IAHP-Based Comprehensive Evaluation of Upgrade and Modification for Civil Aircraft Avionics System

In the process of rapid development of civil aviation, more and more aircraft will enter the upgrading stage. The modification of the avionics system can improve the flight performance and safety of the aircraft. To realize this objective, it is necessary to comprehensively assess the upgraded and modified avionics system. Firstly, the evaluation model of the upgrade and modified avionics system is established. Secondly, the weight of each layer is derived for the established multi-layer evaluation model using IAHP. After that, a fuzzy comprehensive evaluation is realized based on the evaluation model and weight determined by IAHP. Simulations illustrate the feasibility and effectiveness of the evaluation process and method.
