Man-machine function allocation based on fuzzy analytic hierarchy process

Function allocation is an essential step during the design process of complex man-machine systems. How to assign system functions reasonably between men and machines is the emphasis and difficulty of complex man-machine system design research. Fully considering several significant factors influencing man-machine function allocations, this paper comes up with an allocation methodology based on fuzzy analytic hierarchy process on the basis of the difficulties to quantify relative weights of each factor during the practical allocation process. At last, we take the cruise stage during the aviation flight process of the civil aircraft as a practical example. The analysis result of the example demonstrates the method mentioned above is feasible and effective.
