An intelligent operator support system for dynamic positioning

This paper proposes a human-centered approach to Dynamic Position-ing systems which combines multiple technologies in an intelligent operator sup-port system (IOSS). IOSS allows the operator to be roaming and do other tasks in quiet conditions. When conditions become more demanding, the IOSS calls the operator to return to his bridge position....

Beyond macrocognition: The transaction level

The purpose of this paper is to respond to a number of developments in the past 15 years in the areas of NDM and macrocognition. In my view, these developments necessitate the definition of a new systems level, extending and modifying Newell’s (1990) "bands of cognition". I will argue that what has been called 'microcognition' may best be viewed...
