ABSTRACT
Reliability is an important characteristic of civil aviation products and therefore the basis of aircraft safety and economy. With the increasing complexity of civil aircraft, the analysis of potential failure modes and propagation laws of products using traditional reliability analysis methods based on manual inference has become difficult, thereby motivating the need to investigate the methodology adapted to complex systems. Model-Based System Engineering (MBSE) is considered an effective method for designing complex systems. In this study, we investigate the principle and method of integrating reliability design in the MBSE process; that is, it integrates the requirement-driven reliability and evaluation process with the typical MBSE technology process. For this purpose, we study the mapping methods of the MBSE design model and the reliability model, which can automatically establish the reliability model through the extended definition of the design model, thereby improving the efficiency and accuracy of reliability design. Finally, we consider the design process of a flight control system in order to demonstrate the feasibility and effectiveness of the proposed method.
