Research on Module Division of Commercial Aircraft Based on Analytic Hierarchy Process and Grey Fuzzy Comprehensive Evaluation

The module division scheme of commercial aircraft and other complex system products has a significant impact on the functionality, performance, and cost of the aircraft. To obtain a scientifically sound and rational module division scheme for commercial aircraft, this paper establishes a comprehensive evaluation method for the module division scheme of commercial aircraft based on the Analytic Hierarchy Process (AHP) and Grey Fuzzy Evaluation Theory. A model combining AHP and Grey Fuzzy Comprehensive Evaluation is developed. This method is applied to assess the module division scheme of the forward fuselage structure of a commercial aircraft. The results indicate that the AHP-Grey Fuzzy Comprehensive Evaluation method can yield an optimal module division scheme for the forward fuselage structure, thereby validating the scientific and rational nature of the module division evaluation method for commercial aircraft. The research findings reveal a scientific approach to the module division of complex system products and offer new insights into the module division schemes of such products. Although there are limitations, the results of this study hold significant implications for both theory and practice.
