Decision Model of Aero-Engine Design Integration Platform Implementation Solution Selection Based on Number Interval Number with Priority Order

Abstract

Considering the fuzzy factors in the aero-engine design integration platform implementation solution selection, using the prioritized interval number evaluation method, the implementation model of the aero-engine design integration platform implementation solution selection is established, and the priority relationship is calculated according to the relative distance between each attribute and the ideal point. Through the calculation of the relative distance between the interval value and the negative ideal point, the single evaluation value is obtained. Finally, the comparison result of the pre-selected scheme is obtained by analysing and solving the preferred model. The model comprehensively considers the determining factors in the optimization process and uncertain factors, clear logic, and the best results obtained are comprehensive and reasonable.
