Experimental Evaluation Of A Joint Cognitive System For 4d Trajectory Management, Rolf Klomp, Clark Borst, Max Mulder, Gesa Praetorius, Martijn Moij Nov 2013

Experimental Evaluation Of A Joint Cognitive System For 4d Trajectory Management, Rolf Klomp, Clark Borst, Max Mulder, Gesa Praetorius, Martijn Moij

Effective joint human-automation coordination is essential in order to support the central role of the human operator in foreseen future trajectory-based air traffic operations. The SESAR WP-E project C-SHARE aims to achieve this by taking a Cognitive Systems Engineering approach, based upon accomplishing joint human and automation cognition through a shared representation of 4D-trajectory management. In foregoing research, a work domain model and a joint human-machine interface has been developed to support the human operator in the task of en-route 4D trajectory re-planning. This paper presents the findings of two experiments that aimed to determine the effect of both the …


“Under Dangerous Conditions” – Safety Construction And Safety-Related Work Onboard Of Merchant Vessels, Gesa Praetorius, Monica Lundh May 2013

“Under Dangerous Conditions” – Safety Construction And Safety-Related Work Onboard Of Merchant Vessels, Gesa Praetorius, Monica Lundh

Gesa Praetorius

The following paper presents findings from a qualitative study conducted on board of two merchant vessels. Interviews and observations have been used to obtain insights in how safety is defined and promoted by the personnel working on board. The merchant vessel, the crew and the single mariner are identified to be part of a socio-technical system displaying three levels of system aggregation; person-centred, crew-centred, and vessel-centred. The common ground of a crew, an overlap of the individual mariners’ experience and knowledge, is identified as a basis for trust and predictability of action on board, which is a necessity to be …


Safety Is Everywhere-The Constituents Of Maritime Safety, Gesa Praetorius, Margareta Lützhöft Dec 2010

Safety Is Everywhere-The Constituents Of Maritime Safety, Gesa Praetorius, Margareta Lützhöft

Gesa Praetorius

Although maritime safety is one of the key terms in regulation, guidelines and recommendations, such as SOLAS (International Convention for the safety of life at sea (IMO, 1974), in the shipping domain, there is, to the best of our knowledge, neither an explanation of this specific type of safety nor any explicit understanding on how it is promoted by those who work on board of merchant vessel. This qualitative study approaches maritime safety from a crew perspective and discusses what constituents should be considered to be part of maritime safety.
