Team Task Complexity of Traffic Dispatchers in Operating Control Center:A Network-based Concept

Abstract

A clear concept of team task complexity was proposed in this paper, aiming at understanding the particularity of the train dispatching team task in operating control center (OCC). Based on the review of the task complexity construct and definition, and the analysis of the team task feature under different levels of automation, a team task model was built. This team task network took the events in the task as nodes and the information cues between events as edges, which included both macro and micro impacts on the complexity. The definition of team task complexity was proposed as the combine impact of the macro complexity of the structure of caused by the links of all the events and the micro complexity of each event. Then four emergency senses of team task network models were built, and the complexity of these models could be intuitively differentiated. Finally, some application of this concept and following research plan was mentioned.
