Control and resilience within the maritime traffic management domain
Artikel i vetenskaplig tidskrift, 2014

This article presents research conducted within the Vessel Traffic Service (VTS) domain. VTS is a service that is provided close to ports and geographically challenging areas to support merchant vessels in their navigation. Although VTS is legally an advice and assistance service, applying concepts from Cognitive Systems Engineering and Resilience Engineering can highlight how the joint human-machine system works to promote safe and efficient traffic movements. The VTS is a Joint Cognitive System that maintains control through a mixture of opportunistic and tactical control. Strategic control is only partially supported by the higher levels of system aggregation that provide the basis for defining daily operations within the settings of the VTS. To increase the VTS system's ability to anticipate, respond, monitor, and learn, and therefore the ability to be resilient, there is a need to promote more strategic and tactical control within daily operations.
