Abstract

Aiming at the correlation among redundant components in optimization of system reliability redundancy, this paper makes use of Gumbel Copula function to describe this correlation and then the redundancy optimization model is improved. To solve the improved model, this paper uses the GAG1 heuristic algorithm. The sensitivity factor of this algorithm is corrected according to Gumbel Copula function. Finally, the numerical example indicates the feasibility, validity and practicality of this method.
