Study on function allocation application in human-machine system

Function allocation is an important part of the human-machine systems discipline. The function allocation screening worksheet (FASW) was researched and applied in the human-machine system. In the FASW, Functions were determined by the analysis of system function flowcharts. Human and machine capabilities based the Fitts list were gotten, and weight of capabilities was calculated through the subjective survey. The result of functions allocation was determined by comparison between evaluation scores for human and machine capabilities. Taking functions in landing phase of aircraft for example, the application of functions allocation was researched by the FASW. The results of function allocation are verified the validity of the FASW. The study of function allocation application could provide the reference for the early design stage of human-machine system.
