Abstract
A decomposition-coordination optimization method termed as analytical target cascading-based exterior penalty function (ATC-EPF) is proposed to investigate the reliability allocation aiming at the low computational efficiency for large complex systems. Firstly, the optimization model is established via ATC-EPF, which is decomposed into the models of subsystems. Then the subsystems are calculated in parallel, which reduces the computational cost greatly in the condition of keeping the computational accuracy. The results are fine which are verified by two study cases including one numerical case and one engineering case. This research is of great significance to large-scale system planning and design.
