Reliability optimization of a redundant system with failure dependencies

Reliability optimization of a redundant system with failure dependencies Haiyang Yu, Chengbin Chu , Ėric Châtelet and Farouk Yalaoui Institute Charles Delaunay (ICD, FRE CNRS 2848), Troyes University of Technology, Rue Marie Curie, BP 2060, 10010 Troyes, France Management School, Hefei University of Technology, 193 Tunxi Road, Hefei, China Abstract In a multi-component system, the failure of one component can reduce the system reliability in two aspects: loss of the reliability contribution of this failed component, and the reconfiguration of the system, e.g., the redistribution of the system loading. The system reconfiguration can be triggered by the component failures as well as by adding redundancies. Hence, dependency is essential for the design of a multi-component system.
