Abstract:

Reliability redundancy design optimization is one of the focuses of aerospace equipment research and development work. Based on the optimization of system reliability balance, this article proposes a new concept of collaborative balance, which utilizes unit collaborative changes to further optimize the reliability redundancy design of complex systems. The proposed algorithm fully considers the impact of changes in redundant units on performance parameters such as reliability, cost, volume, quality, and power consumption of complex systems, and can solve various reliability redundancy design optimization problems. The calculation results show that the reliability redundancy design optimization algorithm based on unit collaborative balance can effectively achieve the optimization goal of reliability redundancy design, with the advantages of low computational cost and high efficiency.
