Application of QFD-AHP in Decision-making of Aircraft Trajectory Calculation Programme

In this paper, a method of selecting the best strategy for parameters calculation of aircraft trajectory was proposed. The optimal scheme can be selected in the multiple calculation schemes of trajectory measuring parameters which are obtained by optical device, continuous wave radar system, pulse radar system, GPS and so on. By constructing the estimation matrix, the various factors that affect the processing of track parameters are coupled together. QFD and AHP are combined to decompose the decision problem into several single criteria evaluation problems. On this basis, comprehensive evaluation is carried out, which avoids the blindness when the decision maker adjusts the judging matrix, and it can make the improved judging matrix to retain the original information more. The processing results show the effectiveness of the proposed method.
