Abstract:
The mission reliability of utility management computer is critical and essential to aircraft flight safety, an effective way to improving the mission reliability is dual redundancy design.Departure from the study of two commonly used reliability model, we use the bridging model for dual-redundant design of utility management computer.Fault-tolerant mechanism analysis of bridging model proves that the dual-redundant design can effectively improve the mission reliability of utility management computer, and has a certain practical value.
