The containership loading problem

Abstract: The efficiency of a container terminal depends primarily on the smooth and orderly process of handling containers, especially during the ship's loading procedure. The loading plan is mainly determined by two considerations: ship stability and minimum number of rehandles required. These two basic considerations are often in conflict. Most containerships have a cellular structure, imposing a strong restriction on the order of the container loading sequence. To preserve a ship's stability, some containers may be stowed in a ship hold in middle vertical locations. A similar loading problem exists in the stacking of yard containers. If these containers are stacked in the yard under others which are to be picked up later, then the loading process requires a number of container rehandles. This paper is concerned with a ship's container load planning which satisfies these two considerations and minimises the number of rehandles.

FDI Attractiveness in Greece

Abstract: This paper investigates the foreign direct investment (FDI) attractiveness for Greece as a host country compared with the rest of the EU countries. The main objective of this work is to identify the factors that improved or worsened Greece’s attractiveness during the last few years. An econometric model and a comparative index of FDI attractiveness have been constructed in order to identify the differences in the attractiveness of the countries. The results obtained prove that during the last few years Greece’s attractiveness as a host country for FDI has not only improved, but it also has a downward trend. The factors identified as crucial for the low FDI attractiveness in Greece are inefficient public governance, high taxation, inefficient infrastructure, and general macroeconomic conditions.
