Assessing cognitive load distributions for envisioned task allocations and support functions
other
Information technology provides new possibilities to combine and support operator tasks in order to improve the operational effectiveness and efficiency on board of a ship. The general question is how to design a task allocation and support system that lead to an adequate deployment of the human cognitive resources. Neerincx [1] developed a Cognitive Task Load (CTL) analysis method to address this question systematically during (re)design processes. A brief example application shows the proposed approach: an analysis of different combinations of platform-supervision and navigation tasks with various support functions on the ships bridge of the Royal Netherlands Navy, aiming at an unmanned ship control centre under non-critical situations. Subsequently, we present a first prototype tool for the proposed, systematic exploration of the design space by assessing the operator load for different task allocations and support functions. For envisioned scenarios, the analyst specifies several levels of crew experience, task allocations and support functions, and the simulator subsequently calculates the corresponding load distributions among the crew (including possible occurrences of momentary peak values) and the overall task execution time of the crew.
