Brief literature review and background information on the GCS is provided. As the GCS market matures, new technological and network demands evolve. On the basis of a small-scale private R&D project, some basic attributes of hub-and-spoke operations, involving existing vessels and innovatively designed high-speed passenger vessels, are discussed. The paper focuses on network and marketing issues, and aims to trigger further discussion on this issue of special interest. Exploring the possibility for hub-and-spoke services in the Greek Coastal System

Numerous techniques usually based on models which simulate the weather and loading conditions are used in order to achieve optimum adjustment. Nevertheless, perfect steering is not yet accomplished mainly due to the infinite number of different situations during sea passages. We claim that a CBR approach which selects the best out of a finite, pre-installed set of device configurations using specific criteria can compete with existing methods and continuously improves itself during the ship's life cycle.

Its ecosystem has become vulnerable to pollution and chemical pollutants which may have changed the coastal ecosystem's biogeochemistry. This study identifies the pollution sources, status and pollution effect of Xiamen Bays ecosystem. This paper reviewed the present management system and policy in this ecosystem. The authors suggest that environmentally sound technology should be adapted for pollution prevention, control and remediation in Xiamen Bay. Sustainable management may help achieve the pollution protection of its whole ecosystem. Pollution status and sustainable management of Xiamen Bay in China: a brief review

Its tools are those of Managerial Economics and Microeconomics. First, the conditions of demand and supply are examined looking in particular into the number of companies in each route, free entry-exit as well as other variables. Then the main characteristics of oligopoly are set. Finally, we have calculated the Herfindahl-Hirschman index for the structure of markets. We used the market share of each company in each route for passengers, cars and Lorries. Patras-Ancona found oligopoly; Patras-Bari is monopoly as well as Patras-Brindisi; Patras-Venice is duopoly.

We suppose that: System of Systems (SoS) can be identified by its distinguishing characteristics; Maritime Transportation Systems (MTS) can be considered as a SoS in which constituencies seek their own goals; and its integrated objective is to transfer goods safely and efficiently. Based on these premises, we present our management framework. The proposed framework enables us to engineer and manage MTS more effectively from a System of Systems Engineering (SoSE) perspective.
