Information and Communication Technologies for Integrated Operations of Ships
MetadataShow full item record
Over the past three decades, information and communication technologies have filled our daily life with great comfort and convenience. As the technology keeps evolving, user expectations for more challenging cases that can benefit from advanced information and communication technologies are increasing, e.g., the scenario of Integrated Operations (IO) for ships in the maritime domain. However, to realize integrated operations for ships is a complex task that involves addressing problems such as interoperability among heterogeneous operation applications and connectivity within harsh maritime communication environments. The common approach was to tackle these challenges separately by service integration and communication integration, respectively: each utilizes optimized and independent implementations. Separate solutions work fine within their own contexts, whereas conflicts and inconsistencies can be identified by integrating them together for specific maritime scenarios. Therefore, connection between separate solutions needs to be studied. In this dissertation, we first take a look at complex systems to obtain useful methodologies applied to integrated operations for ships. Then we study IO of ships from different perspectives and divide the complex task into sub-tasks. We explore separate approaches to these sub-tasks, examine the connection in between, resolve inconsistencies if there are any, and continue the exploration process till a compatible and integrated solution can be accomplished. In general, this journey represents our argument for an integration-oriented complex system development approach. In concrete, it shows the way on how to achieve IO of ships by both providing connectivity in harsh communication environments and allowing interoperability among heterogeneous operation applications, and most importantly by ensuring the synergy in between. This synergy also gives hints on the evolution towards a next generation network architecture for the future Internet.
