QUEUEING ANALYSIS OF THE AIR TRAFFIC CONTROLLER'S WORK LOAD

In an effort to increase air traffic control (ATC) system performance, various controller aids (e.g., automation) are constantly being developed. The qualitative relations between work-load measures (or stressors), strain, fatigue, and the performance the man in the system are reviewed. A number of stressors, including the work-load magnitude (i. e., minimum utilization time per unit time), delay in ATC task execution due to excessive activity, and mental-image updating requirements are identified and discussed. With the various ATC tasks competing for the man's attention and under the single-channel hypothesis of man's information-processing activity, a queueing model is presented.
