Considering the dynamic reconfiguration of the Distributed Integrated Modular Avionics (DIMA) system, the dynamic reconfiguration strategy and reconfiguration process are analyzed, and a joint k/n (G) reliability model for the DIMA system is constructed. An experimental analysis of the comprehensive display function residing in the DIMA system is carried out. The relationship between reliability and time of the system reconfiguration process is discussed, and the change of reliability curve is given using the general k/n (G) reliability model. Comparative analysis is conducted to show the applicability and rationality of the joint k/n (G) model. Through the parameter sensitivity analysis, the impact of different model configuration parameters on the system reliability is observed. The results can provide effective guidance for improving the reliability of the dynamic reconfiguration process of the DIMA system and optimizing resource allocation.
