functions that must be carried effectively and in an integrated manner with other logistics functions. This chapter focuses on the maritime logistics functions which were selected by the authors in accordance with the gap in the literature, namely transportation and traffic management, inventory management, demand forecasting, material handling, and packaging and labelling. In addition to the maritime logistics functions; port logistics, green maritime logistics and decision problems in maritime logistics topics are handled deeply with the aim of completing the skeleton of the maritime logistics concept by which an understanding of the clear definition of maritime logistics can be achieved. The practitioners can gain more integrated and holistic viewpoint about maritime logistics with the help of this chapter.
