Effectiveness Evaluation Of Integrated Avionics System Based On AHP Method

Modem warfare is the comprehensive war of the integration of information, ability and space. To a large extent, its quality depends on the performance of combat aircraft. Integrated avionics svstem is an important part of modern aircraft, and its function affects each mission capability of the aircraft. Evaluating the operational effectiveness of integrated avionics system has important guiding significance to improve the performance of combat aircraft. The thesis studies the effectiveness evaluation technology of integrated avionics system and the main works as follows:(1) The effectiveness evaluation index of integrated avionics system is established, and the hierarchy and the relationship between the various levels of the effectiveness e\ aluation index system of the integrated avionics system are studied.(2) The thesis constructs the judgement matrix to reduce the expert’s subjectivity by using group AHP method and quasi-optimun consistent matrix to solve the inconsistent problem of judging matrix by using least square principle.(3) The bottom indicators are divided into non-quantifiable indicators which obtain the evaluation vector by using experts evaluation method and quantifiable indicators which obtain the evaluation vector by using the utility function method and grey AHP method when the vector of the underlying index is calculated.(4) The effectiveness evaluation system simulation software of integrated avionicssvstem is developed to simulate the established effectiveness evaluation index system.After verification, the proposed effectiveness evaluation method based on improvedAHP is scientific, reasonable. The simulation software of integrated avionics system hasstrong reliability and provides convenient for the further research effectiveness evaluation olthe integrated avionics system.
