Research on Balance of Effective-Cost of Large-Complexity Aircraft Based on Method of Extenics

Abstract

A large number of random and fuzzy factors are involved in the process of development, production and application of large complex aircraft.Seeking for balance between efficiency and cost objectively has become the core issue of life cycle management for large and complex aircraft.The applicability of the theory and method of extenics in the effective-cost equilibrium analysis on large-complex aircraft is proposed, including the overall architecture, matter-element model and application process.Aiming to test the feasibility of extenics and matter element method, an example of a complex aircraft model is introduced and the index system of efficiency and cost measurement is constructed.Through example analysis, it shows that the aircraft cost effectiveness trade off scheme is constrained by its inherent capability, labor cost and material cost.The optimal scheme for weighing the efficiency and cost of complex aircraft is obtained by evaluating the optimality of extenics under multiple constraints.
